K.MiahM. I.MirzaM.J. A.HabibM.A. B.9200369Nursery rearing of Puntius sarana (Ham.) was studied in relation to varying stocking density for a period of 6 weeks in earthen ponds. The experiment was performed in randomized block design with 3 treatments and each treatment had 3 reapplications. The ponds were stocked at the density of 0.7 (T1), 0.8 (T2) and 0.9 (T3) million individuals ha-1 and highest survival and growth performances of the fry was found in T1 Treatment in terms of length (L) and weight (g), where stocking density was 0.7 million ha-1 and a mixture of rice bran 40%, mustard oil cake 50% and fishmeal 10% were supplied. In T1 Treatment, the highest average growth was 1.50 mm day-1 (length) and 0.12±0.00 g day-1 (weight) and survival rate, specific growth rate and FCR were 62.9±1.69%, 17.65±0.02 and 1.05±0.04, respectively. Poor growth performance was observed in T3 treatment, where stocking density was high (0.9 million ha-1). The physico-chemical factors which included temperature, transparency, pH, dissolved oxygen, alkalinity, nitrate-nitrogen, nitrite-nitrogen, phosphate-phosphorus, ammonia-nitrogen, hardness and chlorophyll-a were found to be optimum level for fish culture. The physico-chemical factors, length and weight of fishes and plankton were recorded weekly.]]>DoF, Ministry of Fisheries and Livestock. Bangladesh,20022002Haque, M.Z., M.A. Rahman, N.
