Book excerpt: Movement patterns and habitat use of Bonneville cutthroat trout (Oncorhynchus clarki Utah) in tributaries of the Logan River watershed are greatly affected by habitat alterations created by North American Beaver (Castor canadensis). Evaluation of cutthroat trout habitat use in these watersheds is also complicated by biotic interactions with invasive brown trout (Salmo trutta) and brook trout (Salvelinus fontinalis). My objectives in this thesis were to 1.) Evaluate the passage of beaver dams by each trout species in the Temple Fork watershed and 2.) Evaluate the habitat use of cutthroat trout in the presence of brown trout and brook trout over a range of spatial scales. To address these objectives, 1381 trout were tagged with passive integrated transponder tags. Their locations were recorded using a combination of annual capture/recapture surveys, stationary in-stream antennas, and monthly continuous mobile antenna surveys. To address objective 1, sh were located above and below 22 beaver dams to establish whether sh passed dams and to identify downstream and upstream passage; 187 individual trout were observed making 481 passes of all 22 beaver dams. Native Bonneville cutthroat trout passed dams more frequently than both non-native brown trout and brook trout. It was determined that spawning timing affected seasonal changes in dam passage for each species. Physical characteristics of dams such as height and upstream location affected the passage of each species. Movement behaviors of each trout species were also evaluated to help ex- plain dam passage. These data suggest beaver dams are not acting as barriers to movement for cutthroat and brook trout but may be impeding the movements of invasive brown trout. To address objective 2, a hierarchical classification of stream habitat was created using the River Styles framework. The River Styles framework not only establishes a relationship between habitats at dierent scales, but also attempts to understand the processes that create and maintain those habitats. The location of each sh observation was associated with habitats at the stream, landscape unit, River Style, and geomorphic unit levels. Habitat use of each species of sh was evaluated at each spatial scale using all sh observations over the four-year study period. Hotspot locations, or locations used consistently by a species of sh consistently through time, were also evaluated across the entire study period and over each year. It was found that brook trout almost exclusively use the beaver ponds and beaver-altered habitats in Spawn Creek. Brown trout were not found in the upper- most parts of both Spawn Creek and Temple Fork. They were also found more than the other species in pools created by bedrock or man-made control features, suggesting that they select highly stable habitats. Cutthroat trout were found more than brown trout in beaver-altered habitats and lateral scour pools, suggesting that they select more dynamic, naturally occurring habitats.

This book was released on 2014 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Populations of anadromous brook trout can be found from northern Canada into New England. It is believed that the extent of anadromy exhibited by coastal brook trout populations decreases with latitude, but the ecology and movements of the more southern populations are less studied. A 33-month acoustic telemetry study of anadromous brook trout (Salvelinus fontinalis) was conducted in a restored coastal stream and adjacent marine system in southeastern Massachusetts. Movement and migration patterns of 54 brook trout were investigated for individual differences and common features. Individuals exhibited a range of movement patterns. Some were more resident and only moved short distances, while others moved great distances covering the entire stretch of the stream (7.25 km) and moving into the marine environment. General Additive Mixed Models revealed that date was the major influence on brook trout movement between habitats and predicted peaks in movement in the spring and fall. Downstream movement peaked in the spring and in the fall, suggesting post-spawning feeding migration. Fish transitioned between habitats more often at new and full moons and when stream temperature was between 8 and 12 °C. Upstream transitions peaked as temperatures declined in winter 2011. Fifty percent of tagged brook trout were detected in the estuary during the study, suggesting that it is an important habitat for the population. In summer 2012, 14 tagged brook trout (20% of active tags) resided near one receiver at the head of the tide, which contained a thermal refugium in the form of a cold-water spring seep. Of the 84 tagged brook trout, 9.5% moved to the marine environment. Warm temperatures in saline Buttermilk Bay in the summer and cold temperatures in winter probably discourage some individuals from entering the marine environment. Compared to more northern coastal populations of brook trout, the Red Brook population appears to be less anadromous.

