Identification des zones d’habitats essentiels et estimation de la mortalité naturelle des juvéniles de bar en nourriceries |
|
Land-sea interfaces play a crucial role for many harvested marine species, as this is where juveniles grow. These nursery areas are naturally highly variable, but are also subject to significant anthropogenic pressures (pollution, shoreline development plans, dredging) that can lead to changes in habitat use and increased mortality among juveniles.
It is difficult to accurately determine habitat use and estimate the survival of juveniles in nursery areas based solely on their dedicated monitoring campaigns. This is why we will use acoustic telemetry, which involves implanting acoustic tags in fish whose movements are then detected by receivers located in the environment.
As part of this project, we will use acoustic telemetry on juvenile European sea bass in their nursery areas to identify their habitat ranges over a full year and estimate their natural mortality.
