The aim of this experimentation was the evaluation of the nutritional quality of the micro algae produced with the outflow medium of a rotating biological contactors (RBCs)from aquaculture wastewater and used for growth of mussel Mytilus galloprovincialis specimen in RAS (Recirculating Aquaculture System). Nutritional parameters did not show any significant differences between algae cultured by classic methods (Guillard medium) and those produced with the RCBs treated waste. In addition, the molluscs growth, (soft tissue wet weight), did not show significant difference between the controls and the experimental groups fed with algae from the RBCs outflow. The system RCBs allows a meaningful biomass production from the biotechnological waste treatment, and also revealed an available procedure for the mussel growth to be use as an additive or substitutive live food in aquaculture fish diet.

Abstract
The aim of this experimentation was the evaluation of the nutritional quality of the micro algae produced with the outflow medium of a rotating biological contactors (RBCs)from aquaculture wastewater and used for growth of mussel Mytilus galloprovincialis specimen in RAS (Recirculating Aquaculture System). Nutritional parameters did not show any significant differences between algae cultured by classic methods (Guillard medium) and those produced with the RCBs treated waste. In addition, the molluscs growth, (soft tissue wet weight), did not show significant difference between the controls and the experimental groups fed with algae from the RBCs outflow. The system RCBs allows a meaningful biomass production from the biotechnological waste treatment, and also revealed an available procedure for the mussel growth to be use as an additive or substitutive live food in aquaculture fish diet.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
