| Abstract |
During the spring of 1974, 364,000 sea bass larvae, obtained from natural spawnings in captivity, were reared up to 1 month, in 60-500l tanks in 22 different experiments. The only food for the fish larvae, consisted of the rotifer Brachionus plicatilis Müller, and nauplii or metanauplii of the branchipod Artemia salina L. Larval density at the beginning of the experiments ranged from 28-154/l. It was reduced after 1 month to 2-32 larvae/l, the survival ranged from 3-69%. Under the experimental conditions employed, survival seemed to be strictly related to the daily feeding regime. Both survival and growth seemed to be independent from the size of the culture tanks and from the larval density. The nutritional budget of 30 day old fingerlings was calculated and growth curves (size and weight) established. |
