Fish feed ingredients vary depending on the species. Most species require a certain amount fish meal and fish oil, but some fish can be vegetarian so there is a wide variety of fish feeds. The problem with raising salmon, shrimps and prawns is the high amount of fish oil needed. Vegetable oil can replace some of this oil, but not more than 50%. This high-quality fish oil is a major problem for some wild species that are overfished and could lead to the demise of fish farming. The replacement with vegetable oil has obviously reduced the omega 3 levels in salmon and should be verified.
