Here, we provided a biogeographical snapshot of the variability of life-history traits of eels (Anguilla anguilla), across a large proportion of their natural distribution range. Silver eels (n = 99) were collected across eleven European catchments to investigate how life-history traits vary along geographical and saline habitats, as it was inferred from the Sr:Ca ratio in otoliths. Among 13 life-history traits tested, 3 of them such as total length, body or liver weight were related to geographical coordinates. Overall, eels grow faster in southern Europe and migrate earlier suggesting that the silvering process is related to the local growth conditions more than fish age. The salinity profiles revealed by the otoliths’ Sr:Ca ratios indicate that eels with a brackish life-history generally grow faster, reach larger size-at-age, and have a better condition than eels living in freshwater. This observation associated with the lower abundance of the sanguivorous swimbladder nematode, Anguillicola crassus, confirms the importance of brackish areas for sustaining the eel production. A large proportion of the observed variation of life-history traits remained unexplained by the biogeographical trends and salinity condition, which suggests that other drivers act at the catchment scale.

Thus, human obstacles to fish migration like dams and hydropower plants should enable efficient management measures ensuring safe passage for eels during the migration. In order to provide a quick and efficient assessment of eel conservation measure applied to the sluice gates of a large floodplain lake, we implemented a novel evaluation method using predictions on past migration seasons when no management measure were applied. For this purpose, we collected acoustic telemetry monitoring data over three migration seasons and fitted a predictive model based on Boosted Regression Trees (BRTs) to describe the influence of environmental parameters on migration. The water level difference over two days proved to be decisive, along with early migration occasions in the season, as an increase of at least 10 cm water level was associated with a sharp increase of migration probability. We then used the BRT model to predict migration occasions at the dam over 8 past seasons and forecast the impact on escapement of management measures if they had been applied. Thanks to this original prospective assessment of dam management measures, we identified an enhanced opening decision rule, capable of increasing the eel escapement for each year of the study. The management measure is particularly efficient during the years with poor hydrological conditions (i.e. droughts), that is the periods with the lowest initial escapement rates. Finally, efficient management measures to increase silver eel escapement were based on increasing the number of gate opening days by only a few days per year (c.a. 15%). However, the management measure only focused on silver eel migration, so that further investigations should consider the impacts of other threats occurring during the life cycle. This study also provides a highly operational approach for fast evaluation of conservation measures, avoiding lengthy and expensive monitoring campaigns of classical ex-post assessments. %B Journal for Nature Conservation %V 67 %P 126192 %8 Jan-06-2022 %G eng %U https://linkinghub.elsevier.com/retrieve/pii/S1617138122000656 %!

Here, we used otolith multi-elemental signatures to reconstruct life sequences of European silver eels within an obstructed catchment, just before the removal of hydropower dams. Beyond providing an initial state, we hypothesized that otolith signatures can provide crucial information on the way eels use the watershed. Indeed, their spatial distribution is expected to shape life-history traits, including condition coefficient, trophic level, growth rate, or infection by metazoan parasites. While Sr:Ca and Ba:Ca ratios were complementary in tracing fish movements between freshwater and estuary, the Ba:Ca variations allowed to discriminate three freshwater sectors. The eels assigned to the midstream sector were more mobile and exhibited lower growth rates, probably in response to higher competition at the vicinity of dams. While most eels are currently produced by downstream and midstream sectors, eels assigned to upper reaches of connected tributaries generally display higher richness in native parasite and higher body condition and lipid reserve, known to promote the success of migration and reproduction. In the near future, the dam removals will represent an outstanding experimental framework for evaluating impacts of catchment reconnection. %B Hydrobiologia %8 Sep-03-2022 %G eng %U https://link.springer.com/10.1007/s10750-022-04833-9 %!

Forecasting the phenology of fish migration is thus critically important to implement management actions aimed at protecting fish during their migration.
In this study, an 11‐year monitoring survey of Atlantic salmon smolts (Salmo salar ) from the Ourthe River, Belgium, was analysed within a European Special Area of Conservation to improve the understanding of environment‐induced spring migration. A logistic model was fitted to forecast smolt migration and to calculate phenological indicators for management, i.e. the onset, end, and duration of migration, while accounting for the influence of photoperiod, water temperature, and hydrological conditions.
The results indicated that the photo‐thermal units accumulated by smolts above a 7°C temperature threshold was a relevant proxy to reflect the synergistic effect between temperature and photoperiod on smolt migration. After integrating the effect of river flow pulses, the model accurately explained the inter‐annual changes in migration timing (R2 = 0.95). The model predictions provide decisive management information to identify sensitive periods during which mitigation measures (e.g. hydropower turbine shutdown, river discharge management) should be conducted to promote smolt survival.
The model was used to predict phenological characteristics under future scenarios of climate change. The results suggest a joint effect of hydrological alterations and water warming. Temperature increases of 1–4°C were associated with earlier initiation of migration, 6–51 days earlier, and spring flood events greatly influenced the duration of the migration period. Accordingly, the combined effects of human‐induced modifications of the hydrological regimes and increasing temperatures could result in a mismatch between the smolt and favourable survival conditions in the marine environment. %B Aquatic Conservation: Marine and Freshwater Ecosystems %8 Apr-07-2021 %G eng %U https://onlinelibrary.wiley.com/doi/abs/10.1002/aqc.3382 %!

