A demo-genetic individual-based model for Atlantic salmon populations


What is IBASAM?

IBASAM (Individual Based Atlantic Salmon Model) is an individual-based demo-genetic model developed to simulate S. salar population dynamics in southern European populations.

IBASAM is a cohesive and novel tool to assess the effect of potential stressors on evolutionary demography of Atlantic salmon. It includes a demo-genetic structure coupled with the explicit representation of individual variability and complex life histories.

More detailed explanations (processes, installation procedure,…), are provided in the Wiki.
