Feeding fish directly with fresh pig manure can be an effective and cost-efficient method. Since the manure is newly discharged, it contains a high concentration of nutrients that are easily absorbed by the fish. This approach is convenient and doesn't require any special fermentation tanks, which helps lower overall costs. Additionally, the utilization rate of nutrients is quite high. Unlike fermented manure, fresh pig manure doesn’t spoil quickly, and it helps fertilize the water more rapidly.
When feeding fish with fresh pig manure, it’s recommended to use the feces from 3-4 pigs for every mu (approximately 667 square meters) of pond surface. The manure can be directly scattered into the water, and the amount should be appropriate for daily consumption. It's important to feed regularly, in small portions each day. During hot weather, avoid overfeeding at once, and if there are thunderstorms or extreme heat, it’s best to stop feeding temporarily.
In addition, maintaining good water quality is essential. Fresh pig manure can make the pond water more acidic, so it’s advisable to monitor the pH level. If needed, adding around 30-40 kg of lime water across the entire pond surface can help neutralize the acidity and improve the overall water conditions. Regular checks on the pond’s health are recommended to ensure optimal fish growth and prevent potential issues.
