Importância da avaliação dos parâmetros reprodutivos em peixes nativos

Abstract

The reproductive capacity of large migratory fish is dependend of environmental stimuli that are responsible for the synthesis and release of pituitary hormones, FSH and LH. From these stimuli began the process of development and maturation of the gonads, culminating in spawning. But in captivity, the environment is not capable of reproducing the natural stimuli for breeding, requiring hormonal induction. When the hormonal induction is performed, there is a necessity to develop new techniques for evaluating the gametes, increasing the reproductive efficiency. So this review is aimed to focus on different techniques for reproductive assessment, both for male and female, identifying new methods and techniques and support the use of those that are already consolidated.
