Setting of an experimental device for behavioural study of young stages of fish: description of behaviour and substrate choice of the biological model Acipenser baerii
This work aims to develop a tool which makes it possible to approach the conditions met in the natural environment for the autoecologic study of the young stages of fish. This study was carried out with a biological model Acipenser baerii, because of disponibility and practical reasons. The experime...
