Performances of fingerling size and water area was studied. Seven species of fish included25% of Hypophthalmichthys molitrix, 15% of Gada catla, 20% of Labeo rohita, 10% ofCirrhinus mrigala, 10% of Ctenophyringodon idella and 20% of Macrobrachiumrosenbergii were stocked at the rate of 8,000 individual/ha along Barbodes gonionoms at6.0g weight size with a stocking density of 2,000 indl./ ha.Survival of all species was in the range of 39.9 to 96.3% except M. rosenbergii Thehighest survival was obtained from L. rohita (96.3%) followed by C mrigala (96.0 %)., B.gonionotus (92.3%), C idella (90.6%), H. molitrix (84.0%), C cada (81.7%) respectively.While the survival of M. rosenbergiiwas 13.1%. The highest production of 4912 kg/ha/yrwas obtained from the bigger ponds (0.4 ha) stocked with 20-32g size of fingerlings, whilelowest production (3123 kg/ha/yr) from small pond (0.1 ha) stocked with 3-10 gfingerlings. Economic analysis shows the highest net profit in bigger ponds stocked withbigger fish seed.Journal
