Key identification features
- Deep, compressed body in solid black to dark gray, with a stocky, typical rockfish profile
- Bold, continuous bright yellow stripe running from behind the head, along the base of the dorsal fin, and down toward the tail
- Yellow mottling sometimes present on the sides below the main stripe
- Large eyes and a moderately spiny dorsal fin typical of rockfish
- Relatively small for a rockfish, usually 20-30 cm (8-12 in), rarely exceeding 45 cm (18 in)
- Fins mostly dark, matching the body, with only faint yellow tinting near the base
Common look-alikes
- Yellowtail rockfish: overall body is brown to olive rather than black, and lacks the sharply defined yellow stripe
- Black rockfish: solid black or dark gray without any yellow stripe or mottling
- Tiger rockfish: has multiple reddish vertical bars rather than a single yellow lateral stripe
Where you'll see one
China rockfish are found close to rocky reefs, boulder fields, and crevices in cold nearshore waters of the northeastern Pacific, from Alaska to central California, usually at shallow to moderate depths.
