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.

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.

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.

This book was released on 1990-09-11 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1944-1971, the Hanford Reach of the Colombia River in Washington State received quantities of radioisotopes, heat and chemicals from up to 8 plutonium reactors. Subsequently, from 1971-1984 the same part of the river provided cooling water for 3 power-production facilities.Environmental concerns promoted a series of continuing studies to examine various potential adverse effects. No significant impairment of the rivers ecosystem was detected.This book reviews these studies and places them in a historical framework.It provides a unique overview of studies made over a 40-year period which are now scattered through various published and unpublished documents.It should be of interest to all those concerned with aquatic ecology and environmental concerns.
