Dietary protein quality and proper protein to energy ratios: a bioeconomic approach in aquaculture feeding practices

ABSTRACT Supplementing high levels of dietary crude protein in the absence of amino acid balance and enough energy in fish diets may results in reduced growth, improper feed intake and poor protein utilization efficiency coupled with unviable feed costs and adverse environmental effects due to high...
