Simple Summary: For many aquatic animals, temperature is an important environmental factor that influences how they develop, reproduce, behave, and survive. For both economic and ecological reasons, the Qingtian paddy field carp (Cyprinus carpio var qingtianensis) is an important species of fish in China. It is an important aquaculture fish suitable for rice–fish coculture systems. In the current study, we utilized metabolomics to investigate the impact of differential metabolites and metabolic pathways in Qingtian paddy field carp liver tissue under thermal stress. Our findings clarify the molecular regulatory mechanism of PF carp adaptation to thermal stress at the metabolic level and offer novel hypotheses for the biological regulation of many other fish species that generate thermal stress. Extreme fluctuations in water temperature lead to significant economic losses for the aquaculture industry. Cyprinus carpio var qingtianensis (locally called Qingtian paddy field carp), is a local variety commonly found in Zhejiang province, China. Unlike traditional aquaculture environments, the water temperature range between day and night in the rice field environment is much larger, and the high temperature in summer may exceed the growth threshold of fish because there is no manual intervention; therefore, the study of how the Qingtian paddy field carp (PF carp) adapts to high-temperature conditions can shed light how the species adapt to the rice field environment. To investigate the molecular mechanisms of this fish under thermal stress, the liver metabolomics of Qiangtian paddy field carp (PF carp) were analyzed. In this study, metabolomics was used to examine the metabolic reaction of PF carp (102 days old, 104.69 ± 3.08 g in weight, 14.65 ± 0.46 cm in length) at water temperatures of 28 °C (control group, CG), 34 °C (experimental group (EG) 34), and 38 °C (EG38). The results show that 175 expression profile metabolites (DEMs), including 115 upregulated and 60 downregulated metabolites, were found in the CG vs. EG34. A total of 354 DEMs were inspected in CG vs. EG38, with 85 metabolites downregulated and 269 metabolites upregulated. According to the pathway enrichment study, various pathways were altered by thermal stress, including those of lipid, amino-acid, and carbohydrate metabolism. Our study presents a potential metabolic profile for PF carp under thermal stress. It also demonstrates how the host responds to thermal stress on a metabolic and molecular level.
