Rice cum fish culture
- 2. Introduction • Rice-Fish Culture Systems Based on the land characteristics and source of water there are two different systems of rice-fish culture. • 1. Concurrent system- Rice and fish are cultured simultaneously • 2. Alternate system - Fish is cultured after harvesting of rice • There is also another system where rice and fish culture started at the same time but fish culture continues for the next season after harvest of rice.
- 3. Rice varieties used for rice cum fish culture system • The deep water rice varieties chosen for different states are • PLA-2 ( Andhra Pradesh ) • IB-1, IB-2 , AR-1, 353-146 ( Assam ) , • BR-14, Jisurya ( Punjab ) • AR 61-25B, PTB-16 ( Kerala ) • TNR-1, TNR 2 (Tamil nadu) • Jalamagan (Uttar Pradesh) • Jaladhi-1, Jaladhi-2 (West Bengal)

- 6. Steps for cultivation Land selection Soil Preparation Preparing paddy seed Soil preparation to sow seedling
- 7. Transplanting seedling Fertilizer application Weeding Irrigation Pest control Paddy harvest
- 8. Steps for Fish culture Preparation of small pond/ditch: 15-20 days after planting paddy seedling, lime should be applied in the small pond/ditch in rice field at a rate of 1kg/decimal. Stocking of fish fry: 25-30 days after planting paddy, fish fry is stocked in the small pond. The density of fry stocking is 15-20 pieces of 4-6” fingerling per decimal. .
- 9. Post-stocking management: Fingerlings are kept in the small pond up to 10-15 days after stocking. Here they are fed at a rate of 4-5% of total biomass. After 15 days the fry roam inside the paddy field where it also feeds. At this stage there must be at least 8 -10” water in the field. Sometimes supplementary feed is given at the rate of 1-2% of total fish biomass
- 10. Harvest Gears use for harvesting fishes. It is simple bamboo made basket called cane. The fish culture for the period of 3-4 months in rice field, a production of 200-300 Kgs/ha achieved and while fish grown for the period of 5-6 months; 400-500Kgs/ha yield Normally fish harvesting before rice harvest
- 11. Benefits rice cum fish culture system Improves the soil fertility & soil health. Increasing economic yield per unit area. Reduction in production costs. Decreases farm input requirements. Multiple income sources. Family income support. Efficient utilization of family labor. Enhance employment generation. Pollution free environment. Recycling of resources. Improves the status & livelihood of the farmer.
- 12. Drawbacks Use of agrochemicals is often not feasible Maintaining high water level may not be always possible, considering the size and growth of fish. Fish like grass carp may feed on rice seedling Fish like common carp and tilapia may uproot the rice seedlings
