A Review on the Reproductive Dysfunction in Farmed Finfish

Globally, fish production in the wild is decreasing, and different aquaculture systems are presently being used for broodstock development captivity. Seasonally, raised captivity exhibit form of reproductive dysfunction at level brain-pituitary-gonad (BPG) axis. Primarily, vitellogenic completion final oocyte maturation inhibited females, males fail to spermiate spontaneously Reproductive dysfunctions also observed during sexual differentiation, pubertal onset sex conversion periods teleosts. To overcome these problems, hormonal preparations, primarily gonadotropin-releasing hormones (GnRH) used. In recent years, kisspeptins have been shown be potent inducing gonadal growth teleost fish. Understanding important formulating suitable preparations gametogenesis. The paper reviews problem their possible reason preparations.
