Gene expression in the liver of rainbow trout, Oncorhynchus mykiss, during the stress response

Creator:: Momoda, Tracey S.
Abstract:: The extent to which responses to stress are maladaptive or adaptive to the long-term survival of fish remains to be better understood. The aim of this study was to identify differentially expressed genes in the livers of rainbow trout, Oncorhynchus mykiss, responding to an experimental stressor. Gene expression responses were...

A macroscopic to microscopic study of the effects of barotrauma and the potential for long-term survival in Pacific rockfish

Creator:: Pribyl, Alena L.
Abstract:: Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...

Interrenal and metabolic responses to stress and their modifying factors in juvenile salmonid fishes

Creator:: Barton, Bruce Alexander
Abstract:: Genetic, ontogenetic, and environmental factors modified characteristic interrenal and glycemic responses to stress in juvenile salmonid fishes. During continuous confinement stress, plasma cortisol rose more quickly in chinook salmon, Oncorhynchus tshawytscha, acclimated to high rather than medium or low temperatures; hyperglycemia following either acute or chronic stress was also highest...

Effects of o,p'-DDE on the immune system of juvenile chinook salmon (Oncorhynchus tshawytscha)

Creator:: Milston, Ruth Helen
Abstract:: Environmental factors such as chemical contamination can have immunomodulatory effects on the immune response of fish and may be contributing to the decline in salmonid populations by augmenting disease susceptibility. Xenobiotics can interfere with the immune system at several levels of complexity, and different immune cells and processes have variable...

Central control of locomotor activity in juvenile salmonids : the role of corticotropin releasing hormone in the brain

Creator:: Clements, Shaun
Abstract:: The present study investigated the neurocrine and neuroendocrine control of locomotor activity, habitat choice, social behavior, and migratory behavior in juvenile chinook salmon (Oncorhynchus tshawytscha). This was achieved by the manipulation of three neurotransmitter systems; serotonin (5-HT), dopamine (DA), y-amino-n-butyric acid (GABA) and the neuropeptide corticotropin-releasing hormone (CRH). Chemicals were...

The use of molecular biological methods to assess the effects of endocrine disrupting chemicals and natural hormones on growth in the sheepshead minnow (Cyprinodon variegatus)

Creator:: Knoebl, Iris
Abstract:: The work presented in this dissertation examines possible modes of action for growth inhibition by anthropogenic endocrine disrupting chemicals (EDCs) as well as endogenous hormones associated with growth in fish. Using the sheepshead minnow (SHM) (Cyprinodon variegatus) as a model, I developed methods to examine perturbations in the endocrine axis...

Physiological ecology of juvenile Chinook salmon (Oncorhynchus tshawytscha) rearing in fluctuating salinity environments

Creator:: Hackmann, Crystal R.
Abstract:: Estuaries provide juvenile salmonids with highly productive feeding grounds, refugia from tidal fluctuations and predators, and acclimation areas for smoltification. However, these dynamic, fluctuating salinity environments may also be physiologically stressful to growing juvenile fish. In order to evaluate the costs and benefits of estuarine marshes to juvenile Chinook salmon,...

Capture-related stressors impair sablefish, Anoplopoma fimbria, immune system function

Creator:: Lupes, Sarah C.
Abstract:: Sablefish, Anoplopoma fimbria, is a valuable North Pacific Ocean species caught in several commercial fisheries and is often discarded due to size or catch limits. Managers must account for the mortality of discarded fish to assess fish populations and harvest impacts, yet discard mortality rates of specific fisheries are generally...

Sex determination in Nile tilapia, Oreochromis niloticus: gene expression, masculinization methods, and environmental effects

Creator:: Sánchez, Wilfrido M. Contreras
Abstract:: Sex differentiation in fish is a labile process that allows sex inversion in several species. The inherent capacity of fish germ cells to differentiate into oocytes or spermatocytes constitutes a key factor allowing for functional sex inversion. This thesis set out to determine the mechanism involved in steroid-induced sex differentiation...
