The traditional method of raising ducks on the surface of water not only contaminates the aquatic environment, but also causes meat ducks to expend excessive energy just moving around on the water. This hinders their growth and makes it inefficient to use fish ponds and floating nets for duck rearing. These issues can be effectively addressed with a more advanced and eco-friendly approach. This method is simple, cost-effective, and promotes ecological balance while significantly boosting the economic returns from duck farming. By using ducks directly in aquaculture, farmers can achieve dual benefits—raising ducks and improving fish production. Here are the key technical details:
1. **Constructing a Bamboo Shelter**
A bamboo house should be built next to the fish pond, with half of it extending into the water and the other half on land. A platform made of bamboo strips is installed at 40–50 cm above the ground, covered with long bamboo slats spaced 10 cm apart. A nylon woven mesh is added on top to ensure the ducks can walk comfortably while preventing injuries that might affect their market value. The floor is covered with straw for warmth and insulation. An adjustable window is installed for ventilation, and under the floor, there are channels and drains to prevent feed waste. Additionally, fluorescent lights are placed inside the bamboo structure for nighttime illumination.
2. **Ensuring Sufficient Water Supply**
A simple water tower is set up outside the bamboo shelter. Each time, about 3 tons of water can be stored. A basic pump is used to push water through pipes into the tank, ensuring a continuous supply of clean drinking water. The drinking trough can be made of bamboo or rough plastic pipes, with small holes for the ducks to drink from, allowing water to flow continuously.
3. **Feeding Requirements**
A balanced diet is essential. Feed should include rice, chopped rice, rice bran, sorghum, and corn, with a variety of ingredients to ensure nutrition. Green feeds should be provided regularly. The diet should contain 14% crude protein and 12.13 MJ/kg of metabolizable energy. Adding 10% sand helps improve digestion.
4. **Night Feeding**
Ducks should be fed in the morning, evening, and once at night. Feeding should be unlimited to support optimal growth.
5. **Appropriate Stocking Density**
Ducks should be raised at a density of 80–100 per acre. Their droppings, which contain 30% undigested nutrients, can be used as fish feed, promoting the growth of plankton and forming a sustainable ecological cycle.
6. **Disease Prevention**
Due to the high stocking density, regular disinfection of the nylon mesh and bamboo structures is crucial. Drinking troughs must be cleaned twice daily to maintain hygiene and reduce disease risk.
7. **Maintaining Feather Quality**
Twenty days before sale, ducks should be washed for 10 minutes each time to keep their feathers clean and white, enhancing their market appeal.
8. **Timely Harvesting**
When the survival rate of both fish and ducks exceeds 95%, and the ducks reach a weight of 2.5 kg, they can be sold. This system reduces the rearing period by 43 days compared to traditional methods, allowing for faster turnover and better profitability.
This integrated approach not only improves duck health and growth but also enhances the productivity of fish ponds, making it a smart and sustainable choice for modern farmers.
