Brown rockfish (Sebastes auriculatus) are bottom dwellers occurring in shallow water 20 to 100 feet deep in the rocky structure and kelp forest associated mostly with the rocky shore and to some extent with the nearshore reefs. Brown rockfish mature at 5 years and live up to 18 years of age attaining a maximum length of 22 inches but averaging between 10 and 12 inches. They are light brown mottled with one or two shades of darker brown with vague dark bars dorsally and a dark brown blotch on upper part of the gill cover. They have some pinkish coloration to their fins and on the underside of the throat or lower jaw. Brown rockfish are commonly known as Bolina. The majority of Bolina are caught by anglers fishing from the rocky shore. Brown rockfish feed on crabs, i.e. dungeness, rock crabs and hermit crabs, etc, shrimp, molluscs, octopi, chitons, polychaetes (marine worms) and small fish, i.e. shiner perch, midshipmen and anchovies, etc. Brown rockfish are one rockfish that have a poisonous gland at the base of all of its fin spines.
