Summary: Research on the Pacific white shrimp LvWnt11 gene show that it plays different roles in immune responses against Vibrio parahaemolyticus and white spot syndrome virus infections. LvWnt11 regulates expression of various immune-related factors and may help to uncover immune mechanisms in crustaceans.

Summary: In this study, a MIP-T3 homolog from shrimp Litopenaeus vannamei was cloned and identified. The LvMIP-T3 played a positive role in the TRAF6/NF-kappa B/AMPs axis-mediated defense response and facilitated the expression of antimicrobial peptides to oppose infection.

Summary: After evaluating the effects of functional feeds on gene expression and WSSV resistance in Litopenaeus vannamei shrimp, it was found that shrimp fed with turmeric and maca meal, as well as algae extract, showed higher survival rates against WSSV infection compared to those fed with reference feed, vitamin C, and beta-glucan. The transcriptomic response of shrimp fed with turmeric and maca meal and algae extract feeds indicated differentially expressed genes potentially related to WSSV resistance.

Summary: This study evaluated the combined use of the brown seaweeds Sargassum filipendula and Undaria pinnatifida dry biomass as feed additive for Pacific white shrimp reared in biofloc system. The results showed that the addition of seaweeds did not significantly affect shrimp growth and survival, but it led to changes in the gut microbiota and improved resistance to pathogens and thermal stress.

Summary: The drug Coumarin 3004 was found to significantly inhibit WSSV replication and reduce mortality in infected shrimp, showing potential for aquaculture application. It may promote AMPs-related gene expressions to inhibit WSSV replication, but does not entirely block transmission. Consecutive use of Coumarin 3004 further decreased mortality in infected shrimp, offering novel possibilities for treating WSSV infection in shrimp farming.

Summary: The National Aquatic Animal Disease Surveillance Program (NAADSP) in China has been conducting nationwide surveillance for major crustacean pathogens, including white spot syndrome virus (WSSV), since 2007. A proficiency test (PT) was conducted in 2021 to evaluate the molecular detection of WSSV in 170 laboratories across the country. The results showed satisfactory performance in qualitative analysis using conventional nested-PCR, while quantitative analysis using real-time PCR had a slightly lower satisfaction rate.

Summary: In this study, the recombinant protein VP28 (VP26 or VP24) was used for immune protection experiment. Crayfish immunized with VP28 showed a higher survival rate compared to those immunized with VP26 or VP24 after WSSV challenge. VP28 immunization inhibited WSSV replication in crayfish, increasing the survival rate to 66.67% after infection. VP28 treatment enhanced the expression of immune genes, total hemocyte counts, and enzyme activities in crayfish. It also reduced hemocyte apoptosis, both before and after WSSV infection.

Summary: This study elucidated the transmission dynamics of white spot syndrome virus (WSSV) in shrimp. It was found that the progression of white spot disease (WSD) was rapid and irreversible, with viral DNA shedding detected within 6 hours of disease onset. Host-to-host WSSV transmission primarily occurred around the time of death. Furthermore, exposure to water contaminated with WSSV-infected shrimp resulted in a significantly higher infection risk compared to exposure to feces or molts.

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.
