Description

Abstract: Rockfish (family Scorpanidae) are an important segment of Oregon trawl landings. Two distinct fisheries commonly produce nineteen species with 5 others rarely seen. A description of catch and catch per unit effort in the Pacific ocean perch and "other rockfish" fisheries is provided. Also reported are species composition of sampled catches from a program started in 1963. Trends evident in the fishery are discussed. Eight species were major contributors in 1963-71 Oregon landings: Sebastes flavidus, S. pinniger, S. entomelas, S. melanops, S. paucispinis, all in the other rockfish group. Three major contributors to the Pacific ocean perch fishery were S. alutus, S. crameri, and S. reedi. The fishery for Pacific ocean perch was developed by successful gear technology and reached a peak of 13.6 million pounds in 1965, about one-half the total Oregon trawl catch. At that time, Soviet trawlers appeared in search of Pacific hake but also engaged in the perch fishery. By the end of 1971, landings of perch had dropped from an estimated 12.2 million pounds to 288,000 pounds for S. alutus alone. S. crameri landings in 1971 exceedcd those of S. alutus, and the former species may replace the latter in importance.
