Summary: This study investigated the effects of different ultrasonic pretreatments on the gel properties of shrimp surimi. The results showed that proper ultrasound treatment could improve the gel properties by expanding the protein and exposing more functional groups. The study provides a new technical means to improve the gel properties of shrimp surimi.

Summary: The addition of ADA to shrimp myofibrillar protein gel resulted in increased breaking force, gel strength, water holding capacity, and a denser network structure. ADA had little significant effect on the secondary structure of the protein. The main chemical bonds in myofibrillar protein were hydrogen and ionic bonds, while in the gel were mainly hydrophobic and disulfide bonds.

Summary: In this study, a novel transcription factor MYC gene was identified from Penaeus vannamei. The expression of PvMYC was constitutive in all detected tissues and highly expressed in hepatopancreas. PvMYC was up-regulated significantly and responded to low temperature stress. Overexpression of PvMYC negatively regulated autophagy, while silencing PvMYC increased autophagic activity under low temperature stress. These findings suggest that PvMYC plays a vital role in the cold adaptation mechanism of P. vannamei by negatively regulating autophagy.

Summary: This study analyzed the structural changes of shrimp proteins during digestion, predicted the immunodominant epitopes, and validated their allergenicity. The results showed that shrimp proteins were degraded into peptides during digestion, but still carried IgE epitopes that trigger allergic reactions.

Summary: This article reviews the current status and challenges of decapod crustacean farming from an animal welfare perspective. It proposes potential welfare indicators and critically evaluates the scientific evidence of sentience in commercially important decapods. Despite extensive research in stress physiology, immunology, and disease control, there is still limited knowledge on key parameters related to welfare dimensions. The article recommends further research to develop a comprehensive welfare assessment and species-specific welfare indicators for all farmed decapod crustaceans.

Summary: This study investigated the effects of dietary Wnt/β-catenin pathway activator TWS119 on the growth, immunity, and transcriptome response of Penaeus vannamei. The results showed that TWS119 improved growth, enhanced immunity, and regulated gene expression related to ribosome function and energy metabolism in P. vannamei. Increasing dietary TWS119 can potentially enhance the performance of shrimp by modulating the Wnt/β-catenin pathway.

Summary: To solve the problem of decreased product quality due to the mixing of defective shrimp during processing, a quality detection model of Penaeus vannamei based on deep learning was proposed. By expanding the self-made dataset and replacing the YOLOv5 backbone with the lightweight network PP-LCNet, the feature extraction ability of the network was effectively strengthened. The Shrimp-YOLOv5s network showed higher overall performance compared to current mainstream classical models and lightweight models.

Summary: This study established prediction models for meat yield and net meat weight in Pacific whiteleg shrimp, with the prediction accuracy reaching 0.991 for net meat weight. However, the prediction accuracy for meat yield was only 0.450. Although heritability of meat yield is not high, genetic improvement through direct selection is feasible.

Summary: The global shrimp farming industry is facing increasing threats from emerging viruses. A novel picornavirus, Penaeus vannamei picornavirus (PvPV), was discovered in moribund White leg shrimp in China in 2015. PvPV has unique genetic and protein structures, suggesting it may be a new species in the family Dicistroviridae. Further studies on PvPV could provide insight into its evolution, pathogenicity, and aid in diagnostic technique development.

Summary: This study explores the effects of ammonia stress on the molecular structure and functions of hemocyanin in Penaeus vannamei. The results show that ammonia stress alters the molecular structure of hemocyanin, affects its protein and oxyhemocyanin levels, and induces phosphorylation modification and degradation. Under moderate ammonia stress, hemocyanin undergoes glycosylation, leading to improved antibacterial activity and binding with different bacteria.

Summary: This study analyzed the response of juvenile and adult Penaeus vannamei to IHHNV infection through transcriptome sequencing and found differential expression of immune-related genes, growth-related genes, and metabolic processes. Adult P. vannamei triggered a cellular defense response and early molting to resist IHHNV, while the imperfect immune system of juvenile P. vannamei made them more susceptible to infection.

Summary: White Feces Syndrome (WFS) is an emergent disease in penaeid shrimp, associated with enteric pathogens like Enterocytozoon hepatopenaei (EHP). Experimental reproduction in pre-infected shrimp with EHP and challenged with Vibrio parahaemolyticus shows a synergistic relation leading to WFS.

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.
