The researchers — from the University of Washington, the National Oceanic and Atmospheric Administration (NOAA), the University of Alaska Fairbanks and the Alaska Department of Fish and Game — analyzed nearly 30 years of revenue and permitting records for individuals fishing in Alaskan waters and tracked how their fishing choices, in terms of permits purchased and species caught, influenced their year-to-year income volatility.”
