Project objective

Small pelagic fish are of much economic importance and are known to be subject to population crashes. Whether fishing pressure is responsible for the collapses is still unresolved. However, these collapses seem to be characteristic of clupeoids. Analysis of both the relationsl ips between populations and their histories using molecular data has proved useful and original. However, in classical approaches, population sizes are usually held constant through time. Theoretical and statistical properties of population size variations have, in the past, been poorly studied. Recently, a great deal of work has focused on the specific signatures of past and recent demographic events (expansions, bottlenecks) on the molecular genetic structure of a species. We propose to apply new statistical analyses developed in human population genetics to Sardinella aurita, a pelagic fish of great economic importance in West Africa. We also propose to develop simulations that could help understand the risks of extinction under various scenarios.
