硬骨鱼类卵子质量研究进展

鱼类卵子质量被定义为卵子受精和随之发育成正常胚胎的能力,其质量的优劣是影响鱼类人工繁育成败的关键因素,对养殖产业高效、可持续发展具有重要意义。本文就硬骨鱼类卵子质量的研究现状进行了概括及评析,从硬骨鱼类卵子的发生发育规律、卵子质量评价标准、影响卵子质量的内外因素及相关调控机理等方面进行了综合评述,并对今后硬骨鱼类卵子质量研究发展趋势进行了展望,旨在为硬骨鱼类卵子质量标准评价体系的建立提供科学依据,同时为海水养殖鱼类种苗生产提供可控性强的工艺流程。

Advances in teleost egg quality research

Fish egg quality can be defined as the ability of the egg to be fertilized and subsequently develop into a normal embryo.Egg quality determines the artificial breeding,affects the efficient and sustainable development of the industry in marine fish culture.In this paper,progress on the study of fish egg quality has been summarized in detail,which focuses on the oogenesis and development,evaluation criteria and influencing factors of egg quality,together with the underlining mechanisms.Meanwhile,further elucidate regulatory mechanism of egg quality and will provide the scientific basis for egg quality assessment in teleosts,thus providing controllable process of seed industry in marine fish culture.
