史氏鲟(Acipenser schrenckii Brandt),是中国现存鲟鱼中最具经济价值的鱼类,有个体大、成活率高、生长速度快、肉质鲜美等特点。鲟鱼最有价值的产品是鱼子酱,素有“软黄金”之称,因此史氏鲟养殖主要有商品鱼养殖和亲鱼养殖两种方式。商品鱼养殖,一般养殖时间为一年,体重约0.5~1.0 kg;亲鱼养殖是指史氏鲟在养殖3~4年辨出雌雄后,雄鱼淘汰作为商品鱼上市,体重约3~5 kg;雌鱼养殖至7~8年用于生产鱼籽酱,取完鱼籽的鱼体俗称壳,也用作商品鱼上市。近几年,国内外对史氏鲟的研究逐渐展开,内容主要集中在人工繁殖技术[1]、生物化学[2]、遗传发育[3]、组织形态[4]等方面,对史氏鲟商品
Acipenser schrenckii Brandt is one of the most economically valuable fish species in China. It has the characteristics of big individual, high survival rate, fast growth rate and delicious meat. Sturgeon is the most valuable product caviar, known as “soft gold ”, so the history of sturgeon breeding mainly commercial fish farming and broodstock breeding in two ways. Commodity fish farming, the general breeding time of one year, weighing about 0.5 ~ 1.0 kg; broodstock farming refers to Amur sturgeon 3 to 4 years after breeding identified male and female, the male fish out as a commercial fish market, weighing about 3 ~ 5 kg ; Females aquaculture to 7 to 8 years for the production of caviar, take fish roe fish body commonly known as the shell, but also for the commercial fish market. In recent years, the research on Sturgeons in the world has been gradually carried out. The main contents are as follows: Artificial propagation [1], Biochemistry [2], Genetics and Development [3], Morphology [4] commodity