This study provided new information about the position of leptocephali within the functional structure of microbial plankton and other food web components of the western South Pacific (WSP) region at a large geographic scale including the New Caledonia, Fiji, and Samoa islands. The hydrographic structure varied with latitude, and nutrient levels were generally low but somewhat variable. Stable isotopic signatures were examined in relation to the 3 current zones of the eastward flowing South Equatorial Countercurrent (SECC; north), the westward South Equatorial Current (SEC; mid-latitudes), and the eastward South Tropical Countercurrent (STCC; south), and all zones were found to be primarily based on a heterotrophic planktonic functioning that were co-limited by inorganic nitrogen and phosphorus, with biomasses of planktonic groups varying with depth. Isotopic signatures of leptocephali were compared to the signatures of other mesozoplankton, micronekton, and Trichodesmium components of the food web, and in relation to the signatures of particulate organic matter (POM) that varied among the 3 collection depths. The isotopic signatures of six taxa of leptocephali, other taxonomic groups and POM showed interesting variability according to latitude and among some stations. The presence of Trichodesmium at the surface in the STCC zone influenced the isotopic signatures of POM and thus the signatures of leptocephali. The signatures of leptocephali were therefore linked with the overall food web and were consistent with the larvae feeding on marine snow components of POM. The two apparent groups of leptocephali with different isotopic signatures that have also been observed in other oceanic areas may be explained by feeding behavior at different depths or on different types of marine snow. %B Progress in Oceanography %V 182 %P 102264 %G eng %U http://www.sciencedirect.com/science/article/pii/S0079661120300021 %R 10.1016/j.pocean.2020.102264 %0 Journal Article %J Journal of Environmental Management %D 2020 %T Resolving the trade-off between silver eel escapement and hydropower generation with simple decision rules for turbine shutdown %A Teichert, Nils %A Tétard, Stéphane %A Thomas Trancart %A Eric Feunteun %A Anthony Acou %A de Oliveira, Eric %B Journal of Environmental Management %V 261 %P 110212 %8 Jan-05-2020 %G eng %U https://linkinghub.elsevier.com/retrieve/pii/S030147972030147X %!

Where downstream passage solutions are complex to develop, turbine shutdown appears as an effective management solution to protect silver eels during their river migration toward spawning areas. However, the definition of operational decision rules for turbine shutdown is challenging due to the duality between the benefit for eel conservation and the concomitant cost in term of hydropower production. Here, we proposed a decision framework for turbine shutdown based on simple hydrological criteria to guide negotiations between stakeholders toward a trade-off between silver eel escapement and hydropower generation. Eel migration was assumed to be triggered by a minimum river flow associated with a minimum discharge pulse, so that threshold values can be directly implemented as decision rules for turbine shutdown. To estimate relevant thresholds, a generic methodological framework was developed to generate alternative decision rules from data collected at hydropower plants, which can include telemetry surveys and estimates of eel abundance. A multiple-criteria decision analysis was then conducted to rank alternatives and to determine the best compromise between promoting silver eel escapement and limiting turbine shutdown duration. Graphic outputs can help stakeholders to understand the competitive interests between eel conservation and hydropower production, while visually identifying a range of consensual alternatives to support negotiations in the choice of operational thresholds. The method was illustrated for three river systems in Europe featured by distinct hydrological conditions and can be applied in other areas, providing that eel monitoring surveys and flow data are available. %B Journal of Environmental Management %V 261 %P 110212 %G eng %U http://www.sciencedirect.com/science/article/pii/S030147972030147X %R https://doi.org/10.1016/j.jenvman.2020.110212 %0 Journal Article %J Nature Communications %D 2020 %T Stable species boundaries despite ten million years of hybridization in tropical eels %A Barth, Julia M.

We aimed to identify the impact of permanent swing mooring on the fast-growing seagrass Zostera marina in a mega-tidal area. Coupling the hydrodynamic MARS3D model to simulate mooring chain movements and in situ measurements of plant traits, we analyzed the structural responses of the eelgrass bed to scraping disturbance in the western English Channel (France). A comparison of the results with a reference site without any permanent swing boat mooring showed a significant impact on eelgrass structure (shoot density, leaf size, leaf dry weight), depending on the direction and distance from the mooring. Zostera marina was absent close to the mooring fixation point in three out of the four directions we evaluated. Beyond 5 m, the canopy height remained lower than in the reference site, most likely due to regular disturbances by mooring chains. Conversely, shoot density beyond 5 m was higher than in the reference site. This adaptive response counter-balanced the decrease in canopy height at these distances. The fluctuations of the structure of the eelgrass cover (number of shoots, leaf length) at a small spatial scale was clearly in accordance with the scraping intensity simulated by the MARS3D model. The tidal currents coupled to tidal amplitude variability imply a small-scale heterogeneous effect of permanent mooring on the benthic compartment, previously undetected by an aerial survey. The present results highlight the interest of coupling approaches so as to understand how physical pressure influences fast-growing species traits. The resulting important modifications could imply a more functional impact such as biodiversity loss and carbon sequestration, which is beyond the scope of the present paper. %B Estuarine, Coastal and Shelf Science %V 235 %P 106581 %G eng %U http://www.sciencedirect.com/science/article/pii/S027277141930068X %R https://doi.org/10.1016/j.ecss.2020.106581 %0 Journal Article %J Science of The Total Environment %D 2020 %T Towards transferability in fish migration models: A generic operational tool for predicting silver eel migration in rivers %A Teichert, Nils %A Tétard, Stéphane %A Thomas Trancart %A de Oliveira, Eric %A Anthony Acou %A Alexandre Carpentier %A Bourillon, Bastien %A Eric Feunteun %K eel runs prediction %K ensemble modelling %K European eel management %K fish migration %K model transferability %K river obstacle %X In the global context of river fragmentation, predicting fish migration is urgent to implement management actions aimed at protecting and promoting the free movement of diadromous fish. However, large-scale applicability of conservation measures requires transferable models that enable prediction of migration even in data-poor regions. Here, we surveyed 12 contrasted European river sites to predict the activity peaks of silver eels (Anguilla anguilla) during river migration towards spawning areas through an ensemble modelling approach. Site-specific Boosted Regression Tree (BRT) models were adjusted using standardized hydrological variables to predict migration probability, which were aggregated in consensus predictions. Results of independent cross-validations demonstrated that silver eel migration runs were accurately predicted in response to changes in river discharge. Transferability and predictive performance were improved by considering catchment-size dissimilarity between river sites (85 to 109 930 km²) when combining the site-specific predictions. Nevertheless, we provided two examples for which the effects of human actions on flow conditions were so high that they prevented reliable predictions of migration runs. Further contributions should thus take advantage of the flexibility of our approach for updating model collection with new sites to extend the predictive performance under a larger range of ecological conditions. Our transferable hydrological-based modelling framework offers an opportunity to implement large-scale management strategies for eel conservation, even in rivers where eel monitoring data lack. The BRT models and prediction functions were compiled in an R package named ‘silvRpeak’ to facilitate operational implementation by end-user managers, which can determine when mitigation measures should be implemented to improve river continuity (e.g. turbine shutdown and sluice gate opening) and balance their economic activity towards eel conservation. The only input required is discharge records that are widely available across European hydrological stations. %B Science of The Total Environment %V 739 %P 140069 %8 Jan-10-2020 %G eng %U https://linkinghub.elsevier.com/retrieve/pii/S0048969720335890 %!

