Biological bases of methods for reproduction of carps

Abstract

The quality offish offspring is essentially influenced by methods of exploiting the producers both under natural and factory conditions. The pasture fattening the producers is given the essential influence by ways of producers’ exploitation both under natural and factory conditions. On producers pasture fattening there depend the qualities of sexual products, received after the injection of producers, as well as fertilizing opportunity of the sperm, way of embryogenesis and in future the offspring vitality at more late stages of development. Using hypophysis solutions for stimulating the ripeness of sexual products not seldom (at the absence of specialists) causes their bad quality, lowered viability of the offspring and nor seldom the death of producers themselves. The article gives biological bases of using the factory method of the reproduction.
