“…The two sampling locations in this study join at a confluence and sampling was done 150 m upstream of this confluence in both streams. Previous studies in this area demonstrated that this species travels very little between the two adjoining streams (Bliss et al 2015). This particular combination of movement and location permitted testing of how habitat quality plays a role in subsequent responses to a standardized stressor while controlling for factors such as weather events, temperature, etc.…”

“…This particular combination of movement and location permitted testing of how habitat quality plays a role in subsequent responses to a standardized stressor while controlling for factors such as weather events, temperature, etc. Habitat quality is a complex idea but in this context Kizell Drain was considered to be the more degraded system due to lower levels of sinuosity, habitat complexity, cover, and types of sediment (Goldstein and Meador 2005;Walsh et al 2005;Bliss et al 2015).…”

“…Hontela et al 1992;Norris et al 1999). This experiment tested the hypothesis that the central mudminnow population collected from Kizell Municipal Drain, a more disturbed stream (Bliss et al 2015), would display higher baseline GC levels and lower maximum GC levels than the population collected from Watts Creek, a relatively less disturbed stream.…”

“…The watershed is largely located in a stretch of the National Capital Commission (NCC) greenbelt area and consists of Watts Creek and the Kizell Municipal Drain, tributaries of the Ottawa River. Kizell Drain receives stormwater runoff from the Kanata area and is less sinuous, narrower, shallower, and has less in-stream structure than Watts Creek (Maarschalk-Bliss, 2014;Bliss et al 2015). Due to these differences, Kizell is considered to be the more disturbed habitat when compared with Watts (Goldstein and Meador 2005;Bliss et al 2015).…”

While work has been done by Bliss and colleagues (2015) to observe the current conditions of the watershed through fish movement and assemblage, there have not been studies on the difference in individual condition between Watts Creek and Kizell Drain.…”

DedicationFor my amazing and remarkable family. To my little brothers who always remind me what it means to be responsible, my younger sister who is the most doting partner in crime, and my older sisters who are the most sympathetic confidents. To my mother who has taught me the meaning of hard work and selflessness through example. You never once deny me assistance in my studies or admit you are too busy to go through my notes with me, even though I know you are. To my father who has always been the silent onlooker, yet calm and consistent rock when everyone else is stressing out. When I have nowhere else to go for help, you are always there waiting patiently on the sidelines. Lastly, to my husband Brad: I have required an inhuman amount of patience, understanding, and cheering up in these long two years we have had alone and you have exceeded my expectations. You are what keeps me going when I think I have had enough.iii AbstractAs wild animals are encountering a rapidly changing world, it is of increasing importance to understand the behavioural and physiological responses associated with these environmental stressors. There are many factors that can potentially influence glucocorticoids (GCs) and the stress response including habitat quality, conspecific density and season which were studied in this thesis. I used freshwater fish to examine how these factors were associated with baseline, maximum and responsiveness of cortisol, the primary GC in teleost fish. Using pumpkinseed (Lepomis gibbosus) collected from limnetic and littoral habitats I tested whether glucose and cortisol baseline, maximum, and responsiveness concentrations varied relative to habitat complexity (i.e. from no substrate or vegetation to a mixture of substrate and various degrees of vegetative cover) and conspecific density experienced following a standardized air stressor.Overall, habitat complexity and conspecific density had no significant effect on the GC stress response but during the habitat experiment the fish collected from the littoral site had significantly higher concentrations of maximum glucose, glucose responsiveness, and maximum cortisol levels. Using central mudminnow (Umbra limi) collected from two nearby streams differing in habitat quality, I tested whether baseline and maximum cortisol levels varied relative to habitat quality and season. Overall, habitat quality had no significant effect on baseline or maximum cortisol levels but there was a significant difference across seasons. The results of this study identify ecological correlates of GC concentrations in wild freshwater fish. Specifically, this body of work indicates that polymorphism and season should be taken into consideration for stress-related studies. Moreover, the lack of association of GCs in fish samples from habitats of differing quality emphasizes that human-perceived differences in habitat quality may not yield individual-level differences in stress. iv Acknowledgements I would like to thank my supervisor, S.J. Cooke, for much guidance, feedback and su...

Behavior and Survival of Stocked Trout in Southern Appalachian Mountain Streams

et al. 2018

Stocking of trout to support recreational fisheries is a common practice among state and federal agencies to meet angling and harvest demands. Success of stocking efforts relies upon fish behavior and survival to maximize the availability of fish to anglers. We quantitatively described the movement behavior and survival of stocked Brook Trout Salvelinus fontinalis, Brown Trout Salmo trutta, and Rainbow Trout Oncorhynchus mykiss in three southern Appalachian Mountain streams in western North Carolina, USA, that were managed under delayed harvest regulations. Hatchery trout were tagged with a combination of PIT tags and radio transmitters (radio tags); stocked into "Delayed Harvest Trout Waters" of the North Toe, East Prong Roaring, and Little rivers; and monitored during the catch-andrelease season from October to June. Assessed according to river and species, 19-65% of trout emigrated from the delayed harvest study reaches, while 1-29% died within the reaches. The majority of radio-tagged fish (71%; 59-85% by river) remained within 2 km of the stocking location, whereas 6% migrated over 10 km from the stocking location. Few trout stocked during fall (October and November) were available to anglers the following June due to a combination of migration and mortality. Emigration from delayed harvest study reaches was associated with stocking and highflow events. Multi-state modeling detailed these observations with weekly estimates of migration and survival rates. River-specific differences in emigration and mortality suggested that emigration was a greater source of trout loss than mortality in all rivers; no pattern related to river size was apparent in emigration, but mortality was greater in small streams. Brook Trout mortality rates were highest among the three species, and large fish of most species showed higher emigration and mortality than catchable-sized trout. Fisheries managers can apply our results to alter stocking regimes so as to enhance the efficiency of stocking and the acclimation of stocked trout to instream environments.
