Nutritional Evaluation of Animal Fleshing as a Fish Meal Replacer in Labeo rohita

Abstract

The present study explores the unexploited application of abundantly available proteinaceous solid waste material, animal fleshing (PTSW) from tannery as a feed protein source for fish cultures. Growth profile study of Labeo rohita, was conducted for 8 weeks to assess the effects of diets supplemented with PTSW. Experimental diets includes differentially processed PTSW while diet with fish meal alone served as the reference feed. The fish were characterized by mean final weight, percentage weight gain, FCR, and survival rate. The study concluded that there were no significant differences (p<0.05) in the characteristics of fish cultures fed on replacement diets.
