Trawl survey expands, selling Unalaska, new trawler paint job

摘要

Trawl survey stretches north: Thanks to 1.2 dollar million in new research funding related to loss of sea ice, federal fishery scientists say they'll be able to expand this summer's Bering Sea bottom trawl survey all the way north to the Bering Strait. "With this expansion, all of the eastern Bering Sea shelf within U.S. waters will be surveyed," says a recent write-up from the Alaska Fisheries Science Center. The annual trawl survey is among the tools scientists use to determine the size of groundfish and crab stocks. Expanding the survey farther north could yield especially interesting results for species such as snow crab that favor cold water, said Mike Sigler, a marine biologist with the science center.
