Balbeer Singh, Dr. Dayanand Pandey

The fish production plays a significant role in the human economy. India has vast potential for development of inland fisheries. In the present study an attempt has been made to evaluate the fish productivity of Gangapur tank located in Rewa district. The Gross Primary Productivity of the tank followed a more or less similar trend of fluctuations and also exhibited an increasing trend through the rainy season towards summer season with distinct peaks during three years of study and lower values were observed during rainy season. It was clear that the Gross Primary Productivity changing significantly with seasons. Net primary productivity of Gangapur tank followed a more or less similar trend of fluctuations in all four stations exhibited an increasing trend towards a rainy season and winter season with distinct peaks while lower values of net primary productivity observed during rainy season. Community Respiration observation in the tank followed a similar trend of oscillation in all four stations lower values during winter season throughout the study period and exhibiting an increasing trend toward summer and rainy season.
