Summary: The gut microbiome is important for the immune system of both invertebrates and vertebrates. Pre and pro-biotics can enhance the shrimp immune system by increasing the activity of certain enzymes. Changes in the host immune system during viral infection can affect the gut microbiome and potentially lead to other infections.

Summary: The study found that coumarin can enhance the immunity of Cherax quadricarinatus, reduce the number of WSSV infections, and delay the infection process. Coumarin also has a positive effect on important immune parameters such as THC, ACP activity, SOD activity, lysozyme activity, and PO activity.

Summary: The study showed that the pathogens VP and WSSV significantly reduced hemocyte counts and increased glucose and serotonin levels in the hemolymph of black tiger shrimp. These pathogenic treatments altered the expression pattern of candidate genes and affected the physiological and biochemical parameters, resulting in negative impacts on growth and mortality of the experimental shrimps.

Summary: Investigation into lipid metabolism shifts in shrimp infected with white spot syndrome virus shows how the virus controls host metabolism to create favorable conditions for its replication. The virus induces lipolysis during its replication stage to provide material and energy, and triggers lipogenesis during the late stage to facilitate virion morphogenesis. The study also reveals changes in lipid droplets and fatty acid release in infected cells. This research demonstrates that white spot syndrome virus modulates lipid metabolism at different stages to support replication.

Summary: This study investigated the intestinal microbiota of healthy crayfish, WSSV-infected active crayfish, and WSSV-infected diseased crayfish using high throughput sequencing technology. The results showed that WSSV infection led to significant changes in certain phyla in the intestines of crayfish, with implications for developing microbial strategies for the prevention and therapy of WSS disease.

Summary: The study identified Aeromonas veronii as a virulent bacterial pathogen infecting Procambarus clarkii, and also detected white spot syndrome virus (WSSV) co-infection. The co-infection led to 100% mortality in the tested crayfish, higher than single infections with either A. veronii or WSSV. The findings provide insights into co-infection strategies for disease diagnosis and control in P. clarkii populations.

Summary: This study investigated the phenotypic and genetic variances and relationships for body weight and body color traits of black tiger shrimp. It found that the color of cooked shrimp can be improved indirectly by genetic selection based on the color of uncooked/live shrimp. Additionally, the intensity of coloration is positively correlated with body weight traits.

Summary: This study identified the involvement of protein phosphatase 2A (PP2A) subunits in combating white spot syndrome virus (WSSV) infection in crustaceans, potentially by regulating the expression of antimicrobial substances to inhibit WSSV infection. These findings shed new light on the mechanism of WSSV infection and antiviral response in crustaceans.

Summary: This study compared the efficiency of different cryoprotectants and thawing temperatures on germ cell cryopreservation in two marine shrimp species, finding that 10% DMSO and 10% GLY with vitrification are suitable for Fenneropenaeus merguiensis and Penaeus monodon, respectively. Thawing temperature was also found to have an impact on cell viability.

Summary: The Australian red claw crayfish is a promising species for freshwater aquaculture, but it is also invasive. Investigating its reproductive system has been a topic of interest for many years, but little is known about it. This study successfully silenced a hormone involved in male differentiation, leading to sexual redifferentiation in all individuals. Transcriptomic analysis revealed significant changes in downstream genes related to stress, cell repair, apoptosis, and cell proliferation. This study provides valuable insights into the reproductive pathways of this species and potential biotechnological applications.

Summary: In this study, a novel TRIM37 homolog called PmTRIM37 was identified, which plays important roles in regulating innate immune processes, particularly antiviral and proinflammatory cytokine responses. PmTRIM37 is highly expressed in immune-related tissues and its expression is up-regulated after white spot syndrome virus (WSSV) infection. Knockdown of PmTRIM37 promotes WSSV replication and VP28 expression, suggesting its negative role in WSSV infection. Furthermore, PmTRIM37 positively regulates the NF-κB pathway and Antimicrobial peptides (AMP) expression during WSSV infection.

Summary: This study identified rhein as a potent inhibitor of WSSV infection in red swamp crayfish. Rhein inhibited viral transcription, reduced viral load, and improved the survival rate of infected crayfish. It activated JAK/STAT and NF-kappa B pathways, decreased the expression of crustin-1 and BAF, and increased the expression of C-type lectin and proPO to arrest WSSV replication. Additionally, rhein attenuated oxidative and inflammatory stresses and enhanced innate immunity. This research provides great potential for the development of prophylaxis and therapy agents for controlling WSSV infection in crustacean aquaculture.

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.
