Fresh tofu dregs contain some special substances, which will affect the digestion and absorption of protein by fish protease. At the same time, once deterioration occurs, it is easy to cause fish poisoning and death. Therefore, it is generally necessary to ferment it before it can be used for feeding. The fermentation process can ensure that harmful bacteria are eliminated, and at the same time, it can improve its nutrition, which is easier for fish to absorb after eating.
