I really like your idea of alternative methods to wild fishing. This is very important, as we can’t simply reduce fishing effort without some substitute. Like Greenburg said,it is important to choose fish that will work for aquaculture. Fish with low feed conversion, at least as good as our terrestrial animals, that breed well in captivity, and have low capacity to harm wild stocks. I also agree that altering of the fish genome is a good idea, as that would allow us to further improve the efficiency of farmed fish.
