The effect of density on sea bass (Dicentrarchus labrax) performance in a tank-based recirculating system ArchiMer

Sea bass (Dicentrarchus tabrax) (135 +/- 4 g) were reared under tank-based recirculating aquaculture system for a 63-day period at four densities: 10, 40, 70, 100 kg m(-3). Fish performance, stress indicators (plasma cortisol, proteonemia plus other blood parameters-Na+, K+, glucose, pH, total CO2- and water quality were monitored. At the end of the 63-day period, resistance to infection was also studied by a nodavirus challenge. A 25-day test was performed on fish from two extreme densities (10 and 100 kg m(3)) and one intermediate density (40 kg m(3)). With regards to the different density treatments, there was no significant difference between the daily feed intake (DFI) and the specific growth rate (SGR) up to a density of 70 kg m(-3). No significant...

Effects of rearing density on sea bass (Dicentrarchus labrax) biological performance, blood parameters and disease resistance in a flow through system ArchiMer
Roque D'Orbcastel, Emmanuelle; Lemarie, Gilles; Breuil, Gilles; Petochi, Tommaso; Marino, Giovanna; Triplet, Sebastien; Dutto, Gilbert; Fivelstad, Sveinung; Coeurdacier, Jean-luc; Blancheton, Jean-paul.
During 84 days, the effects of density on juvenile sea bass (Dicentrarchus labrax) (76 +/- 16 g) were studied in an experimental tank-based flow through system. Performance, stress response and resistance to virus infection were analysed under five stabilized rearing densities: 10, 20, 40, 70 and 100 kg m(-3). Water quality parameters (CO2, total ammonia nitrogen and O-2) were measured and maintained close to the recommended values for farmed sea bass by adjusting water renewal exchange. No significant differences were observed between density treatments, neither on stress response (cortisol) nor susceptibility to nodavirus. With regards to biological performances, the daily feed intake and specific growth rate were significantly lower in fish reared at...
