Fish feed is the most expensive input in aquaculture operations. Much of the high cost of feed arises from extensive reliance on protein sources- fishmeal and shrimp meal. The shortage and high cost of pelleted feed severely constrained the development of low cost aquaculture systems suitable for small-scale farmers in the developing countries.
Hence, there is a need to assess the potential of non-conventional raw ingredients such as the sweet potato peels. It would therefore be more economical to utilise plant protein in fish feeding than high cost animal protein materials.
