Abstract: The organic carbon stocks of fresh Colisa sota (Hamilton), Anabas testudineus (Bloch), Channa punctatus (Bloch), Osteobrama belangeri (Valencienes), Amblypharyngodon mola (Hamilton), Esomus danricus (Hamilton) and Puntius sophore (Hamilton) were determined. The varied organic carbon content was recorded in the studied fish species. From the study revealed that organic carbon content was highest in the O. belangeri (56.20±0.04%) and was the lowest (39.46±0.04%) in the A. testudineus. The fish species of the study area is a good reservoir of organic carbon so has a good capacity to sequester organic carbon from the water and atmosphere. Conservation of fish species may help to sequester more organic carbon so that economic benefit for the country and environmental benefit in the international arena are possible from the study area.
