Fermented fish-offal (FO) meal was used as a protein supplement to replace fishmeal (FM) in the formulation of experimental diets for the Indian minor carp Labeo bata. The two supplementary diets, one containing 25% FM plus 25% FO and the other containing 20% FM and 30% FO, showed significantly higher digestibility, growth, and protein deposition than the reference diet containing 40% FM. Partial budgeting of diet formulation and net return revealed that 50% replacement of FM by fermented fish-offal meal rendered a total positive benefit of 134% as compared with the reference diet.
