Production of Thai sharpunti (Puntius gonionotus Bleeker) in polyculture with carps using low-cost feed

The effectiveness of duckweed and rice bran as a low cost supplementary feed was compared through a six months production trial of rajpunti (Barbodes gonionotus) with carps. Six earthen ponds of 360 m² each were used for the trial. Three ponds received duckweed, while the other three received rice bran as supplementary feed. Fish biomass after six months of rearing increased to an average of 2,056 kg/ha in ponds which received duckweed and 2,056 kg/ha in rice bran treated ponds. The net profit with duckweed and rice bran worked out to Tk. 69.752 and Tk. 73.480 kg/ha, respectively. This study revealed that duckweed is a low cost supplementary feed, particularly for farmers with limited income.
