"With the implementation of the recreational shellfish license in 2004, ODFW decided to re-initiate a study of the recreational component of the Dungeness crab fishery. The pilot study was performed to assess the effort and catch of recreational Dungeness crabbers on the Columbia River estuary during the fall and winter...
This is an account of an experiment in tagging and releasing Dungeness crabs into Yaquina Bay in early 1957. Did they travel to the ocean, to another bay, or did they stay in Yaquina Bay?
A study was undertaken in the fall of 1948 by the Oregon Fish Commission to determine the possible presence and importance of a delay in the migration of adult chinook salmon (Oncorhynchus tshawytscha) at Bonneville Dam on the Columbia River. Approximately 650 chinook were captured, tagged, and released at the...
An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes.

Mimeographed copy of a report, presumably to the Oregon State Game Commission. Includes maps and original b+w photographs of Rogue River dams, fishways, and fishing in the late 1920s. The author was extremely frank about the issues of the day, particularly law enforcement issues.
The object of this report is to discuss the following shellfish regulation problems: 1) offshore crab seasons; 2) minimum size and gear for commercially-caught bay crabs; 3) and the gaper clam season in Coos Bay. These regulations have received some criticism recently and are scheduled to be discussed at the...

Ages were determined for 65 fish from the 1947 run and for 287 fish from the 1949 run. In 1947 the percentage composition by age was as follows: 32.3 percent 3-year-old fish, 66.2 percent 4-year-old fish, and 1.5 percent 5-year-old fish. An approximate 95 percent confidence interval for the true...
Samples, consisting of scales, length and weight measurements, and sex determinations of chum, pink, and silver salmons, were taken from the commercial catch in the Columbia River in 1914. Five hundred eighteen chum scales were examined. All fish had gone to sea early in their first year; and 70.5 percent...
"As the human population has grown, the recreational and commercial use in our estuaries has increased as well. Many people have more leisure time while others facing economic pressures have turned to natural resources to supplement their food needs and/or income. The increased demand has resulted in conflicts of philosophy...

In response to those concerns, in May of 1999 the Oregon Department of Fish and Wildlife's Ocean Sampling Project began counting the number...
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...

California and Steller sea lions (Zalophus californianus, Eumetopias jubatus, respectively) are considered sentinel species because they have long life spans, are long-term coastal residents, feed at high trophic levels, and have large blubber stores that serve as depots for anthropogenic toxicants. There are few studies on sea lion health and...
