Raw Materials for Aquafeeds

Common basic raw materials to the manufacture of most aquafeeds are similar to those employed in the manufacture of other types of animal feeds. However, it should be noticed that aquafeeds should avoid the use of high levels of plant or vegetable fibers and carbohydrates which are poorly digested and transformed by fishes. Raw materials for aquafeeds include cereals (maize, wheat, barley, rice, oat etc.), cereal by-products (wheat flour, corn bran, wheat bran etc.), meat meal, fish meal, shrimp meal, squid meal, blood meal, poultry by-product meal, (full fat) soybean meal, other vegetable protein meals, fats and oils, vitamin and mineral premix, salt, stabilizers and binders etc.

extruded aquafeed and raw materials

The major components of aquafeeds are protein (plant protein, animal protein and single cell protein), starch (sinking aquafeed consists more than 10% and floating aquafeed consists more than 20%), crude fat, raw fiber, crude ash and micronutrients.
