Fish used
Fish meal can be made from almost any type of seafood, but is generally manufactured from wild-caught, small marine fish that contain a high percentage of bones and oil. Previously, these fish have been considered unsuitable for direct human consumption, but more recent research indicates the vast majority of fishmeal made from whole wild-caught fish is made from fish suitable for direct human consumption. Other sources of fishmeal are from bycatch and byproducts of trimmings made during processing (fish waste or offal) of various seafood products destined for direct human consumption.
