Performance of Amblypharyngodon mola with Barbodes gonionotus, Cyprinus carpio and Macrobrachium rosenbergii in rice-fish culture system

An experiment was conducted to assess the performance of mola (Amblyphmyngodonmola) in rice fish culture system with freshwater prawn Macrobrachium rosenbergii), Thaisilver barb (Bm·bades ganianotus) and common carp (Cyprinus cmpia) for a period of 4months at the Agronomy Field Laboratory, Bangladesh Agricultural University,Mymensingh, Bangladesh. Four treatments viz., treatment-I (T1) with A. mala and M.rosenbergii; treatmen t-II (T2) with A. mala, M. rosenbergii and B. gonianatus ; treatmentIII(T3) with A. mala, 1Vf. rosenbergii and C. cmpia, and treatment- IV (T4) as control(without fish) were used in triplicate. All treatments were equally fertilized with urea(200 kg/ha), TSP (150 kg/ha) and MP (75 kg/ha). The mean values of water qualityparameters viz., temperature, dissolved oxygen, pH, nitrate-nitrogen showed a verysmall variations among different treatments, but phosphate-phosphorus andchlorophyll-a were relatively higher in T4 without fish (i.e., control). The fishproduction of 480.5 kg/ha in T3 was significantly higher than that of 355.6 kg/ha T2 and223.8 kg/ha in T 1• The values of soil organic matter, total-nitrogen, phosphorus andpotassium at harvest were significantly (P<0.05) higher in the treatments with fishthan without fish, but pH did not show any significant differences. The yield of ricegrain and straw was also obtained significantly (P<0.05) higher in the treatments withfish. The increase in grain was higher over the control by 11.81%, 9.41% and 14.76%and that in straw was by 9.83%, 4.77% and 13.29% in Tl> T2, and T3 respectively.
