Summary: The study found that using a transport bag containing oxygen and seawater can effectively extend the post-capture survival time of small swimming crabs, possibly due to metabolic adaptation including a switch in energy generation pathway and decline in certain metabolic processes. Energy homeostasis is crucial for crab survival during transport.

Summary: This study investigates the boldness and agonistic behavior of crabs and finds that boldness affects the fighting behavior between female and male crabs. Male crabs have a higher willingness and ability to fight, and bolder crabs engage in more fights compared to shy individuals. Energy reserves and metabolic rates may be factors influencing agonistic behavior in crabs.

Summary: Portunus trituberculatus, an important marine economic species, has a rapidly developing aquaculture industry. However, wild capture and germplasm degradation have become a serious issue, calling for the development of artificial farming and germplasm resource protection. Sperm cryopreservation technology is an effective method, and this study compared three methods for obtaining free sperm, finding that mesh-rubbing is the best. Optimal cryopreservation conditions were determined, including sterile calcium-free artificial seawater as the medium, 20% glycerol as the cryoprotectant, and specific cooling and thawing procedures. However, the expression of sperm-related genes and enzymatic activities significantly decreased after cryopreservation, indicating damage to the sperm. Overall, this research improves the cryopreservation technology for P. trituberculatus sperm and provides a technical basis for establishing a cryopreservation library of crustaceans.

Summary: The spectrum of light has significant effects on the development, respiratory metabolism, and antioxidant capacity of the larvae of Portunus trituberculatus. Cyan light is found to be the optimum spectrum for the larvae's survival and development, while red and yellow lights negatively impact their growth. The oxygen consumption rate decreases and the ammonia excretion rate increases as the larvae develop. Exposure to red light leads to a decrease in the oxygen-nitrogen ratio, indicating increased protein utilization in respiratory processes. In terms of the antioxidant system, green, cyan, and yellow lights are found to have the lowest malondialdehyde levels, and cyan light exhibits the highest total antioxidant capacity.

Summary: The study systematically investigated the mating behavior of Portunus trituberculatus under indoor conditions and the role of shelters in the mating process. Results showed that crabs with shelters preferred hiding in them, leading to shorter total mating durations compared to those without shelters. Despite the presence of shelters, mating rates between groups remained similar, highlighting the importance of shelters in reducing cannibalism and improving survival rates during mating.

Summary: This study investigated the activation function of a type I heat shock protein 40 (PtHSP40-I) from Portunus trituberculatus in the TLR pathway. The results showed that PtHSP40-I can bind to lipopolysaccharide and peptidoglycan, and also exhibit binding activity towards the extracellular leucine-rich repeat domain of Toll-like receptors. Moreover, PtHSP40-I promotes the translocation of the transcription factor Dorsal and participates in regulating the expression of anti-lipopolysaccharide factor and crustin. These findings provide insights into the activation mechanisms of the TLR pathway mediated by HSP40 and have implications for disease control in P. trituberculatus aquaculture.

Summary: This study evaluated the effects of different dietary cholesterol levels on the growth, cholesterol metabolism, and gene expression in female swimming crabs. The results showed that crabs fed a diet with 1.00% cholesterol exhibited the best growth performance, and tissue cholesterol concentrations were positively correlated with dietary cholesterol level. Functional fatty acid contents and hormone levels related to molting were also influenced by dietary cholesterol. The study concluded that an optimal dietary level of cholesterol benefitted the accumulation of functional fatty acids, regulated lipid metabolism, and improved molting and growth in swimming crabs.

Summary: Concern for animal welfare in aquaculture is increasing, and environmental enrichment (EE) is an effective means to improve animal welfare by influencing their behavior. This study found that the presence of suitable substrate in EE effectively reduced territoriality in swimming crabs, with sand having the most significant effect. The study concluded that the presence of substrate, especially sand, is an effective means of improving the welfare of cultured swimming crabs.

Combining stable isotopes and elemental contents improved the discrimination accuracy, with high correctness rates for claw meat, abdominal meat, and gills. This method supports the geographical traceability and origin identification of P. trituberculatus.

Summary: Microsporidiosis in aquaculture has caused severe economic losses. Understanding the molecular mechanism of host responses to aquatic microsporidia infection is important for controlling microsporidiosis. This study analyzed the transcriptome of muscle tissues from two crab species at different stages of Ameson portunus infection, revealing differential molecular responses and dynamic host responses. The findings suggested that A. portunus can regulate host cellular responses to achieve proliferation, and the infection causes DNA damage in host cells. Metabolic function and immune responses were significantly affected in severely infected crabs, leading to reduced food intake and slow growth. The two crab species exhibited different immune responses to A. portunus infection.

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.
