New publications investigate links between climate change, fishing, and the abundance and geographic distribution of fishes in the California Current.

In two recent publications, researchers from Scripps Institution of Oceanography, SWFSC’s Fisheries Research Division and colleagues describe the relationships between climatic variation, fishing activity, and changes in the distribution of and abundance of exploited and unexploited fish species based on the 50-year larval fish time series in the California Cooperative Fisheries Investigations (CalCOFI).
