Abstract

A comparative study on monoculture of Puntius gonionotus and mixed culture of Puntius gonionotus and Cyprinus carpio was conducted in 6 ditches of 400 m2 for five months. There were two treatments and each ditch was stocked with a 15000 nos. ha‾1 of fish. A significantly higher (p<0.05) total production (2002.45 kg ha‾1/5 months) was obtained in the mixed culture system (T2) than that of the production (1556.86 kg ha‾1/5 months) of monoculture system (T1). The net benefit of monoculture and mixed culture system was Tk. 49,943.00 and Tk. 56,514.00 respectively.
