Temperature effects on Pacific oyster embryos subjected to spent sulfite liquor

Creator:: Will, Theodore
Abstract:: An exploratory study of 48-hour Pacific oyster embryo bioassays employing spent sulfite liquor (SSL) in test concentrations ranging from 10 to 45 ppm was made at two incubation temperatures, 20° and 24° C. Fourteen separate bioassays, each employing embryos originating from three to four different parentages, were conducted at the...

Distribution patterns of black-tailed deer (Odocoileus hemionus columbianus) in relation to environment

Creator:: Miller, Frank L.
Abstract:: Direct observation of a known number of black-tailed deer (Odocoileus hemionus columbianus), within the Cedar Creek study enclosure in the Tillamook Burn, Oregon, was carried on throughout 1964. Observations were made from three huts located outside of the enclosure on surrounding prominences. During this period, 1,410 hours of observational time...

Age-fecundity relationships in the striped seaperch Embiotoca lateralis from Yaquina Bay, Oregon

Creator:: Swedberg, Stephen Ernferd
Abstract:: A study was conducted at Yaquina Bay, Oregon, to determine the age-fecundity relationships in the striped seaperch Embiotoca lateralis. A questionnaire was sent to California, Oregon, and Washington to ascertain what regulations were in effect, and the value of the family Embiotocidae with regard to the sport and commercial harvest....

Biology of juvenile sockeye salmon resident in Chignik River, Alaska

Creator:: Iverson, Ronald Albert
Abstract:: The life history of juvenile sockeye salmon (Oncorhynchus nerka) resident in Chignik River, Alaska, represents a departure from the lacustrine, pelagic existence typical of juveniles of this species. For this reason, the distribution, relative abundance in different parts of the river, growth, and upstream and downstream movements of juvenile sockeye...

A review of the Gadopsidae, with a description of a new species from Tasmania

Creator:: Parrish, Richard H.
Abstract:: The taxonomic placement of Gadopsidae is discussed and an evaluation of its osteological relationships with related families is given. Similarities to the more primitive genera of the trachinoids, notothenioids, and uranoscopoids are noted and the inclusion of Gadopsidae in the Trachinoidae is recommended. A description of the geological history of...
