The Acadian redfish ("Sebastes fasciatus") is a marine deep-water fish belonging to the family Sebastidae.ITIS | ID = 166774 | taxon = Sebastes fasciatus | year = 2008 | date = 16 August] FishBase species | genus = Sebastes | species = fasciatus| year = 2008 | month = August]

Found in the northern Atlantic Ocean, the Acadian redfish lives in depths of 70 – 592 meters. "S. fasciatus" is colored reddish-orange, can live up to 50 years or more and reaches lengths up to 20 inches. [http://www.state.me.us/dmr/recreational/anglerguide/doyouknowyourcatch/documents/acadianredfish.pdf Acadian redfish] , Maine Dept. of Marine Resources.] They feed on a variety of crustaceans, mollusks, and smaller fish. In addition, the Acadian redfish mates in the fall to late winter through means of "ovoviviparous reproduction" with around "15,000 [to] 20,000 extruded larvae produced per female" per season.Ralph K. Mayo, Jon K. T. Brodziak, John M. Burnett, Michele L. Traver, and Laurel A. Col, " [http://www.nefsc.noaa.gov/sos/spsyn/pg/redfish/ The 2005 Assessment of Acadian Redfish, "Sebastes fasciatus" Storer, in the Gulf of Maine/Georges Bank Region] ," Northeast Fisheries Science Center Reference Document 07-06, National Oceanic and Atmospheric Administration, U.S. Department of Commerce (April, 2007).] Due to its slow growth rate, low fecundity, harmless nature, tendency to "hit almost any bait," and being considered a great food fish, the redfish has become endangered.FishBase species | genus = Sebastes | species = fasciatus| year = 2008 | month = August] ]

The Acadian redfish is extremely similar in appearance to the deepwater redfish "Sebastes mentella". The two species can be distinguished by the number of soft rays in the anal fin, internal examination of the gas bladder, or by genetic testing.Ralph K. Mayo, Jon K. T. Brodziak, John M.
