The study of fish life strategies for fisheries management and conservation

The organism’s life history strategy includes fundamental biological characteristics, or life traits, such as its age and size at first reproduction, number of reproductive cycles, fecundity, growth, survival, the reproductive effort it allocates to each clutch, and so on. The existence of a species, its evolution and its maintenance in a given environment depends on the life history strategies implemented to adapt to the environmental constraints it encounters. Because of the major economic and food interests they represent, particularly in tropical regions, fish are one of the most exploited and threatened links in aquatic biodiversity and therefore require appropriate management, based on precise knowledge of the life traits of the species. In this presentation, I will attempt to illustrate the research that I am carrying out, in collaboration with partners in the South and students, on the life strategies of fish and their interest in the management of exploited species and their conservation.

Tutelles MARBEC



MARBEC MARine Biodiversity, Exploitation and Conservation, is a research unit which includes the staff of 4 organizations: IRD, IFREMER, UM and CNRS. Its objective is the study of marine biodiversity in lagoon coastal and offshore ecosystems, at different integration levels, molecular, individual, population and community aspects and the way humans use this biodiversity.
