Oyster mortality study : summary report, 1966-72

Creator:: Gibson, Gary G. and Oregon. Fish Commission
Abstract:: "We monitored oyster mortality in Yaquina, Coos, and Tillamook bays from July 1966-March 1972. Pacific oyster (Crassostrea gigas) mortality in Yaquina Bay appears to be lower than in any other reporting area on the Pacific Coast, generally less than 2% per year. Native oyster (Ostrea lurida) mortality ranged from 9.6-28.2%....

Oyster mortality study : annual report, 1970/1971

Creator:: Gibson, Gary G., Oregon. Fish Commission, and United States. Fish and Wildlife Service. National Marine Fisheries Service
Abstract:: "Oyster mortality data collected from suspended trays at three subtidal locations in Yaquina Bay disclosed an unusually high 26.5% Pacific oyster (Crassostrea gigas) mortality during the study year. Almost all of this mortality resulted from culling damage which occurred previous to introduction of the oysters into trays. Native oyster mortality...

Osmotic and ionic regulation in a freshwater teleost, Ictalurus nebulosus (Ie sueur)

Creator:: Walker, Lester Eugene
Abstract:: Aspects of hydromineral balance in the stenohaline fresh-water catfish, Ictalurus nebulosus (Le Sueur) were studied at 10° and 20°C. Temperature did not affect water content significantly. Water content was 78 ml/100 g body weight, 32% of which is in muscle and 49% in the skeleton and associated connective tissue. The...

An evaluation in rainbow trout of biliary excretion of sulfobromophthalein and effects of biliary excretion on the toxicity of rotenone

Creator:: Schmidt, Dana C.
Abstract:: Biliary excretion has been of considerable interest in mammals but has not been extensively studied in fish. To understand the significance of biliary excretion in rainbow trout (Salmo gairdneri), two studies were conducted. The objective of the initial study was to evaluate the ability of rainbow trout to excrete a...

Analysis of age determination methods for yellowtail rockfish, canary rockfish, and black rockfish off Oregon

Creator:: Six, Lawrence D.
Abstract:: Methods and utility of age determination of yellowtail rockfish (Sebastes flavidus), canary rockfish (Sebastes pinniger), and black rockfish (Sebastes melanops) collected off Oregon during 1972 to 1975 are discussed. Structures compared on the basis of the reproducibility of counts of annuli (consistency of readings) were the anal fin pterygiophore, opercle,...

Resistance of coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri) stocks and transferrin genotypes to bacterial kidney disease and vibriosis

Creator:: Winter, Gary Wayne
Abstract:: Juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (Salmo gairdneri) of different stocks and three transferrin genotypes (AA, AC, and CC), all reared in identical or similar environments, were experimentally infected with the causative agent of bacterial kidney disease (BKD) or Vibrio anguillarum. Mortality due to the pathogens was compared...
