Racial identification of chinook salmon (Oncorhynchus tshawytscha) and juvenile steelhead trout (Salmo gairdneri)

Creator:: Martin, James T.
Abstract:: Efforts to manage stocks of salmonids in Pacific Northwest stream systems are complicated by the occurrence of several runs of a species thought to represent races rearing sympatrically as juveniles. In order to collect the population statistics needed to properly manage these stocks, managers need a method of identifying juvenile...

Phenotypic comparison of hatchery and wild coho salmon (Oncorhynchus kisutch) in Oregon, Washington, and California

Creator:: Hjort, Randy Carl
Abstract:: Phenotypic similarities of coho salmon (Oncorhynchus kisutch) stocks from Oregon, Washington, and California were compared using agglomerative and divisive cluster analyses. The phenotypic characters evaluated included the following: 1) the isozyme gene frequencies of transferrin and phosphoglucose isomerase; 2) the life history characters time of peak spawning and proportion of...

The adaptive significance of certain enzyme polymorphisms in steelhead trout (Salmo gairdneri)

Creator:: Redding, Joseph Michael
Abstract:: Mean weights, lengths, and condition factors of three isozyme phenotypes of lactate dehydrogenase (LDH) enzyme differed significantly for experimentally reared winter steelhead trout (Salmo gairdneri) fry. Time of emergence from the gravel was unrelated to LDH phenotype. Relative mortality of the phenotypes between eyed-egg stage and emergence was unaffected by...

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...

Chemoreception in coho salmon (Oncorhynchus kisutch) : aspects of behavior, physiology, and toxicology

Creator:: Rehnberg, Bradley Glenn
Abstract:: Detection of L-serine and D,L-alanine by juvenile coho salmon (Oncorhynchus kisutch) was measured in a two-choice Y-trough. Threshold concentration for olfactory detection of L-serine was 10-8 M for zero-age parr, 1O-7 M for yearling parr, 10-5 M for smolts in late April-early May, and 10-6 M for smolts in June....

Hormonal and osmoregulatory aspects of smoltification in coho salmon, Oncorhynchus kisutch

Creator:: Specker, Jennifer Lee
Abstract:: Coho salmon smolts (Oncorhynchus kisutch) were transported at low and high densities. (12 and 120 g/L) for short and long periods (4 and 12 h). Because smolts can be transplanted directly to seawater, half of the fish in each treatment were transported to tanks containing seawater and half to tanks...

Influences of environmental acidification on salmonid reproduction

Creator:: Weiner, Gary S.
Abstract:: Reproduction of salmonid fishes in acidic water was studied using the rainbow trout (Salmo gairdneri). Adult trout were exposed to various levels of hydrogen ion (pH levels 4.5, 5.0, 5.5, and control [6.5 to 7.1]) during the final 6 weeks of reproductive maturation. Reduced survival rates of the progeny of...
