Interpretive Summary:

Technical Abstract: This study in an outdoor biofloc technology production system evaluated impacts on fish production indices, common microbial off-flavors, and water quality dynamics for hybrid tilapia fed diets formulated to contain 22.5%, 27.7%, and 32.3% digestible protein (DP) and 6% lipid. Results of this study suggest that by using ideal protein theory to formulate diets supplemented with the first four limiting amino acids (Lys, Met, Thr, Ile) digestible protein can be reduced from 32.3% to 27.7% without adversely affecting hybrid tilapia productivity indices.
