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

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 (raw, chemically treated with hydrogen peroxide and fermented PTSW) while diet with fish meal alone served as the reference feed. The fish were characterized by mean final weight; percent weight gain, feed conversion ratio 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. Hence, replacement of fishmeal with PTSW will be a best approach to ease out solid waste disposal problem for environmentalist and also beneficial as an economic feed in aquaculture.
