Fish meal powder

Fish meal is a commercial product mostly made from fish that are not used for human consumption; fishmeal is generally used to feed farm animals in an agricultural setting, e.g., pigs, poultry, and farmed fish.^[1] Because it is calorically dense and cheap to produce, fishmeal has played a critical role in the growth of factory farms and the number of farm animals it is possible to breed and feed.

Fishmeal is made from the bones and offal left over from fish caught by commercial fisheries. The vast majority of the fish from which fishmeal is manufactured are not used for human consumption; rather, fishmeal is generally manufactured from by-catch.^[2][1]

Fishmeal takes the form of powder or cake. This form is obtained by drying the fish or fish trimmings, and then grinding it. If the fish used is a fatty fish it is first pressed to extract most of the fish oil.^[1][3]
