马萨诸塞州公司AquaBounty培育了AquAdvantage这一三文鱼品种。该公司CEO罗恩·斯拖提希在一次声明中表示,该品种三文鱼是一个革命者,它将给消费者带来健康营养的食物,并且承担起环境责任,不损害海洋及海洋生物。
The fish grows twice as fast as normal salmon, so it reaches market size more quickly. It has an added growth hormone from the Pacific Chinook salmon that allows the fish to produce growth hormone all year long. The engineers were able to keep the hormone active by using another gene from an eel-like fish called an ocean pout that acts like an "on" switch for the hormone. Typical Atlantic salmon produce the growth hormone for only part of the year.
这种鱼的生长速度是普通三文鱼的两倍,能更快速地上市。它体内含有从太平洋奇努克三文鱼身上提取的激素,可以使之一整年不断产生生长激素。工程师用另一种类似鳗鱼的大洋鳕鱼基因保持生长激素的活跃,促进AquAdvantage三文鱼生长。普通三文鱼一年内只有部分时间产生生长激素。
The FDA has also said the fish is unlikely to harm the environment. The fish would be bred female and sterile, though a very small percentage might still be able to breed. The company has argued the potential for escape is low.
食品药品管理局表示该鱼种损害环境的可能性很低。只养殖了雌鱼和绝育鱼,仅有一小部分仍能繁殖。该公司称流入自然的可能性很低。
