POTENTIAL OF WASTE-BASED ANIMAL PROTEIN FOR FISH FEED

Aquaculture

The growth and survival of farmed fish are significantly influenced by their diet. Fish feed must be formulated to meet the demands of fish and must have a full nutritional profile, be simple for fish to digest, and not include any dangerous ingredients (anti-nutrients). Since fish meal has an animal protein content of 60–80% and an 80–90% feed digestibility, it is frequently used to produce feed. Fish meal is exceedingly hard to come by and still depends on imported ingredients. Use of waste products from various agrocomplex activities can serve as a substitute source of protein for fish feed ingredients. The amount of waste produced by livestock and fishing operations is still relatively considerable (20–30%). Solid waste from fishing activities includes fish parts from the canning and smoking industries, as well as scales and gills. Fish meal cannot entirely be replaced as a source of animal protein by the use of animal protein sources derived from waste. In order to treat waste as ingredients for fish feed, this study will examine a number of sources of animal protein.
