Fishing portfolios and shifts buffer Alaskan communities from abrupt change

New research on Alaskan fishing communities shows the crucial importance of fishing portfolios and turnover. In 1989, when there were both major ocean and market regime shifts, most communities lost fishing revenue. But those with the greatest diversity of fished species, and those that were most able to switch from one group of species to another, had little lost revenue, or even experienced increased revenue. The new research by SAFS graduate student Timothy Cline and Profs Daniel Schindler and Ray Hilborn, appears in Nature Communications.
