Surviving in Changing Waters: A Synthesis of Contemporary Research on Fish Physiology in Combination with Climate Change Parameters

Fish physiology is a key field of study in fisheries science, providing a solid foundation for understanding aquatic ecosystems and driving innovation in the aquaculture sector. As aquaculture continues to be a key source of food worldwide, study in this subject has increasingly focused on the implications of climate change, which poses considerable threats to fish and other aquatic species. This review outlines current studies on fish physiological responses to several stressors related with climate change, such as changes in temperature, salinity, disease occurrence, and oxygen levels. The combination of these abiotic and biotic variables is vital, as climate change accelerates pathogen fate and dispersion and alters nutrient dynamics, influencing fish growth and survival. This study also reviews mesocosm experiments and modelling research to illustrate the significance of these interactions in developing sustainable fisheries management and enhancing aquaculture methods. Furthermore, the study identifies current research trends and recommends areas for future research to address the ongoing problems posed by climate change to aquatic resources.
