The rockfish has a total of 8 weak head spines. It is originally all-black, but turns a mottled gray on the sides with age, often nearing white. It grows up to 25 in (64 cm) in length, and is found to a depth of 200 fathoms (366 m), though usually at the range of >83 fathoms (152 m). Rockfish is prime fishing game, and a reproductive rate unusually high for its slow-growing genus makes it more resistant to fishing than its cousins, such as the Yelloweye rockfish, are. They are harvested in Oregon, California, Washington, British Columbia, Alaska, and the Pacific. They are a fairly common catch along the West Coast of North America, where populations are stable. Schools of adults often aggregate over rocky bottoms or at the sea surface, habits that make them susceptible to targeted fishing. Learn more about Black Rockfish
