Overall activity 

Mixing genetics and physiology to obtain robust and efficient fish in various and fluctuating environments
Since 2016, we also work on the bee.

Outstanding results

  • Estimation of economic and environmental breeding values for selected traits
  • Genetic architecture of key traits for sustainable aquaculture: knowledge production and transfer to stakeholders.
  • Coordination of the European infrastructure project AQUAEXCEL2020

Scientific questions

1- Genetic architecture of efficiency traits

We focus on efficiency traits that will improve the economic pillar of sustainable development but also environmental and societal pillars.

- Feed efficiency
   Linked projects: H2020 Embric, PerformFish, AquaImpact.
- Disease resistance: genetic and functional bases of viral and bacterial disease resistance.
   Linked projects: H2020 Aqua-Faang ; FEAMP SG-Truite and Gènesea.
- Fatty acid profile in muscle
  Linked project: FEAMP OmegaTruite
- Resource allocations: interactions between efficiency traits and functional traits (health, immunity, stress response, behaviour, reproduction …). Theme being developed.

2- Physiology and genetics of responses to environmental and rearing stress

We combine physiological, behavioral, genetic and epigenetic approaches to study responses to different stressors.
- Adaptation to new diets, especially plant-based diets.  
   Linked projects: FUI Ninaqua, FEAMP AntiOb
- Adaptation to temperature, environment sensitivity and epigenetics, genetic variability of epigenetic marks.  
   Linked projects: H2020 AQUAEXCEL2020, FEAMP Epicool.
- Long-term consequences of early events: consequences, including transgenerational, of exposition to thermal stress or pollutants.  
  Linked projects: Sushifish, Ephemare, PlasticSeine
- Genetic and environmental determinism of sex: genetics of spontaneous maleness (trout), identification of neo-males with genomic predictions ; links sexual phenotype–expression/modification of candidate genes or epigenetic marks (seabass)
   Linked projects: FEAMP Neobio, 3S, ERANet Sushifish, H2020 AQUAEXCEL2020

3 – Management of selected populations:

- Genomic selection: interest and optimisation of genomic selection for different traits and different species (trout, seabass and seabream)
   Linked projects: FEAMP SG-Truite and GèneSea, two ‘CIFRE’ PhD
- Modelling of breeding programs for bees: setting up efficient breeding programs to improve production (royal jelly, honey), bee behavior and health.
   Linked project: Beestrong
- New technologies for reproduction: transplantation of stem cell and cryoconservation.
   Linked project : FEAMP Biogerm
We are also still developing genomic ressources.
