Comparative Studies on the Nutritional Fitness of some Selected Cichlids Sampled from OBA Reservoir, South Western Nigeria

Ogundiran MA* and Ayandiran TA

Comparative analysis of the nutrient fitness of some selected wild fish species from Oba Reservoir were carried out using standard methods. Seven different species (Tilapia guinnensis, Tilapia dageti, Tilapia zilli, Oreochromis aureus, Sarotherodon galilaeus, Oreochromis niloticus and Hepsetus odoe) were sampled and analyzed for the period of twelve months. The results of the proximate composition showed that all the sampled fish species contain adequate amount of protein, moisture, lipid, ash and carbohydrates with a significant difference (p<0.05) in ash content and crude protein. Also, the results of the minerals contents indicated that sampled species contain an appreciable amount of zinc, iron, copper, calcium, sodium, potassium and manganese, with a significant difference in protein, zinc, calcium and iron. Therefore, further studies should focus on the improving the quality of the water body in order to enhance the overall nutritional composition of the residing organisms.
