Aquaculture, the process of farming fish for human consumption, continues to be a hot topic, especially when it comes to salmon. Opponents of the salmon farms point to genetic modification and increased competition when farmed salmon escape and interact with wild salmon.
Proponents say salmon farming takes pressure off threatened stocks of wild salmon and helps make the healthy and delicious fish affordable. My take is: If you have to feed farmed salmon a supplement just to make their flesh pink, there’s something wrong with the whole process. (You can find out more about why you should eat wild salmon at Trout Unlimited’s Why Wild Website.)
In South America, there’s an effort underway to save threatened populations of Paiche, a large freshwater fish native to the Amazon, by reintroducing farmed fish to the river.
