METHOD FOR GROWING TO A GIVEN SIZE OF NON-STANDARD CRABS CAUGHT IN SEA FOR OBTAINING OF STANDARD PRODUCTS Russian patent published in 2006 - IPC A01K61/00 

FIELD: marine culture.

SUBSTANCE: method involves catching and selecting non-standard crabs during catching period before mass molting and spawning period; selecting from caught crabs male specimen of standard size with carapace width of at least 15 cm and filling of limbs with flesh of up to 50%; placing selected crabs into transportation reservoirs at crab settling density of 50 kg/m³ and transporting into tanks; disposing tanks in coastal zone of non-freezing gulfs or bays having depth of 5-25 m. Tanks are differently configured, have volume of at least 5 m³ and are provided with opening for supplying of feed for crabs into tank. Crabs are placed into tanks at crab settling density of 30-50 kg/m³ and fed with feed resistant to washing out and having negative floatability. Daily ration of balanced feed resistant to washing out is on the average 0.1-1.0% of crab biomass in tank, said ration being corrected depending on water temperature. Method allows high-quality standard product to be obtained from non-standard settling material during optimal time.

EFFECT: increased efficiency in growing of non-standard crabs to standard sized crabs.
