Gulf of Alaska Bottom Trawl Survey Research Brief 2023

April 29, 2023

This is a flyer that describes the biennial bottom trawl survey in the Gulf of Alaska.

Our objective is to characterize the distribution and abundance of the ecologically and economically important species that live on or near the seafloor in Alaska. Our survey produces observations of species occurrence, species densities, and biological characteristics such as length, gender, age, and food habits. These data collected on our surveys are used to support annual stock assessments and ecological models.
