Copper rockfish (Sebastes caurinus), a species that is becoming increasingly important as a sport fish, were studied in two shallow areas in Puget Sound, from 1963 to 1968, to obtain information on seasonal availability, growth, maturation, feeding habits, and ecology. Specimens examined ranged from 6.8 to 47.0 cm in fork length and from 0 to 8 years old. Availability was greatest in September and October and least in June and July. Length‐weight regression was the same for both sexes but differed by time of year (W = 0.000016231 3.040252 for September to November and W = 0.000024945 2.953381 for December to March). Both sexes were usually mature at age IV. Crustacea and fish were the principal foods. The rockfish hid in rock interstices in the winter but not in the summer.
