Abstract:
The experiment was carried out simultaneously to compare the growth performance of Amblypharyngodon mola in rice fish culture system with Barbodes gonionotus and cyprinus carpio in farmer`s rice fields near to Bangladesh Agricultural University campus, Mymensingh for a period of 113 days from 12th August to 3rd December, 2002. Three treatments viz., T1 with A. mola and B. gonionotus, T2 with A. mola and C. carpio and T3 as control (without fish) were used in this study. Each treatment was provided with three replications. All the treatments were fertilized with urea (200 kg ha-1), TSP (150 kg ha-1) and MP (75 kg ha-1). With respect to cultural suitability, A. mola showed comparatively high growth rate and survival rate when it was stocked with C. carpio than with B. gonionotus. Among the three species A. mola showed the lowest growth rate and C. carpio showed the highest growth rate by average, net and percentage of increase. The production of fish were also recorded higher (576.27 kg ha-1) in the treatments stocked with A. mola and C. carpio than (298.91 kg ha-1) the treatment stocked with A. mola and B. gonionotus. However, the growth rate and survival rate of A. mola were always higher in treatment T1. Significantly (P<0.01) higher yield of grain and straw were obtained in the treatments with fish than without fish and they were found to increase over the control by 15.88-19.34% for grain and 12.78-15.34% for straw. The initial values (before rice transplantation) of soil pH, organic matter, total nitrogen, phosphorus and potassium contents did not show any significant difference among the treatments in most cases, but the final values (after harvest of rice and fish) of the same were recorded significantly higher in the treatments with fish than that of control (without fish) in most of the cases except pH.
