Population Structure And Habitat Use Of Bluegill In The Upper Mississippi River, Ethan Allyn Rutledge
Population Structure And Habitat Use Of Bluegill In The Upper Mississippi River, Ethan Allyn Rutledge
MSU Graduate Theses
Fish populations are driven by the dynamic rate functions (i.e., recruitment, growth, and mortality). Knowledge of these vital rates can provide critical information to determine spatiotemporal population-level changes in the system. Therefore, understanding these vital rates are important in the proper management of any fishery. Anthropogenic modifications to the environment have had damaging effects on the organisms within these ecosystems. Specific to Upper Mississippi River fishes, channelization, dams, and loss of floodplain connectivity have all been purported as deleterious. In the face of these modifications, understanding habitat use and vital rates of individual species is needed to help guide management …

Gear Specific Catch Rates And Population Dynamics Of Channel Catfish In The Mississippi River, Colby Gainer
MSU Graduate Theses
Perpetual anthropogenic alterations have imposed deleterious effects on aquatic ecosystems. In the Mississippi River, channelization, dams, and loss of floodplain connectivity have all been reputed as detrimental. Dynamic rate functions (i.e., recruitment, growth, and mortality) are the driving forces behind fish populations. Understanding population dynamics is important for guiding management decisions. Knowledge of vital rates can provide pivotal information that will determine spatiotemporal population-level changes within the system. In the Mississippi River, Channel Catfish are a commercially and recreationally important species. However, limited population demographic information currently exists in the Upper Mississippi River. We sought to determine the most effective …
Growth And Population Assessment Of Spotted Bass (Micropterus Punctulatus) In Beaver, Table Rock, And Bull Shoals Lakes, Northern Arkansas-Southern Missouri, Jeremy Troy Risley
Growth And Population Assessment Of Spotted Bass (Micropterus Punctulatus) In Beaver, Table Rock, And Bull Shoals Lakes, Northern Arkansas-Southern Missouri, Jeremy Troy Risley
MSU Graduate Theses
Little research has been conducted on spotted bass, Micropterus punctulatus, even though it is a popular recreational fish. Most previous research was on young-of-the-year fish and interactions among other species in reservoirs, with little research on adult spotted base in the Ozarks region or other regions of the United States. The objective of this study was to compare the growth and population characteristics of spotted bass within and among Beaver, Bull Shoals and Table Rock Lacks. Growth, abundance, and conditions within and among reservoirs were similar. However, spotted bass in Beaver Lake did not reach as great lengths as those …
