Blue Rockfish . The maximum size and geographic and depth ranges of this species are unclear due to previous confusion with Sebastes diaconus and S. ciliatus . Thus the values presented here should be regarded as tentative. To at least 38.5 cm ( 15.2 in ) TL ( Schmidt 2014 ), but perhaps to 53.3 cm ( 21 in ) TL ( Phillips 1957 ). At least central Oregon ( 44.5°N ) to northern Baja California ( 32.5°N ) ( Frable et al. 2015 ), and probably to just south of Punta Baja ( 29°54’42”N , 115°49’W ), northern Baja California ( Klingbeil and Knaggs 1976 ). Records from Alaska (i.e., Chatham Strait and Kruzof Island, south-eastern Alaska and perhaps Elfin Cove, south-eastern Alaska ( Love et al. 2005 )) are likely S. diaconus . It is likely that all “Blue Rockfish” from the Bering Sea and the western Gulf of Alaska refer to S. ciliatus (referred to as Dusky Rockfish in Mecklenburg et al. 2002). Depth: surface to at least 156 m ( 512 ft ) (M.L., unpubl. data), and probably including the intertidal ( Moring 1972 ); a record of about 549 m ( 1,800 ft ) ( Eschmeyer and Herald 1983 ) seems anomalously deep and is without documentation.
