Description
A comparative test of various inert diets was performed on 9 batches of 150 one month old soles, wheighing an average 42 mg, and feeding on live brine shrimps. It lasted for 2 months, in 60 l square tanks, with sand bottoms. . A succession of frozen natural feed, ending with the Bivalve Laevioardium arassum, was compared to 2 different artificial diets, offered as dry pellets. The inurement to the pellets was facilitated by an incorporation of various meals, used as flavourings, during a 6 weeks transitory period. - At the end of the experiment, the best result, 98 % survival, average weight . 1.10 g, was obtained with the natural feed. The best flavourings for dry pellets were Laevi- cardium arassum and the Polyahaete Nephthus hombergii, with 70 % survival and 0.99 g for the first one, 52 % survival and 1.10 g for the second one. The possible reproduction of these results on a large scale is not yet demonstrated
