Effects of different temperatures on growth and intestinal microbial composition of juvenile Eriocheir sinensis
With the global warming and the increase of various extreme weather events in recent years, there are more and more studies on the effects of temperature on crustaceans. However, only few studies explored the environmental factors that may affect the intestinal microorganisms of juvenile E. sinensis. The growth and development of juvenile E. sinensis is closely related to temperature, and the change of temperature will lead to changes in the composition of intestinal flora of juvenile E. sinensis, which has a great impact on the growth and survival of the host. Currently, no study has fully studied whether the growth difference is caused by the change in intestinal microflora due to the change in temperature. In this study, three different temperature groups were used to compare and analyze the growth and abundance of intestinal microflora of juvenile E. sinensis. The purpose of this study was to explore the effect of temperature on intestinal microorganisms, and evaluate the relationship between intestinal flora and growth. The results of this study can provide a reference basis for optimizing the breeding conditions of juvenile E. sinensis, promoting the healthy and rapid growth of juvenile crabs and preventing and diagnosing crab diseases.
