• Description:
  Scientists from the Alaska Fisheries Science Center conducted an acoustic-trawl (AT) survey in mid-February 2020 to estimate the abundance of pre-spawning walleye pollock (Gadus chalcogrammus) in the southeastern Aleutian Basin near Bogoslof Island. Twenty-six transect lines were surveyed, and 14 trawl hauls were conducted for biological measurements during the survey. This report summarizes the observed pollock distribution and biological information and provides an abundance estimate used for stock assessment.
