Feasibility of culturing pengba (Osteobrama belangeri) as a candidate species in polyculture along with other carps in net pen enclosure was studied in Takmu lake, Manipur. A net pen measuring 0.1 ha was constructed using nylon net supported by bamboo poles. The average length and weight of stocked fingerlings (@5 no. m-2) were as follows: pengba (9.4 cm, 10.6 g), Labeo catla (16.1 cm, 39.0 g), Labeo rohita (14.8 cm, 38.6 g), Cirrhinus mrigala (16.2 cm, 41.9 g), Hypophthalmichthys molitrix (14.2 cm, 30.3 g), Ctenopharyngodon idella (22.4 cm, 115.2 g) and Cyprinus carpio (14.8 cm, 55.1 g). Fishes were fed pelleted feed (23.4% crude protein) @ 5% of body weight twice-a-day for 180 days. Highest growth (in terms of weight gain % and specific growth rate) was recorded in pengba followed by C. idella, L. catla, C. mrigala, L. rohita, C. carpio and H. molitrix. The pen aquaculture system was also found to be economically viable with a benefit-cost ratio of 1.37. In conclusion, net pen aquaculture of pengba along with other carps is economically viable and technically feasible in floodplain wetlands of Manipur.
