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 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 2007 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Toward the southwestern edge of the smallmouth bass (Micropterus dolomieu) natural range, the Boston Mountains Ecoregion of Arkansas contains streams which are prone to drying during the summer due especially to hydrogeologic conditions and high evapotranspiration rates. Associated changes in habitat throughout the summer have the potential to negatively affect smallmouth bass. The objectives of this study were to characterize smallmouth bass summer habitat use and characterize changes in the extent of available habitat (velocity, depth, temperature, and substrate) throughout this potentially critical time. Study streams included the North, Middle, and East Forks of the Illinois Bayou in the Ozark National Forest. Sixty radio-transmitters (20 per stream) were surgically implanted into smallmouth bass during May and fish were tracked until October 2006. Habitat characteristics were measured three times from June-September, except substrate (assessed only once). As summer progressed, most riffle and run habitat dried completely resulting in a series of disconnected, remnant pools. Losses in wetted area of some study sections exceeded 55% of the total stream area. Smallmouth bass, in all streams and months, were consistently found at a median depth of 0.80 m. When boulder habitat was available, it was preferred; however, cobble, gravel, and bedrock substrates were also utilized. In June, smallmouth bass were found in velocities near 0.01 m/s; however, by July they were confined to remnant pools where velocity was below detection levels and water temperature occasionally exceeded 30C.

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 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A smallmouth bass habitat model was developed to estimate how changes in habitat may affect smallmouth bass populations. Habitat characteristics such as mean annual air temperature and substrate were used to determine the spatial distribution of nests, juveniles and adults throughout a lake. Growth is density-dependent for all life stages. Mortality is size-dependent in the young-of-the-year (YOY) but is set at a constant annual rate for older fish. Sensitivity analyses revealed that increases in mean annual air temperature, total dissolved solids concentration and the area available for nesting increased the density of the simulated population. Furthermore, a YOY bottleneck exists in smallmouth bass populations and the nesting habitat appears to be more important than the juvenile/adult habitat. Model predictions were compared to data from Lake Opeongo, Ontario and Long Point Bay, Lake Erie. This revealed that the model can be applied to estimate how habitat changes influence fish density but requires modification before it can be used to predict the spatial distribution of nests and fish within a lake.

Hopler and published by . This book was released on 2007 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallmouth bass (Micropterus dolomieu) were collected from a reach of the James River, Virginia undergoing American shad (Alosa sapidissima) restoration and fish passage projects. Diet and growth of these specimens were compared to specimens collected prior (1987-1990) to American shad restoration and fish passage. The Piedmont James River was stocked with >5 million American shad larvae annually since 1995 and was re-opened to migratory fish in 1999. Mean lengths-at-age (ages 1-4) were back-calculated from scales and compared using the Mann-Whitney Test. Smallmouth bass collected in 2002 had a significantly lower mean length-at-age for age 2 specimens compared to 1987-1989 smallmouth bass (P=0.04). Stomach contents were placed into four major categories (fish, crayfish, aquatic insects, terrestrial insects) and compared using Schoener's Diet Overlap Index. Schoener's Index produced a score of 0.94; indicating very high diet overlap. In 2002, Centrachidae was the dominant fish prey family and redbreast sunfish (Lepomis auritus) was the dominant species. American shad was not observed in stomach samples during 1987-1990, but was the second most common fish species prey species identified in 2002. Recovery of American shad from smallmouth bass indicates smallmouth bass are utilizing forage produced by restoration stockings. No semi-migratory fish species using new fish passage structures were recovered from smallmouth bass stomachs. Fish prey was measured by weight, number of items, and by occurrence; and placed in six family categories for comparison. Schoener's Index produced scores ranging from 0.26 for prey weight to 0.40 for prey occurrence, indicating low fish prey diet overlap. These data indicate that smallmouth bass are utilizing new forage resulting from restoration activities, but growth rates have not changed significantly. Smallmouth bass may not be forage-limited in the study area.
