After six months of relative media silence, GMO salmon are back. Since last fall, AquaBounty Technologies, the breeders of the fish — which is not to be confused with radioactive tuna — have been in a kind of regulatory limbo, awaiting approval by the Food and Drug Administration (FDA).

Then this week, several GMO salmon stories popped up in the media, and, taken together, they suggest it might be time to take another look at the salmon, which would be the first genetically engineered animal raised for commercial consumption if it’s approved.

The fish, which is branded AquAdvantage, has been altered with a growth-hormone gene from a Chinook salmon and a gene from a deepwater eel-like fish called an ocean pout. The latter allows the fish to grow during the cold months and reach market size twice as fast as other salmon.
