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...
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.
