An average of approximately 200,000 pounds of bay clams were harvested annually in Oregon for the years 1943-49, inclusive. The commercial harvest of bay clams is composed of the gaper, cockle, and softshell clams. The recreational, or noncommercial, harvest of bay clams is composed mainly of the gaper, cockle, softshell,...
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...
Tuberculosis in salmonoid fishes was first observed in the 1952 run of fall chinook salmon (Oncorhynchus tshawytscha) returning to the Bonneville Hatchery of the Oregon Fish Commission. In the studies reported here, tuberculosis was found not only in adult spring chinook but in silver salmon (0. kisutch), blueback salmon (0....
An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes. A vitamin E-deficient diet of low rancidity produced a severe microcytic anemia with strong immature red cell response and granulocytosis occurring 2 to 4 weeks before a drop in hemoglobin and hematocrit...
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...
Clatsop Beaches, characterized by flat beach-face slope (1:70) and small sandsize (0.2 mm.), have supported commercial and recreational fisheries for the razor clam (Siliqua patula) for many years. Tracing the linear growth of two year classes through more than one year following set led to a validation of the ring...
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...

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...
During a tagging operation conducted in 1951 on the Alsea River, 1,142 adult silver salmon were tagged with plastic Petersen-type tags and stainless steel jaw tags. An attempt was made to determine whether tagged fish released in different apparent conditions suffered differential mortalities. Under the hypothesis that the recovery of...
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...

This report covers studies conducted from July 1,1967, through June 30, 1968 to determine the effects of various laboratory diets and diet...
It is possible that the large fluctuations In annual Dungeness crab landings are caused by displacement of crab larvae by currents. We studied the effects of various environmental factors on crab larvae survival and behavior. Tests were conducted on cultured zoeae and megalopae and on wild megalopae.
Our studies showed...

"Oyster mortality data collected from suspended trays at three subtidal locations in Yaquina Bay disclosed an unusually high 26.5% Pacific oyster (Crassostrea gigas) mortality during the study year. Almost all of this mortality resulted from culling damage which occurred previous to introduction of the oysters into trays. Native oyster mortality...

Finally, it gives the total harvest and age composition data, and contains the results of a survey of clam diggers on Clatsop County beaches for 1965.
In 1967, Oregon State University applied to the Bureau of State Lands for a 10-year lease on 153 acres of tideland in Netarts Bay, in order to conduct research on shellfish. A change in state law in 1970 invalidated the old terms of the lease. The University decided to request...

"We monitored oyster mortality in Yaquina, Coos, and Tillamook bays from July 1966-March 1972. Pacific oyster (Crassostrea gigas) mortality in Yaquina Bay appears to be lower than in any other reporting area on the Pacific Coast, generally less than 2% per year. Native oyster (Ostrea lurida) mortality ranged from 9.6-28.2%....
"Striped bass (Morone saxatilis) were tagged on the Umpqua and Smith rivers (Figure 1) to estimate the numbers of bass recruited to the commercial fishery and to gather information on migration habits of bass in these rivers. Small numbers of striped bass were tagged in the summers of 1971 and...

1. The Indians at Celilo Falls catch an average of over 2,600,000 pounds of fish each year, in dip nets in a manner very much the same as used by their ancestors. 2. The bulk of the fish caught at Celilo Falls is from the upriver fall run of chinook...
1. Six major types of commercial gear have been used to take salmon and steelhead on the Columbia River; namely, gill nets, set nets, seines, traps, fish wheels and dip nets. 2. The five important commercial species in the Columbia River are chinook, silver, blueback and chum salmon and steelhead...
In spite of the progressive restrictions of the commercial river fishery during the past fifty years, the trend of the salmon populations of the coastal rivers has been downward. It is almost impossible to isolate and analyze separately the causes of this decline, and any attempt to saddle one factor...
Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower...
In July and August 1961, nine lots of 500 juvenile silver salmon each were subjected to one-, two-, three- and four-week periods of complete starvation. The three- and four-week periods produced the best growth checks for that time of year, but were generally of inferior quality to those produced in...
Personnel of the OFC and OGC sampled various station of Coos Bay, Oregon to define areas used by several species of fish in the bay. Students at the University of Oregon Institute of Marine Biology sampled main channels with an otter trawl and observed animals on the tide flat. Primary...
The fall chinook index of abundance was 128% of the long-term average, and presumably would have been even higher had survey conditions in the central and north coast not been so difficult.
The surveys of spawning fish in coastal rivers in 1971 indicate that stocks of chum salmon remain at a low, although apparently stabilized level. Fluctuations are probably the result of year-class survival and age at maturity, rather than continued decline of the species.
The fall chinook index of abundance was...

"Letters and newspaper articles concerning the low quantity and poor quality of Dungeness crabs in Nehalem Bay have been frequently received by the Oregon Fish Commission. Popular opinion usually places the blame for the lack of legal-sized bay crabs in the Nehalem estuary upon the adjacent commercial crab fisheries, A...
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.
In 1973 Oregon entered into a cooperative State/Federal Dungeness Crab Management Program with the states of Washington and California, the National Marine Fisheries Service, and the Pacific Marine Fisheries Commission. A study team consisting of two economists and a biologist was hired to review the Dungeness crab fishery and management...
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.
