Photo from August 2008 fisheries survey in the Beaufort Sea (north of Alaska). Bottom trawl catches were dominated by invertebrates; 41% of the total weight captured in the bottom trawls was Ophiura sarsi, a brittlestar (pictured here).

Fisheries experts at the University of British Columbia have prepared time series estimates of total harvests in U.S. Arctic fisheries: Baseline Study of Marine Fisheries Catches from Arctic Alaska: 1950–2006. Prior to this, estimates of regional harvests, particularly for small scale subsistence fisheries, were intermittent and fragmentary.
