low price nutrient-rich fish feed plants

Until recently, fish meal was the chief protein source in the fish feed for diverse reasons collectively for its high protein content, excellent essential amino acid (EAA) profile, better nutrient digestibility, lack of anti-nutritional factors (ANFs), low price and ease in its availability.

No. Fish nutritional needs vary by species. Herbivorous fish eat a feed mixture that may contain plant proteins (e.g., soy, corn), vegetable oils, minerals, and vitamins. In the wild, carnivorous fish such as salmon eat other fish.
