This book was released on 2013 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pictured Rocks National Lakeshore (PIRO) is home to several partially migrating populations of brook trout (Salvelinus fontinalis). The presence of fluvial and adfluvial movement patterns led to a large scale study of their movement behavior and morphological characteristics. The study involved measuring and implanting brook trout with passive integrated transponder (PIT) tags beginning in 2004 within Sevenmile Creek and Mosquito River. The project used radio frequency identification (RFID) antennas at the mouth of each river to detect PIT tagged brook trout moving in and out of the streams. Electroshocking within the rivers was used to track within stream movements of brook trout. A subset of fluvial individuals in both systems was found to move the entire sampled length of each stream. A combined 53% of all fluvial brook trout were found more than 150 m from their original capture location (OCL). Brook trout density was significantly correlated to fluvial movement within Mosquito River, suggesting that density could be a stimulus for fluvial movements. Also within Sevenmile Creek 62%, of individuals were correctly assigned as fluvial or adfluvial using their OCL. Overall the lack of distinguishing characteristics between fluvial and adfluvial brook trout suggests that these life history tactics are varying degrees on a movement continuum within brook trout populations.

Available in PDF, EPUB and Kindle. Book excerpt: "Brook trout movement-related life history strategies vary considerably and range from individuals that stay within the same 100 meters their entire life to individuals that are potamodromous or anadromous. Potential drivers of movement life histories have been the subject of much research in fish, with genetic subpopulation explanations often failing to explain the phenomenon. Metabolic phenotypes have been suggested as a possible driver for expression of different movement life histories. I investigated if metabolic phenotypes are related to movement strategies within a population of brook trout (Salvelinus fontinalis) in Unnamed Creek, a tributary to the Rock River, Alger County, MI. Intermittent flow respirometry was used in the field using ambient stream water to determine metabolic phenotypes of wild trout. Individuals were then tagged with passive integrated transponders (PIT) and tracked with stationary readers and a backpack reader during the summer. Brook trout that moved over 250m displayed a significantly larger aerobic scope than individuals that moved less than 250m. Temperature effects on metabolic measures were not detected among the brook trout in this study, but this could be due to wild acclimation to a range of temperatures rather than a single value.. This study suggests that brook trout metabolic phenotypes are variable between individuals and likely relate to movement phenotype under natural field conditions."--Abstract.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydropower accounts for more than one third of Ontario Power Generation's electrical production. Hydroelectric development often occurs on rivers that also support recreational fisheries. The construction and operation of dams, diversions and generating facilities unavoidably influence the ecological function of rivers. The Aguasabon River is a northern Canadian Shield river with major developments for water diversion, storage, and power generation. This river offers opportunity to examine the importance of vertical flows through the substrate at a Brook Trout (Salvelinus fontinalis) spawning area. The vertical and horizontal hydraulic gradients and subsequent water temperature changes are the subject of this study. Piezometers were used to monitor the river and subsurface water levels near Brook Trout redds during the spawning and incubation period under normal and increasing discharge conditions. The Brook Trout spawning area in the Aguasabon River experienced upwelling conditions for the entire monitoring period (Oct 28th, 2016 - Jan 13th, 2017) before water release at the Long Lake Control Dam (LLCD). Hyporheic temperatures declined gradually, remaining >3.7 °C. The river temperature in the winter before water release was 1.5 °C. Rapid increase in water level after discharge from above the LLCD resulted in the reversal of flow in the hyporheic zone. Negatives values of vertical and horizontal gradients occurred for up to 30 h between surface water and hyporheic water up to 1.8 m below the river substrate. The water temperature in all piezometers decreased in unison with water release. Shallow inshore piezometers showed the greatest change, ˃53 h at 1 °C, compared to both shallow and deep offshore piezometers, which never fell

This book was released on 2013 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winter salmonid studies are becoming more common due to the importance of this time period on survivorship and the growing concern of climate change. Fish condition, fish movement, aquatic invertebrate drift, and available habitat were assessed in Sevenmile Creek, located in Pictured Rocks National Lakeshore, during the winter months to determine the effects on brook trout. Mean fish condition was shown to decrease during winters for both 100+ mm BKT (12.7--17.6%) and sub-100 mm BKT (7.9--10.6%). Aquatic invertebrate drift decreased during winter, relative to summer, in both abundance (37.2-- 48.0%) and richness (25.8--28.8%). Riffles, runs and pools were assessed to determine habitat suitability for brook trout. During the summer months, water velocity and depth remained generally stable; however, during winter months, as ice formed, water depth fluctuated as much as 49.5% in pools and 16.5% in runs, and velocity varied up to 23.0% in runs, suggesting a decrease in available suitable habitat for brook trout in winter. Also, radio-telemetry data suggested post-spawn movements of brook trout that were followed by a period of relatively little movement through mid-winter. The results show that winter is a challenging period for brook trout in this Upper Peninsula stream and suggests that limitations in habitat availability may play a role in overwintering success.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The rapidly increasing temperatures of aquatic systems associated with climate change represent a novel threat to populations of brook trout (Salvelinus fontinalis), and much uncertainty remains about the potential of these populations to acclimate, adapt, or compensate for such changes. Brook trout are considered stenothermal, with a thermal preference of 14°C to 18°C, and a critical thermal maximum of 25°C. With such narrow thermal optima, brook trout are restricted to watersheds with adequate thermal refugia to withstand warm summer temperatures. For cold-adapted species such as brook trout (Salvelinus fontinalis), the long-term success of the species will depend on its ability to cope with, and adapt to, rapidly changing thermal conditions. The current study evaluated growth patterns of young-of-the-year brook trout in two tributaries with dramatically different annual thermal regimes. Using a common garden design, we then evaluated the effect of variable incubation temperatures on egg size, developmental phenology, yolk sac allocation, hatch timing, and size at hatch under laboratory conditions. The results of the current study provide evidence for plasticity in the developmental response of brook trout to withstand moderate effects of climate change. The results of the field studies demonstrated wide variability between populations, individuals, and cohorts. Laboratory studies suggested that population differences were largely mitigated by the effect of the environment, and that incubation conditions appeared to have a strong moderating effect on population differences in early development."--Abstract.

Book excerpt: Early developmental stages of cold-adapted ectotherms such as brook trout (Salvelinus fontinalis) are atrisk of mortality with increasing water temperatures because of their sensitivityto changes in their environment.I studiedthe mass and routine metabolic rate(RMR) of wild-origin brook trout eggs, alevin and young fry reared at normal (5°C) and elevated (9°C) temperaturesfor the duration of the study or at mismatched temperatures.This setup determinedif preconditioning acclimation for one temperature benefits or hinders the organism later in life.Three levelsof biological organization (ancestry, population, family) were studied using Akaike?sInformation Criterion (AIC) to identify models that best accountedforvariation in thedata.Family, massand temperature were most important inpredictingbody mass and mass-adjustedRMR, although population and ancestral-level differences were also detected atsome life stages.Strongvariation in body mass and mass-adjusted RMRamong families may indicate adaptive potential within brook trout populations to respond to increases in water temperaturewithclimate change.Keywords: Temperature, physiology, brook trout, Salvelinus fontinalis, thermal tolerance, acclimation, routine metabolic rate, environmental matching, AIC.
