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.

Book Seasonal Movement Patterns and Habitat Use of Westslope Cutthroat Trout in Two Headwater Tributary Streams of the John Day River

Starcevich and published by . This book was released on 2005 with total page 76 pages. Available in PDF, EPUB and Kindle. 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.
