Vegetable, livestock and agroindustrial products and byproducts: An alternative tilapia feeding

Abstract

In the culture of tilapia limited supply and high cost of fish meal have forced nutritionists to consider alternative sources of protein. Due to the importance of the products and by-products in fish feed, this paper aims to show the alternatives that have been used to partially or totally replace fish meal and soybean meal in tilapia growing. This paper showsthe maximum or optimal use of vegetable by-products for tilapia as cottonseed meal, sunflower, canola, soybean and Leucaena. It also deals with the inclusion with agro-industrial by-product such as corn, sorghum, coffee pulp, cocoa, wheat and citrus. The present study also deals with the use of aquatic plants such as Lemna and Azolla, single-celled plant protein source as antibiotics and probiotics. Finally, this paper also refers to animal by-products as silage, manure and earthworm usage. There is a high potential for using plant, livestock and agro-industrial by-products in fresh and processed food for the tilapia, but depending on the product, pretreatment to improve its balance of nutrients or eliminate anti-nutritional factors may be required.
