Some day soon, you might tuck into a plate of salmon without knowing that the fish you are eating was genetically engineered. The so-called AquAdvantage salmon, a salmon genetically engineered to grow faster than normal salmon, just moved one step closer to legalization. If so, it will be the first genetically engineered (GE) animal allowed for consumption in the United States. Thus, every part of the regulatory process related to the GE salmon sets a precedent for all future GE animals in the United States — and so far, according to experts, that precedent is a sloppy, inadequate one.
To create the GE salmon, the Boston-based public company AquaBounty Technologies inserted DNA from another salmon species and an eel-like fish into the genome of an Atlantic salmon. The new genes make the GE salmon produce growth hormone all year round instead of just for three months a year as they normally would. This helps them grow to market size in 16 to 18 months instead of the usual 30 months required for an Atlantic salmon.
To prevent any GE salmon from escaping into the wild, surviving, and reproducing there, AquaBounty will only produce female GE salmon, each with three sets of DNA instead of the normal two. Triploids, as organisms with three sets of DNA are called, are infertile. Therefore, producing only female, triploid GE fish should provide two mechanisms of preventing reproduction should any fish escape into the wild. (Obviously, it takes a bit of scientific tinkering to create an all-female triploid fish population and the process used to do this might make your stomach turn.)
AquaBounty will produce salmon eggs in Prince Edward Island, Canada. Then it will transport them to an inland facility in Panama, where it will grow the fish, harvest, and process them. The firm claims no live fish will ever enter the United States. (Read more)
