Shortraker rockfish (Sebastes borealis) are distributed along the continental slope in the north Pacific from Point Conception in southern California to Japan, and are commonly found between eastern Kamchatka and British Columbia (Love et al. 2002). Shortraker rockfish are among the longest-lived animal species in the world, reaching ages > 150 years. The species is viviparous with spawning believed to occur throughout the spring and summer (Westerheim 1975, McDermott 2004). Little is known of shortraker rockfish early life history and habitat preferences, as immature fish are rarely observed. Love et al. (2002) indicates the species is found at shallower depths during early life history. Adults occur in a narrow range of depths on the continental slope centered at ~350 m (Rooper 2008), often in areas of steep slope (Rooper and Martin 2012). In bottom trawl survey data, shortraker rockfish are most common through the Aleutian Islands (AI) and the central Gulf of Alaska (GOA). Studies of habitat preferences in the GOA indicate shortraker rockfish may be more abundant in boulder patches with associated Primnoa coral (Krieger and Ito 1999, Krieger and Wing 2002). Shortraker rockfish consume large benthic or nearbottom prey, including myctophids, shrimp and squid (Yang et al. 2006).
