The sablefish has made a modest contribution to Oregon's commercial foodfish landings since the early part of this century, usually incidental to the halibut longline fishery. Trawl caught sablefish now dominate landings, but in recent years a pot fishery has developed off Astoria and Newport.
The rex sole has been an important flatfish in Oregon's trawl fishery since its beginning in the 1930's. This fish is easily recognized by its characteristic long pectoral (chest) fin on the eyed side of the body.
Oregon landings of rex sole have gradually increased over the years. Initially rex...
"For State/Federal Dungeness Crab Management Program" (title page) "Surplus yield models, mark-recapture data, and length-frequency data have been used to determine how the annual catch of Dungeness crab in Washington, Oregon, northern California, and central California will react as fishing effort varies. Yield curves were estimated for Washington and Oregon...
The salmon of the Columbia River have supported an intensive fishery for over seventy years but are now showing unmistakable signs of depletion, and various factors are contributing to the rapid progress of this condition. Five species of fish enter into the commercial fishery on the Columbia River itself. These...
The housewife knows the little shrimp used for seafood cocktails and salads as the north Pacific cocktail shrimp. Fishermen harvesting them along Oregon's coast call them pink shrimp, and scientists identify them as Pandalus jordani. By any name, this crustacean is the object of Oregon's newest seafood fishery. This fishery...
Petrale sole are taken commercially from Santa Barbara, California, to Hecate Strait, British Columbia. These large deep-bodied flounders are one of the major contributors to Oregon's trawl fishery, as well as those of Washington, British Columbia, and California. Only the Dover and the English soles appear in greater quantities. This...
The Pacific sanddab has been a minor contributor to trawl fisheries off the United States and Canada. Its market potential has never been fully utilized off Oregon, even though such potential was first recognized in 1914. In 1914 the Federal research vessel Albatross caught sanddabs with a beam trawl off...
Should fishing by crab pots instead of crab rings be allowed in certain bays in Oregon? An error caused the ban on crab pots to be deleted from the statutes. This 1950 paper considers whether the ban on crabpots should be reinstated in Siletz, Yaquina and Alsea Bays. This is...
