Promoting the sustainability of fish and crop farming using circular multitrophic aquaculture: the pilot experience of the PRIMA project “SIMTAP”
C. Jaeger, J. Aubin and V. Gayet: Associating seabreams, bivalves, and shrimp in a loop: the SIMTAP system in France
In aquaculture, loss of nutrients in the surrounding environment is an important concern. To maximize the use efficiency of nutrients, the system set up in France was designed to associate seabream (Sparus aurata) with three different organisms of commercial interest and differing from seabream for their trophic level.
To limit the pressure on environment, only local vegetal raw materials were used in the formulated fish feed. In addition, fresh discarded mussels, were directly supplied to the fish to balance their micronutrient and fatty acids needs.
Thus, the aim of this study was to assess the performances of this system, by monitoring the water quality and the growth performances of the different organisms reared.
