The brown rockfish (Sebastes auriculatus), whose other names include brown seaperch, chocolate bass, brown bass and brown bomber, is a

ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae
. It is found in the northeastern Pacific Ocean.

Taxonomy

The brown rockfish was first formally

San Francisco, California.[3] Some authorities place this species in the subgenus Auctospina. The specific name auriculatus means "eared" thought to be an allusion to the dark spot on rear margin of operculum.[4]

Description

The Brown Rockfish has a deep body which has a depth of 33% to 37% of its

total length of 56 cm (22 in).[2] The maximum recorded weight is 3.0 kg (6.6 lb).[5]

Distribution and habitat

The brown rockfish is native to the northeastern Pacific. Its range extends from southern Baja California to Prince William Sound in the northern Gulf of Alaska.[2] These fish are most abundant in the central and southern parts of Puget Sound and from southern Baja California to Bodega Bay in northern California.[7] The brown rockfish occurs at depths from the intertidal zone down to 287 m (942 ft) and prefer areas with rocky patches or hard substrates, inhabiting areas which vary in relief from low to high. They also frequently occur around artificial structures and objects such as piers and other man-made objects, like marine debris, such as tires.[6]

Biology

The brown rockfish has a long pelagic juvenile stage which spends two and a half to three months in the water column before they settle in shallow water to depths of 36 m (118 ft). This settlement can take place as early as May and the juveniles and subadults are common close to the bottom in bays and estuaries. In some areas, like

oviparous species in which each female lays between 55,000 and 339,000 pelagic eggs per year. They are known to live for up to 34 years.[5] They are known to hybridize with quillback and copper rockfishes in Puget Sound.[6]

Fisheries

The brown rockfish was common in fish markets near San Francisco in the 19th century, as they are caught in bays and other shallow waters. Modern commercial fisheries regard this species as of moderate importance in fisheries for fresh fish and of greater importance in fisheries for live fish. Artisanal fisheries take this species on Baja California. It is an important quarry species for recreational fishers from Puget Sound south to northern Baja.[7] The flesh is said to be palatable, with a mild flavor and the fish are generally fried or, for smaller fish, cooked whole.[9]
