Des systèmes intégrés multi-trophiques pour une aquaculture durable ArchiMer
Hussenot, Jerome; Richard, M..
Within the SEACASE European project on sustainable extensive and semi-intensive aquaculture in Southern Europe (SEACASE), an information day on integrated multi-trophic aquaculture systems (IMTA) has been organized by Ifremer in Rochefort sur Mer, with the participation of other French partners of the project. After presenting the concept of IMTA, modern polyculture, the contents of the European research project SEACASE, and recent research carried out also were exposed. The interest of these systems and their implementation in future years to develop sustainable aquaculture has been discussed in a debate between the various participants.

Integrated multi-trophic aquaculture (IMTA) systems are a promising solution for sustainable aquaculture combining nutrient recycling with increased biomass production. An innovative land-based recirculating aquaculture system (RAS) was studied in France for a 60-day experiment. It combined a European sea bass (Dicentrarchus labrax) RAS with two other production systems: high rate algal ponds (HRAP) with natural marine polyspecific algal assemblages, and oysters in separate open tanks. The objective was the assessment of: 1) the efficiency and the stability of the microalgae bioremediation of the effluent from a fish RAS in spring and summer, 2) the abundance and the diversity patterns of the microalgae biomass for consumption in the oyster compartment of...

An integrated fish-plankton aquaculture system in brackish water ArchiMer
Gilles, S.; Fargier, L.; Lazzaro, X.; Baras, E.; De Wilde, Nicolas; Drakides, C.; Amiel, C.; Rispal, B.; Blancheton, Jean-paul.
Integrated Multi-Trophic Aquaculture takes advantage of the mutualism between some detritivorous fish and phytoplankton. The fish recycle nutrients by consuming live (and dead) algae and provide the inorganic carbon to fuel the growth of live algae. In the meanwhile, algae purify the water and generate the oxygen required by fishes. Such mechanism stabilizes the functioning of an artificially recycling ecosystem, as exemplified by combining the euryhaline tilapia Sarotherodon melanotheron heudelotii and the unicellular alga Chlorella sp. Feed addition in this ecosystem results in faster fish growth but also in an increase in phytoplankton biomass, which must be limited. In the prototype described here, the algal population control is exerted by herbivorous...
