Impacts of Climate Change on the Parasite–Host Relationship in Freshwater Aquaculture

Extreme temperature events brought on by climate change are occurring more frequently and with greater intensity, which has an impact on all economic activities, including aquaculture. The chapter brings insights into the effect of climate change on the aquaculture industry as well as future research on the topic, exploring specific questions: What possible repercussions can climate change have on the parasite–host dynamic in aquaculture? How is the relationship between the host, biological agents, and environment? Climate change induces alterations in the physical–chemical parameters of the water, impacting all current ecological interactions and maybe limiting fish physiology and development throughout the whole aquaculture process. Through hosts and/or biological agents, fish health is predicted to be more impacted by climate change.
