The Frankenfish Rises

Yeah, I know it's just a genetically modified salmon, but Frankenfish is the name it was given and it sure has stuck. And why not? This is a "salmon [that] has been modified by the addition of a growth hormone regulating gene from a Pacific Chinook salmon and a promoter gene from an ocean pout to the Atlantic's 40,000 genes. These genes enable it to grow year-round instead of only during Spring and Summer. The purpose of the modifications is to increase the speed at which the fish grows, without affecting its ultimate size or other qualities." (Wikipedia)

The AquAdvantage salmon (to address it by its proper name) is intended to be raised in on-land fish farms from supplied eggs and is expected to grow at least twice as fast as a normal Atlantic salmon. Of course, that does mean it needs to eat an enormous amount.
