In the late 1950s, "two California men" came to Oregon to learn if there were abalone here, and found them in the southern part of the state. The resulting publicity and interest inspired this document, an attempt to develop regulations for a new fishery. It is an internal discussion paper...
Each year, after crabs molt, there is a time when their shells are soft, and are not filled up with crab meat. This soft-shelled state is undesirable for fishers. Since the timing of molting varies from year to year, it is difficult for fishery managers to set the start date...
This document outlines a proposal to plant red abalone in Whale Cove in Lincoln County, Oregon, in an attempt to establish a population in the northern half of the state. A proposed regulation includes a ban on all shellfish harvesting in Whale Cove.
The objective of this project was, "To establish, in Oregon, a coastwide red abalone sport fishery and a limited commercial fishery as stocks dictate." Starting in 1967, abalone were planted at Whale Cove in Lincoln County, and were later planted at the Rogue River Reef in the Gold Beach area...
Hybrids with abnormal development were obtained when particular
genotypes of Phaseolus vulgaris L. were crossed. The phenotypic
aberrations of the F₁s included retarded growth, chlorosis of the
trifoliate leaves and the formation of adventitious roots on the
hypocotyls. The expression of the abnormalities was dependent on the
temperature. At high...
An area in Coos Bay was dredged to make room for a log boom. This terse 1953 report concerns a bulkhead constructed to hold the dredging spoil and the proposed new log boom.
"During the summer of 1961, a seafood dealer at Charleston, Oregon hired SCUBA ... divers to harvest clams in subtidal areas with hydraulic equipment. This operation proved to be quite efficient and was attended by considerable publicity. During the summer of 1962, several commercial and personal-use diggers equipped themselves with...
In 1968 the Oregon Fish Commission (now Oregon Department of Fish and Wildlife) initiated P.L. 88-309 funded studies to develop techniques to spawn and rear several species of bay clams. After our successful spawning and rearing studies, we planted the laboratory-produced juvenile clams on various tideflats of several estuaries to...
1. Despite their importance in determining the rate of both energy gain and expenditure, how the fine-scale kinematics of foraging are modified in response to changes in prey abundance and distribution remain poorly understood in many animal ecosystems. 2. In the marine environment, bulk-filter feeders rely on dense aggregations of...
