METHOD OF HIGH-INTENSITY GROWING OF TURBOT FLATFISH FRY Russian patent published in 2015 - IPC A01K61/00 

FIELD: agriculture.

SUBSTANCE: in compliance with this process, pool is filled with sterile sea water to 2/3 of it volume, water temperature making 18.0±0.5°C 2 days before addition of larvas at initial density of 40-50 species/l, and subjected to two-level air purging. Rotifers are introduced 12 hours before the beginning of external feeding and for 6 hours after said beginning concentration of rotifers is increased to 3 species/ml. Then, for days-old species, addition is increased to 4 species/ml while to 13 days-old species, larvas are fed with rotifers by portions. Density of rotifers is, first corrected every 6 hours (to 7 days-old species) and, then, every 12 hours (up to 13 dais-old species). In 12-13 days-old period larvas are fed with addition of brine shrimp larvas at the rate of not over 0.1 species/ml (once a day). 14^th-15^th day, larvas are fed with brine shrimp metanauplius while from 18^th-19^th day feed is complemented with copepod copepodites (0.1 species/ml). 30^th-35^th day, larvas are fed with inert trial feeding at increase in duration of first feed with inert feed to 3 hours for gradual replacement of feeding with 2-day saturated brine shrimp metanauplius. 40-45-days-old larvas are changed to inert feed at adding of copepod 2 times a week at the rate of at least 100 copepods per larva.

EFFECT: better artificial conditions for growing for commercial production.
