The present invention relates to a feedstuff for carnivorous freshwater fish farming and a manufacturing method thereof. The feedstuff for carnivorous freshwater fish farming is manufactured by mixing 55-65 wt% of microorganism fermented rice bran, 25-35 wt% Ptecticus tenebrifer larva, 5-15 wt% of casts of Ptecticus tenebrifer larva; crushing the mixture; and adding effective microorganisms into the mixture before fermenting. The feedstuff for carnivorous freshwater fish farming is well digestible for carnivorous freshwater fish such as loach by mixing the microorganism fermented rice bran and Ptecticus tenebrifer, saves feed costs by using the larva of Ptecticus tenebrifer which is prolific, high-protein, and unharmful, prevents decaying and bad smells, maintains an eco-friendly farm using microorganism fermented raw materials even in case that the feedstuff is not fed on time, and minimizes water pollution. Moreover, the present invention improves the nutritive condition and the reproduction rates of the carnivorous freshwater fish by feeding the carnivorous freshwater fish with high-protein feed. |
