Team 2: Reproduction and development of aquatic organisms: evolution, adaptation, regulations

Eel genome project

2010 to 2016

The eel genome project has been founded by an international consortium (Netherlands, France, Japan, Norway).

The draft genomes of two eel species, the European eel, Anguilla anguilla, and the Japanese eel, Anguilla japonica, have been sequenced using the Illumina method.

The ongoing project includes further assembly of the European eel genome by using ew methodologies for direct sequencing and analysis of Megabase size DNA.

The consortium is also organising international conferences and workshops on eel genomics and transcriptomics.

Team 4: Larval dispersal and communities organization in austral and tropical island systems

Project Melanesia-Hotspot

2015 to 2017

The main objective of our project is to inventory in CEPF (Critical Ecosystem Partnership Fund) priority sites freshwater fish and crustaceans in Solomon and Vanuatu in order to fill the gaps identified at IUCN Redlisting workshop. It will propose management solutions that will assist environmental managers, land-owners, local communities and all those interested in sustainable freshwater management. This work will provide help:

Team 1: Evolution of Biomineralizations and Adaptations to Environmental Constraints

CaCHE

2013 to 2017

Anthropogenic driven climate change is an increasing global problem. Marine invertebrates, such as molluscs have been highlighted as being particularly at risk under future climate change scenarios due to the acidification and warming of the world’s oceans. It is predicted that their heavily calcified shells will become thinner as sea water becomes more acidic, not only changing their role as a CO2 sink but also profoundly impacting the ecological balance and biodiversity.

PRO-EEL

2010 to 2015

7th PCRD Programme "Food, Agriculture and Fisheries, and Biotechnology" KBBE-2009-1-2-13, n° 245257

The PRO-EEL project aims at breeding European eel (Anguilla anguilla) in captivity. Reproduction of eel in culture has become a focus research area due a severe decline of natural stocks and an increasing interest to breed eels for a self-sustained aquaculture. PRO-EEL is an international research project supported financially by the European Commission.

REPROSEED

2009 to 2014

The key objective of the REPROSEED project is to support the capacity of European hatcheries to respond to an increasing demand for mollusc seed. Hatchery seed production of Pacific oyster (Crassostrea gigas) is already well established, while for other species (Mytilus edulis, M. galloprovincialis, Ruditapes decussatus, Pecten maximus) it remains limited due to market or biological bottlenecks.

Team 3: Adaptations to Extreme Environments

MIDAS

2014 to 2016

The ecotoxicological risks posed by deep-sea mineral extraction are complex and poorly known. Heavy metals, trace metals and Rare Earth Elements (REEs) phases may be subject to considerable alteration in the marine environment during the mining and at-sea processing of minerals. MIDAS will focus on issues related to the mining of minerals, where there is an urgent demand for information.

The EcApRHA project

2015 to 2017

The EcApRHA project (Applying an Ecosystem Approach to (sub) Regional Habitat Assessment) co-financed by the EU DG Environment was a 15-month (December 2015 – February 2017) project, which focused on addressing gaps in the development of biodiversity (pelagic, benthic and food webs) indicators for the OSPAR Regions. In particular, the project aimed to overcome challenges in the development of indicators relating to the MSFD (Marine Strategy Framework Directive 56/2008/EU), such as Descriptor D1 (Biodiversity), D4 (Food webs) and D6 (Seafloor integrity).

PEGASEAS

2013 to 2014

PEGASEAS project aims to identify and capitalize on key lessons for sustainable governance of the marine ecosystem of the Channel area. The project is based on a cluster of projects: CAMIS, ChanneLIS, CHARM3, CRESH, Licco, MERiFIC, OFELIA, PANACHE, SETARMS, Marinexus and VALMER. The project aims to identify the key elements that have demonstrated better governance, synthesizing these elements consistent advice for practitioners and policy makers to share experiences, communicate to different audiences and provide input to the discussions

Pêcheries de Céphalopodes : outils pour gérer la ressource, préserver le recrutement et valoriser la production

2013 to 2015

English Channel Cephalopods (cuttlefish and squid) are among the most important resources of the Lower Normandy fishery. These stocks are not currently assessed regularly, which is necessary to define the conditions for sustainable exploitation. Among the inshore metiers, the trap fishery, although less destructive of the habitats than the trawling, knows the problem of the eggs fixed on the gear. The best possible value of these resources can also be obtained by optimizing their quality.

ATM LOCUS

2017 to 2018

Sex determination is a key physiological process of reproduction, essential to the life cycle. The Molluscs belong to the Lophotrochozoa, an important group of the Bilateria, poorly documented on this physiological mechanism.

This project aims to understand the sex determination in 2 Molluscs, the oyster Crassostrea gigas and the cuttlefish Sepia officinalis. These organisms are two species of economic importance, which exhibit very different life cycles and breeding patterns, reflecting the diversity of their phylum.

DEVO-LU puis LEDS

2016 to 2017

The objective of our project, taking place in two steps, is to test the role of the capsule of cuttlefish eggs in the light perception of the embryo. Actually, the influence of light on the development of aquatic organisms is not well known. Eggs of Sepia officinalis, laid in the tidal area, are protected from light by a black capsule. During the experimentation phase, three different photoperiods will be tested on two series of eggs, with and without capsule.

ATM SEPIOM

2015 to 2016

In cephalopod coleoid lineage, sepiids show an internal shell with two distinct parts: dorsal shield and phragmocone. Its mineral composition (aragonite) is well known but organic components, especially proteins, remain to be determined. We propose in this project to 1) identify the proteins  in organic fractions from dorsal shield and phragmocone 2) analyse gene expression of each part of shell sac (dorsal and ventral) and 3) determine if some identified components show similar enzymatic activities to those of other molluscs.
