#SABLE FISH LICENSE#
Sablefish longline fishers are regulated under a "K" tab license and can fish either hooks or traps. The longline fisheries are deepwater, targeting depths between 5 m. The domestic fishery is conducted using longline Korean traps with modest amounts landed using longline-hooks and trawl nets. Foreign fishing was conducted from 1961 to 1981 and gradually phased out after the declaration of the 200-mile fishery conservation zone in 1977. Sablefish have a long history of exploitation with recorded landings starting in 1913. The long lived nature of this species is likely a strategy to ensure survival over extended periods of low recruitment resulting from environmentally unfavourable conditions. The production of strong year-classes is believed linked to higher copepod abundance arising from favourable environmental conditions. Sablefish recruitment is variable with strong year -classes that occur periodically. Age, growth and maturity parameters vary considerably among areas and depths. Maximum sizes are ~80cm and the oldest fish aged to date is 113 years. Growth is very rapid with female average size at maturity of 55 cm attained at 3-5 years. Juveniles are highly migratory with significant movement from nursery areas in Hecate Strait to the Gulf of Alaska and the Bering Sea. Juveniles migrate inshore over the following six months and rear in nearshore and shelf habitats until age 2-5 when they migrate offshore and into the fishery. Larval sablefish are found in surface waters over the shelf and slope in April and May. This species spawns in Jan-March along the continental shelf at depths greater than 1000 m. waters, with a split at approximately 51.25 ° N latitude based on differing patterns of recruitment and growth. In Canada, DFO conducts separate analyses for northern and southern B.C. National Marine Fisheries Service for the Bering Sea, Gulf of Alaska, and Wash-Calif. Independent assessments are conducted by the U.S. Although, there is sufficient movement among areas to consider sablefish throughout their range as one population genetically, the movement of adults is limited enough to enable assessment and management on a smaller scale. Abundance is centered in northern BC and the Gulf of Alaska. Sablefish ( Anoplopoma fimbria), often referred to as Blackcod, inhabit shelf and slope water to depths of > 1500 m, from central Baja California to Japan and the Bering sea. They are long-lived, with some reaching over 80 years of age. Sablefish can grow to be quite large, to more than a metre in length and can weigh between 11 and 25 kilograms. On their dorsal side, sablefish are dark grey or greyish-green, often with paler blotches, and have two widely separated dorsal fins. They have a large mouth filled with very small teeth and a tail with a slight indent.
Sablefish have a slim, elongated body covered with small scales. Adult sablefish are found near bottom over soft substrate, living at depths of up to 2,700 metres juveniles migrate inshore for several years, where they can be found in shallow waters, and then migrate offshore as adults. Sablefish are found near the continental shelf and slope of the Pacific Ocean, their eastern range beginning near Baja, California and extending north to British Columbia and Alaska, then westward over the Bering Strait to Kamchatka and Japan.
