Response of Rice Flower Carp ( Cyprinus Carpio VAR.) to High-Temperature Stress: Mechanisms and Limits of Tolerance

Published: Jan. 1, 2025

Climate change presents a considerable challenge to the sustainable development of aquaculture. Research on impact high-temperature stress rice flower carp ( Cyprinus carpio var.) is still limited. In this study, (Cyprinus were exposed four temperature treatments (26°C as CK, 28°C TL, 30°C TM, and 32°C TH) for 14 days. The findings revealed that high temperatures significantly influenced diversity gut microbiota. Moreover, disrupted structural integrity intestinal liver tissues, causing notable damage. It also impaired antioxidant system, leading accumulation malondialdehyde (MDA) inducing oxidative stress. At transcriptional level, differentially expressed genes (DEGs) associated with protein processing pathway (e.g., HSP40, HSP70, Bip) PPAR signaling PPARδ, CPT1) upregulated during adaptation. However, further increases inhibited their expression, highlighting crucial roles in adaptation carp. conclusion, displayed degree tolerance up 30°C. Beyond threshold, health physiological functions adversely affected. Our study provides valuable reference understanding aquatic animals.

Mulberry leaf extract reduces damage by regulating the oxidative response, immune response and intestinal flora of largemouth bass (Micropterus salmoides) under chronic heat stress

Frontiers in Marine Science, Journal Year: 2025, Volume and Issue: 12

Published: Feb. 7, 2025

Chronic heat stress (HS) induces oxidative damage, low immunity, and intestinal flora disturbance of fish, posing great challenges to the aquaculture industry. As an important plant extract, mulberry leaf extract (MLE) has been shown have antioxidant immune-boosting properties. This study evaluated protective effect dietary MLE on HS-induced liver injury in Largemouth bass ( Micropterus salmoides ) based damage parameters, immune composition. Fish were randomly assigned into three groups: CON group (ambient temperature, 26°C, basal diet), HS (33°C, + diet supplemented with 9 g/kg MLE). significantly decreased final body weight, specific growth rate, villus length, muscular layer thickness, ACE Chao1 indices, lipase, trypsin, total superoxide dismutase (T-SOD), glutathione peroxidase (GPx), alkaline phosphatase (AKP), lysozyme (LZM) activities, but increased feed conversion aspartate aminotransferase (AST) activity, reactive oxygen species (ROS), malondialdehyde (MDA), complement 3 (C3) contents, relative abundances Proteobacteria Plesiomonas . Compared group, improved GPx, ACP, LZM indices intestine, numbers vacuoles inflammatory cells, AST GLU, MDA, ROS contents. Dietary also up-regulated mRNA expressions gpx , tg f-β il-10 jnk2 bcl-2 down-regulated il-8 tnf-α caspase-3 atf4 chop ire1, traf2 jnk1 TRPV MCU VDAC liver. In conclusion, supplementation could improve growth, diversity heat-stressed largemouth bass, alleviate hepatic injuries by regulating inflammation, stress, apoptosis, providing a theoretical basis for development as treatment against HS.

Dietary Pelargonium Sidoides extract mitigates thermal stress in Oreochromis niloticus: physiological and immunological insights

Veterinary Research Communications, Journal Year: 2025, Volume and Issue: 49(3)

Published: March 24, 2025

Abstract Extreme water temperatures caused by climate change constitute a serious threat to aquaculture producers. Aquatic ectotherms, which are unable regulate their body temperature, highly affected temperature changes and serve as excellent models for studying the effects of these factors. This study aimed examine impact extreme variation on growth, biological indices, antioxidant capacity, histology, disease resistance Oreochromis niloticus . The fish were exposed 17 °C, 25 °C (control), or 33 30 days, imitating events. Additionally, mitigation trial was conducted via dietary Pelargonium sidoides root extract (PS). Compared with that at growth performance significantly impaired thermal stress. exposure O. stress, especially cold elicited significant increases in stress biomarkers (cortisol glucose), hepatorenal functions (AST, ALT, LDH, creatinine), lipid profiles (triglyceride, cholesterol, HDL, LDL). Cold induced immunosuppression terms reduced total protein, phagocytosis, serum bacterial activity, immunoglobulin, white blood cells, all increased susceptibility Aeromonas hydrophila infection mortality. In addition severe pathological lesions gills, liver, intestine, causes an imbalance antioxidant/oxidative Nevertheless, PS counteracted detrimental impacts conclusion, may be recommended enhancing immunity antioxidative mitigate These findings useful developing hypotheses about physiology immunology extreme-temperature environments.
