The present study was designed to assess the growth and production performance of common carp (Cyprinus carpio) fry reared at various stock rates in the pond of the BAPARD campus, Gopalganj from the 1^st of April till June the 15^th in 2022.  Six typical ponds (three treatments with two replications) were selected with a rectangular size of 10±0.25dec and an average depth of 1.52±0.03 meter. Three different stocking densities with two replications, T₁ (20,000 fry/dec), T₂ (22,500 fry/dec) and T₃ (25,000 fry/dec) were examined. Fry samples with initial length & weight of 0.30±0.05cm and 0.28±0.06g, respectively, were collected from Sonali Fisheries Hatchery, Kotalipara, Gopalganj. The survival rate of the stocking common carp was 53±0.15%, 51±0.12% and 50±0.20in T₁, T₂ and T₃, respectively. The weight gain of common carp recorded values of 1821.43±1.00, 1507.14±0.75 and 1239.29±0.89in T₁, T₂ and T₃ respectively. The daily weight gain (g/day) of common carp was recorded as 0.07±0.05, 0.50±0.04and 0.40±0.045in T₁, T₂ and T₃, respectively. The biomass gains (g) of common carp were 5.09±0.05, 4.22±0.06and 4.34±0.07in T₁, T₂ and T₃, respectively. The feed conversion ratio was evaluated to be 1.80±0.07, 2.15±0.05and 2.50±0.08in T₁, T₂ and T₃, respectively. The SGR in weight (%/day) of common carp was recorded as 3.94±0.03, 3.71±0.04and 3.70±0.05in T₁, T₂ and T₃, respectively. The condition factor (K) of common carp recorded values of 1.06±0.02, 1.04±0.04and 1.00±0.03in T₁, T₂ and T₃, respectively. The production (kg/dec.) of common carp registered values of 57.02±0.02, 50.87±0.82 and 46.29±0.50 in T₁, T₂ and T₃, respectively. The benefit-cost ratio (BCR, species) was significantly (P<0.05) higher in T₁ (1.46) than T₂ (1.27) and T₃ (1.05). The findings of this experiment showed that the lower stocking density produces high production with low expenditure.
