Genetically-engineered AquAdvantage salmon

Question:
Genetically-engineered AquAdvantage salmon has received approval for sale in the United States as food, without special labeling.

To make it grow and mature faster, it uses a “genetic promoter” from the “ocean pout,” a tameh fish.

Does this present a halachic problem for the consumer?

Answer:

In the Rav’s opinion there is no concern with this fish. Ultimately it is a kosher fish with kosher simanim, which is the criteria for determining the status of the fish.

An extensive teshuva on the issue is be”h forthcoming.
