The various studies and work that I had performed allowed me to address various topics related to issues of management and the measurement of biodiversity for sustainable use of renewable natural resources.roblématiques de la gestion et de la mesure de la biodiversité en vue de l’utilisation rationnelle des ressources naturelles renouvelables.

The idea is to converge towards an integrated view of relationships between organisms and their environment to a better understanding of the functioning of ecosystems, in relationship with the socio-economic and human.

The various works, done in range of spatial and temporal scales, allowed to study organisms at different levels of organization ranging from the individual to the ecosystem.

Different tools were needed involving different disciplines, ethology, ecology, morphology and morphometry… Material being studied primarily continental freshwater fish.

The data collected were used in the context of fisheries management and development of farming (aquaculture).