The drastic decline in European eel Anguilla anguilla stock is now widely recognized. However, while various causes for this decline have been identified, the relative importance of each cause remains unclear.

2. During the catadromous migration of silver eels, the negative impact of dams is frequently highlighted, but mainly for powered dams (with turbines) or where connectivity is completely ruptured. Mechanical impact due to turbine blades is often considered the most important cause of mortality of silver eels during downstream migration. Consequently, non-powered dams equipped with spillways are often considered safe for the passage of migrating silver eels.

3. We hypothesized that, to understand the negative impacts of dams, a much wider context must be considered than turbine mortality alone. Using an acoustic telemetry survey of silver eels, we demonstrated the negative effects of non-powered dams on downstream migration.

4. Five main impacts on eel populations were highlighted: (i) the attenuation or loss of triggering factors, leading to an absence of or delay in migration; (ii) extra delays and extra distances travelled when crossing the dam; (iii) extra energetic costs of the additional distance travelled as result of exploring the dam and the reservoir to find other escape passages; (iv) the selection of a more risky behavioral phenotype, i.e., bold eels; and (v) direct blocking once migration has started. Mortality was evaluated as a supplementary impact. Some of these effects (attenuation of triggers, extra delays to cross the dam) might be more important than the same effect from powered dams, probably due to the constant high water discharge required for turbines that facilitate the passage of eels.

5. As these “safe” dams are very widespread, they must be considered a potential threat to effective eel conservation. %B Ecological Engineering %V 145 %P 105741 %G eng %U http://www.sciencedirect.com/science/article/pii/S092585742030029X %R https://doi.org/10.1016/j.ecoleng.2020.105741 %0 Journal Article %J Ecology of Freshwater Fish %D 2019 %T Behaviour of endangered European eels in proximity to a dam during downstream migration: Novel insights using high accuracy 3D acoustic telemetry %A Thomas Trancart %A Alexandre Carpentier %A Anthony Acou %A Danet, Valentin %A Elliott, Sophie %A Eric Feunteun %K 3D acoustic telemetry %K dam %K diadromous fish %K downstream migration %K European eel %X River infrastructures such as weirs, hydropower stations or water reservoirs represent obstructions to migration for diadromous fish. Knowledge of accurate behaviour of fish in front of such structures is required to protect migrants from hazardous areas, guide them towards safe passage or adapt structure to improve the escapement. We developed and made available a method to process acoustic telemetry data based on Time Difference Of Arrival analysis to accurately locate tagged fish. Improved accuracy allows the detection of escape routes and description of dam-crossing tactics. Sixteen tagged eels were tracked with high accuracy (1–2 m) and 1 location min−1 frequency during their exploration period on reaching the dam. Two migration routes (spillways and bottom compensation flow pipe) were used by 77% and 23% of eels respectively. Spillways were the preferred route, but a median of 16 days were required to pass the dam versus 1.1 days via the compensation pipe. A minimal water crest of 40 cm was required for passage via spillways. Eels passing through the compensation pipe were exclusively nocturnal and mainly explored the bottom of the dam. Eels passing through spillways explored the whole dam area by night and day, and were not attracted to the compensation pipe entrance. With global warming, more frequent drought periods are expected, potentially leading to decreased opportunities for eels to migrate across safer dams by spillways. To conserve this endangered species, dam management strategies that account for expected hydrologic conditions and distinct exploration behaviours are needed. %B Ecology of Freshwater Fish %V 29 %P 266-279 %G eng %U https://onlinelibrary.wiley.com/doi/abs/10.1111/eff.12512 %R 10.1111/eff.12512 %0 Journal Article %J Ecological Indicators %D 2019 %T Changes in marine phytoplankton diversity: Assessment under the Marine Strategy Framework Directive %A Rombouts, I. %A Nathalie Simon %A Anais Aubert %A T.

