H. Gilbert, 1896 | synonyms = }} The longspine thornyhead (Sebastolobus altivelis) is a species of fish in the Sebastidae family. It is found in deep waters of the northeastern Pacific Ocean.[1] Longspine thornyhead are similar in appearance to shortspine thornyhead though they don't grow as large and are typically found in deeper water.[2] Both shortspine and longspine thornyhead have been harvested in commercial fisheries with the period of peak catches occurring in the 1980s and 1990s.[2] DistributionThe shortspine thornyhead is native to the cold waters of the northeastern Pacific Ocean and is found from the Aleutian Islands, Alaska to southern Baja California, Mexico.[1] Its depth range is between {{convert|201|and|1757|m|0|abbr=on}}[1] but it primarily occurs deeper than {{convert|600|m}}.[2] StatusSeparate stock assessments for longspine thornyhead in the waters off Alaska and the West Coast of the United States have estimated the stock as healthy (above the management limits) with overfishing not occurring.[2][3] In the Canadian waters off the coast of British Columbia, a COSEWIC report declared the species a "special concern" based on the slow life history and declining trend in abundance, though no estimates of abundance or stock status were made.[4] References1. ^1 2 {{cite web |url=http://www.fishbase.org/summary/Sebastolobus-altivelis.html |title=Sebastolobus altivelis Gilbert, 1896 Longspine thornyhead |publisher=FishBase |accessdate=2018-01-04}} {{Taxonbar|from=Q1235581}}2. ^1 2 3 {{Citation| author = Stephens A, Taylor IG| title = Stock Assessment and Status of Longspine Thornyhead (Sebastolobus altivelis) off California, Oregon and Washington in 2013| publisher = Pacific Fishery Management Council| place = Portland, OR| year = 2013| url = https://www.pcouncil.org/wp-content/uploads/Longspine_Assessment_2013.pdf}} 3. ^{{Citation| vauthors = Echave KB, Hulson PJ, Shotwell SK| title = Assessment of the Thornyhead stock complex in the Gulf of Alaska, in Stock Assessment and Fishery Evaluation Report for the Groundfish Resources of the Gulf of Alaska| publisher = North Pacific Fishery Management Council| place = 605 W 4th Ave, Suite 306, Anchorage AK| year = 2015| url = http://www.afsc.noaa.gov/REFM/Docs/2015/GOAthorny.pdf}} 4. ^{{Citation| author = Committee on the Status of Endangered Wildlife in Canada| title = COSEWIC assessment and status report on the longspine thornyhead Sebastolobus altivelis in Canada| publisher = COSEWIC| year = 2007| place = Ottawa| url = https://www.sararegistry.gc.ca/virtual_sara/files/cosewic/sr%5Fsebastolobus%5Faltivelis%5Fe%2Epdf}} 2 : Sebastolobus|Fish described in 1896 |
