Tillamook Bay chum salmon are caught commercially by gill-nets, both set and drift, and from 1928 through 1949 the landings have averaged 819,689 pounds per season. More chum salmon are caught on Tillamook Bay than on the rest of the Oregon coastal rivers combined. These fish enter the ocean only...
In November, 1952, severe winter storms breached the protective Bayocean Peninsula at the mouth of Tillamook Bay. Before the month was out, the gap had widened to almost a mile. Subsequent sedimentation, erosion and salinity changes damaged oyster beds in the Bay. This document recounts interviews with oyster growers about...
Part I. To aid in the management of the Tillamook Bay commercial salmon fishery, a tagging program was conducted on the salmon and steelhead trout runs in 1953. General migration behavior, the minimum length of time the fish remained in the fishery, population sizes, and fishing mortalities were determined from...
Results of studies beginning in 1947 on the biology of the Dungeness crab (Cancer magister) in Oregon coastal waters are reported. A review is made of the history of the fishery with regard to trend of the catch by magnitude, area, and season; the development and conduct of the fishery...
A survey was made on this date for the purpose of ascertaining whether or not log jams in the Elk City region of the Yaquina River and Elk River (Yaquina River tributary) were a serious menace to the passage of salmon.
