Fish Production in Cemented Masonry Tanks under Semi-static Water Conditions

Abstract

Two circular comonted masonry tanks. each of 113m aroa and 0.85 m depth. with fluctuating water levels, when utilised for fish culture. yielded a gross/net produ- tion of 2405.8/2057.2 Kg and 1560.0/1177.2 Kg/ha./year. Given only artificial feeding. Cirrhinus mrigala and Labco calbasu recorded appreciable growth. The prospects of fish production in masonry tanks and particularly ryots raising additional fish crops by diverting the flow of water to the fields through a dug-out earthen fish pond, thereby integrating fish culture with agriculture, have been indicated.
