Brown rockfish get their scientific name auriculatus, which means eared in Latin, from the dark blotch found on their gill cover. This “cheek patch” helps distinguish this species from other similar species. They come in various shades of light brown with extensive darker brown mottling. Brown rockfish have prominent spines on their head and heavy bodies. They can grow to 22 inches long and weigh up to 5.9 pounds. Like all rockfish species, this species has internal fertilization and fully formed larvae are released live from their mother’s bodies. The larvae live in the water column before settling to the bottom in mixed sand and rocks after 2.5 to 3 months. Genetic studies suggest low dispersal distances of less than 6 miles per generation. Brown rockfish mature at 4 to 10 years and can live at least 34 years. The population in Oregon waters seems to be centered off Cape Perpetua. They eat primarily fish, crabs, and shrimp, but will also consume worms, clams, fish eggs, and sea stars.
