我国科学家在一项基因工程研究中利用国产鱼生长激素喂养鱼苗,大大缩短了人工养殖高档经济鱼的周期。 当前,我国主要经济鱼类的养殖方法是采用网箱和池塘养殖。一般的海水鱼类的养成周期都在一年以上。为缩短养鱼周期,科学家将目光放在了生长激素——脊椎动物脑下垂体分泌的一种单链蛋白质上。从1992年开始,我国海洋局第三海洋研究所的研究人员在国内率 Chinese scientists used domestic fish growth hormone to feed fry in a genetic engineering study, which greatly shortened the cycle of culturing high-grade economic fish. At present, the breeding method of the main economic fish in our country is cage breeding and pond culture. The general seawater fish development cycle are more than a year. To shorten the fish-farming cycle, scientists are eyeing a single-chain protein secreted by the growth hormone, the vertebrate pituitary gland. Since 1992, researchers at the Third Institute of Oceanography of the State Oceanic Administration have made a national rate
