Corneille, S.; Noterdaeme, L.; Ollevier, F. (1989). Culture of sea bass larvae (Dicentrarchus labrax) in completely closed recirculation systems with artificial seawater. Aquaculture : a biotechnology in progress 1: 125-131
Sea bass larvae (Dicentrarchus labrax) were cultured under laboratory conditions in "completely"-closed recirculation systems with artificial seawater. Daily measurements ensured that the quality of the water was always under control. A 3-year survey of the bacterial population in this system revealed on the one hand, the permanent presence of Vibrio alginolyticus and Pseudomonas species and, on the other hand, a low bacterial concentration during the first 30 days of the rearing period. After 3 years of investigation, a larval survival of 22% was obtained at day 45. The growth rate was similar to that reported by other investigations (18,4mm at day 45). The major problems were: absence of the swimbladder, swimbladder hypertrophy, and a spinning movement syndrome or whirling disease.
