Integrated fish-rice farming, also known as rice-fish farming, is a sustainable and eco-friendly method of agriculture that combines fish farming with rice cultivation in the same field. This method of farming has numerous benefits such as increased crop productivity, higher fish production, and better utilization of natural resources. Here are the steps to start an integrated fish-rice farming system:
1. Selection of the site: The site for integrated fish-rice farming should be selected based on its soil quality, water availability, and accessibility to the market. The soil should be fertile with good water retention capacity, and the site should have a reliable source of water supply.
2. Construction of the pond: A pond is constructed in the field, with a depth of at least 1.5 meters and an area of 1-2% of the total field area. The pond should be dug before the rice cultivation season, so that the soil can settle before the planting of rice.
3. Preparation of the rice field: The rice field is prepared for cultivation by plowing, harrowing, and leveling the soil. The field is flooded with water to a depth of about 10 cm.
4. Stocking the pond: After the pond is constructed, it is stocked with fish species that are compatible with rice cultivation. Tilapia, carp, and catfish are commonly used in integrated fish-rice farming. The number of fish stocked should be based on the pond size and the desired fish density.
5. Rice transplantation: Rice seedlings are transplanted into the field after about two weeks of flooding. The rice variety chosen should have a short duration and be compatible with the fish species selected.
6. Feeding the fish: Fish feed is added to the pond once or twice a day, depending on the fish species and their feeding habits. The fish feed can be a combination of commercial feed and organic feed such as rice bran, fish meal, or vegetable waste.
7. Harvesting: The rice is harvested after the required maturity period, and the fish are harvested at the same time. The harvested fish can be sold in the market, consumed by the farmer, or used as fertilizer for the next rice crop.
Benefits of integrated fish-rice farming:
Increased productivity: The combination of fish and rice cultivation increases the productivity of the land. The fish provide organic fertilizer for the rice plants, which leads to higher crop yields.
a.Higher income: The farmer can earn a higher income from both the fish and the rice crops.
b.Reduced environmental impact: The integrated fish-rice farming system reduces the use of chemical fertilizers and pesticides, which has a positive impact on the environment.
c. Efficient use of resources: The fish feed on the pests and weeds in the rice field, reducing the need for manual weeding and pesticide use.
d. Diversification of income: The farmer has two sources of income from the same land, reducing the risk of crop failure or market fluctuations.
Overall, integrated fish-rice farming is a sustainable and profitable method of agriculture that can help to address food security, poverty, and environmental challenges.
