Isn't it better to buy farmed salmon? Leave the environment alone?
Serious question.
I'm unconvinced.
BSE came from cows being fed products made from cow. Chickens at least have had some recyling into their food. What are the fish fed to make the grow so quickly? I have visions of the liquified dead beign fed to the farmed people in the Matrix

Plus any intensive farming means disease can take hold easier and germs can mutate faster so we are asking for more species jumps like BSE harming people, chick pox and measles jumped species
Playing with fire with intensive farming, genetic modification, artificial this n that.
If we need so much seafood I think better of farming baby fishies and releasing them into the wild
I agree Mark, but unfortunately, the only way 'natural' salmon (and most other species consumed by humans) could possibly be sustained is with a vast change in human eating habits.
Farmed salmon are like any farm animal. The amount of feed (re; pilchards & other less desirable fish species) hugely outweighs the amount of produced edible meat from the fish. As with cows - the amount of grain & feed that goes into feeding a cow for its lifespan could feed many more than the beef produced (although I'd rather a nice juicy steak than a bowl of cereal).
Another issue with GM modified farmed fish (or fish fed GM modified food) - is that they escape, through either poorly-constructed nets, storms or sharks biting holes in the nets. These species breed with the wild fish stock & soon enough, it won't matter what kind of salmon you choose to buy - the choice will be made for us.
