==Fisheries== Sablefish are typically caught in [[Bottom trawling|bottom trawl]], [[Longline fishing|longline]] and [[Fish trap|pot]] fisheries. In the Northeast Pacific, sablefish fisheries are managed separately in three areas: [[Alaska]], the Canadian province of [[British Columbia]], and the west coast of the [[contiguous United States]] ([[Washington (state)|Washington]], [[Oregon]], and [[California]]). In all these areas catches peaked in the 1970s and 80s and have been lower since that time due to a combination of reduced populations and management restrictions.<ref name="AFSC2017">{{citation |title=Assessment of the Sablefish stock in Alaska in: Stock assessment and fishery evaluation report for the groundfish resources of the GOA and BS/AI |vauthors=Hanselman DH, Rodgveller CJ, Lunsford CR, Fenske, KH |url=https://www.afsc.noaa.gov/REFM/Docs/2017/BSAIsablefish.pdf |date=2017 |publisher=North Pacific Fishery Management Council, 605 W 4th Ave., Suite 306 Anchorage, AK 99501, USA |pages=307β412}}</ref><ref name=DFO2016>{{cite web |title=A revised operating model for sablefish (''Anoplopoma fimbria'') in British Columbia, Canada | author=DFO | date=2016 | publisher=DFO Can.
