Proximate compositions of some fish species and heavy metal concentrations in Surface water from Oguta Lake

Fish is one of the essential foods necessary for growth and tissue repairs in animals and humans in particular. This work focused on the study of chemical composition of various fish species namely tilapia, eel, cat and channa fish as well as heavy metal concentration in surface water from Oguta Lake. The different species of fish were caught with standard fishing nets and analysed for moisture, protein, ash, lipid and carbohydrate contents. The results of the analysis showed highest moisture content of 75.95+0.005 in Tilapia, highest protein content of 46.25+0.005 in Channa, highest ash content of 4.00+0.005 in Eel, highest lipid content of 8.25+0.006 in Channa and highest carbohydrate content of 7.36+0.005 in Eel fish. Channa fish is therefore recommended for its high protein and lipid contents. The result of the Oguta lake surface water showed higher concentrations of lead and mercury than recommended by the Regulatory Bodies WHO, NAFDAC and SON.
