Abstract: This comparative study on growth of Indian air-breathing fishes, Clarias batrachus (Linn.) and Anabas testudineus (Bloch) was performed in 42-L aquariums with water recirculation system for 60 days. Triplicate groups of fingerlings each were fed four isonitrogenous compound diets, at 5% of wet body weight basis. Fishmeal in control diet was 100% replaced by poultry wastes (skin, intestine and viscera) in three experimental diets respectively, though other ingredients remained same. Effects of poultry wastes were judged on the basis of comparative growth performances (S.G.R%, F.C.R, P.E.R) of both fish types. Proximate composition confirms, nutrients in poultry viscera are superior to fishmeal. P.E.R, S.G.R%, weight gain and survival rate of both fish types were recorded highest with poultry viscera based compound diet, which are significantly different from control diet. So, this treatment is preferred and is recommended, for both fish types, because the use of poultry viscera as a nutritious feed supplement helps to reduce feed cost ensuring optimal fish growth, and stimulate waste management also.