In this pilot study, we used three coastal time-series in the Western Channel and the north of the Bay of Biscay (North Atlantic, France) to test the efficiency and the performance of several existing diversity indices. We validated two alpha diversity indices, namely the Menhinick Index (D) and the Hulburt Index (δ), based on their complementary ecological information, their strong relationship with habitat characteristics, and their relative ease of interpretation for stakeholders. Temporal shifts or rate of change in community structure were detected by the Local Contributions to Beta Diversity index (LCBD; a beta diversity measure). For the years where significantly high LCBD values were found, the Importance Value Index (IVI) was calculated to potentially identify the taxa (genus) responsible for the “unusual” community structure. For example, at the Ouest Loscolo site in 2008, an elevated LCBD (0.45) coincided with a high dominance value (Hulburt’s Index) caused by the occurrence of a monospecific bloom of Leptocylindrus spp. (IVI = 73%) in July (2.22 × 106 cells L−1) and October (8 × 106 cells L−1). In this way, PH3 informs on different aspects of phytoplankton diversity from a community to a genus level. At the current stage of development, however, PH3 acts as a “surveillance” rather than an operational indicator since the relationship to GES is not directly tracked. In the future, by additional testing of PH3 and extending the geographical scope, the robustness of the assessment could be further determined across the OSPAR Maritime Area. %B Ecological Indicators %V 102 %P 265 - 277 %G eng %U http://www.sciencedirect.com/science/article/pii/S1470160X19301190 %R https://doi.org/10.1016/j.ecolind.2019.02.009 %0 Journal Article %J Deep Sea Research Part II: Tropical Studies in Oceanography %D 2019 %T Contrasting biodiversity of eel larvae across the central Indian Ocean subtropical gyre %A Miller, Michael J %A Wouthuyzen, Sam %A Eric Feunteun %A Aoyama, Jun %A Watanabe, Shun %A Syahailatua, Augy %A Kuroki, Mari %A Robinet, Tony %A Hagihara, Seishi %A Otake, Tsuguo %A others %X The unique semi-enclosed Indian Ocean basin includes large Mascarene Plateau banks, offshore coral-reef islands, seasonal equatorial current jets, and cross-basin westward South Equatorial Current (SEC) flow, making it interesting for studying long larval-duration eel larvae (leptocephali) and regional eel biodiversity. Three surveys for leptocephali (in 2003, 2006, 2010) included sampling west of the Mascarene Plateau (west), a major survey and other stations off Sumatra and Java (east), and 2 cross-basin transects across the SEC. The highest numbers of leptocephali species were observed along Sumatra (2003: ~143 species; 2006: 72 species) and south of Java (2010: 69), with intermediate numbers being collected in the western Indian Ocean (2006: 71; 2010: 53) compared to low numbers in the hydrographically variable offshore zones (2006, 2010: 3–27). The larger continental shelf areas along Sumatra including the Mentawai Islands provide more coral reef and other habitats for species such as congrid, muraenid, ophichthid, and chlopsid eels compared to the Mascarene Plateau banks. Some larvae in these areas get transported offshore, but the majority of offshore larvae were of Nemichthyidae and Serrivomeridae mesopelagic eels that were spawning across the basin. Habitat differences between the southern Mascarene Plateau and Sumatra and southern Indonesia along the edge of the high biodiversity Coral Triangle likely explain the higher biodiversity of eel larvae observed along the western side of the basin, which for the Congridae and Ophichthidae included more species than observed previously within the central Indonesian Seas. In addition to local spawning, seasonal currents likely transport larger larvae towards Sumatra from the north or west and larvae may enter the basin from the Indonesian Throughflow in the east, but it is unknown if equatorial jets or the SEC can transport larvae across the whole basin. %B Deep Sea Research Part II: Tropical Studies in Oceanography %V 161 %P 120–131 %G eng %U https://www.sciencedirect.com/science/article/pii/S0967064517304393 %R doi.org/10.1016/j.dsr2.2018.02.012 %0 Journal Article %J Progress in Oceanography %D 2019 %T Distribution and life history trait models indicate vulnerability of skates %A Sophie A.M.

Specific management measures to improve the conservation of elasmobranchs can be problematic due to insufficient information on their biology and ecology. Here, three sympatric skates occupying north-eastern Atlantic waters, which have differing conservation status were studied within ICES divisions 4.c, 7.d–e, 7.f–h and 8a–b and d. Fisheries-dependent data on skate bycatch and a series of environmental variables were used to model spatio-temporal differences in habitat use between the three species. Raja undulata, the undulate ray (IUCN red listed as ‘Endangered’) was observed to have a coastal distribution within the English Channel and the Bay of Biscay (ICES division 7.d–e and 8.a–b). Raja clavata, the thornback ray (‘Near threatened’), had a broader distribution with higher presence in the eastern English Channel and the southern North Sea (ICES division 7.e and 4.c). Raja montagui, the spotted ray’s probability of presence (‘Least concerned’) was higher off the coast of southern Ireland (ICES division 7.g). Seasonal and life-history trait differences were also observed. From the fisheries-dependent data, wider skate distributions than previously studied were modelled. Although the species do co-occur, spatio-temporal differences between these species were observed. This study contributes to a greater understanding of skate habitat during their different life history stages, and indicates reasons for R. undulata’s increased vulnerability than R. clavata and R. montagui. Information from the distribution models could be used for specific spatio-temporal management measures. Better understanding of the distribution of species can also help reduce bycatch of protected species such as R. undulata. %B Progress in Oceanography %V 181 %P 102256 %G eng %U http://www.sciencedirect.com/science/article/pii/S0079661119304367 %R https://doi.org/10.1016/j.pocean.2019.102256 %0 Journal Article %J Progress in Oceanography %D 2019 %T Distribution of anguillid leptocephali and possible spawning areas in the South Pacific Ocean %A Mari Kuroki %A Michael J.

