Question

i need four processes used to produce fish meal

Answer 1

Fish meal, or fishmeal, is a commercial product mostly made from fish that are not generally used for human consumption; a small portion is made from the bones and offal left over from processing fish used for human consumption, while the larger percentage is manufactured from wild-caught, small marine fish; either unmanaged by-catch[1] or sometimes sustainable fish stocks.[2] It is powder or cake obtained by drying the fish or fish trimmings, often after cooking, and then grinding it. If the fish used is a fatty fish it is first pressed to extract most of the fish oil.[2][3]
