Was your take away from my post that I was against farmed salmon? I'm most definitely not. If you followed the thread you would observe that I was commenting on the means of farming fish are already improving; I was merely providing some info with regards to the post I quoted.
With that said... there is farmed salmon and there is farmed salmon. I have sampled both wild Atlantic salmon and the Norwegian Atlantic salmon that comes from farms : I couldn't tell the difference. The fat content, texture, and flavor was the same. Now, salmon from the more fresh water farms, or farms that use small pens... looking at the steaks you can see the difference in the fat content alone, the texture of the meat was considerably different and the flavor in the fish coming from a more fresh water farm was significantly less than that coming from an fish farmed in the open ocean. Open ocean salmon definitely tastes better than salmon coming fresh water or small pen fish farms. Though, maybe, this is similar to the steak thread where some people think a well done steak tastes good.
