Abstract

A 150 days study was conducted to evaluate the growth and production of fishes at different species compositions in polyculture using tilapia (Oreochromis niloticus), catla (Catla catla), rohu (Labeo rohita), mrigal (Cirrhinus cirrhosus) at Jamalpur Sadar upazila under Jamalpur district in Bangladesh from April to August, 2017. There treatments are following stocking densities: T1 (250 individuals) T2 (165 individuals) T3 (135 individuals). The average initial weight of fish in different treatments were of tilapia, catla, rohu, and mrigal were 48.5 g, 95.5 g, 85.3 g, and 83.4 g respectively. The mean final weight of tilapia, catla, rohu, and mrigal were 405.53 g, 256.9 g, 286.07 g, and 290.83 g respectively. Present study showed the production of tilapia was the highest among the total production of fishes. There was higher mortality with the increased in density. The highest weight gain found in 135 individual/33 decimal/150 days culture. Among the three treatments the highest production of fish was recorded in T2 (1845.156 kg/33 dec/150 days) which was subsequently higher followed by the production of T1 (1783.581 kg/33 dec/150 days) and T3 (1461.296 kg/33 dec/150 days). In this study the highest production was achieved at the modest density indicate that stocking density not more than 165 individual/decimal can be fruitful for the tilapia-carp poly-culture. Farther investigation with tilapia and other than carp species could be done to assess the influence of species assemblage in poly-culture system in pond aquaculture.
