METHOD FOR GROWTH OF YOUNG FISH OF AZOV-CHERNOMORSKAYA ROYAL FISH IN PONDS Russian patent published in 2009 - IPC A01K61/00 

FIELD: agriculture.

SUBSTANCE: method includes autumn preparation of breeders, their maintenance in hibernating ponds till spawning temperatures, hormonal stimulation of carp or bream by hypophysis in doses of 6-7 mg/kg, incubation of roe, maintenance of embryos in piscicultural reservoirs before transition to exogenous nutrition.

Mineral fertilisers are introduced into dry bed. Transfer of worms is done in two stages with interval of 7-10 days. Density of placement makes 1-3 mln.pcs./ha. Prior to placement of worms, ponds are previously filled and drained.
