The AquaAdvantage salmon 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. It is still unclear whether the public will have an appetite for the fish if it is approved. Genetic engineering is already widely used for crops, but the government until now has not considered allowing the consumption of modified animals. Although the potential benefits
-- and profits -- are huge, many people have qualms about manipulating the genetic code of other living creatures. If the salmon are eventually approved for sale, consumers may not even know they are eating them. According to federal guidelines, the fish would not be labeled as genetically modified if the agency decides it has the same material makeup as conventional salmon. AquaBounty says that genetically modified salmon have the same flavor, texture, color and odor as the conventional fish, and the FDA so far has not shown any signs of disagreeing. Wenonah Hauter, director of the advocacy group Food and Water Watch, said forgoing labeling not only ignores consumers' rights to know what they are eating, but "is simply bad for business, as many will avoid purchasing any salmon for fear it is genetically engineered." Hauter urged members of Congress to block the impending approval of the fish. Congressional opposition to the engineered fish has so far been led by members of the Alaska delegation, who see the modified salmon as a threat to the state's wild salmon industry.
Sen. Lisa Murkowski, R-Alaska, said Friday she is working to convince fellow senators that approval for the fish should be stopped. "This is especially troubling as the agency is ignoring the opposition by salmon and fishing groups, as well as more than 300 environmental, consumer and health organizations," she said of the preliminary approval.
