Summary: This study investigated the effects of histamine on the neuroendocrine-immune network of Litopenaeus vannamei. The results showed that histamine injection significantly affected the neuroendocrine factors, intracellular signaling pathways, immune parameters, and antioxidant parameters in shrimp. Histamine may regulate the immune and antioxidant defense mechanisms of shrimp through different pathways.

Summary: Endoplasmic reticulum (ER)-stress is an important cause of aquatic animal diseases. This study investigated the influence of ER-stress in Litopenaeus vannamei using RNA-Seq, and identified differentially expressed genes (DEGs) related to ER-stress, immune, and metabolism. The study also suggested that ER-stress might play an important role in the immune response of shrimp.

Summary: Exposure of Litopenaeus vannamei to imidacloprid leads to oxidative stress and decreased immunity, disrupted gut microbiota function, and overall transcriptome changes. Imidacloprid also inhibits autophagy pathways and affects detoxification gene expression in shrimp, resulting in internal toxicity.

Summary: The ammonia tolerance capacity of different breeding families of Litopenaeus vannamei was compared. The results showed significant differences in ammonia adaptability among different families. Ammonia-tolerant L. vannamei may possess enhanced ability to excrete ammonia, better capacity to convert ammonia into less toxic products, and sufficient energy reserves for ammonia-compensating processes.

Summary: This study investigated the effects of different concentrations of zinc on the growth performance, morphological changes, physiological changes, and gene expression in white shrimp hepatopancreas. The results showed that high concentrations of zinc significantly reduced survival rate and growth performance, and caused structural damage and zinc accumulation in the hepatopancreas. Zinc exposure led to decreased activities of digestive enzymes and total antioxidant capacity, and increased production of reactive oxygen species and malondialdehyde. Transcriptome analysis revealed many differentially expressed genes, and qRT-PCR validation confirmed the accuracy of the results. The study demonstrated that zinc exposure caused severe histopathological changes and altered immune, antioxidant, and detoxifying responses by regulating gene expressions.

Summary: The effects of different stocking densities on Litopenaeus vannamei were investigated in terms of growth performance, immune response, and transcriptome. The results showed that increasing stocking density significantly decreased the survival rate, final body weight, weight gain rate, specific growth ratio, and protein efficiency ratio of L. vannamei. It also led to changes in the activities of immune enzymes and gene expression in the hemocytes.

Summary: This study investigates the differences in gene expression between tolerant and susceptible families of Pacific white shrimp Litopenaeus vannamei under normal and high-salinity conditions. Results suggest that crustacyanins and serine proteases play important roles in shrimp tolerance to high salinity. The findings provide valuable information for understanding the mechanism of high-salinity tolerance and could contribute to the breeding of shrimp varieties with improved tolerance.

Summary: This study investigated the effects of dietary archaeal carotenoids supplementation on the growth and antioxidant capability of Litopenaeus vannamei juveniles. The study found that dietary archaeal carotenoids significantly enhanced astaxanthin content in shrimp muscles and carapaces, as well as the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Transcriptome analysis revealed the molecular processes and pathways affected by archaeal carotenoids, including reactive oxygen species generation and antioxidant enzymes. The findings provide valuable insights into how archaeal carotenoids enhance the antioxidative system in L. vannamei.

Summary: This study compared the transcriptome of Litopenaeus vannamei Zoea larvae and adults infected by Vibrio parahaemolyticus using high-throughput Illumina sequencing. The results showed that pathways involved in the innate immune response were more enriched in the Zoea stage compared to the adult stage, suggesting the existence of innate immunity against Vibrio vulnificus during the Zoea larvae stage. These findings provide useful information for the study of innate immunity in shrimp larvae.

Summary: This study evaluated the stress resistance of Litopenaeus vannamei through family breeding and compared the tolerance of different families to high ammonia-N, high pH, and low salt stress. The population with a female parent from the United States showed stronger tolerance to stress compared to the population with a female parent from Thailand. The TM hybrid population exhibited heterosis in high ammonia-N and high pH tolerance, while family MM7 had strong low salt tolerance.

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.
