Dietary protein and energy requirements of Penaeus vannamei and the optimal protein to energy ratio (Texas A&M University. Libraries, 1995)The dietary protein requirement of penaeid shrimp has been investigated under different experimental conditions. The recommended protein levels reported for each species have not been based on energy density of the diet ...
