Modelling the Future of Stocked Fish: chap. 30
Résumé
Stocking with juvenile sturgeon is a key point of the action plans described below for A. sturio. It is essential to assess the expected effects of these stocking measures in order to improve practises. Using a few parameters of population dynamics assessed from monitoring some cohorts, we simulated the survival of the stocked fish. Simulations are obviously highly sensitive to the mortality rate. Based on simulations using the best range of available parameters for the Gironde population, the number of females on spawning grounds constitutes a bottleneck for the dynamic of this population.
