Abstract

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.
