Summary: The aim of this study is to assess the toxic effects of polyethylene microplastics (PE-MPs) on crucian carp by examining bioaccumulation, hematological parameters, and antioxidant responses. Results showed that the accumulation of PE-MPs in different tissues of crucian carp increased with the concentration, with the highest accumulation in the intestine, followed by the gills and liver. Hematological parameters, plasma components, and antioxidant responses were significantly affected by PE-MPs in a concentration-dependent manner. Exposure to >= 32 mg/L of PE-MPs resulted in a significant decrease in red blood cells, hemoglobin content, and hematocrit values. Additionally, exposure to >= 32 mg/L of PE-MPs induced oxidative stress in the liver, gills, and intestine, leading to elevated levels of superoxide dismutase, catalase, and glutathione S-transferase, and decreased glutathione levels. The interaction between PE-MPs and exposure periods did not produce significant changes.

Summary: This study investigated the acute toxicity and bioaccumulation of chlorantraniliprole (CAP) on crucian carp. The results showed that CAP had low toxicity but significant accumulation in fish muscles. Sub-chronic exposure to CAP led to oxidative stress, detoxification inhibition, and disrupted gut microbiota composition in fish. These findings highlight the potential adverse effects of CAP on fish and the need for caution when using it in aquaculture systems.

Summary: This study investigated the effects of waterborne lead (Pb) exposure on the intestinal structure and function of crucian carp. The results showed that Pb exposure led to intestinal dysbiosis, morphological disruption, oxidative stress, and immune injury in crucian carp. Additionally, Pb exposure increased the abundance of pathogenic bacteria, further exacerbating intestinal damage. These findings suggest that gut microbiota changes can serve as biomarkers for evaluating heavy metal pollution.

Summary: This study found that the addition of 0.05% APS had the best growth-promoting effects on Furong crucian carp, and improved muscle elasticity and chewiness. The 0.15% APS group had the highest spleen-somatic index, and the 0.05% group had the longest intestinal villus length. The addition of 0.05% and 0.10% APS significantly increased antioxidant capacity and decreased MDA content in the fish.

Summary: Aquatic food is an important source of micronutrients for human beings, and aquaculture plays an increasingly important role in providing this food source. However, bacterial infection poses a severe threat to aquaculture and strategies for managing these infections without antibiotics are lacking. This study investigates the metabolic changes of crucian carp infected with Aeromonas hydrophila and identifies fructose as a crucial biomarker. Supplementation of fructose increases fish survival rate by enhancing the expression of lysozyme and complement 3, leading to reduced bacterial load. These findings demonstrate a metabolism-based approach to manage bacterial infection by modulating the immune response.

Summary: With the aggravation of water eutrophication, cyanobacterial blooms have become a common environmental pollution problem, which may have potential joint toxicity on aquatic organisms, especially during the bloom period. In this study, adult male zebrafish were exposed to joint solutions of microcystin-LR (MC-LR) and nitrite to investigate the neurotoxic effects and underlying mechanisms. The results showed that the joint exposure of MC-LR and nitrite had synergistic neurotoxic effects on the structure and neurotransmitter systems of fish brain, which might be achieved through the disruption of antioxidant capacity.

Summary: This study evaluated the effects of nitrite on oxidative damage in Grass Carp blood cells. Results showed that nitrite exposure led to a decrease in hemoglobin concentration, an increase in methemoglobin concentration, increased levels of reactive oxygen species, malondialdehyde, and mitochondrial membrane potential. The antioxidant defense mechanism of the blood cells was activated, but higher doses or longer exposure periods disrupted the balance of oxidant-antioxidant homeostasis.

Summary: This study explored the performance of the recirculating pond aquaculture system (RPAS) on grass carp. The results showed that RPAS had lower concentrations of nitrogen compounds in the water and led to higher growth rates and lower feed conversion rates in the fish. The expression of growth-related genes was also increased in the fish cultured in RPAS ponds. Additionally, RPAS helped reduce oxidative stress and enhance muscle umami flavor in the fish.

Summary: To control eutrophication in aquatic ecosystems, upgrading conventional constructed wetlands to aeration wetlands is common. However, efforts to reduce dissolved inorganic nitrogen (DIN) discharge have overshadowed the importance of dissolved organic nitrogen (DON). This study found that intermittent aeration in aeration wetlands introduces large amounts of DON and bioavailable DON in effluents, while decreasing total nitrogen (TN). The increase in DON discharge can influence phytoplankton composition and stimulate harmful species, indicating the need to regulate DON discharge alongside DIN.

Summary: Long-term ecological restoration can partially restore aquatic ecosystems and alleviate the crisis of freshwater fish biodiversity. The distribution of fish communities in the Hun River Basin showed spatial differences along the longitudinal gradient and was influenced by agricultural land, urban land, and grassland. The health status of the Hun River varied, with the upper and middle reaches being in better health and the lower reaches being poorer, mainly due to different levels of human activities.

Summary: Metabolomics studies were used to investigate the influence of the high-altitude aquatic environment on indigenous fish metabolites. Different metabolite concentrations were found in the livers of fish at high and low altitudes, indicating different metabolic processes such as oxidative stress, energy metabolism, carbohydrate metabolism, and lipid metabolism. The mTOR signaling pathway, apoptosis, and lysosome were enriched between groups to ensure energy supply and limit tissue damage in fish at high altitudes. Nicotine and methoprene, two organic pollutants, showed different effects in fish at different altitudes. Overall, this study provides important insights into fish adaptation to high-altitude environments and organic contaminants pollution.

Summary: This study examined the effects of acute thermal stress on skeletal muscle growth and quality in gibel carp. Results showed that the muscle nutrient content was significantly higher at 20°C, with the muscle being more tender and elastic. The gene expression levels of the MRFs family were upregulated after 1 hour and gradually decreased. The study suggests that gibel carp can adapt to acute thermal stress to some extent, but it eventually leads to a decrease in muscle growth rate and quality.
