Egg and sperm quality in fish.

Abstract：

:Fish egg quality can be defined as the ability of the egg to be fertilized and subsequently develop into a normal embryo. Similarly, sperm quality can be defined as its ability to successfully fertilize an egg and subsequently allow the development of a normal embryo. In the wild or under aquaculture conditions, the quality of fish gametes can be highly variable and is under the influence of a significant number of external factors or broodstock management practices. For these reasons, the topic of gamete quality has received increasing attention. Despite the significant efforts made towards a better understanding of the factors involved in the control of gamete quality, the picture is far from being complete and the control of gamete quality remains an issue in the aquaculture industry. Some of the factors responsible for the observed variability of gamete quality remain largely unknown or poorly understood. In addition very little is known about the cellular and molecular mechanisms involved in the control of egg and sperm quality. In the present review, the molecular and cellular characteristics of fish gametes are presented with a special interest for the mechanisms that could participate in the regulation of gamete quality. Then, after defining egg and sperm quality, and how can it can be accurately estimated or predicted, we provide an overview of the main factors that can impact gamete quality in teleosts.
