The crux of the matter is that GM salmon can not survive in the wild because they depend on unlimited food supplies at all times. They would starve in the wild.
Experiments have been done with other GM fish in Japan I think about ten years ago. When they are interbred with normal fish and then followed from generation to generation it leads to extinction of the lot in 6-7 generations. When this happens with salmon, it is only matter of time, the only salmon left will be farmed salmon and the price will go through the roof. Which is maybe the long term idea behind it.

age shows how the GM fish grow far more quickly

The potential risks of genetically modified fish escaping into the wild
have been highlighted in a new study.

Scientists from Canada have found that transgenic Atlantic salmon can
cross-breed with a closely related species - the brown trout.

The fish, which have been engineered with extra genes to make them grow
more quickly, pass on this trait to the hybrid offspring.
The research is published the Proceedings of the Royal Society
