Behavioural Ecology and Biology of Fish Populations (ECOBIOP)

The Behavioural Ecology and Biology of Fish Populations Joint Research Unit (ECOBIOP) produces both fundamental and applied knowledge to foster sustainable management of wild fish populations.

Missions and objectives

The research focuses on diadromous fishes (salmon, trout, eel, shad, etc.). These highly migratory species live alternately in freshwater and at sea and are remarkable biodiversity components. They have long been exploited by human communities and providing ecosystem services. Due to their special ecological features, they are highly sensitive to anthropogenic activities. ECOBIOP research is particularly interested in the effects of climate change, fishing, stocking, damming and water contamination. By developping new knowledge and methods to tackle these issues, ECOBIOP aims at improving fish population management practices and at reconciling biodiversity conservation with human activities.

Scientific areas

The research undertaken by ECOBIOP covers behavioural and evolutionary ecology, combining disciplines as diverse as molecular biology, genetics, physiology, ethology, demography, and modelling. Integration across organization levels, ranging from the molecular (DNA) and cellular scales (metabolites) to population and metapopulation, is at the heart of ECOBIOP work. The individual level (behaviour, traits) is central and analysed considering both functional constraints (molecular determinism, energy budget) and social and evolutionary drivers. ECOBIOP combines experimental approaches (in controlled and semi-natural environments), long-term surveys in natural conditions, as well as virtual approaches through in silico simulations.

Outstanding projects

  • Member of I-SITE Energy & Environment Solutions (E2S, 2017-2020) led by the UPPA-INRA-INRIA consortium
  • Inra-French Agency for Biodiversity (AFB) framework agreement: various projects covering topics from sexual differentiation in eels to the management of salmon populations and genetics of migratory salmonid populations.
  • SALMOCLIM (Inra ACCAF metaprogramme): effects and adaptation of wild salmon to climate change.
  • FAUNA (Nouvelle-Aquitaine Region) and SHAD’EAU (Adour - Garonne Water Agency): ecology and conservation of shad populations.
