Anaesthetic drugs are commonly administered to fish in aquaculture, research and veterinary contexts. Anaesthesia causes temporary absence of consciousness and may reduce the stress and/or pain associated with handling and certain invasive procedures. The rainbow trout (Oncorhynchus mykiss) is a widely-used model species with relevance to both aquaculture and natural ecosystems. This study sought to establish the relative acute impact of commonly used anaesthetics on rainbow trout when used for anaesthesia or euthanasia by exploring their effects on aversion behaviour and stress physiology. Five widely used anaesthetics were investigated at two concentrations reflective of common laboratory practises: MS-222, benzocaine, 2-phenoxyethanol, …

Graduate Theses, Dissertations, and Problem Reports
Research suggests that many veterans with post-traumatic stress disorder (PTSD) struggle with reintegration (Sayer et al., 2010), but are unlikely to seek help or complete treatment (Schottenbauer et al., 2008). To make matters worse, available treatment options are often time consuming, challenging, and/or associated with negative side effects (Carafano & Hutchinson, 2017). Using animals as a treatment modality for veterans with PTSD is an emerging topic of interest and has shown promise (Owen, et al., 2016; Richie et al., 2016). However, several factors have hindered the advancement of this field. Obstacles include a lack of standard terminology and classification system, …

Flooring And Driving Conditions During Road Transport Influence The Behavioural Expression Of Cattle, Catherine A. Stockman, Teresa Collins, Anne L. Barnes, David Miller, Sarah L. Wickham, David T. Beatty, Dominique Blache, Françoise Wemelsfelder, Patricia A. Fleming
Flooring And Driving Conditions During Road Transport Influence The Behavioural Expression Of Cattle, Catherine A. Stockman, Teresa Collins, Anne L. Barnes, David Miller, Sarah L. Wickham, David T. Beatty, Dominique Blache, Françoise Wemelsfelder, Patricia A. Fleming
Françoise Wemelsfelder, PhD
This study examined whether observers could distinguish between cattle that were exposed to various road transport conditions: Experiment 1 compared a manipulated flooring treatment (non-grip flooring, NG) with a control transport event (grip flooring, G) and Experiment 2 compared a manipulated driving style (stop-start driving, SS) with a control transport event of smooth, continuous (C) driving. The behavioural expression of cattle was assessed through the process of Qualitative Behavioural Assessment (QBA), and these assessments were tested for correlation with various physiological parameters. Fourteen Angus steers were assessed. Blood samples were collected immediately before and after transport, and heart rate and …
Qualitative Behavioural Assessment And Quantitative Physiological Measurement Of Cattle Naïve And Habituated To Road Transport, C. A. Stockman, T. Collins, A. L. Barnes, D. Miller, S. L. Wickham, D. T. Beatty, D. Blache, F. Wemelsfelder, P. A. Fleming

Françoise Wemelsfelder, PhD
The present study examined whether observers could distinguish between cattle that are naïve to road transport and the same cattle after becoming more habituated to transport. The behavioural expression of cattle was assessed through the method of qualitative behavioural assessment (QBA), and these assessments were correlated with various physiological parameters. Fourteen Angus steers were assessed during their first road trip and then again on their ninth trip, 15 days later. Blood samples were collected immediately before and after transport, and heart rate and core body temperature were measured continuously throughout each trip. Video footage recorded during each trip was edited …
Laboratory Routines Cause Animal Stress, Jonathan P. Balcombe, Neal D. Barnard, Chad Sandusky
Laboratory Routines Cause Animal Stress, Jonathan P. Balcombe, Neal D. Barnard, Chad Sandusky
Jonathan Balcombe, PhD
Eighty published studies were appraised to document the potential stress associated with three routine laboratory procedures commonly performed on animals: handling, blood collection, and orogastric gavage. We defined handling as any non-invasive manipulation occurring as part of routine husbandry, including lifting an animal and cleaning or moving an animal's cage. Significant changes in physiologic parameters correlated with stress (e.g., serum or plasma concentrations of corticosterone, glucose, growth hormone or prolactin, heart rate, blood pressure, and behavior) were associated with all three procedures in multiple species in the studies we examined. The results of these studies demonstrated that animals responded with …
Stress And Reproductive Hormones In Grizzly Bears Reflect Nutritional Benefits And Social Consequences Of A Salmon Foraging Niche, Heather M. Bryan, Chris T. Darimont, Paul C. Paquet, Katherine E. Wynne-Edwards, Judit E. G. Smits
Stress And Reproductive Hormones In Grizzly Bears Reflect Nutritional Benefits And Social Consequences Of A Salmon Foraging Niche, Heather M. Bryan, Chris T. Darimont, Paul C. Paquet, Katherine E. Wynne-Edwards, Judit E. G. Smits
Physiology Collection
Physiological indicators of social and nutritional stress can provide insight into the responses of species to changes in food availability. In coastal British Columbia, Canada, grizzly bears evolved with spawning salmon as an abundant but spatially and temporally constrained food source. Recent and dramatic declines in salmon might have negative consequences on bear health and ultimately fitness. To examine broadly the chronic endocrine effects of a salmon niche, we compared cortisol, progesterone, and testosterone levels in hair from salmon-eating bears from coastal BC (n = 75) with the levels in a reference population from interior BC lacking access to salmon …
A Non-Invasive Assay For Monitoring Stress Responses: A Comparison Between Wild And Captive-Reared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Sinan Ali, Culum Brown
A Non-Invasive Assay For Monitoring Stress Responses: A Comparison Between Wild And Captive-Reared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Sinan Ali, Culum Brown
Aquaculture Collection
The stress response of wild and captive reared rainbowfish (Melanoteania duboulayi) following chasing by a simulated predator was examined. Cortisol release rate was monitored using a flow through system by measuring water borne hormone levels. Tests using known cortisol concentrations revealed that the technique yielded 95% of the cortisol present in the water. Cortisol release rates increased several fold in both populations after being chased but peaked at different time periods. Wild fish showed a typical stress response with release rate rising to (2.29±0.22 ng g−1 h−1) 2 h after exposure followed by rapid recovery. The captive-reared …