A July–October 2016 research cruise was conducted to study the spawning areas and times, and larval distributions of South Pacific anguillid eels, which included a short 155°E station-line northeast of New Guinea and five long transects (5–25°S, 160°E–140°W) crossing the South Equatorial (SEC) and other currents. This survey collected nearly 4000 anguilliform leptocephali at 179 stations using an Isaacs-Kidd Midwater Trawl accompanied by 104 CTD casts. Based on morphometric observations and DNA sequencing, 74 anguillid leptocephali were collected, which in the southern areas included 29 larvae of six species: Anguilla bicolor pacifica, A. marmorata, A. australis, A. reinhardtii, A. megastoma,and A. obscura (all anguillid species of the region were caught except A. dieffenbachii). Small A. australis (9.0–16.8 mm) and A. reinhardtii (12.4, 12.5 mm) leptocephali were collected south of the Solomon Islands, other A. australis (10.8–12.0 mm) larvae were caught northwest of Fiji along with an A. obscura (20.0 mm) larva, and an A. marmorata (7.8 mm) larva was collected near Samoa. Considering collection sites, larval ages from otolith analysis, and westward SEC drift, multiple spawning locations occurred from south of the Solomon Islands and the Fiji area (16–20 days old larvae) to near Samoa (19 days old larva) during June and July in areas where high-salinity Subtropical Underwater (STUW, 150 m depth) and the warm, low-salinity surface Fresh Pool were present. Five long hydrographic sections showed the strong Fresh Pool in the west and the STUW formation area in the east. %B Progress in Oceanography %V 180 %P 102234 %G eng %U http://www.sciencedirect.com/science/article/pii/S0079661119304148 %R https://doi.org/10.1016/j.pocean.2019.102234 %0 Book %B Oceanography Challenges to Future Earth: Human and Natural Impacts on our Seas %D 2019 %T The European eel (Anguilla anguilla) in France: An example of close cooperation among researchers and fishers to study and manage an endangered species %A Prouzet, P. %A Amilhat, E. %A Boisneau, C. %A Boisneau, P. %A Eric Feunteun %A Michelet, N. %B Oceanography Challenges to Future Earth: Human and Natural Impacts on our Seas %P 69-93 %G eng %U https://www.springerprofessional.de/en/the-european-eel-anguilla-anguilla-in-france-an-example-of-close/16484968 %R 10.1007/978-3-030-00138-4_7 %0 Journal Article %J Fisheries Management and Ecology %D 2019 %T High genetic diversity and lack of pronounced population structure in five species of sympatric Pacific eels %A Gubili, Chrysoula %A Robert Schabetsberger %A Poellabauer, Christine %A Bates, Becky %A Wagstaff, Rosa M. %A Woodward, Lewis M. %A Sichrowsky, Ursula %A Scheck, Alexander %A Boseto, David T. %A Eric Feunteun %A Anthony Acou %A Jehle, Robert %K genetic homogeneity %K hybridisation %K recruitment %K Spawning %K Sympatry %K tropical eels %X Understanding the population structure of tropical anguillids residing in the Pacific is vital for their conservation management. Here, the population genetic structure of five sympatric freshwater eels (Anguilla marmorata Quoy & Gaimard, A. megastoma Kaup, A. obscura Steindachner, A. reinhardtii Günther and A. australis Richardson) across 11 western South Pacific (WSP) islands was investigated based on partial nucleotide sequences of the mtDNA control region and the nuclear GTH2b genes of 288 newly collected samples jointly with existing sequences. WSP anguillids are characterised by overall high levels of genetic diversity. Both mtDNA and nuclear sequences provided no evidence for distinct geographic clines or barriers in any of the species across the WSP. The occurrence of admixed individuals between A. marmorata and A. megastoma was confirmed, and a new possible occurrence of a further species was revealed (A. interioris Whitley on Bougainville Island). All species showed evidence for demographic population growth in the Pleistocene, and a subsequent population reduction for A. megastoma. Common spawning grounds and mixing of larvae by ocean currents could promote the lack of pronounced isolation by distance, a finding that has significant implications for the future management of anguillids in the area. %B Fisheries Management and Ecology %V 26 %P 31-41 %G eng %U https://onlinelibrary.wiley.com/doi/abs/10.1111/fme.12287 %R 10.1111/fme.12287 %0 Journal Article %J Progress in Oceanography %D 2018 %T Dynamics of particulate organic matter composition in coastal systems: Forcing of spatio-temporal variability at multi-systems scale %A Liénart, Camilla %A Savoye, Nicolas %A David, Valérie %A Ramond, Pierre %A Rodriguez Tress, Paco %A Hanquiez, Vincent %A Marieu, Vincent %A Aubert, Fabien %A Aubin, Sébastien %A Bichon, Sabrina %A Boinet, Christophe %A Bourasseau, Line %A Bozec, Yann %A Bréret, Martine %A Elsa Breton %A Caparros, Jocelyne %A Cariou, Thierry %A Claquin, Pascal %A Conan, Pascal %A Corre, Anne-Marie %A Costes, Laurence %A Muriel Crouvoisier %A Del Amo, Yolanda %A Derriennic, Hervé %A Dindinaud, François %A Duran, Robert %A Durozier, Maïa %A Devesa, Jérémy %A Ferreira, Sophie %A Eric Feunteun %A Garcia, Nicole %A Geslin, Sandrine %A Emilie Grossteffan %A Gueux, Aurore %A Guillaudeau, Julien %A Guillou, Gaël %A Jolly, Orianne %A Lachaussée, Nicolas %A Lafont, Michel %A Lagadec, Véronique %A Lamoureux, Jézabel %A Lauga, Béatrice %A Lebreton, Benoît %A Lecuyer, Eric %A Lehodey, Jean-Paul %A Leroux, Cédric %A Stéphane L'Helguen %A Macé, Eric %A Maria, Eric %A Mousseau, Laure %A Antoine Nowaczyk %A Pineau, Philippe %A Petit, Franck %A Pujo-Pay, Mireille %A Raimbault, Patrick %A Rimmelin-Maury, Peggy %A Rouaud, Vanessa %A Sauriau, Pierre-Guy %A Sultan, Emmanuelle %A Susperregui, Nicolas %B Progress in Oceanography %V 162 %P 271 - 289 %8 Jan-03-2018 %G eng %U https://www.sciencedirect.com/science/article/abs/pii/S0079661117302100 %!

However, for the management of this endangered species, it is important to understand migration dynamics, and contribution to the breeding stock. This study aimed to assess the parameters that trigger and guide the migration of silver eels in the largest floodplain lake and associated wetlands in France (the sluice regulated Grand-Lieu Lake). A telemetry survey of 50 acoustic and PIT-tagged female silver eels was performed during the 2015–2016 migration period. We deployed a novel telemetric approach, using receivers to delimit several restricted virtual boxes to determine the instantaneous location of individuals and to transform simple discrete telemetric data into presence/absence data. The low numbers leaving the lake centre are probably explained by the lack of orienting water flows or other environmental clues, but whilst the fate of 34% (17/50) of the tagged eels is unknown, 18% (9/50) were caught by commercial fishermen. Modelling showed that detections were not clearly associated with environmental factors typically involved in riverine migrations (e.g. current velocity, atmospheric pressure and temperature) but they were particularly associated with higher and increasing water levels and, for eels exiting the lake, a sharp increase when sluice gates were opened to an effective gap of >75 cm. It is concluded that management of water levels and sluice gate opening during the migration period might aid escapement of silver eels. %B Ecology of Freshwater Fish %V 27 %P 570-579 %G eng %U https://onlinelibrary.wiley.com/doi/abs/10.1111/eff.12371 %R 10.1111/eff.12371 %0 Journal Article %J Conservation genetics %D 2018 %T Phylogeography of Eleotris fusca (Teleostei: Gobioidei: Eleotridae) in the Indo-Pacific area reveals a cryptic species in the Indian Ocean. %A Marion Mennesson %A Bonillo, Céline %A Eric Feunteun %A Philippe Keith %K Amphidromous %K Complete mitogenome %K freshwater fish %K Nuclear gene %X

