Animal Origin Fish Feed Ingredients

Animal origin fish feed ingredients are obtained from different mollusks, silkworm, poultry, cattle and fish mainly. These feed ingredients are applied by targeting carnivorous culture species. Some ingredients like fish viscera, cattle viscera are applied directly into the culture water body and some are applied after some sort of preliminary processing. Animal origin feed ingredients contains more protein in comparison to those ingredients of plant origin. Most of the animal origin fish feed ingredients are considered as protein supplements (i.e. contains more than 20% protein).

Some common animal origin fish feed ingredients:

Some common animal origin fish feed ingredients are- Fish meal, fish silage, bone meal, cattle viscera, poultry viscera, fish viscera, oyster shell meal, silkworm pupae, blood meal, crab meal, frog waste, snail muscle etc. However, some common animal origin fish feed ingredients in Bangladesh are described here-
