2. Current topics

I am mainly interested in behavioural mechanisms underlying distribution patterns in young fish stages (with regard to migration, dispersal and habitat choice).

I work on diadromous species (salmonids, eel and shad) and try to identify the mechanisms involved at the individual level which could explain different strategies in use of space. This work is carried out in laboratory (using large flume, stream tanks, and circular flumes) natural or semi-natural conditions (using a 130 m long artificial channel and 8 stream tanks at the INRA Lapitxuri Field Station). These installations allow the observation of fish behaviour in an environment over which we have a complete control (indoor lab) or a partial one with a control of water flow, substratum and cover, fish community and sizes, or food supply. I try to develop an individual-based approach and to enlarge my field of interest towards other aspects such as physiology and indirect tools to investigate early life history patterns through collaborations. In addition, I develop a comparative approach on young stages use of space patterns in diadromous species.
