In aquatic systems, more evidence has accumulated since AR5 on warming-induced shifts  of species  , causing significant challenges for resource allocation between different countries and fishing fleets. Quantitative assessments of climate change impacts on production are still limited, but Free et al.  estimated a 4.1% global loss of the maximum sustainable yield of several marine fish populations from 1930 to 2010 due to climate change. The effects of climate change on aquaculture are apparent but diverse, depending on the types and species of aquaculture  . Temperature increases, acidification, salt intrusion, oxygen deficiency, floods and droughts have negatively
