Effects of climate change-induced temperature rise on crustacean aquaculture: A comprehensive review

Abstract

Global warming, as a key driver of climate change, is accelerating water temperature rise, with significant implications for aquatic ecosystems. Temperature, a critical abiotic factor, directly affects the physiology, growth, and survival of aquatic organisms. In the context of aquaculture—one of the fastest-growing food sectors—crustaceans hold high commercial value due to their production volume and global demand. However, their sensitivity to thermal fluctuations poses major challenge under climate change. This review examines the impact of elevated temperatures on growth performance, food intake, moulting, immune response, and survival of major farmed crustaceans, including shrimp, prawns, crabs, lobsters, and crayfish. Broader ecological consequences, such as disruptions in nutrient cycling and disease outbreaks, are also explored. Additionally, we evaluate mitigation strategies, including dietary modification, technological innovations, biotechnological approaches, and aquaculture insurance models. By integrating physiological, immunological, and ecological evidence, this review identifies key knowledge gaps and highlighting opportunities to improve climate resilience in crustacean aquaculture. Understanding these challenges is essential for sustaining productivity and promoting adaptive management in a warming world.
