Summary: This study investigates the toxic effects of MC-LR on crayfish. The results show that MC-LR can effectively accumulate in the hepatopancreas, gills, and intestines of crayfish. Antioxidant-related genes show different expressions in response to MC-LR-induced oxidative stress. MC-LR also leads to histological changes and disruptions in the intestinal flora of crayfish. These findings provide new insights into the toxic impacts of microcystins on aquatic crustaceans.

Summary: This study aimed to explore the defense mechanism of Procambarus clarkii to abamectin. The results showed that abamectin caused oxidative damage to P. clarkii, resulting in damage to the defense system, suppression of nonspecific immunity and antioxidation, and promotion of apoptosis. This study provided a theoretical basis for the healthy cultivation of P. clarkii and further research on the defense mechanism of aquatic animals to pesticides.

Summary: In this study, Limosilactobacillus fermentum GR-3 strain isolated from water was found to have high adsorption capacity for Arsenic (As) and strong antioxidant abilities. When added to crayfish feed, the strain effectively reduced the concentration of As(III) and restored gut microbiota dysbiosis caused by As(III) exposure. The application of this strain in aquaculture also resulted in a decrease in As(III) accumulation and increased production.

Summary: This study investigated the toxic effects and mechanisms of ammonia on red swamp crayfish at two different developmental stages. The findings revealed that ammonia exposure caused severe hepatopancreatic injury and impaired antioxidant capacity. Additionally, it was observed that crayfish at a later developmental stage exhibited stronger antioxidant and detoxification capacities, enabling quicker recovery after ammonia exposure.

Summary: The quality of lake wetlands has decreased due to elevated concentrations of certain trace elements. Consuming crayfish from these trace element concentrated lake wetlands can be hazardous for waterbirds and human health. This study quantified the bioaccumulation of Cd, Ni, Pb, and Zn in sediments and abdominal muscles of Procambarus clarkii in Caohai lake wetland, China. The results showed significantly elevated levels of Cd, Ni, Pb, and Zn in sediment, and some samples of crayfish had Cd, Pb, and Zn levels exceeding the maximum permissible limits. These findings suggest that lake sediment could be an important source of feed for P. clarkii and that normal consumption of crayfish posed low to no health risk for waterbirds and local inhabitants.

Summary: In this study, TiO2-supported Pd catalysts were used to selectively hydrogenate the C--C bonds in the Adda moiety of MC-LR, achieving rapid detoxification in water. Catalytic hydrogenation significantly decreased the toxicity of MC-LR by 90.8% within 30 minutes, demonstrating effective detoxification. Surface adsorption and cationic Pd played crucial roles in the reaction kinetics.

Summary: This study demonstrated the anti-fibrotic effect of microcystin-RR on bleomycin-induced pulmonary fibrosis rodent models, attenuating pulmonary inflammation, collagen deposition, and fibrotic markers expression. Microcystin-RR treatment also reduced the number of pulmonary M2 macrophages and inhibited epithelial-mesenchymal transition and fibroblast-myofibroblast transition triggered by M2 macrophages. These findings suggest that microcystin-RR is a promising candidate for therapeutic and prophylactic strategies against idiopathic pulmonary fibrosis.

Summary: This study investigated the effects of different feeds on the metabolic parameters of largemouth bass. Feeding with iced fish increased the content of saturated fatty acids, monounsaturated fatty acids, and some polyunsaturated fatty acids in muscle tissue, while feeding with commercial feed increased the content of polyunsaturated fatty acids and higher fatty acids. Feeding with iced fish led to significant decreases and increases in the abundance of Firmicutes and Tenericutes in the gut microbiota. Feeding with commercial feed enriched pathways related to carbohydrate metabolism and the digestive system, while feeding with iced fish enriched pathways related to disease resistance.
