Abstract:: This report summarizes program progress in FY 1973. Activities were directed entirely at completing the second phase of the work started in 1971, i.e., to complete the resource survey of the continental shelf off Oregon between the Columbia River and Cape Blanco. Objectives of the survey were to obtain estimates...

Abstract:: This report summarizes program progress in FY 1974. Activities were directed entirely at completing the third of four phases of work started in 1971. The survey conducted in September 1973 was the second run over the continental shelf off the northern Oregon coast. Objectives of the survey were to obtain...

Abstract:: This report summarizes project progress in FY 1974. Activities were directed entirely at completing the fourth and final phase of work started in 1971, i.e., to survey groundfish resources on the continental shelf off Oregon between the Columbia River and Cape Blanco. Objectives of the survey were to obtain estimates...

Abstract:: This report summarizes program progress in FY 1972. Activities were directed almost entirely toward the groundfish survey of the continental shelf off Oregon between the Columbia River and Cape Blanco. Since the area was too large to be surveyed in one cruise, it will be surveyed over a two year...

Abstract:: Groundfish surveys off Oregon were conducted over a four year period (1971-74) between the Columbia River and Cape Blanco. Primary purpose of the surveys was to obtain estimates of biomass of important groundfish occupying the continental shelf and upper continental slope. Survey design was based on a 5 x 5...

Abstract:: Groundfish surveys off the Washington coast were conducted in September of 1975 and 1976 between Cape Flattery and the Columbia River. The primary purposes of the surveys were to obtain estimates of biomass and further our knowledge on population parameters of important groundfish species, especially flatfish, occupying the continental shelf...

Creator:: Johnson, Steven L., Barss, William H., and Demory, Robert L.
Abstract:: From January 1980 to January 1981 approximate monthly sampling of a unique rockfish (Scorpaenidae) fishing area on Heceta Bank, Oregon was undertaken using acoustic techniques and trawling aboard chartered commercial fishing vessels. Rankings of density of fish sign observed on acoustic transects were regressed against selected environmental variables. Acoustic abundance...
