Project AFS 31 Final report The final report of a study to determine whether discrete races of summer steelhead races exist in the Rogue River, and if so to isolate each race in terms of life history and ecological behavior, including such points as time of entry, seasonal positioning and...
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...
"Prepared for the State/Federal Dungeness Crab Management Program. May 1974." "One of the initial objectives of the State/Federal Dungeness Crab Management Program is to evaluate crab mortality caused by certain fishery practices. The areas of most concern include mortality caused by trawling, handling of softshell and sublegal crabs, lost pots...

"As requested, crab fishermen, processing plants, boat moorages, and chambers of commerce along the Oregon coast ware interviewed to obtain their thinking on crab seasons and regulations." Interviews were conducted from Astoria to Brookings.
This report gives information on the Coos River shad fishery, going into detail about recent (for 1957) trends in shad fishing such as licenses issued, total fish caught per location, and length frequency.
In 1949, the Army Corps of Engineers dredged Coos Bay. “Despite objection of local residents, commercial clam diggers, and the Fish Commission” the Corps dumped dredging spoils on a commercially important clam bed, and destroyed much of it. “This year, with an earlier start and more data, it is hoped...
"The Siletz River ... is the only short coastal stream in Oregon inhabited by a run of what are generally thought to be native summer steelhead. Hatchery-reared progeny from Siletz River stock have been released into and have become established in two other Oregon coastal streams, the Nestucca and Wilson...