Book excerpt: Abstract : The coaster brook trout is a life history variant of the brook trout (Salvelinus fontinalis) that is characterized by either lake residency or migration between stream and lake habitats. Coaster brook trout were once widespread throughout Lake Superior and its tributaries, but populations declined sharply in the late 19th and early 20th centuries. Historically, brook trout were a popular target of recreational and subsistence fishing in the Lake Superior basin, and it has been hypothesized that angling pressure combined with multiple forms of industrial development are what drove the coaster brook trout's decline. In the mid to late 19th century, the logging, lumbering, and mining industries proliferated rapidly, along with the network of railroads, which provided connectivity for industry and access to once remote fishing locations. However, it is unknown to what degree each of the proposed factors influenced the coaster's decline. In Chapter 1, we collected and analyzed historical data (Pre 1880-1950) on the distribution & abundance of brook trout in Lake Superior tributaries, along with historical data on the development and expansion of industries around Lake Superior to examine potential associations between specific anthropogenic impacts and coaster brook trout declines. The data were separated into four temporal categories (Pre 1880-1880, 1881-1900, 1901-1920, 1921-1950) to examine reports of brook trout catches during critical time periods in industrial developments around Lake Superior. We performed a geospatial analysis using ArcGIS Pro that demonstrated a decrease in both putative coaster brook trout abundance and range over time. Brook trout decreased notably between the '1881-1900' time period and the '1901-1920' time period, following large increases in both lumber mills and kilometers of railroad. We performed a principal component analysis to reveal potential associations between variation in industrial variables and brook trout abundances in watersheds between the first and final time periods (Pre 1880-1880 & 1921-1950, respectively). Our analysis showed that the majority of watersheds analyzed experienced a decrease in brook trout abundance and suggested that the industrial development variables we examined all are associated with and thus may have all influenced brook trout decline, though to varying degrees, as some developments were highly localized. Angling appears to be an important factor in the decline of brook trout populations around Lake Superior, as active angling (noted removals of brook trout) occurred in every watershed for which we found data. Furthermore, brook trout populations declined almost universally, even in watersheds for which we recorded little to no industrial footprint. In Chapter 2, I examine historical and modern brook trout management initiatives, use an eco-evolutionary perspective to inform potential management & restoration strategies, and identify potential restoration watersheds using the historical GIS data from Chapter 1. I used these data to create a table of prioritized restoration sites by compiling watersheds that had both a high likelihood of historical migratory brook trout populations and also experienced little industrialization. With this information, we identified several locations in Wisconsin, Michigan, and northern Minnesota that may be optimal coaster restoration watersheds.

Book excerpt: Radiotelemetry was used to study the seasonal movements and habitat use of adult westslope cutthroat trout Oncorhynchus clarki lewisi in Roberts Creek and Rail Creek, headwater tributaries of the John Day River, Oregon, from September 2000 to December 2001. The objectives were to (1) describe adult cutthroat trout life history in headwater streams by comparing seasonal movement patterns, and (2) assess seasonal habitat selection by comparing habitat use to availability. For seasonal comparison, only fish that survived with an active transmitter throughout winter, spring, and summer were used in the analysis. Sample size was 17 (mean fork length, 241mm) on Roberts Creek and 9 (mean fork length, 252 mm) on Rail Creek. In winter and summer, radiotagged fish were relatively sedentary on both Roberts Creek (median home ranges, 35 and 104 m, respectively) and Rail Creek (median home ranges, 104 and 112 m). In spring, 65% of fish in both streams moved over 100 m upstream to spawn; upstream movements were as long as 1,138 m (median, 271 m) on Roberts Creek and as long as 3,771 m (median, 311 m) on Rail Creek. Postspawning movements downstream were common; 82% of fish on Roberts Creek and 57% on Rail Creek showed homing behavior, returning in summer to the same channel unit they inhabited in winter. Fish length was positively correlated to total movement distance in spring on Roberts Creek but not on Rail Creek. Over 86% of the surface area of both creeks consisted of fast-water channel units. Instream large wood created the majority of habitat heterogeneity in both streams and radiotagged cutthroat trout were strongly associated with large wood pools throughout the year. Plunge pools were positively selected throughout the year on both streams. Headwater-resident populations of cutthroat trout are often considered nonmigratory; however, these radiotagged fish showed fluvial migratory behavior. These results demonstrate that habitat heterogeneity and connectivity are important life history requirements for fluvial headwater resident cutthroat trout.
