review · Aquaculture and Fisheries
This review examines how rising anthropogenic temperatures affect aquaculture, detailing impacts on species' general physiology, growth performance, survival, reproduction, immunity, and gut and skin microbiome. It also explores effects on aquatic ecosystems, including pathogen-associated disease outbreaks, aquatic parasites, vaccine efficacy, and the toxicity and uptake of heavy metals and pesticides. The paper considers responses across various freshwater, euryhaline, and marine species. Crucially, it discusses mitigation strategies for climate change adaptation, such as nutrition, genetics, selective breeding, biotechnology, nanotechnology, bacteriophage therapy, and improved management practices, aiming to ensure sustainable aquaculture productivity despite global warming.
Understanding how rising temperatures affect aquaculture is crucial for maintaining global food security. As a vital source of protein, aquaculture's vulnerability to climate change threatens its productivity and the livelihoods it supports. This research helps identify challenges and potential solutions for sustainable food production in a warming world.
This review identifies critical areas for applied research and development in aquaculture. Findings could inform the creation of new feeds, genetic programmes, and biotechnological tools for developing more temperature-resilient aquaculture species. It also highlights the need for improved management and husbandry practices. These insights are valuable for industry partners and policymakers seeking to develop and implement climate adaptation strategies for sustainable aquaculture production. This is early-stage research informing future applied solutions.

The reliance of aquaculture production on the ambient environment suggests its vulnerability to climate change. Global warming has led to the increase in water temperatures hence exerting a direct and indirect effect on several aquaculture species. Temperature is one of the major abiotic driving factors of the growth and survival of aquatic organisms. Extreme temperatures above their thermal threshold tend to lower their performance, health, and productivity. This paper, therefore, aims to give a detailed and comprehensive review on the influence of anthropogenic temperature increase on the general animal physiology, growth performance, survival, reproduction, digestive enzyme activity, immunity, differential expression of microRNAs and apoptosis-associated genes as well as gut and skin microbiome of aquaculture species. Likewise, the impacts of increasing water temperature on aquatic ecosystems with regards to pathogen-associated disease outbreaks, aquatic parasites, vaccine efficacy as well as toxicity, and uptake of heavy metals and pesticides are presented. To provide examples of how increasing water temperatures will impact the global trends of aquaculture production, a couple of freshwater, euryhaline, and marine species, as well as cold-water and warm water species, have been chosen to give a broader perspective on how different aquaculture species respond to temperature fluctuations above their thermal threshold. In the same regard, mitigation strategies for climate change adaptation in the context of global warming such as nutrition, genetics, selective breeding, aquaculture biotechnology, aquaculture nanotechnology, and bacteriophage therapy as well as management and husbandry practices are discussed to ensure a sustainable and continued aquaculture productivity.
