Induction of final oocyte maturation in Cyprinidae fish by hypothalamic factors: a review

Popis výsledku v původním jazyce

Most of the cyprinids reared under controlled conditions exhibit signs of reproductive dysfunction, which is manifested in the failure to undergo the final oocyte maturation and ovulation. This dysfunction is invoked by insufficient stimulation of sensory organs of the fish reared in the environment of fish farms lacking natural final oocyte maturation inductors. As a result, a disruption of endogenous gonadotropin-releasing hormone stimulation occurs and sequentially that of luteinizing hormone, whichis inevitable for the final phases of gametogenesis. In addition to the methods using the application of exogenous gonadotropins, the usage of method functioning on the basis of hypothalamic control of final oocyte maturation and ovulation has been preferred recently. This was made possible mainly because of detailed knowledge of the gonadotropin-releasing hormone system and gonadotropin-releasing hormone forms of fish with the identification of a Dopamine inhibitory factor.
