One of the goals of the national strategy in the fishing sector in the use of multitrophic nutrition through which the increase of the aquaculture production quality is targeted. In this regard, the use of microalgae in aquaculture is a promising technology because they are the basis of the food chain due to their nutritional value. The microalgae cannot be used directly for fish growth, but indirectly as food for some mollusks or crustaceans. Microalgae are also used for some fish species, only for short periods of time during the early development stages, either directly or indirectly as part of their diet. The administration of microalgae in any growth stage has some advantages such as a better ratio between omega-3 and omega-6 compared to the conventional diets based on corn or soy, and a better taste of fish meat. The use of live microalgae suspension also improves the water quality in the recirculating aquaculture systems, removing the excess of the dissolved nutrients, and hence lowering the rate of the incoming water. In this context, the objective of this project is to build an integrated multitrophic system for the production of microalgae and crustaceans used for feeding the aquaculture sturgeons. The system will consist of two subsystems, a photobioreactor for the growth of microalgae and a reactor for the growth of crustaceans. The fotobioreactor will be operated in continuous regimen and the microalgae suspension will be sent to the crustaceans reactor as food. The obtained crustaceans will be harvested in semi-continuous regimen and administrated to the sturgeons in various growth stages.