 Indo-Pacific insular freshwater systems are mainly dominated by amphidromous species. Eleotris fusca  is a widespread one, its life cycle is characterised by a marine pelagic larval phase allowing the species to disperse in the ocean and then to recruit to remote island rivers. In the present study, the population structure of E. fusca  over its Indo-Pacific distribution range (Western Indian Ocean to French Polynesia, Pacific Ocean) was evaluated. We analysed a section of mitochondrial COI  of 557 individuals sampled from 28 islands to visualise the population structure. Haplotypes diversity (Hd) was between 0.458 and 1 and, nucleotide diversity (π) was between 0.001 and 0.02. Two distinct genetic groups appeared, one in the Indian Ocean and the other in the Pacific Ocean (FST  mean = 0.901; 5.2% average divergence). Given these results, complete mitogenomes (mtDNA) were sequenced and combined with the nuclear Rhodopsin (Rh) gene for a subset of individuals. The two phylogenetic trees based on each analysis showed the same genetic pattern: two different groups belonging to the Indian and the Pacific oceans (6.6 and 1.6% of divergence for mtDNA and Rh gene respectively), which supported species level differentiation. These analyses revealed the presence of two sister species confounded until present under the name of Eleotris fusca. One of them is cryptic and endemic of the Indian Ocean and the other one is the true E. fusca, which keeps, nevertheless, its status of widespread species.

Very different effects on migration success can result from this choice, such as speed and migration duration or escapement rate. We studied the downstream migration of silver eels in a river section with two different routes. The first route is the initial and old riverbed, with two dams equipped with two rather small or medium sized hydropower plants (HPPs) located at the beginning and at the exit of the bypass stretch. Both HPPs have small bar spacing (10 mm and 20 mm, respectively) and the second HPP has two downstream bypasses. The second route is a power canal, supplying four major HPPs (maximum discharge capacity = 1400 m3 s−1) and a nuclear power plant with cooling water. Firstly, this study focused on highlighting the factors influencing route choice. Secondly, we focused on the consequences of this choice. We demonstrate that water current management in the old riverbed at the study site had a 40% higher negative effect on eel survival than that by a consecutive passage in four turbines. %B Ecological Engineering %V 123 %P 202 - 211 %G eng %U http://www.sciencedirect.com/science/article/pii/S0925857418303318 %R https://doi.org/10.1016/j.ecoleng.2018.09.002 %0 Journal Article %J Journal of Experimental Marine Biology and Ecology %D 2018 %T Stable isotopes as tracers can reveal resource allocation in juvenile golden gray mullets (Liza aurata, Risso, 1810) %A Como, S. %A Alexandre Carpentier %A Rossi, F. %A Christine Dupuy %A Richard, P. %A Eric Feunteun %A Lefrançois, C. %X Studies on the nutritional physiology of predator fish in the marine environment have contributed to our understanding of how they adapt to the environment and how they have evolved. Despite the fact that herbivorous and omnivorous fish species are numerous and play a significant role in the ecosystem, there is little information on how they process nutrients and how these are allocated to different tissues. This information could be particularly important for the juvenile stages, when small-sized fish are under high predation pressure and have a limited capability to intake and digest large quantities of food. The mullet Liza aurata ingests surface sediment and obtains its nutritional requirements from the organisms associated with the sediment, including microalgae and bacteria or small invertebrates. This paper examines how the carbon and nitrogen derived from benthic micro-organisms are allocated to the liver and muscle tissues of newborn (young-of-the-year, YOY) and one-year-old (OYO) individuals. After the animals were left feeding on 13C-enriched microalgae and 15N-enriched bacteria for 1 h, we traced the 13C and 15N in the liver and muscle tissues as well as in the blood and the gut. The YOY allocated 99% of the 13C and 88% of the 15N to the muscles, while the liver had a negligible amount of tracers (0.4% and 11% for 13C and 15N). Conversely, in the OYO experiment, the tracers were uniformly distributed throughout the muscle and liver (57% of 13C and 45% of 15N were found in the muscle, whereas 43% of 13C and 55% of 15N were in the liver). Negligible amounts were traced in the blood (<0.1%), while a part of the tracers was not assimilated and remained in the gut of both YOY and OYO fish. These results indicated a size-related shift in resource allocation during first year of growth of L. aurata, probably related to changes in the survival strategies among juveniles. Our results also indicated that stable isotope enrichment can be a helpful tool for studying resource allocation in fish. %B Journal of Experimental Marine Biology and Ecology %V 503 %P 72 - 79 %8 Jan-06-2018 %G eng %U https://www.sciencedirect.com/science/article/pii/S0022098117301971 %!

