He advised to stock, cyprinus (common carp), katla, and mixed ( rohu, katla, mrigal). of fingerlings stocked in pond per 1 hectare (2.4 acres) = 8000 to10,000. Age or growth stage of the fish: Fish at early stage of their life have higher metabolic rates and hence their growth rate is fast at this early stage. It is commonly found in tropical and temperate zones. He plans collaborating his agriculture, horticulture and farming knowledge into a subject of help to all those who wish grow crops, venture into farming or gardening. Although, many fish species carry high levels of the metal mercury, Rohu fish is listed among the fishes with low level of mercury chiefly because of the environment that are found. No. Trucks and air transport have been used according to the distances. Generally, 1 kilogram weight of fish can be more sold in the market. Reddy et al. When fish density is high competition for food becomes important. Growth in natural waters is influenced by food availability, feeding intensity and the reproductive cycle and under culture condition is determined by pond size, stocking density and size at stocking.
