物种进化与鱼类育种的发展*

 从遗传学角度讨论了物种进化、生物多样性以及鱼类育种三者之间的内在联系；从渔业可持续发展的角度分析了物种灭绝对生物多样性的影响和鱼类育种对生物多样性的贡献；从选择育种、杂交育种、倍性育种、航天育种、细胞工程育种以及基因工程育种等几个方面简要综述了鱼类育种技术的发展；探讨了鱼类种质检测与品种筛选技术以及鱼类育种的发展前景。

Species Evolution and Development of Fish Breeding

The internal connecting link among species evolution, biodiversity and fish breeding was discussed on the point of genetics. The species extinction's affect to biodiversity and the fish breeding's contribution to biodiversity was analyzed on the point of fishery sustainainable development. The development of fish breeding technology was summarized briefly on choosing breeding, crossing breeding, ploidy breeding, spaceflight breeding, cell engineering breeding and gene engineering breeding. The fish germplasm detection, the variety screening technology and the developmental prospect of fish breeding was also probed into at last.
