Market sampling continues. Most samples have been aged. Several cruises were made during fiscal year 1969-70. The deep water survey for Dover sole yielded questionable results. Neither spawning concentrations nor concentrations of males were located. Calculations of year class strength for English sole showed that the 1961 year class was...
Introduction:
On July 1, 1969, the Oregon Fish Comnission began a one-year study to assess the movements and abundance of pink shrimp (P. jordani) in a specific area off Oregon. The principal objectives of the study were as follows:
1) Determine the benthic movements of pink shrimp in the area...
During the 1969-70 project year emphasis was placed on spawning and rearing clams which had not been previously spawned successfully. Salinity-temperature tolerances were determined for the laboratory-reared clam larvae. Field studies comparing growth of laboratory-reared and imported Pacific and Kumamoto oysters were continued. In addition, studies comparing various methods of...
Covers: April 1, 1969 - March 30, 1970. "Objectives of Oregon's oyster mortality study for the past year included monitoring oyster mortality in Yaquina, Tillamook, and Coos bays, obtaining hydrographic data in Yaquina Bay; and furnishing oysters to the University of Washington and the Bureau of Commercial Fisheries (BCF) in...
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...
"This report covers studies conducted on Dungeness crab larvae from July 1, 1969, through June 19, 1970. Principal objectives were to determine the following: (1) the effects of crab larval concentration on growth and survival; (2) the effects of light intensity on the swimming behavior of crab larvae; (3) the...
Before the passage of the Marine Mammal Protection Act in 1972, marine mammal populations were regulated by the states. This 1970 document gives a brief history of Oregon's management of sea lions, explores issues around the shooting of sea lions, and recommends that this practice be banned.
