Climate change effects on aquaculture production
<div>Climate change is now considered a risk to global food production and a
major threat to the quality and quantity of production. Food security,
particularly access to dietary protein, is increasingly being threatened
by the predicted effects of climate change. The effects of climate
change on aquaculture have been extensively studied and reviewed both at
regional and global scales because of the sector’s significant
contribution to global food security, nutrition and livelihoods. Most
studies, however, tend to explore the negative effects of climate change
projected on aquaculture while giving far less attention to the
positive ones that are very critical for adaptation strategies and are
largely biased toward showing how climate change will affect aquaculture
production systems while leaving other components of the value chain
unclear.</div>The effects of climate change on aquaculture and implications on sustainability
Climate change effects on aquaculture production are both direct and indirect. The direct effects include influencing the physical condition and physiology of finfish and shellfish stocks in production systems, while indirect effects may occur through altering the primary and secondary productivity, and structure of the ecosystems, input supplies, or by affecting product prices, fishmeal and fish oil costs, as well as other goods and services needed by fishers and aquaculture producers. The various ways through which climate change will affect aquaculture production and implications on the sustainability of the sector are presented in detail in the original publication.
Aquaculture production does not occur in a vacuum but has important links with other food production systems. Researchers have observed that to sustainably meet the ever-increasing demand for aquatic products, there is a need to recognize the strong link existing within and across the goals of fisheries, aquaculture, and agriculture systems. Fig. 1 provides a simple illustration of how greenhouse gas (GHG) emissions will affect aquaculture production as well as the contribution of capture fisheries, aquaculture and agriculture activities to climate change.
Although aquaculture activities, such as power input, transportation and feed production are considered the main pathways of the sector’s contribution to GHGs, its contribution is relatively small despite being significant when compared to other food production sectors. For example, the contribution of aquaculture to global GHGs, particularly carbon dioxide (CO<sub>2</sub>), emissions in 2010 was estimated at 385 million tons or about 7 percent of the agricultural sector’s contribution that year.

Thank you for sharing the article.
A concrete 2026 fact: a study published in npj Ocean Sustainability assessed 327 marine aquaculture species. If the Paris Agreement is met (SSP1-1.9 scenario), more than 40% of productive marine regions would remain without significant climate exposure. However, under high-emission scenarios, nearly all production zones would be affected.
Additionally, 62% of global aquaculture production (over 55 billion dollars) had not been previously assessed for climate sensitivity. That reveals a very large knowledge gap.

New study shows that meeting with the Paris Agreement is key to secure global marine Aquaculture