In this study, we seek to provide an evaluation procedure by (1) investigating the distribution of rarity among subtidal rock bottom phyla; (2) searching for potential surrogate phyla with a cross-taxon congruence approach based on their rarity; (3) proposing an appropriate multi-phyla indicator to evaluate the importance of subtidal rocky habitats for conservation. We analysed the distribution of 548 species belonging to 8 phyla sampled in 137 assemblages in subtidal rocky areas located around Brittany, Western France. We applied the Index of Relative Rarity, a flexible method which fits rarity weights to species depending on their respective phyla. We found only weak congruence in rarity patterns among phyla, which prevented any attempt to identify surrogate phyla. This finding has important implications for the conservation of subtidal rocky habitats as it means that there is no shortcut to monitor their rarity: working on a subset of phyla would imply a biased evaluation of biodiversity. Consequently, we propose a multi-phyla Index of Relative Rarity combining all phyla which allowed us to successfully describe rarity patterns across all sampled sites. %B Ecological Indicators %V 77 %P 239–249 %G eng %U http://dx.doi.org/10.1016/j.ecolind.2017.02.012 %R 10.1016/j.ecolind.2017.02.012 %0 Journal Article %J Progress in Oceanography %D 2017 %T Dynamics of particulate organic matter composition in coastal systems: A spatio-temporal study at multi-systems scale %A Liénart, Camilla %A Savoye, Nicolas %A Bozec, Yann %A Elsa Breton %A Conan, Pascal %A David, Valérie %A Eric Feunteun %A Karine Grangeré %A Kerhervé, P. %A Lebreton, B. %A Sébastien Lefebvre %A Stéphane L'Helguen %A Mousseau, Laure %A Raimbault, P %A Richard, P. %A Riera, P. %A Sauriau, P.-G. %A Gauthier Schaal %A Aubert, F. %A Aubin, S. %A Bichon, S. %A Boinet, C. %A Bourasseau, L. %A Bréret, M. %A Caparros, J. %A Cariou, T. %A Charlier, K. %A Claquin, P. %A Vincent Cornille %A Corre, A.-M. %A Costes, L. %A Crispi, O. %A Muriel Crouvoisier %A Czamanski, M. %A Del Amo, Y. %A Derriennic, H. %A Dindinaud, F. %A Durozier, M. %A Hanquiez, V. %A Antoine Nowaczyk %A Devesa, J. %A Ferreira, S. %A Fornier, M. %A Garcia, F. %A Garcia, N. %A Geslin, S. %A Emilie Grossteffan %A Gueux, A. %A Guillaudeau, J. %A Guillou, G. %A Joly, O. %A Lachaussée, N. %A Lafont, M. %A Lamoureux, J. %A Lecuyer, E. %A Lehodey, J.-P. %A Lemeille, D. %A Leroux, C. %A Macé, E. %A Maria, E. %A Pineau, P. %A Petit, F. %A Pujo-Pay, M. %A Rimelin-Maury, P. %A Sultan, E. %K bacterium %K benthos %K biogeochemistry %K Biological materials %K C and n stable isotopes %K C:N ratio %K Carbon %K carbon isotope %K Coastal systems %K coastal zone %K Fluid dynamics %K France %K geomorphology %K Hydrodynamics %K Isotopes %K isotopic ratio %K Mediterranean sea %K Meta analysis %K meta-analysis %K Mixing %K Mixing models %K nitrogen isotope %K Organic compounds %K particulate organic matter %K Particulate organic matters %K Phytoplankton %K prokaryote %K Rivers %K seasonality %K spatiotemporal analysis %K stable isotope %K Surface water %K Surface waters %K terrestrial deposit %K Time series %X In coastal systems, the multiplicity of sources fueling the pool of particulate organic matter (POM) leads to divergent estimations of POM composition. Eleven systems (two littoral systems, eight embayments and semi-enclosed systems and one estuary) distributed along the three maritime façades of France were studied for two to eight years in order to quantify the relative contribution of organic matter sources to the surface-water POM pool in coastal systems. This study was based on carbon and nitrogen elemental and isotopic ratios, used for running mixing models. The POM of the estuary is dominated by terrestrial material (93% on average), whereas the POM of the other systems is dominated by phytoplankton (84% on average). Nevertheless, for the latter systems, the POM composition varies in space, with (1) systems where POM is highly composed of phytoplankton (≥93%), (2) systems characterized by a non-negligible contribution of benthic (8–19%) and/or river (7–19%) POM sources, and (3) the Mediterranean systems characterized by the contribution of diazotroph organisms (ca. 14%). A continent-to-ocean gradient of river and/or benthic POM contribution is observed. Finally, time series reveal (1) seasonal variations of POM composition, (2) differences in seasonality between systems, and (3) an inshore-offshore gradient of seasonality within each system that were sampled at several stations. Spatial and seasonal patterns of POM composition are mainly due to local to regional processes such as hydrodynamics and sedimentary hydrodynamic (e.g. resuspension processes, changes in river flows, wind patterns influencing along-shore currents) but also due to the geomorphology of the systems (depth of the water column, distance to the shore). Future studies investigating the link between these forcings and POM composition would help to better understand the dynamics of POM composition in coastal systems. © 2017 Elsevier Ltd %B Progress in Oceanography %V 156 %P 221-239 %G eng %U https://www.sciencedirect.com/science/article/abs/pii/S0079661116301914 %R 10.1016/j.pocean.2017.03.001 %0 Journal Article %J Parasitology Research %D 2017 %T Metazoan parasite communities in Alosa alosa (Linnaeus, 1758) and Alosa fallax (Lacépède, 1803) (Clupeidae) from North-East Atlantic coastal waters and connected rivers %A Gérard, C. %A Hervé, M. %A Gay, M. %A Bourgau, O. %A Eric Feunteun %A Anthony Acou %A Réveillac, E. %B Parasitology Research %V 116 %P 2211-2230 %G eng %U https://link.springer.com/article/10.1007%2Fs00436-017-5525-8 %R 10.1007/s00436-017-5525-8 %0 Journal Article %J Progress in Oceanography %D 2017 %T Trophic position increases with thermocline depth in yellowfin and bigeye tuna across the Western and Central Pacific Ocean %A Houssard, P. %A Lorrain, A. %A Tremblay-Boyer, L. %A Allain, V. %A Graham, B.S. %A Menkes, C.E. %A Pethybridge, H. %A Couturier, L.I.E. %A Point, D. %A Leroy, Bruno %A Receveur, A. %A Hunt, B.P.V. %A Vourey, E. %A Bonnet, S. %A Rodier, M. %A Raimbault, P. %A Eric Feunteun %A Kuhnert, P.M. %A Munaron, J.-M. %A Lebreton, B. %A Otake, T. %A Letourneur, Y. %B Progress in Oceanography %V 154 %P 49-63 %G eng %U https://www.sciencedirect.com/science/article/pii/S007966111630177X %R 10.1016/j.pocean.2017.04.008 %0 Journal Article %J Ecology of Freshwater Fish %D 2016 %T Difference in factors explaining growth rate variability in European eel subpopulations: The possible role of habitat carrying capacity %A Boulenger, C. %A Crivelli, A.J. %A Charrier, F. %A Roussel, J.-M. %A Eric Feunteun %A Anthony Acou %B Ecology of Freshwater Fish %V 25 %P 281-294 %G eng %U https://onlinelibrary.wiley.com/doi/abs/10.1111/eff.12209 %R 10.1111/eff.12209 %0 Journal Article %J Estuarine, Coastal and Shelf Science %D 2016 %T Difference in responses of two coastal species to fluctuating salinities and temperatures: Potential modification of specific distribution areas in the context of global change %A Thomas Trancart %A Eric Feunteun %A Lefrançois, C. %A Anthony Acou %A Boinet, C. %A Alexandre Carpentier %B Estuarine, Coastal and Shelf Science %V 173 %P 9-15 %G eng %U https://www.sciencedirect.com/science/article/pii/S0272771416300555 %R 10.1016/j.ecss.2016.02.012 %0 Journal Article %J Cryptogamie, Algologie %D 2016 %T Dinard Herbarium: History of a Marine Station1 %A Lamy, Dominique %A Robuchon, Marine %A Kervran, L. %A Dennetiere, B. %A Eric Feunteun %A Le Gall, L. %B Cryptogamie, Algologie %V 37 %P 29-45 %G eng %U https://bioone.org/journals/Cryptogamie-Algologie/volume-37/issue-1/v37.iss1.2016.29/Dinard-Herbarium-History-of-a-Marine-Station1/10.7872/crya/v37.iss1.2016.29.short %R 10.7872/crya/v37.iss1.2016.29 %0 Journal Article %J Environmental Biology of Fishes %D 2016 %T Disrupted downstream migration behaviour of European silver eels (Anguilla anguilla, L.) in an obstructed river %A Besson, M.L. %A Thomas Trancart %A Anthony Acou %A Charrier, F. %A Mazel, V. %A Legault, A. %A Eric Feunteun %B Environmental Biology of Fishes %V 99 %P 779-791 %G eng %U https://link.springer.com/article/10.1007/s10641-016-0522-9 %R 10.1007/s10641-016-0522-9 %0 Journal Article %J Science Advances %D 2016 %T Empirical observations of the spawning migration of European eels: The long and dangerous road to the Sargasso Sea. %A D.

