Loligo forbesii squid are thought to migrate inshore for breeding and offshore for feeding and long-range movements are implied from past studies showing genetic homogeneity in the entire neritic population.

The present study applied mitchondrial and microsatellite markers (nine loci) to samples from Rockall Bank, north Scotland, North Sea, various shelf locations in Ireland, English Channel, northern Bay of Biscay, north Spain, and Bay of Cadiz. No statistically significant genetic sub-structure was found, although some non-significant trends involving Rockall were seen using microsatellite markers. Differences in L. forbesii statolith shape were apparent at a subset of locations, with most locations showing pairwise differences and statoliths from north Ireland being highly distinct. This suggests that (i) statolith shape is highly sensitive to local conditions and (ii) L. forbesii forms distinguishable groups (based on shape statistics), maintaining these groups over sufficiently long periods for local conditions to affect the shape of the statolith. Overall evidence suggests that L. forbesii forms separable (ecological) groups over short timescales with a semi-isolated breeding group at Rockall whose distinctiveness varies over time.}, issn = {1054-3139}, doi = {10.1093/icesjms/fsac039}, url = {https://doi.org/10.1093/icesjms/fsac039}, author = {Sheerin, Edel and Barnwall, Leigh and Abad, Esther and Larivain, Angela and Oesterwind, Daniel and Petroni, Michael and Perales-Raya, Catalina and Jean-Paul Robin and Sobrino, Ignacio and Valeiras, Julio and O{\textquoteright}Meara, Denise and Pierce, Graham J and Allcock, A Louise and Power, Anne Marie} } @article {8681, title = {Phylogeography of the veined squid, Loligo forbesii, in European watersAbstract}, journal = {Scientific Reports}, volume = {12}, year = {2022}, month = {Jan-12-2022}, doi = {10.1038/s41598-022-11530-z}, url = {https://www.nature.com/articles/s41598-022-11530-z}, author = {G{\"o}pel, Anika and Oesterwind, Daniel and Barrett, Christopher and Cannas, Rita and Caparro, Luis Silva and Carbonara, Pierluigi and Donnaloia, Marilena and Follesa, Maria Cristina and Larivain, Angela and Laptikhovsky, Vladimir and Lefkaditou, Evgenia and Jean-Paul Robin and Santos, Maria Bego{\~n}a and Sobrino, Ignacio and Valeiras, Julio and Valls, Maria and Vieira, Hugo C. and Wieland, Kai and Bastrop, Ralf} } @article {7987, title = {Identification of benthic egg masses and spawning grounds in commercial squid in the English Channel and Celtic Sea: Loligo vulgaris vs L. forbesii}, journal = {Fisheries Research}, volume = {241}, year = {2021}, month = {Jan-09-2021}, pages = {106004}, issn = {01657836}, doi = {10.1016/j.fishres.2021.106004}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0165783621001326}, author = {Laptikhovsky, Vladimir and Cooke, Gavan and Barrett, Christopher and Lozach, Sophie and MacLeod, Eleanor and Oesterwind, Daniel and Sheerin, Edel and Petroni, Michael and Barnwall, Leigh and Jean-Paul Robin and Allcock, Louise and Power, Anne Marie} } @article {7189, title = {Establishment and population features of the non-native Atlantic rangia, Rangia cuneata (Mollusca: Bivalvia), in northwestern France}, volume = {15}, year = {2020}, pages = {367-381}, abstract = {The presence of shells of the Atlantic rangia, Rangia cuneata, a brackish-water species native from the Gulf of Mexico also known as gulf wedge clam, was reported in 2017 on the French coasts of the English Channel, in the waterway that connects Caen to the sea.

