This invention discloses a method for preparing and applying a low-chitin enzymatic hydrolysed cricket feed based on Trichoderma and copepod autolysins, belonging to the field of aquaculture technology. This invention employs a combined enzymatic hydrolysis method using Trichoderma activation and copepod autolysins, which not only significantly reduces the chitin content in the cricket feed (to below 1%), but also optimizes the nutritional composition of the feed by introducing marine functional proteins from copepods. This not only replaces fishmeal in feed but also contributes to the growth and health of aquatic animals.

This invention provides a feed enhancer specifically for low-salinity aquaculture of redclaw crayfish and its application. It belongs to the field of feed additive technology. This feed enhancer for low-salinity aquaculture of redclaw crayfish combines plant polysaccharides and probiotics in a synergistic manner, effectively leveraging the efficacy of both polysaccharides and probiotics. The synergistic effect significantly improves the redclaw crayfish's tolerance to low-salinity environments. Compared to traditional freshwater feed aquaculture of redclaw crayfish, it solves the problems of slow growth and high mortality rates, while also increasing yield, reducing the feed conversion ratio, and maximizing aquaculture efficiency. This provides technical support for the development of redclaw crayfish aquaculture in low-salinity areas of Guangxi and also enriches the varieties of marine aquaculture.
