Studies on the production of sea bass, Dicentrarchus labrax, under different rearing and feeding conditions: effect of dietary protein sources on the growth performance, feed utilization and profitability of sea bass post larvae, Dicentrarchus labrax [electronic resource].

Includes reference.

Six experimental diets were formulated; a fish meal based control diet (1), and five diets in which 25 %of the fish meal was substituted with either algae, liver of cartilages, clams and liver of beef or shrimp meal (diet 2, 3,4,5 and 6,respectively). The diets were fed to sea bass post larvae (Dicentrarchus labrax) over a 105-day experimental test period. Growth performance, survival rate and feed utilization parameters . The best in fish fed diet (3) containing 22% liver of cartilages, followed by fish fed diet 5,6.4.1 and 2 respectively. Considerable saving in feed costs was achieved when liver of cartilages was used as a partial dietary substitute inside fishmeal within compound feeds for sea bass post larvae statge, about 22.7%.
