Description:

This report compares the distribution and relative abundance of 37 fish species and six invertebrate taxa with side-by-side maps from the 2017 and 2019 EBS and NBS shelf bottom trawl surveys. For select and common fish species, abundance-at-length plots comparing the 2017 and 2019 EBS and NBS surveys are also presented. Survey results reported herein include estimates of bottom trawl survey biomass for most fishes and invertebrates, and estimates of population size, geographic distributions, and abundance-at-length of select fish species.
