Analysis of Immune System and Stress Parameters of Oncorhynchus mykiss in Response to Juvenile Thermal Preconditioning or Thermal-Based Parental Selection
(University of Waterloo, 2021-09-20)Higher water temperatures and pathogens are both significant factors that negatively affect the welfare of teleost fish. In aquaculture, compared to natural populations, these problems are especially exacerbated, as the ... -
Impact of the antidepressant venlafaxine on the hypothalamus-pituitary-interrenal axis function in rainbow trout
(University of Waterloo, 2014-05-27)Over the recent years, venlafaxine has become the predominant antidepressant drug detected in municipal wastewater effluents (MWWE) and aquatic systems. However, very little is known about the effect of this drug in the ... -
MicroRNAs and their role within the teleost (Oncorhynchus mykiss) stress response
(University of Waterloo, 2019-08-26)The stress response is a highly conserved signalling cascade that signals between tissues to increase energy availability. Changes in glucose regulation are studied extensively due to the glucose intolerant phenotype of ... -
Modulation of Extracellular Heat Shock Protein 70 Levels in Rainbow Trout
(University of Waterloo, 2013-01-25)At the cellular level, the stress response involves the synthesis of a highly conserved family of heat shock proteins (Hsps). These proteins are essential for maintenance of cellular homeostasis, both in times of stress ... -
Multi-stressor impacts on fish energetics and stress response: a comparison between lab and field studies
(University of Waterloo, 2017-08-24)Aquatic organisms are continuously exposed to multiple environmental stressors that work cumulatively and synergistically to alter ecosystems. The objective of this study was to investigate the impacts of multiple stressors ... -
The Role of Glucocorticoid Receptor Signaling in Zebrafish Development
(University of Waterloo, 2013-01-28)These studies present a series of novel roles for glucocorticoid signaling in the developing zebrafish embryo. The best-characterized roles of cortisol, the primary circulating corticosteroid in teleost fish, are known to ... -
Stress Physiology of Bears: Cortisol Dynamics and Identification of Novel Serum Proteins
(University of Waterloo, 2013-04-19)There is a need to understand how free-ranging animals respond and adapt to stress. However, little is currently known regarding the physiologic adaptations to stress in bears, and there are few tools available to wildlife ...
