SNP及其在鱼类养殖中的应用

A Review of the SNP and Its Application in Fish-Farming

随着鱼类水产养殖业的不断发展,亟需对一些重要的养殖种群进行遗传性状的改良和良种的选育,而分子标记技术可以大大加快良种选育和性状改良的的过程。作为第三代的分子标记技术,SNP分子标记在一些实际应用当中体现出了比微卫星技术更优越,例如遗传稳定性高、高密度、便于自动化分析等优点。目前SNP在鱼类应用中比较少,因此有必要对SNP在鱼类养殖中的发展现状进行总结,这将对于后期SNP分子标记技术养殖中的发展起到推动作用。

With the development of fish-farming, genetic traits of some important breeding stocks need improving urgently. The technology of molecular markers can play a significant role in the process of selection and improvement for breeders and genetic traits. As the third generation of molecular markers, in some of the practical applications, single nucleotide polymorphisms （SNPs） markers appear to be better than the microsatellites, for example, stability, abundance, and automated analysis. However, SNP is relatively little used in the fish-farming, so it is necessary to review the status of current advance of SNP technology in the fish farming, which would promote the post-SNP breeding orogramdevelooment .
