Abstract: A study was carried out during the Aman season (September-Dcember) in the south-west coastal paddy fields of Bangladesh to understand the culture suitability and production potential of two exotic fish species, namely Puntius gonionotus and Cyprinus carpio in rice fish integrated culture system. Twelve paddy plots with size ranges from 1300-27000m2 were stocked with fish at a density of 4930 /ha for mono & mixed culture (50+50%). After 50 days of rearing production rate of fish from monoculture of Puntius gonionotus (T1), mixed culture of Puntius gonionotus1 and Cyprinus carpio (T2) and monculture culture of Cyprinus carpio (T3) was found 280.12, 330.40 (119.64+210.76 kg) and 279.78 kg ha-1, respectively. No significant variation in fish production was observed between T1 and T3. But compare to other treatments significant higher production of fish was obtained from T2. However, for rice production a significant lower production (3.14 ton h-1) was obtained for T3 compare to other two treatments, while higher rate of rice production (3.85ton/h) was recorded for T1. For control plot (T4) the production rate of rice was 3.40 ton h-1. In the study, no negative correlation was found for the integration of fish with rice culture.
