Studies of juvenile salmonids off the Oregon and Washington coast, 1982

Creator:: Fisher, Jeffrey P., Pearcy, William G., and Chung, Alton W.
Abstract:: The School of Oceanography, Oregon State University, conducted three cruises (May 19-June 2, June 7-22, and September 4-14) in 1982 to study the distribution, abundance, migration, growth and feeding habits of juvenile salmonids during their first summer in the ocean. This is the second year we have had a series...

Feeding habits of Dover sole, Microstomus pacificus; rex sole, Glyptocephalus zachirus; slender sole, Lyopsetta exilis; and pacific sanddab, Citharichthys sordidus, in a region of diverse sediments and bathymetry off Oregon

Creator:: Pearcy, William G. and Hancock, Danil
Abstract:: The feeding habits of the Dover sole and rex sole (mainly juveniles) and of slender sole and Pacific sanddab were investigated at seven stations on the continental shelf off central Oregon. Dover sole had a catholic diet, feeding on a large variety of infaunal and epifaunal invertebrates. The composition of...

Distribution and abundance of small flatfishes and other demersal fishes in a region of diverse sediments and bathymetry off Oregon

Creator:: Pearcy, William G.
Abstract:: Demersal fishes were sampled at seven stations located inshore of Heceta Bank, on Oregon's continental shelf, over a 2-yr period with a 3-m beam trawl designed to catch small fiatfishes. Two general assemblages of fishes were recognized: a shallow water 74-102 m), sandy-bottom association where Pacific sanddab, Citharichthys sordidus,was numerically...

Growth rules in the marine copepod genus Acartia

Creator:: Miller, Charles B., Johnson, John Kenneth, and Heinle, Donald R.
Abstract:: Several species of the copepod genus Acartia are shown from existing data to complete each molt-to-molt phase of the life cycle in a constant time period. This molting pattern is termed isochronal development. Increase in mass at each stage is a nearly constant fraction of the weight at the beginning...

Distribution and duration of pelagic life of larvae of dover sole, Microstomus pacificus; rex sole, Glyptocephalus zachirus; and petrale sole, Eopsetta jordani, in waters off Oregon

Creator:: Pearcy, William G., Hosie, Michael J., and Richardson, Sally L.
Abstract:: Dover and rex sole larvae attain an exceptionally large size and have a long pelagic life. Dover sole larvae (9-65 mm standard length) were collected in mid-water trawls and plankton nets during all months of the year. Judging from growth of larvae and occurrence in bottom trawls of recently metamorphosed...

Zooplankton along the continental shelf off Newport, Oregon, 1969-1972 : distribution, abundance, seasonal cycle and year-to-year variations

Creator:: Peterson, William and Miller, Charles
Abstract:: This technical report summarizes the results of a three year study of the zooplankton living in the nearshore zone off Newport, Oregon. The sampling program was part of the Early Life History (ELH) project of the Oregon State University Sea Grant Program and was designed to study the ecology of...

The Wavemeter : a land-based system for measuring nearshore ocean waves

Creator:: Zopf, D. O., Creech, H. C., and Quinn, W. H.
Abstract:: This paper describes a method for measuring nearshore ocean wave characteristics with a land-based, long-period vertical seismometer. The wavemeter system has proven to be highly reliable and produces continuous wave observations at low cost. It is now operational at six Coast Guard stations along the Oregon and Washington coasts; data...

An epibenthic sampler used to study the ontogeny of vertical migration of pandalus dordani (Decapoda caridea)

Creator:: Rothlisberg, Peter and Pearcy, William G.
Abstract:: Pandalis jordani Rathbun, like many other species of pandalid shrimps, undergo regular diel changes in their vertical distribution (Tegelberg and Smith 1957; Alverson et al. 1960; Pearcy 1970, 1972; Robinson in press). Little is known, however, about the vertical distribution and diel migrations of larval and juvenile shrimp, or at...

Comparison of the most successful and least successful west coast albacore troll fishermen

Creator:: Keene, Donald Frederick and Pearcy, William G.
Abstract:: Catch data for albacore troll boats were collected from fishermen's logbooks and from dockside interviews during the 1968, 1969, and 1970 seasons. Fishing powers of these boats were calculated and used to determine the 10 most successful and 10 least successful fishermen (highliners and lowliners, respectively) who fished off Oregon...

Catches of albacore at different times of the day

Creator:: Pearcy, William G., Panshin, Daniel A., and Keene, Donald Frederick
Abstract:: The purpose of this study is to examine the hypothesis that diel variations occur in the catches of albacore by boats trolling surface jigs off Oregon. Although albacore fishermen talk of "morning bites" and "evening bites," no published data exist, to our knowledge, confirming these trends. Studies on the feeding...
