A rice-fish culture experiment with four treatments viz., T 1 with Amblyphmyngadan malaalone, T 2 with A. mala and Barbodes gonionotus, T3 with A. mala and Cyprinis carpio and T4as control (without fish) was carried out in the rice fields during April throughAugust1999. The recovery rate of A. mala were 42%, 37% and 42% in treatments 1, 2 and 3respectively and the same recorded for B. gonionotus and C. cmpio were 62% and 55%respectively. Among the three species of fish, B. gonionotus showed much higher recoveryrate than both of A. mala and C. carpio. The production of A. nwla was 12.50 kg/ha/3months in monoculture, and 7.92 kglha/3 months and 8.86 kglha/3 months incombination with B. gonionotus and C. carpio, respectively. The production of B.gonionotus in T2 was 169.29 kg/ha/3 months and C. cmpio in T 3 was 252.92 kg/ha/3months. The total fish production was 12.50 kg/ha/3 months, 175.21 kg/ha/3 months and261.88 kg/ha/3 months in Tp T2 and T3, respectively. The highest yields of rice grain(5.78 ton/ha) and straw (7.83 ton/ha) were recorded in T3 and the lowest of the same wasin T4 (grain 4.96 ton/ha and straw 6.62 ton/ha). Rice yield increased by about 12.10% inT1, 13.30% in T2 and 16.33% in T3 in context to T4, rice-alone culture. The resultsdemonstrated that the culture of fish in rice fields had profound beneficial impact on theproduction of rice grain and straw.Journal
