Strategies to Mitigate Climate Change-Imposed Challenges in Fish Nutrition

Abstract

Climate change is not only a future threat to food security but also a present reality that has its signature in all aspects of sustainability. The changes in climate and global warming have potential short-term and long-term effects on aquaculture production. Changes in the ecosystem, especially variations in temperature, can alter the physiology of fish and create stress in animals. Mitigation of stress in fish and crustacea can be done through nutritional interventions. Functional feed additives or nutraceuticals play a major role in the mitigation of stress in fish. The improved tolerance and feed conversion efficiency can also support the fish to cope with climate- related challenges. Additionally, providing a precise, eco-friendly feed that stimulates gut health, growth, and immunity in fish can be a better strategy to support the growth and well-being of fish in the changing climatic conditions.
