Scientists discover key to easing aquaculture's reliance on wild-caught fish

For the first time scientists have been able to develop a completely vegetarian diet that works for marine fish raised in aquaculture, the key to making aquaculture a sustainable industry as the world's need for protein increases. "This makes aquaculture completely sustainable," said Dr. Allen Place. "The pressure on natural fisheries in terms of food fish can be relieved. We can now sustain a good protein source without harvesting fish to feed fish."
