Do fishers follow fish displaced by climate warming?
Climate change is associated with altered oceanographic conditions that tend to shift the geographical distributions of fish. To assess the impact of climate change on fisheries, one must go beyond projections of catch potential and understand how fishers respond to moving target species. Many previ...

Climate change is associated with altered oceanographic conditions that tend to shift the geographical distributions of fish.
