The yelloweye is one of the world's longest-lived fish species, and is cited to live to a maximum of 114 to 120 years of age. As they grow older, they change in color, from reddish in youth, to bright orange in adulthood, to pale yellow in old age. Yelloweye live in rocky areas and feed on small fish and other rockfish.
It attains lengths greater than one metre (>39 inches) and weighs up to 20 kg (44 pounds). In the Gulf of Alaska, shortraker rockfish are sampled annually during longline surveys and are most abundant between depths of 300–400 metres (980–1,310 ft). [7] It is a bathydemersal species found over soft substrates. [4]

[11] According to the Oregon Department of Fisheries and Wildlife, the sport harvest of nearshore rockfish (such as quillback, copper and china rockfish) off the Oregon coast has been 6-12 metric tons annually between 2004 and 2009.
The orange roughy's metabolic phases are thought to be related to seasonal variations in the fish's prey concentrations, with the inactive phase being a means to conserve energy during lean periods. Slimeheads are pelagic spawners ; that is, spawning aggregations are formed and the fish release eggs and sperm en masse directly into the water.
