加拿大的科学家采用遗传工程技术培育出一种巨型鲑鱼,其个体要比普通鲑鱼大10多倍。科学家们将一种非常活跃的生长激素基因注入到太平洋鲑鱼的鱼卵中,结果,经过基因重组的新种鲑鱼比普通鲑鱼长得又快又大,其平均重量为普通鲑鱼的11倍。据说这种巨型鲑鱼是人类利用基因技术培育出的转基因动物中生长最快的一种, 埘鱼类养殖业具有重要意义。 Canadian scientists use genetic engineering to breed a giant salmon that is more than 10 times as common as an ordinary salmon. Scientists injected a very active growth hormone gene into Pacific salmon roe eggs. As a result, genetically engineered new species of salmon grow faster and larger than normal salmon, with an average weight 11 times that of common salmon. It is said that this giant salmon is the fastest growth of transgenic animals cultivated by human using genetic technology, mackerel fish culture industry is of great significance.
