The project aims to develop IMTA strategies for fish farmers to develop new production systems being efficient, economically attractive, robust, and environmentally friendly. For this purpose, the project points to provide scientific references on the nutrient and energy efficiency gains generated by associating different aquatic species of different levels in the food web. Two basic production systems with various forms will be studied: multi-trophic marine systems and freshwater polyculture systems. These systems are divided into two modalities: 1- species reared separately in different structures permitting a precise measurement of each species activities and role in nutrient and energy cycling, 2- Species reared all together in the same structure, showing an overall result of species interactions. These two modalities will be used to develop and calibrate bio-energetic and bio-physic models. These different case studies will permit to understand the functioning and the efficiency of each compartment of the systems, and their interactions in the different contexts.
