Fatty acids of exercised and non-exercised salmon

Creator:: Saddler, James Bryan
Abstract:: The fatty acids of coho salmon were identified and then a study was conducted to determine the effects of exercise on the fatty acids of salmon forced to swim against water velocities of 52, 54, 56, and 59 cm/sec, The shorter and lighter salmon were less competent at a given...

Changes in the swimming performance, behavior and physiology of juvenile chinook salmon (Oncorhynchus tshawytcha) after exposure to one, two or three acute handling stresses

Creator:: Sigismondi, Linda A.
Abstract:: The performance of an organism or organismic subsystem is the result of the interaction between the performance capacity of the system and Its environment. Environmental conditions can stress an organism and thus affect it's performance. In this study, three whole organism performances were examined: critical swimming speed, fatigue time and...

Quantitative genetics of chum salmon, Oncorhynchus keta (Walbaum)

Creator:: Smoker, William Williams
Abstract:: Chum salmon from different stocks were bred together in two experiments. Three stocks contributed gametes to one experiment, two stocks to another. Sibling groups of eggs, alevins, and fry were maintained in a common environment. Variability of development rates, rearing performance, susceptibility to disease, and behavioral traits was partitioned into...

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...

Evaluation of a louver guidance facility used to sample salmon and trout emigrants

Creator:: Holubetz, Terry Bruce
Abstract:: The subject of this thesis is an evaluation of a louver facility in the Lemhi River, Idaho. The louver facility was designed to guide juvenile chinook salmon and steelhead trout into a trap in order to sample downstream migrant populations. The study was designed to determine: (1) if the catch...

Elevated temperature and the production of juvenile Chinook salmon (Oncorhynchus tshawytscha) in a model stream

Creator:: Bisson, Peter Andre
Abstract:: Temperature was elevated approximately 4° C in a model stream relative to an unheated, but otherwise similar control stream. The streams were located outdoors, received identical amounts of exchange water from a nearby creek, and followed natural diurnal and seasonal temperature cycles Juvenile spring chinook salmon (Oncorhynchus tshawytscha) were introduced...

A phenotypic comparison of thirty-eight steelhead (Oncorhynchus mykiss) populations from coastal Oregon

Creator:: Hatch, Keith Martin
Abstract:: An aspect of the genetic structure of coastal Oregon steelhead was explored and found to gradually change in a north to south pattern for the allelic frequencies of several enzymes. Isocitrate dehydrogenase and superoxide dehydrogenase were the clearest examples of this pattern of variation. This pattern was most evident in...

Rearing conditions and their effects on growth, food conversion, and survival of English sole (Parophrys vetulus Girard)

Creator:: Williams, Steven Frank
Abstract:: This study consisted of determining some of the conditions for culture of young English sole (Parophrys vetulus Girard) in the laboratory. Rearing of the larvae to the juvenile stage was attempted unsuccessfully; techniques used and problems encountered during culture are discussed. Growth of juveniles was studied at combinations of temperatures...
