Both are now raised on commercial farms with great success and have been for years with no effect on the wild populations. In fact, farm raised catfish and trout both took much of the overfishing problem off the wild populations. There is no reason to suppose it would be any different for salmon, lobster or any other aquatic life.
Good point.
Consider, Wild Turkeys are extremely smart and difficult to hunt. They have a keen sense of sight, and many hunters come home with nothing to show for their efforts.
Contrast this to commercially grown turkey; these animals are so stupid that you put marbles in the feed trough to get them to eat. They peck at the marble, and miss and accidentally get a mouth full of food. They are kept indoors because they will look up when it rains and drown themselves.
Yet, these huge commercial birds do not contaminate the wild birds. Essentially these birds are too stupid to survive outside of a commercial farm.

I’m not taking a stand on this pro or con. I do find there to be some reasoned questions concerning it though.
Those fish farms generally raised large numbers of traditional fish, perhaps engineering them to be an improved version.
These are a little different, in that they are genetically engineered.
What happens when these fish are introduced into streams across the nation. Let’s be frank. It will happen.
Is it of concern that the original fish may be eradicated by this dominant version? Could other fish be impacted negatively if that happens?
I don’t think this is without any possible negative aspects.
It isn't even a question of selectively breeding those species to have a new breed suited to aquaculture.
It is a question of creating new traits which do not exist in nature, and the consequences of those organisms getting into the wild, should that happen.
Any organism which grows twice as fast will require both growth hormones and food. Release this super-eater into the wild and the effects on those other critters (prey) in the food chain and those other organisms (other predators) who depend upon them might be a disaster.
That said, I would want the 'engineered' food clearly labelled so I would have the option of not buying it, instead of put on the market as if it were identical to the wild or even aquacultured natural fish.
In Europe, mussels are farm-raised in fjords within enclosed areas. I’ve seen them being harvested in Ireland.
You are absolutely correct. However the folks with money and S**t for brains will spend money on the other form of scum. Namely greedy lawyers to control everyone else. And its all about control and the “Chicken Little” principal which they seem to have in abundance.
