Background: The worldly fish meal is utilized as a rich source of protein in animal feed formulation. The high price and curtly supply of fish meal encouraged us to find some indigenous informal sources of protein and energy for economical and desirable feed preparation. Materials and Methods: A profiled biochemical analysis of poultry by-products such as chicken offal excluding feathers and skin, head and neck, internal (chicken viscera), and two local trash fishes with high breeding and growth rate were analyzed to find nutritional value and low processing cost. Results: The desirable protein and energy content was determined in chicken head and neck whereas the lowest were found in chicken feet. In chicken internals and chicken composite meal, the protein and energy content was 46.4532%, 3484 Cal/kg and 44.6397%, 2705 Cal/kg respectively. The protein and energy level of karo dayo (Oreochromis mosumbicus) was 55.85 %, 3236 Cal/kg while kari mundhi (Channa punctatus) possess 52.97%, 2705 Cal/kg. The aflatoxin level was found below the threshold level and these ingredients are safe for feed preparation and utilization. Conclusion: The nutritional value of these chickens byproducts and local trash fish confers as a good source of protein and energy. These could be used as a partial or complete replacement of existing conventional protein and energy sources in fish feed formulation while these ingredients are very low cost and easily available to fish growers.