Walker %A Thomas Trancart %A U Brämick %A K. Aarestrup %X The spawning migration of the European eel (Anguilla anguilla L.) to the Sargasso Sea is one of the greatest animal migrations. However, the duration and route of the migration remain uncertain. Using fishery data from 20 rivers across Europe, we show that most eels begin their oceanic migration between August and December. We used electronic tagging techniques to map the oceanic migration from eels released from four regions in Europe. Of 707 eels tagged, we received 206 data sets. Many migrations ended soon after release because of predation events, but we were able to reconstruct in detail the migration routes of >80 eels. The route extended from western mainland Europe to the Azores region, more than 5000 km toward the Sargasso Sea. All eels exhibited diel vertical migrations, moving from deeper water during the day into shallower water at night. The range of migration speeds was 3 to 47 km day−1. Using data from larval surveys in the Sargasso Sea, we show that spawning likely begins in December and peaks in February. Synthesizing these results, we show that the timing of autumn escapement and the rate of migration are inconsistent with the century-long held assumption that eels spawn as a single reproductive cohort in the springtime following their escapement. Instead, we suggest that European eels adopt a mixed migratory strategy, with some individuals able to achieve a rapid migration, whereas others arrive only in time for the following spawning season. Our results have consequences for eel management. %B Science Advances %G eng %U https://advances.sciencemag.org/content/2/10/e1501694 %R 10.1126/sciadv.1501694 %0 Journal Article %J Freshwater Biology %D 2016 %T Factors determining survival of European eels in two unexploited sub-populations %A Boulenger, C. %A Anthony Acou %A Gimenez, O. %A Charrier, F. %A Tremblay, J. %A Eric Feunteun %B Freshwater Biology %V 61 %P 947-962 %G eng %U https://onlinelibrary.wiley.com/doi/abs/10.1111/fwb.12759 %R 10.1111/fwb.12759 %0 Journal Article %J Marine Ecology and Progress Series %D 2016 %T Geographic variation in stable isotopic and fatty acid composition of anguilliform leptocephali and particulate organic matter in the South Pacific %A Liénart, Camilla %A Eric Feunteun %A Miller, M J %A Aoyama, J %A Jean-Michel Mortillaro %A Cédric Hubas %A Kuroki, M %A Watanabe, S %A Christine Dupuy %A Alexandre Carpentier %A Otake, T %A Tsukamoto, K %A Tarik Meziane %K Leptocephali · Fatty acids · Stable isotopes · Biomarkers · Trophic ecology · Oceanic currents %X

The feeding ecology of leptocephali has remained poorly understood because they apparently feed on particulate organic matter (POM), which varies in composition, and it is unclear which components of the POM they assimilate. The δ13C and δ15N stable isotope (SI) and fatty acid (FA) compositions of 3 families of leptocephali and POM were compared in 3 latitudinal current zones of the western South Pacific. The δ15N signatures of leptocephali and POM overlapped, with both having their lowest values in the southern current zone. POM in general (across all zones) contained 38 FAs and was rich in saturated FAs (SFA) (16:0, 18:0, 14:0), while leptocephali contained 50 FAs, with high proportions of 16:0, and higher contributions of 22:6ω3, 20:5ω3, 18:1ω9, 16:1ω7 and other FAs than found in the POM. Serrivomeridae leptocephali in the north had higher δ15N signatures and were also distinguished from Nemichthyidae and Muraenidae larvae by their FA compositions (higher SFAs, lower 22:6ω3 and 20:5ω3). Although SI signatures of the Serrivomeridae larvae did not clearly vary with size, 16:0 and 18:0 FA proportions decreased with increasing larval size, and 22:6ω3 and 16:1ω7 increased in larger larvae. Correspondences between the latitudinal variations in nitrogen SI signatures and FA compositions of POM with those of leptocephali and the presence of FA markers of both autotrophic and heterotrophic organisms were consistent with leptocephali feeding on POM. POM can contain various materials from primary producers and heterotrophic microorganisms, but differences in the SI signatures and FA compositions in leptocephali remain to be explained through further research.
