Abstract: Efficacy of different stocking density on the growth and survival of striped dwarf catfish, Mystus vittatus fingerlings in nursery ponds has been evaluated with three stocking density treatments (T) viz., T1 - 8,000 fry dec-1, T2 - 12,000 fry dec-1and T3 - 16,000 fry dec-1. After seven weeks of rearing, survival of fingerlings was the highest (65.50±0.49%) in T1 which was significantly higher than those of T2 (55.50±0.21%) and T3 (49.00±0.70%) and also significant difference in final length (3.34-6.89cm) and final weight (3.32-7.92g) among the three treatments were observed. Physico-chemical variables of water and plankton abundance of different treatments were recorded and discussed.
