"The Willamette River has the largest runs of spring chinook salmon of any tributary of the Columbia River rising in Oregon. The run to the Willamette is most unique in that the migrating fish pass up the river through Portland, a city of several hundred thousand people, and support a...
"In January 1946 the Oregon State Game Commission authorized a study of Diamond Lake to determine reason for an apparent decline in the size and number of rainbow trout with the object of maintaining a maximum annual yield through proper management." (From Introduction)
This document contains transcripts of Joel Hedgpeth’s series of lectures delivered over KPFA radio in Berkeley, California. These passionate lectures described the uses of oceanography, attempted to differentiate between oceanography and marine science, and encouraged students to pursue oceanography. Joel Hedgpeth was a director of the Hatfield Marine Science Center.
"Kokanee were originally stocked in Detroit Reservoir in 11959. This species was introduced in hopes that it would utilize pelagic zoo plankton and provide a more varied sport fishery. The trout fishery in the reservoir depends primarily on heavy plants of legal-sized rainbow trout, supplemented by stocking fingerling rainbow. As...
"The natural production of anadromous fish in many coastal streams has been seriously reduced by pollution, dams, timber harvesting, siltation, and other such forces. Many miles of streams that could be in production are not available to anadromous fish because access is blocked by log jams or natural barriers such...
"Kokanee salmon, Oncorhynchus nerka (Walbaum), are well distributed over much of central and eastern Oregon but are relative newcomers to lakes along the Oregon coast. Kokanee were first introduced into coastal waters in 1952 when 51,802 fry were planted in Woahink Lake, a few miles south of Florence. So far...

With the construction of the Marine Science Center and the opening of its Pacific Fisheries Laboratory in 1965, Oregon State University had facilities for research that would ultimately lead to breakthroughs in Pacific Coast oyster culture. "Purposes of the workshop were to review present and planned programs of research with...
The management policy of the Fish Commission of Oregon concerning the Pacific pink shrimp, (Pandalus jordani) has resulted in regulations which apply to all shrimp along the Oregon coast and do not recognize separate populations. There are several shrimp grounds along the 300-mile length of the continental shelf off Oregon...
This report has three primary objectives; it attempts to examine the relationship of various cultural systems to the marine environment, seeks to create an inventory of uses man has put the marine environment to, and makes an analysis of the attitudes of people towards the marine environment.
This paper is record of early work in oyster culture in the west coast oyster industry. It summarizes operations for a year of running the OSU pilot oyster hatchery, and subsequent recommendations for its continued large-scale production of oysters.
Juvenile English sole, Parophrys vetulus utilize Yaquina Bay, Oregon, as a nursery during at least a portion of their first year of life, but the possibility of the existence of additional nursery grounds offshore has not previously been examined. During 1971, young-of the-year first appeared in Yaquina Bay in February,...
As a prelude to tagging studies on pink shrimp (Pandalus jordani) or other laboratory studies, basic information was needed to establish criteria necessary to hold shrimp in aquariums with minimum mortality. A one-year study was conducted at the Fish Commission Laboratory in Newport to obtain data on these requirements. The...
This report is a brief overview of the status of Oregon’s oyster aquaculture in the mid to late 1970s, including discussions of trends in harvests and research into oyster breeding.
Pandalis jordani Rathbun, like many other species of pandalid shrimps, undergo regular diel changes in their vertical distribution (Tegelberg and Smith 1957; Alverson et al. 1960; Pearcy 1970, 1972; Robinson in press). Little is known, however, about the vertical distribution and diel migrations of larval and juvenile shrimp, or at...
A student report for a Civil Engineering 572 class, this document is an extensive description of the Salmon River estuary, including water flow, quality, predictions for the estuary’s future, and numerous charts and graphs.
For oysters, "The objective of these studies was to determine the biological feasibility of using the heated effluent from coastal nuclear power plants for culturing the Pacific oyster, Crassostrea gigas." (p.1) Work included oyster growth experiments, seasonal growth experiments and closed system studies. For salmon, "The objective of these studies...
An article detailing the intense storms on the Pacific Northwest coast in the last 10 days of October 1977. Reprinted from Mariners Weather Log 22 (2).
This is a student report which studies the effects of wave action on intertidal zonation at Yaquina Head. It includes hand-drawn diagrams of quadrants sampled at the location.
"Seafood canneries in lower Yaquina Ray, Oregon process shrimp (Pandalus jordani), Dungeness crab (Cancer magister), a variety of bottom fish and several salmon species. The shrimp wastes are screened and discharged directly into the Ray beneath the cannery docks. During the shrimp processing season about 3.8 million liters of wastes...
This three page report details a shark attack on a surfer that tooks place on November 27, 1979 off Cannon Beach, Oregon. The bite marks on the surfboard are detailed including x-rays showing the teeth marks.
Beginning in the late 1960s and throughout the past decade, unusual, perhaps neoplastic, large cells with rather consistent characteristics were described in mussels, clams, and oysters from several bays in the United States and the United Kingdom. The large, characteristic cells are thought by many workers to be abnormal leukocytes...
Experiments were performed to determine the rate of recolonization of sediment-associated microalga and effects of infauna on microalgal biomass and production. Estuarine sediment was defaunated and transplanted to the field and the laboratory. Recolonization of sediment by flora and fauna, relative to control sediment, was measured by chlorophyll a, gross...
Patterns of seasonal abundance of harbor seals at Netarts and Tillamook Bays, Oregon, were documented by recording numbers of seals hauling out on tidally exposed sand flats in both bays. Harbor seal abundance at Tillamook Bay peaked during pupping (May-June) and molting (August) periods, while peak abundance at Netarts Bay...
Sediment-associated microalgal biomass expressed as chlorophyll a concentration, total organic matter concentration expressed as ash-free dry weight, and hourly rates of net community primary production and community oxygen consumption were measured at monthly intervales at medium sand, fine sand, and silt sites between 0.5 and 2.0 m above MLLW during...
Juvenile red hake Urophycis chuss were collected while they were inhabiting sea scallops Placopecten magellanicus , and the effects of appetite and food availability on prey consumption and growth were examined under laboratory conditions. Fish took increasing amounts of live amphipods Gammarus annulatus with increasing periods of food deprivation up...
The food habits of the 2 dominant larval pleuronectids off the Oregon coast - English sole Parophrys vetulus and butter sole Isopsetta isolepis - were analysed. Most specimens were collected during January-April 1971 and March-April 1973. As is typical of larval fishes, I. isolepis larvae ingested a variety of prey...
Behavioral responses of juvenile bluefish P. saltatrix L. exposed to cold water in a vertical thermal gradient were measured under controlled laboratory conditions. The temperature regime was similar to conditions that these fish encounter in their inshore and estuarine habitats along the Middle Atlantic coast. Measures included activity, schooling, position...
"The fish management plan for the North Umpqua River system (below Soda Springs Dam) is designed to promote effective management of the fish resources in that river. It is prepared to inform interested citizens and agencies of management objectives and promote their input in choosing the appropriate courses of action....
A simple behavioral test was devised to determine the effects of multiple acute stresses on the avoidance response time of fish. Groups of freshwater-adapted juvenile chinook salmon Oncorhynchus tshawytscha were exposed to a sudden overhead light and the time it took each fish to reach cover was noted. Tests were...
