IBASAM (Individual BAsed Salmon Model) is an individual-based demo-genetic model developed to simulate salmon population dynamics.

How does IBASAM work?

IBASAM is made of 8 submodels representing fundamental biological processes :

  • Reproduction and reddcreation
  • Emergence from the redds and individual birth
  • Genetic coding and transmission
  • Growth
  • Survival
  • Smoltification
  • Maturation
  • Migrations and dispersal

It also includes 2 environmental submodels :

  • River climate (Water temperature and flow)
  • Ocean climate

For the sake of conciseness, all submodels are not extensively justified here. Please see Wiki and Piou et al. (2012) for further explanations and graphics of some of the mathematical functions used.

How to use IBASAM?

More detailed explanations are provided in the Wiki.

What is IBASAM’ goal?

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.
