加拿大的科学家采用遗传工程技术培育出一种巨型娃鱼，它比普通娃鱼要大十多倍。科学家们将一种非常活跃的生长激素基因注入到太平洋娃鱼的鱼卵中，结果，经过基因重组的新种鲜鱼比普通娃鱼长得又快又大，其平均重量为普通娃鱼的11倍。据说这种巨型娃鱼是人类利用基因技术培育 Canadian scientists have used genetic engineering to breed a giant fish that is ten times bigger than a common fish. Scientists injected a very active growth hormone gene into the Pacific oyster’s fish eggs. As a result, the genetically modified new species of fish grow faster and larger than the common fish, with an average weight of 10 11 times. It is said that this giant fish is human use of genetic technology to cultivate
