How to establish a fish, grass, and pig integrated fish farming model that produces 250 kg of fish per 0.07 hectares of pond? According to available data, achieving this yield requires approximately 10,000 kg of pig manure and 10,000 kg of base fertilizer. This means a total of 20,000 kg of pig manure is needed for both base and top dressing, which translates into needing about 8 to 10 pigs per 0.07 hectares of water.
To support the livestock, around 0.028 hectares of land is required to grow 6,300 kg of green feed such as ryegrass and Sudan grass. For instance, if 70 kg of green feed can be produced from 100 kg of swine manure, then 9,000 kg of manure would be needed to produce 6,300 kg of feed. Assuming each pig produces 2,250 kg of manure, that would mean 4 pigs are sufficient to meet the feed requirements. Each pig needs about 875 kg of green feed, so four pigs would require a total of 3,500 kg of feed, which corresponds to about 0.015 hectares of land.
Taking all this into account, the pig, grass, and fish system that yields 250 kg of fish per 0.07 hectares requires 0.043 hectares of feed land and 4 pigs per pond area. Establishing this family-based integrated fish farming model allows for an annual production of 300 kg of pork and 250 kg of fish. This model not only maximizes land use but also promotes sustainable agriculture by recycling nutrients between livestock and aquaculture. It’s a practical approach for small-scale farmers looking to increase productivity while maintaining environmental balance.