An experimental rearing was performed over 35\ days after hatching (DAH) on juveniles from wild collected eggs in 2010 and 2011. Four digestive enzyme activities and their ratios [i.e., trypsin, cathepsin, acid (ACP), and alkaline (ALP) phosphatase, ALP/ACP, and trypsin/cathepsin] were studied along with histological features (e.g., internal yolk surface and digestive gland development). The two enzyme ratios were good indicators of digestive system maturation allowing the study of the digestive gland{\textquoteright}s development. They were highly correlated to juveniles{\textquoteright} weight increase and histological features of the gland in early DAH. These ratios described more accurately the shift occurring between the intracellular acid and the extracellular alkaline modes of digestion in S. officinalis and were more specific than separated enzyme activities. Their application as eco-physiological tools revealed that enzyme ratios reflected yolk content and digestive gland development in new hatching juveniles. Finally, ALP/ACP ratio was shown to be a powerful tool to describe growth performance of S. officinalis which is useful for aquaculture optimization. {\textcopyright} 2017, Springer-Verlag GmbH Germany.}, keywords = {Acid Phosphatase, alkaline phosphatase, anatomy and histology, animal, Animals, Aquaculture, cathepsin, Cathepsins, cuttlefish, Gastrointestinal Tract, Physiology, Sepia, Trypsin}, issn = {01741578}, doi = {10.1007/s00360-017-1115-4}, url = {https://link.springer.com/article/10.1007\%2Fs00360-017-1115-4}, author = {Safi, Georges and Anne-Sophie Martinez and Le Pabic, Charles and Estelle Le Bihan and Jean-Paul Robin and Koueta, Noussith{\'e}} } @article {6666, title = {A Bayesian two-stage biomass model for stock assessment of data-limited species: An application to cuttlefish (Sepia officinalis) in the English Channel}, journal = {Fisheries Research}, volume = {191}, year = {2017}, pages = {131-143}, abstract = {Cuttlefish is a key commercial species in the English Channel fishery in terms of landings and value. Age-based assessment methods are limited by time-consuming age determination with statoliths and the lack of stock assessment models tailored to this data-limited species. A two-stage biomass model is developed in the Bayesian state-space modelling framework that allows inferences to be made on the stock biomass at the start, middle and end of each fishing seasons between 1992 and 2014, while accounting for both process and measurement errors and to assimilate various sources of information. A method that uses ancillary length-frequency data is developed to provide an informative prior distribution for the biomass growth rate parameter g (E\ =\ 0.89) and its annual variability (CV\ =\ 0.1). The new model is a substantial improvement on the existing stock assessment method used by the International Council for the Exploration of the Seas. Taking into consideration a time-varying g parameter provides a more ecologically meaningful model with regard to the sensitivity of the cuttlefish population dynamics to environmental fluctuations and improves model fit. The model also provides predictions of the unexploited biomass in winter, which is based on survey data, and helps manage the stock in the event of strong depletion. {\textcopyright} 2017 Elsevier B.V.}, issn = {01657836}, doi = {10.1016/j.fishres.2017.03.010}, url = {http://www.sciencedirect.com/science/article/pii/S0165783617300772}, author = {Juliette Alemany and Etienne Rivot and Foucher, Eric and Jo{\"e}l Vigneau and Jean-Paul Robin} } @article {4041, title = {The Channel ecosystem, a cross-roads of anthropogenic pressures and scientific studies: Lessons learned from the European \{INTERREG\} \{IV\} projects (2009{\textendash}2015)}, journal = {Marine Policy}, volume = {63}, year = {2016}, month = {11/2015}, pages = {158 - 165}, author = {L Evariste and Pascal Claquin and Jean-Paul Robin and Arnaud Auber and Abigail McQuatters-Gollop and Jean-Claude Dauvin} } @article {3764, title = {The role of female cephalopod researchers: past and present}, journal = {Journal of Natural History}, volume = {49}, year = {2015}, pages = {1235{\textendash}1266}, issn = {0022-2933}, doi = {10.1080/00222933.2015.1037088}, url = {http://dx.doi.org/10.1080/00222933.2015.1037088}, author = {Allcock, A.

Within the English Channel, the common cuttlefish Sepia officinalis is a semelparous species for which a 2-year life cycle was
exclusively described in the 1980s. In the 1990s, new research indicated that whilst a 2-year life cycle was still evident for
females and the large majority of males, a small proportion of males were actually maturing at only 1 year of age. Since
1980, the interest of French and UK fishers for this resource has increased and it is nowadays one of the most important
demersal species of the area and is considered to be fully exploited. From the start of the 20th century, fishing effort
and sea surface temperatures have increased in the English Channel and have probably impacted the life history traits of
S. officinalis. A 2-year sampling programme was undertaken at French landing sites of the English Channel during the reproduction
season in 2010 and 2011 to estimate if the proportion of 1-year-old mature animals has changed. Age determination
was carried out by coupling polymodal decomposition and lipofuscin measurement. Size-at-maturity for each year and each
sex was estimated by fitting a binomial error GLM. Results highlight that a variable percentage of males and females belonging
to the first cohort are mature and that size-at-maturity was lower than that observed in the 1990s. Finally, different parameters,
such as temperature and fishing pressure are explored to discuss changes in life history traits suggesting that cuttlefish
could be an indicator of the temperature regime shift in the English Channel.

As one of the busiest marine ecosystems in the world, the English Channel is subjected to strong pressures due to the human activities occurring within it. Effective governance is required to improve the combined management of different activities and so secure the benefits provided by the Channel ecosystem. In July 2014, a Cross-Channel Forum, entitled "Science and Governance of the Channel Marine Ecosystem", was held in Caen (France) as part of the INTERREG project "Promoting Effective Governance of the Channel Ecosystem" (PEGASEAS). Here we use outputs from the Forum as a framework for providing Channel-specific advice and recommendations on marine governance themes, including the identification of knowledge gaps, which may form the foundation of future projects for the next INTERREG project call (2015-2020).
