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...
Data are presented on the life history and population dynamics of rex sole (Glyptocephalus zachirus Lockington) collected from Oregon waters between September 1969 and October 1973. Length-weight relationships vary little between sexes or with time of year. Otolith annuli form primarily
from January through May and were used for age...
“Internal Report GS-73-1.” Includes hand-drawn maps of estuaries studied with seining locations shown. Species identified are listed for each estuary. Appendix A outlines a proposed study program to determine the importance of estuaries as rearing areas for juvenile fish, emphasizing juvenile English sole. 19 p.
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...
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...
"This report describes for the first time, megalopal stages of the commercially important pink shrimp, Pandalus jordani, with a comparison with previously published larval studies. This will benefit future workers rearing this species' larvae and also in identification of its megalopae from plankton samples." Describes two post-larval stages. Called "Information...
Describes rearing of Oregon pink shrimp (Pandalus jordani) larvae. Studied aeration, feeding habits, water current, and light intensity and their effects on shrimp behavior. Front cover carries "Information Report." This report was digitized by an ODFW employee.
This report summarizes information obtained from groundfish surveys conducted by the Oregon Department of Fish and Wildlife from 1971 through 1974. The program was a comprehensive marine resource survey of the continental shelf and upper continental slope off Oregon between the Columbia River and Cape Blanco. Major goals were: (1)...
