Potential impacts of climate change on marine wild capture fisheries: an update
SUMMARY This paper provides a brief update on the potential impacts of climate change on marine ecosystems and marine wild capture fisheries based on the scientific literature published since 2007. Current models predict shifts in fish distributions of 45–60 km per decade, with 0·80 of species movin...
