METHOD FOR FORMING CARP BREEDER SHOAL

摘要

FIELD: commercial fish breeding. SUBSTANCE: method involves two-staged mass selection by fish chronic hypoxia and weight resistance; performing chronic hypoxia resistance selection at larva and one-year age with intensity of 30-40% in each age-group; performing weight selection among one-year and two-year age-groups, with 50% of species being left for breeding. Total selection intensity in two-year age-group is 0.9-1.6% of number of larvae used for selection by resistance to water oxygen deficit. Method allows high intensity selection to be kept. EFFECT: increased vitality and productivity of objects supposed for breeding. 3 tbl, 3 exn
