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...
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.
This is a 1966 proposal to transplant about 500 red abalone (Haliotis rufescens) into Whale Cove on the Oregon Coast, and see if the abalone prospered. This proposal was approved, and the Oregon Dept. of Fish and Wildlife did launch this experiment.
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...
"Laboratory studies during the 1971-72 project year consisted primarily of developing mass culture and planting techniques for Manila littleneck clams (Venerupis semidecussata).

The interpretation of the neoclassical model of dynamic labor supply is straight forward. A rational agent exposed to a temporary increase (reduction) in wages will respond by increasing (reducing) working hours. However, empirically such behavior has been hard to confirm. Most income increases are not temporary; hence a substantial income...
Covers July 1, 1970 to June 30, 1971. Reports on studies of spawning and larval rearing of Manila littleneck clams, native littleneck clams, butter clams and gaper clams, including field work. "Field studies comparing growth and survival of laboratory-reared and imported Pacific and Kumamoto oysters were completed. We continued studies...

By 1948, Oregon’s clamming regulations spilled over into fifty-one different sections of administrative rules. They were “cumbersome” at best. The previous legislative session had repealed many outdated laws but kept them in effect until the Fish Commission could study the issue and propose new regulations. The Commission had been studying...
