This is an exhibit made by the Oregon Department of Fish and Wildlife to the Oregon Fish and Wildlife Commission for the November 17, 2000 meeting. Topics covered include: proposals to add Daphnia (Daphnia spp., a small crustacean in the Klamath Lake area) and flat abalone (Haliotis walallensis) to the...
This study was performed in response to doubts about the reliability of the database in place at ODFW. It consisted of surveys to verify if Chinook salmon were using the habitats previously identified and looks for discrepancies between summer habitat inventory and fall Chinook spawners. A large portion of the...
This document covers the massive decline in catch and return on trout stocked in Diamond Lake starting in the 90s and describes issues addressing the most likely cause, an increased Tui chub population competing for resources with the trout. The report discusses the persistent issue of Tui chub in Diamond...
We evaluated the effectiveness of using hatchery coho salmon Oncorhynchus kisutch presmolts to rebuild wild populations in Oregon coastal streams. Juvenile and adult populations were monitored in 15 stocked and 15 unstacked streams from summer 1980 until summer 1985. During the summers following the planting of presmolts, the number of...
This document describes the life history and abundance of both the spring Chinook salmon and the Silver salmon in the Willamette River. It also goes into detail about various factors affecting Willamette salmon runs., including pollution, dams, and logging.
Should commercial crabbing be banned in Oregon bays in order to eliminate potential conflict with recreational bay crabbers? In answering this question, this report summarizes the state of the bay crab fishery in the mid-1980s and examines esthetic and economic aspects of the issue. Includes statistics. This is a staff...
Razor clams from Clatsop Beach (Tillamook Head to Columbia River) were sampled regularly from March through September and periodically the rest of the year. Sport and commercial diggers were interviewed to obtain data on number, age composition of clams dug and harvest area. Data from other beaches south of Tillamook...
"Primary objectives . . . were to document the wild salmonid species that utilize Salmon River as a spawning area, to determine their spatial and temporal distributions, and to measure the abundance of each species." (p.1) Adults and juveniles were studied.
Project AFS-58 Final Report (part 2).
The second of three reports on a 15-year study to determine the effects of logging on the aquatic resources of three tributaries of the lower Alsea River. The study took place from 1959-1973. Primary objectives included in-depth study of population characteristics of fish species...
Project AFS-58 Final Report (part 3). The final of three reports on a 15-year study to determine the effects of logging on the aquatic resources of three tributaries of the lower Alsea River. The study took place from 1959-1973. Primary objectives included in-depth study of population characteristics of fish species...
This report discusses the harvest of intertidal non-food invertebrates in 1973, giving number of collecting permits issued and intensity of collecting by area.
This report discusses the harvest of intertidal non-food invertebrates in 1974, gives the number of collection permits issued, and describes intensity of collection by area.

The first of three reports on a 15-year study to determine the effects of logging on the aquatic resources of three tributaries of the lower Alsea River. The study took place from 1959-1973. Primary objectives included in-depth study of population characteristics of fish species...
This report consists of tables summarizing data regarding streams receiving hatchery-reared rainbow trout since 1952. It includes data such as sources, sizes of fish, and water temperatures at the planting sites. It also averages data from creel reports from 1965-1972.
This document is an analysis to determine whether Haystack Rock in Cannon Beach, Oregon should be closed to collection of non-food invertebrates, giving background for the area and discussing salient points.
This document discusses a proposal for a two-week extension to the 1973-74 crab season. It gives the opinion of the staff of the Management and Research division of OFW, and their reasoning.
Project F-82-R Final Report The results of a study to understand the ecological requirements of brown trout and determine the effects of water development and land use on fish populations in the Deschutes River. Abundance, distribution, survival, age, growth, fecundity, food, migrations and ecological relationships to other species were all...
