Invention belongs to fishery. In the first 15 days after the transition to active eating, the food of seedlings was contained in water tanks, with a density of 1 do-150000 parts, a / m3 and a water exchange rate of 5-6 L / min. Since then, the planting density has decreased to 50000-70000 tons. Part:Water exchange speed increased to 7-8 L / min. During the whole growth period, the initial feed at 2-2.5 hours was mixed at 100-50% body weight. When the average mass reaches 37-40 mg, it is released into the natural water body. Page: 1
