Climate change is causing profound modifications in marine communities and in the structure and function of marine ecosystems. Climate changes (global warming, acidification, deoxygenation, decreased salinity, increased precipitation, etc.) are causing negative impacts on marine species, effects that have been widely recorded. These changes are added to extreme events (e.g., harmful algal blooms, hypoxia, and marine heat waves) that not only affect marine species, but also the economic activities that depend on them, a clear example is aquaculture. However, in Peru there are few studies that evaluate the climate vulnerability and resilience of aquaculture production chains (APC). Therefore, in this study, a climate vulnerability assessment was carried out for 13 current and potential production chains of the Central American Pacific Ecosystem (EPCA) and the Humboldt Current Ecosystem (ECH); and an evaluation of the climate resilience of 2 productive chains. The hypothesis of this study is that intensive CPAs are less vulnerable to climate change than extensive CPAs; and that the shrimp production chain is more resilient to climate change than the fan shell production chain. The fan shell CPAs in Sechura and Paracas, and the macha shell, were the most vulnerable. The least vulnerable CPAs were cheetah, yuyo and oyster. There were no significant differences in vulnerability between intensive and extensive CPA; No significant differences were found in the resilience indices between fan shell and shrimp CPA. These results will allow prioritizing the lines of research, financing, and CPAs that require adaptation measures to climate change.
