Where mushrooms are cultivated, a significant amount of mushroom residue is generated annually. This waste material is rich in crude protein, crude fat, and nitrogenous compounds. It also contains essential minerals such as calcium, phosphorus, potassium, and silicon, making it a highly nutritious byproduct. As a result, it can serve as an excellent feed supplement for fish farming.
The process of using mushroom dregs as fish feed involves several key steps. First, after the mushrooms are harvested, the residual material is collected and carefully screened to remove any foreign debris like mud clumps, stones, metal pieces, or broken glass. Once cleaned, the dregs are sun-dried to reduce moisture content and then ground into a fine powder using a grinding machine. This powder is then mixed into regular fish feed at a ratio of 20% to 30%. This not only helps in reducing feed costs but also enhances the nutritional value of the diet, promoting better growth and health in the fish.
Additionally, using mushroom residues as feed offers an environmentally friendly solution for waste management in the mushroom industry. By repurposing this organic material, farmers can minimize landfill use and contribute to sustainable aquaculture practices. Overall, integrating mushroom dregs into fish feed is a smart, cost-effective, and eco-conscious approach that benefits both the养殖户 (fish farmers) and the ecosystem.
