Summary: This study explored the bioaccumulation and biochemical status of Jian carp exposed to MPs and TC alone and combined. Results showed that MPs bioaccumulation was not affected by TC, but the presence of MPs changed TC content within 48 hours. Co-exposure to TC and MPs reduced oxidative damage and alleviated overexpression of immune-related genes in muscles compared to MP exposure alone.

Summary: The experiment investigated the interaction between carbonate alkalinity levels and dietary protein levels on the growth, digestive ability, intestinal immunity, physical barrier function, and microflora of Songpu mirror carp. Results showed that higher carbonate alkalinity levels led to reduced weight gain rate and increased feed conversion ratio, while higher dietary protein levels also had negative effects. The study suggests that maintaining dietary protein levels below 310 g/kg under carbonate alkalinity stress of 15 mmol/L can effectively enhance the growth and intestinal immune response of fish.

Summary: Yellow River carp is an economically-important freshwater fish that common host of epizootic bacterium Flavobacterium columnare which causes columnaris disease. This study aimed to evaluate the genetic and histopathological effects of F. columnare infection in Yellow River carp. The results showed differentially-expressed genes between infected and control groups, indicating immune response after challenge with F. columnare. High expression of inflammatory cytokines and stress proteins in infected fish may contribute to severe infection, while upregulation of chemokines and antigen presentation function could help resist F. columnare infection.

Summary: The study found that adding Clostridium autoethanogenum protein (CAP) to practical diets for juvenile Jian carp improved growth performance and antioxidant capacity, while having no obvious effects on the liver and midgut. This research demonstrates the potential of converting industrial waste into a high protein feed ingredient for aquafeeds.

Summary: Akkermansia muciniphila (Akk), a promising probiotic, has been found to alleviate hepatic steatosis and insulin resistance in mammals. However, its probiotic effect and mechanism in aquaculture are still unclear. This study investigated how Akk is involved in the glucose metabolism of common carp and found that it reduced blood glucose and TG content, promoted glycolysis, inhibited gluconeogenesis, and decreased intestinal microbiota diversity and richness. Pasteurized Akk showed stronger effects in reducing TG and promoting glycolysis compared to live Akk and cell-free supernatant.

Summary: This study assessed the potential effect of phosphorus on growth, intestinal oxidation resistance, physical barrier function, and microflora for Songpu mirror carp reared in a high-concentration carbonate alkalinity environment. The results showed that increasing carbonate alkalinity led to impaired growth, digestion, antioxidant activity, and immune response in the carp. Adequate dietary phosphorus supplementation enhanced intestinal antioxidant enzyme activities, immune response, and beneficial microflora formation.

Summary: This study investigated the effects of Humulus scandens extract on the growth performance, antioxidant responses, and intestinal microflora of Yellow River carp. The results showed that the groups fed with 1.0 g/kg and 2.0 g/kg of Humulus scandens extract had significantly higher final body weight, specific growth rate, and intestinal body index than the control group. The antioxidant activity and intestinal health of the carp were improved with the supplementation of Humulus scandens extract.

Summary: This study found that extracts of Ginkgo biloba leaves (EGbs), especially ethyl acetate extract (EAE), exhibited strong antioxidant activity and protective effects against lipid oxidation. Addition of EAE to fish feeds can effectively inhibit lipid oxidation and improve fish growth performance by enhancing digestive enzyme activity and antioxidant capacity. Moreover, dietary EAE also decreased lipid oxidation in fish meat and inhibited the induction effect of hemoglobin in erythrocytes. These findings suggest that EGb can serve as a potential natural antioxidant for fish and fish feed.

Summary: In this study, metabolomics was used to investigate the impact of thermal stress on the metabolic profile of Qingtian paddy field carp. The results showed that thermal stress altered multiple metabolic pathways, including lipid, amino acid, and carbohydrate metabolism. The findings clarify the molecular regulatory mechanism of PF carp adaptation to thermal stress and provide novel hypotheses for the biological regulation of other fish species under thermal stress.
