Rubenson and published by . This book was released on 2019 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riverine distributions of nonnative smallmouth bass (Micropterous dolomieu) are changing in response to climate change, with smallmouth bass upstream extent increasing as temperatures warm to within its thermal tolerances. Although smallmouth bass continue to shift its distribution into new upstream habitat, little is known about the mechanisms that drive or limit distribution changes, its current distributions in the Columbia River Basin, or the potential impacts expanding smallmouth bass may have on juvenile salmonids, each of which I address in this dissertation. Like most ectotherms, each life history stage (i.e., egg, juvenile, adult) of smallmouth bass has unique thermal optimums and limits that may disproportionately affect successful establishment of new self-sustaining populations. In my first two chapters, I examined the effects of increasingly colder temperatures on spawning patterns, reproductive success, and recruitment across a broad (> 60 km) spatial extent in the North Fork John Day River. In my third chapter, I assessed the inter-annual differences in maximum upstream distribution, seasonal changes in local abundances, and seasonal movement patterns of adult bass to assess the role of adult dispersal in range dynamics. Using these data on reproduction, recruitment, and adult movement patterns, I found key behaviors and physiological constraints that limit or drive range expansion and present management strategies that may be useful to managers tasked with preventing future range expansion of smallmouth bass. In my fourth chapter, I developed a species distribution model of smallmouth bass for the Columbia River Basin using a combination of historical distribution data and environmental DNA (eDNA) distribution data collected at predicted range boundaries. Here, I found that smallmouth bass is widely distributed and predicted to overlap with 3-62% of critical salmonid spawning and rearing habitat. Under a moderate climate change scenario, I found that smallmouth bass is predicted to increase its distribution by over two-thirds, highlighting management challenges throughout the Columbia River Basin. Finally, in my fifth chapter I examine potential competition and predation dynamics in a food web that includes smallmouth bass and juvenile Chinook salmon (Oncorhynchus tshawytscha). Here, I found little evidence for a strong predation or competition threat to juvenile Chinook salmon, suggesting that although smallmouth bass is likely to increase its overlap with native salmonids, its greatest impact to salmonids appears to occur in mainstem habitats. Taken together, the five chapters of this dissertation advance the understanding of the physiology, behavior, distribution, and impact of nonnative smallmouth bass in the Columbia River Basin, which will directly contribute to the management of streams home to myriad threatened and endangered native species.

Available in PDF, EPUB and Kindle. Book excerpt: Forty radio frequency and 120 standard type Floy tags were attached to smallmouth bass to monitor their movements in connection with Columbia River water level fluctuations. Tagging information provided data on bass movement during and after their spawning period as well as their location and habitat preference. Field data indicated spawning occurred from April through June with bass leaving backwater areas and returning to the main stem of the Columbia River in August 1976 and late June 1977. River movement appeared to be related to water depth, current, and available forage. Radio-tagged fish were monitored a maximum of 61 km and Floy tags were returned by fisherman from as far as 63 km. Spawning success was estimated for White Bluffs, Hanford and F Area sloughs during 1976 and 1977 and appeared to be related to water level fluctuations. Loss of bass because of entrapment, predation, thermal or oxygen stress, and desiccation was observed in several temporary ponds.

This book was released on 1981 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallmouth bass were studied in Bull Shoals Lake to determine the nesting requirements and reproductive capabilities of the species in a reservoir. Underwater observations were conducted weekly in five study areas during the spawning seasons of 1969-76. Length of spawning season was affected by the rate of water temperature rise during the nesting period. Active nests were found at ambient temperatures of 13.3-22.5 degrees Centigrade. Nest were generally on gently sloping rock and gravel bottoms, beside permanent objects such as rocks or sunken logs, and at densities of less than one per 100 m of shoreline.

This book was released on 2012 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: We used radio telemetry to monitor the 24-h diel movement patterns of smallmouth bass (Micropterus dolomieu) in a section of the Current River, Missouri through three seasons: summer, winter and fall. Observations were made every two hours throughout a 24-h day for each season. Habitat data and depth were collected at each fish location and four random points were created at each site to determine viable habitat availability to smallmouth bass. The data determined to be the best choice model were the combination of depth and all habitat types. Using the heaviest weighted model and the odds ratio, we were able to ascertain habitat usage variations over the seasons of summer, fall and winter for smallmouth bass. Depth did not have a large influence on movement of smallmouth bass but displacement did increase slightly with fish length. Smallmouth bass movement indicated more movement during the fall and winter seasons, with crepuscular tendencies, while summer had limited movement. In the summer, smallmouth bass used open water while in the fall, they selected logs and boulders. In the winter smallmouth bass were more likely to select for boulder habitat. This study illustrates smallmouth bass actively select different cover types depending on season.

This book was released on 2018 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Smallmouth Bass Micropterus dolomieu is one of the most socially, economically, and ecologically important species in North America. The Snake River, Idaho, supports a popular Smallmouth Bass sport fishery, but little is known about the population. Additionally, anglers and Idaho Department of Fish and Game staff in the study area have expressed concern about the harvest of Smallmouth Bass associated with spawning congregations in and near the lower reaches of several major tributaries (i.e., Payette and Weiser rivers). This thesis describes the population dynamics, demographics, and movement of Smallmouth Bass in the Snake River, Idaho between Swan Falls Dam and Brownlee Dam. Results of this study indicate the population can be characterized by fast growth, good size structure and body condition, low exploitation, and highly variable movement throughout the system. Under current conditions, management changes (e.g., minimum length limit increase, seasonal fishing restrictions) in the system do not seem warranted. Furthermore, this research provides guidance for managers in the western United States where information on the distribution and ecology of Smallmouth Bass in streams and rivers is limited.

Available in PDF, EPUB and Kindle. Book excerpt: Many fish species, like salmon and sturgeon, undertake extended migrations as part of their basic behavior, and other fish and invertebrates also undertake short-term or small-scale migrations at certain phases of their life cycles. Activities such as dam construction for water supply and power generation, channelization for navigation and flood control, land drainage and wetland reclamation for agricultural and urban use all have profound impact on the aquatic ecosystem and thus on natural fish populations. Fish passes are often the only way to make it possible for aquatic fauna to pass obstacles that block their up-river journey. Based on knowledge and experience from mainly Europe and North America, this book describes the various types of fish passes, with special emphasis to "close-to-nature" solutions.
