METHOD FOR CULTIVATING THROUGH PACIFIC SALMON Russian patent published in 2003 - IPC

FIELD: pisciculture. SUBSTANCE: the present innovation deals with stock raising of Pacific salmon - Siberian salmon, humpbacked salmon, hoopid salmon and red salmon, in particular. Fish breeders are trapped in coast waters to be kept in live fish tanks in sea without any feeding till complete maturation of reproductive products. Then they should be killed followed by separation of caviar and soft roe, caviar fertilization, transportation of fertilized caviar into incubators, caviar incubation, obtaining free embryos, larvae keeping, growing up young fish at artificial feeding and young fish releasing. Fish breeders could be killed due to either cutting bronchial artery or knocking fish head with a beater below its eyes to obtain reproductive products without blood clots and improve caviar quality during further incubation. Growing up young fish in fresh water could be carried out to obtain fish body weight up to 350-400 mg (Siberian salmon and humpbacked salmon) or up to 1000-2000 mg (Siberian salmon, hoopid salmon and red salmon) by applying artificial water heating up to 5-10 C by obtaining industrial label (there are more sclerites at fish scales against natural reproduction) that enables to identify and establish industrial label of returned mature fish breeders. Their meat after removal of reproductive products keeps carotinoid pigments and is of high nutritive value to be used in preparing high-quality products as a result of keeping fish breeders in coast waters without entering fresh water as it occurs during natural reproduction and conventional biotechnology of artificial fish breeding. After growing up in fresh water young fish are transported into live fish tanks in coast waters to be grown up there for 1-2 mo and then released into open sea. Young fish could be, also, released into sea water without any preliminary adaptation in subsaline water that refers, predominantly, to Siberian salmon and humpbacked salmon (350- 400 mg body weight) and relatively large hoopid salmon and red salmon youngsters (2000 mg body weight, and more) during the second half of June. EFFECT: decreased quantity of technological operations. 6 cl, 2 dwg, 3 ex, 3 tbl _
