Bidasoa is a research and management module. It simulates the dynamics of brown trout (Salmo trutta) populations in a spatially explicit watershed, accounting for fragmentation of environment. Watershed is built using reach and weir objects, all connected by a tree structure. Fish are individualized, they grow, die, reproduce depending on habitat quality and have their own genotype (extension Genetics 2.0). They can follow migration routes with respect to connectivity. All demographic routines can be parameterized. Larval stages can use “hatch” objects that group huge numbers of larvae, in order to limit memory consumption. Fishing interventions are possible.

The inventory file includes the species data, genetic map data, individual fish data, reach and weir data.
