METHOD FOR FISH REARING IN POLYCULTURE OF FISH PONDS

摘要

FIELD: commercial fishery. SUBSTANCE: method involves supplying thermal water with temperature of 25-30 C and placing different age fishes in an amount of: carp 55-65%, wels 14-16%, phytophagous 9-12%, sanitary fishes 2-3%, predators 1-2%. In the process of fish keeping, water consumption is set to be at least equal to 2.0 m₃/sec per 100 tons of fish with water flow rate not exceeding 0.2 m/sec. Method further involves introducing combined feed with feed coefficient 3; maintaining required hydrochemical mode; periodically, each 6 months, filling fish rearing pond with fresh supply of carp and phytophagous fishes and conducting catching of commercial fishes. EFFECT: increased fish production, optimum characteristics of hydrochemical mode.
