Description

Abstract: The Oregon Department of Fish and Wildlife conducted tagging experiments in 1977 and 1978 to determine the inshore - offshore exchange of lingcod Ophiodon elongatus off the central coast-of Oregon. We-tagged 293 lingcod near Johnson Rock in inshore waters off Newport in December 1977 through March 1978 and 3,818 near Stonewall Bank in offshore waters off Newport in July 1978. Female lingcod composed 16% of the fish tagged near shore and 89% of the fish tagged offshore. We recovered 20 (6.8%) and 637 (16.7%) tagged fish from inshore and offshore tagging, respectively. Most tagged fish were recovered from the area when: they were tagged. Only 11% of recovered fish had moved 5 nautical miles or more from the area of tagging. Less than 5% had moved more than 25 nautical miles. Interchange between Johnson Rock and Stonewall Bank was not observed. Changes in depth, as measured by depth increments originating at each tagging site, were uncommon; 87% of the males and 77% of the females were recovered within 10 fathoms of the depth at their tagging site. The offshore commercial fishery did not appear to strongly affect nearshore stocks of lingcod, but some lingcod whose range probably included nearshore reefs, were caught by commercial fishermen trawling tor sole in nearshore waters.
