IWAMOTO Izumi Mahfuzul Haque M. 3 2008 3 3 Bangladesh has 10.4 million hectare of rice field which can be used for fish culture either in con-current or alternate with paddy production and such system of paddy and fish improves productivity and profitability. The present study was carried out to investigate the economic performance of fish based farming systems such as: Alternate-Rice-Fish (A-R-F), Rice-Cum-Fish (R-C-F) and Only-Rice-Farming (O-R-F). A total of 90 farmers were selected randomly where 30 from each of the farming systems for this study. Total return was highest for A-R-F farming than R-C-F and O-R-F which was calculated Tk.123,300, Tk.62,000 and Tk.31,725, respectively and the total cost also higher for A-R-F farming (Tk.42,599) than R-C-F (Tk.28,525) and O-R-F (Tk.19,569). Net return was also higher for A-R-F farming (Tk.80,701) than R-C-F (Tk.33,475) and O-R-F (Tk.12,156). To compare the net return of A-R-F farming was more than two times higher than the R-C-F farming and more than six times higher than the O-R-F and the net return for R-C-F farming was more than two times higher than the O-R-F farmers. It means that the net return ratio for A-R-F farming is quite high compared to R-C-F and O-R-F farmers and the R-C-F farming is more profitable than the O-R-F. The high profitability of A-R-F and R-C-F farming shown the good performance of fish based farming systems.
