Ocean pout

Ocean pout

The ocean pout (Zoarces americanus) is an eelpout in the family Zoarcidae. It is found in the Northwest Atlantic Ocean, off the coast of New England and eastern Canada. The fish has antifreeze proteins in its blood, giving it the ability to survive in near-freezing waters.

Scientists have done studies wherein genes are taken from the ocean pout and implanted into salmon in an attempt to make the latter grow faster. These genes transfer the ocean pout's tolerance for extremely cold waters to the salmon, allowing it to grow year-round. Controversy has arisen, as some view the altered fish as a potential threat to ordinary salmon if it is ever allowed to enter the wild. Nationwide, chefs, grocers and others have agreed not to sell the new fish over these concerns, though the fish is believed to be safe for human consumption.

In June 2006 the Unilever company announced that it would use genetically modified yeast to grow antifreeze proteins based on a gene from the ocean pout, and use it to improve the consistency and storage properties of its ice cream brands.
