EFFECTS OF STARVATION STRESS ON HEMOLYMPH PHYSIOLOGY AND INTESTINAL HEALTH OF PROCAMBARUS CLARKII

Procambarus clarkii originated from the south-central United States and northern Mexico. In the 1930s, it was introduced to China as a freshwater economic crustacean via Japan because of its good economic benefits and a characteristic industrial chain.As the consumption hotspot of P. clarkii to grow, fundamental researches on the cultivation of P. clarkii were incredibly important. At present, researchers carried out a large number of analysis on the effects of starvation on the physiology, endocrine, and digestive systems of crustacea To explore the effects of starvation stress on hemolymph physiological biochemical indexes, intestinal histology and intestinal flora of P. clarkii through histopathology, high-throughput sequencing and bioinformatics analysis techniques. P. clarkii was subjected to a 28-day starvation.nbsp;The results indicate that P. clarkii may adapt to the process of starvation metabolism by changing the energy material utilization pathways and the intestinal microbiological composition structure.
