Summary: This study investigated the effects of dietary natural astaxanthin derived from Haematococcus pluvialis on the growth performance, pigmentation, digestion, antioxidant capacity, immunity, and response to air exposure stress of juvenile red swamp crayfish. The results showed that dietary astaxanthin significantly improved the survival rate and weight gain rate of juvenile crayfish. It also enhanced pigmentation and increased carotenoid content in the carapace, muscle, and ovaries. Astaxanthin supplementation increased the activity of digestive enzymes and antioxidant enzymes, and reduced oxidative stress markers in the crayfish. The optimal dietary natural astaxanthin content for juvenile red swamp crayfish was found to be between 63.55 to 84.40 mg kg-1.

Summary: This study investigated the changes in gut microbial community and immunity of red swamp crayfish under different nutritional states. Starvation increased the number and abundance of microbial species, while re-feeding restored them. Starvation disrupted the stability of the gut microbial community, while re-feeding helped restore the balance. Re-feeding also reversed the negative effects of starvation on immunity and gut health.

Summary: In this study, a 16-kDa protein homolog named Pc-E16 was identified in Procambarus clarkii. Pc-E16 was highly expressed in the intestine and its expression was significantly induced by lipopolysaccharides in hepatopancreas and hemocytes. Pc-E16 is involved in the innate immune response of P. clarkii.

Summary: This study analyzed the immunological effects of Salvia miltiorrhiza polysaccharides (SMP) on the hemocytes of Procambarus clarkii. The results showed that SMP treatment upregulated the activity of total superoxide dismutase (T-SOD), phenoloxidase (PO), and respiratory burst. Differential gene expression analysis revealed that SMP affected crustacean cellular immune-related signaling pathways. Furthermore, diets supplemented with SMP improved the cellular and humoral immunity of crayfish. This study provides molecular evidence for the immunopotentiator effects of plant polysaccharides in crustaceans.

Summary: Based on the previous studies, the adaptability of the red swamp crayfish to non-hyperthermal stress was investigated in terms of antioxidant capacity, immune function, HSP70 expression, and intestinal microbial changes. The results showed that the crayfish exhibited increased antioxidant capacity, immune-related enzymatic activities, and HSP70 expression under the non-hyperthermal stress temperature. The diversity and composition of the intestinal microbiota were also altered. These findings provide insights into the adaptive mechanisms of the crayfish in response to short-term non-hyperthermal stress.

Summary: Astaxanthin, an important antioxidant and nutraceutical compound, is widely used in dietary supplements and cosmetics. The refinery of astaxanthin from Haematococcus pluvialis is a growing industrial sector, as it can accumulate astaxanthin up to 5% of dry weight. Further research on production optimization and joint-production with lipids could make algal-derived astaxanthin more accessible for various applications.

Summary: This study investigated the characteristics of a dominant strain wx3 isolated from sick red swamp crayfish and analyzed the immune response of the crayfish under stress. The whole genome analysis confirmed that wx3 is the pathogen Aeromonas salmonicida subsp. Masoucida, which causes red swamp crayfish head rot. The study also found that wx3 is highly sensitive to certain antibiotics and that infected crayfish show a strong immune response.

Summary: For a long time, it was believed that invertebrates do not possess acquired immunity and mainly rely on innate immunity for protection against pathogen infection. However, recent studies have shown that invertebrates can exhibit specific immune priming after prior exposure to pathogens, suggesting the presence of immune memory. In this study, crayfish were preimmunized with a formalin-killed pathogen, which resulted in enhanced immune protection and increased expression of certain immune-related genes. These findings contribute to our understanding of the molecular mechanism underlying immune priming in invertebrates.

Summary: This study found that bacterial lipopolysaccharide (LPS) and deoxynivalenol (DON) in the aquatic environment have synergistic toxic effects on red swamp crayfish. Co-exposure to LPS and DON reduces the survival rate and causes histopathological changes in the hepatopancreas. These findings have implications for the development of crayfish aquaculture industry in China.

Summary: This study evaluated enzymatic rice protein (RP) and enzymatic fish paste (FP) as potential alternatives to fishmeal in industrial aquafeeds. Results showed that replacing 2.5% fishmeal with RP could improve the weight gain rate of fish, while growth was reduced when the replacement reached 7.5%. Moreover, a mixture of 5.0% FP and 5.0% RP could completely replace fishmeal, maintaining growth and promoting muscle development and antioxidant properties.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
