This book was released on 2006 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: I evaluated losses of trout to irrigation canals and studied the annual movement patterns of Bonneville cutthroat trout Oncorhynchus clarkii utah in a high plains Rocky Mountain watershed. My objectives were to (i) evaluate the magnitude of fish loss from a basin-wide perspective to assess the population-level consequences of canal entrainment and (ii) document and compare seasonal movement patterns and mortality rates of adult cutthroat trout among complementary habitats. I found that a small percentage of cutthroat trout (1.2--3.3%) and brown trout (0.4--1.2%) were entrained in irrigation canals. These values were small relative to total annual mortality rates for inland riverine cutthroat trout (57.1%) and brown trout (53.3%) in the Rocky Mountain region of the United States. Placing the number of entrained fish in context with the basin-wide population and total annual mortality rates provides a means to evaluate the significance of fish entrainment losses to irrigation canals. I found that cutthroat trout utilized complementary habitats throughout the drainage. In the spring, cutthroat trout migrated upstream during runoff (median distance 37.1 km) and 62% of the total annual mortality occurred during this time. After spawning in the headwaters of the river system, fish moved downstream during the summer and fall a median of 11.6 km; 23% of the total annual mortality occurred over this time interval. During the winter, fish remained relatively sedentary (median movement 0.1 km) and experienced low mortality (16% of the total annual mortality). The data provide support for conceptual models that emphasize the importance of habitat complementarity as a major factor influencing movement patterns in riverine fishes. Large-scale movement is an important part of the life history of Bonneville cutthroat trout in the river system. Maintaining connectivity throughout the system is an integral component to the management and conservation of this species.

Book excerpt: "The Colorado River cutthroat trout (Oncorhynchus clarki pleuriticus) historically occupied portions of the Colorado River drainage in Wyoming, Colorado, Utah, Arizona, and New Mexico. Today this subspecies only occupies a fraction of its historical range is primarily located in small headwater streams. Colorado River cutthroat trout is a category 2 species (one that may be appropriate for listing as threatened or endangered) by the USDI Fish and Wildlife Service and is considered a sensitive species by Region 2 of the Forest Service. This conservation strategy is a continuation of efforts started in 1987 under a comprehensive management plan for Colorado River cutthroat trout in Wyoming"--Page ii.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In many cases of accidental isolation, the populations above the barriers have limited habitat and small population sizes that make them vulnerable to extinction and may hold evolutionary value to the species as a whole. All the isolated populations in the drainage currently have high genetic differentiation among tributaries, low genetic diversity within each tributary, a suggestion of isolation by distance, and effective population sizes that are below the recommendation for long- term persistence. This structure represents natural and anthropogenic influences, but the presence of the human-constructed barriers in the headwater tributaries puts the larger core conservation group at risk into the future. Although the genetic diversities within the populations are low, the high genetic differentiations among populations suggest that each population may have its own unique contribution to the evolutionary value to the drainage as a whole and each is important to conserve into the future.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. 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.
