Marine ecosystems have already been impacted by climate change. It is generally accepted that these impacts affect marine productivity, fish distribution, habitat and diversity. However, it is hardly known how fisheries respond to these changes. In order to understand how fisheries are responding to ocean warming, researchers from the Future Oceans Lab at CIM–University of Vigo, the Basque Centre for Climate Change (BC3), CSIRO and Marine Support investigated the distribution of purse seiner activity in the Atlantic Ocean. The new publication shows the spatiotemporal trends of tropical tuna fisheries in the central-eastern Atlantic Ocean and finds that fleet activity shifted southward from the equator over the studied period (1991-2017). A mix of climate change, institutional, management and technological factors explain the observed shifts, but management and institutional settings are the most powerful factors to offset climate change distribution impacts on these fisheries. The findings support management as a crucial tool to reach sustainable fisheries, which undergo serious threats apart from over-exploitation or pollution, which is the case of the ongoing climate change.
