Catfish feeds are made up of major and minor ingredients combined in the right proportion to give required nutrient to fish that feed on them. Certain ingredients are major because they form the larger proportion of the feed – even up to ninety-six percent of the total feed ingredients. However, minor ingredients are needed in very small quantity in feed but their importance cannot be overlooked. Absence of feed ingredients needed in small quantity can reduce the efficiency of your feed to about fifty percent. Therefore, understanding of both major and minor ingredients is needed to prepare an efficient catfish feed.
