摘要
FIELD: sea fish-farming. SUBSTANCE: on 2nd or 3d day after peck-out, the larvas are transferred to large rearing vessels with depth of at least 0.8 m filled with clean filtered sea water. They are kept there without water running and with partial changing of water for fresh one with dosed introduction of one-cell algae and starting live food at the beginning of mixed feeding. Then, on 7th-10th day, water is subjected to running, and on the 16th-18th day the larvas are transferred again into small breeding basins 0.4-0.8 m deep, and not later than the 40-day grown larvas are fed with rations of inert food. Besides, one-cell algae and starting food organisms are grown separately and introduced locally to places of larva accumulation to maintain total concentration of algae of 104 cell/ml and of live organisms 1-3 ex/ml, and water running started on the 7th-10th day is gradually increased from 2-3 volumes per day to 2-3 volumes per hour to the end of larva methamorphosis. EFFECT: higher efficiency. 3 cl
