My activity

My research activities at ISEM are focused on the evaluation and design of integrated aquaculture systems according to the principles of ecology (e.g. food web, species assemblages, nutrient flows), in a view to optimize their productivity. My study model favours aquaculture systems integrated with agriculture such as rice-fish farming. I am also particularly interested in the study of the impact of anthropogenic and fish-farming effluents on the functioning of aquatic ecosystems, in order to characterize the health and environmental risks specific to aquaculture. Ecologist, my skills reinforce those of the DIVA team, in particular in the analysis of trophic flows in multitrophic integrated aquaculture systems. To do this I use the method of natural stable isotopes of Carbon and Nitrogen (d13C & d15N), fatty acid markers, biodiversity indicators, nutrient fluxes and the presence of Trace Metal Elements in the environment and in aquaculture products.
