The mouth brooding Cichilid fish Oreochromis mossambicus (p) is found to be omnivorous and prolific breeder. The present study is on the assessment of condition of the male fish Oreochromis mossambicus from Daroji water tank, considering gonadosomatic (GSI) and hepatosomatic (HSI) indices, Fulton’s condition factor (K), somatic condition factor (KS), in relation to length and body weight. Ten specimens of male Oreochromis mossambicus were randomly selected every month from June to December 2016 for the assessment. The females and males can be identified on the morphological basis. Such studies are needed for the fish to understand the health condition of the female and male fish separately in an aquatic body for their survival, growth and breeding activities. The K values of the male fish during breeding period from June to December 2016 indicates that as the length and body weight increases the K values also increase. The KS values exhibit fluctuations in different length and body weight. However, as the length and body weight increases, the KS values also increase. The GSI increases as the length and body weight increases. The HSI exhibits a different trend of values as the gonad weight increases the liver weight decreases and as the liver weight increases the gonad weight reduces and similarly the HSI values are found. The study indicates that the condition of male fish improves as the length and body weight increases with a inverse relationship of GSI and HSI and thus indicating that the fish is thriving well in the aquatic body.
