摘　　要：鲟鱼是一类古老的大型经济鱼类,由于过度捕捞和人类对其生态环境的破坏及其鲟鱼自身具有的性成熟时间长、幼体成活率低等特点,使世界范围内的鲟鱼自然资源日趋枯竭。人工养殖鲟鱼已是鲟鱼制品的主要来源,但由于种质来源不清及大量杂交鲟的存在导致种质混乱情况比较严重,目前国内外均未有一套比较完善可行的鲟鱼种质鉴定体系。总结了目前进行鲟鱼种质鉴定的一些常用方法,分析了各个方法的优缺点,为确立一套稳定可靠的鲟鱼种质鉴定方法奠定基础。Sturgeon is a kind of large economic fish. Due to overharvesting, habitat destruction and their biological characteristics such as sexual maturation at a late age and low survival rate of larvae, sturgeon natural resources in the world were depleting. In order to meet the needs of sturgeon caviar and meat, artificial cultivations were developed and had been the main source of sturgeon products. So far, there was not yet a perfect germplasm identification method in sturgeons at home and abroad. Some common sturgeon germplasm identification methods were summarized. The advantages and disadvantages of each method were analyzed and listed. It was helpful to establish a stable and reliable sturgeon germplasm identification method.
