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 …
