Effects of inbreeding Coho salmon (oncorhynchus kisutch)

Creator:

Solazzi, M. F. (Mario Frank)

Abstract:

Effects of inbreeding coho salmon (Oncorhynchus kisutch) on survival during early life history, growth, feed efficiency, and resistance to gas bubble disease were studied. No effect of inbreeding could be associated with either F=0.25 or F=0.125. Tetraploidy may help explain the absence of inbreeding depression at these levels.

Masters Thesis
Biochemical genetic variation among selected populations of chinook salmon (Oncorhynchus tshawytscha) in Oregon and Washington

Creator:

Kristiansson, Anne Christine

Abstract:

Biochemical variation in 12 different chinook populations, sampled from 10 hatcheries along the Columbia River and the Oregon coast, was studied with starch gel electrophoresis. An index was used to describe the genetic differences between pairs of populations. Differences were observed between spring and fall chinook and between Columbia River...

Genetic aspects of lead toxicity in laboratory populations of guppies (Poecilia reticulata)

Creator:

Burger, Carl V.

Abstract:

The heritability of resistance to death from the effects of lead in laboratory guppy populations was determined from comparisons between progeny produced in a nested breeding experiment and from mass selection experiments. Resistance was measured by the time to death. Heritabilities of resistance to lead were estimated to be 0.26...

The heritability of resistance to gas bubble disease of Columbia River fall Chinook salmon, (Oncorhynchus tshawytscha)

Creator:

Cramer, Steven P.

Abstract:

A nested mating experiment in which 20 males were each mated to four different females was used to obtain an estimate of the heritability of resistance to death from gas bubble disease in Columbia River fall chinook salmon (Oncorhynchus tshawytscha). Heritability estimates ranged from 0. 037 to 0. 038. Bioassays...

Masters Thesis
The feasibility of a consumptive wild trout sport fishery on the North Fork of the Middle Fork of the Willamette River

Creator:

Nicholas, Jay W.

Abstract:

The objective of this study was to determine whether wild populations of trout in the North Fork of the Middle Fork of the Willamette River can support a catch rate of 0.3-0.5 trout per hour at current levels of effort and to predict how different size and bag limits would...

Factors influencing the life history of spring chinook salmon (Oncorhynchus tshawytscha) spawning in the Columbia River watershed from 1960 to 1977

Comparative behavior of the progeny of hatchery and wild steelhead trout (Salmo gairdneri)

Creator:

Bieber, Glen F.

Abstract:

The objectives of this study were to determine whether changes in the selective pressures which occur in a hatchery could cause inherited modifications in the behavior of steelhead trout (Salmo gairdneri) that would affect their survival in the wild. Environmental effects on the behavior of the offspring of hatchery and...

Masters Thesis
Influence of marine environment on age and size at maturity, growth, and abundance of chum salmon, Ohcorhynchus keta (Walbaum), from Olsen Creek, Prince William Sound, Alaska

Creator:

Helle, John H.

Abstract:

Effects of the marine environment on age and size at maturity, early marine growth, and abundance of chum salmon, Oncorhynchus keta, were studied at Olsen Creek during 1959-77. Chum salmon returned to Olsen Creek as predominately 3-, 4-, and 5-year fish; however, age composition varied from year to year. The...
