Against the backdrop of global climate change, the frequent occurrence of marine heatwaves significantly impacts the stability and health of swimming crab (Portunus trituberculatus) aquaculture systems; indeed, high-temperature stress has become a critical environmental factor constraining the industry's sustainable development. This paper systematically reviews the mechanisms by which high-temperature environments affect the physicochemical properties of culture water, production performance, and disease incidence, focusing on key physiological responses such as metabolic disorders, heightened oxidative stress, compromised immune function, and intestinal microbial imbalance. Based on this, and addressing the health management needs of swimming crabs under high-temperature conditions, the paper summarizes key technical systems, including water quality regulation and ecological optimization, nutritional and immunological enhancement, and intelligent monitoring with precision control. Furthermore, drawing on case studies from typical high-temperature culture seasons, the paper comprehensively evaluates the effectiveness of these health management measures in improving survival rates, mitigating disease risks, and stabilizing production performance. Research indicates that establishing an integrated health management system—grounded in environmental regulation, centered on nutritional and immunological modulation, and supported by digital monitoring—is an effective strategy for enhancing the heat tolerance and aquaculture resilience of swimming crabs. Future efforts should focus on further elucidating the mechanisms of high-temperature stress, developing precision health management technologies, and integrating intelligent aquaculture systems to drive high-quality, sustainable development of the swimming crab industry amidst climate change.
