The company combined growth hormones from Chinook salmon and a gene from the ocean pout, an eel-like species, to cause the new salmon to produce growth hormones year-round instead of only in spring and summer.
The gene construct consists of two parts, namely 1) a growth hormone gene from the Chinook salmon, and 2) a promoter gene from another fish, called ocean pout which switches on the growth gene all-year round instead of only during warm weather.
AquAdvantage, the fast-growing fish at the center of the controversy in the United States, is an Atlantic salmon that contains a growth hormone from a Chinook salmon and has been given a gene from the ocean pout, an eel-like fish.
aspx) AquAdvantage salmon , is a farmed Atlantic salmon that contains a growth hormone gene from the chinook salmon and a genetic switch from the ocean pout that keeps the transplanted gene continuously active.
Food and Drug Administration (FDA) is expected to decide on the first-ever genetically engineered (GE) nonplant food source for human consumption--a proposal by Massachusetts-based AquaBounty to sell sterile eggs of a salmon with genetic material from the Chinook salmon and the ocean pout inserted for fast growth.
Scientists in the United Kingdom are rejecting the proposed use of a synthetically produced "is a replica of a naturally occurring one that Unilever has copied from the ocean pout, a fish that lives in the extremely cold waters of the bottom of the Northern Atlantic Ocean.
