Fish And Macroinvertebrate Response To Restoration And Conservation Efforts, Madison C. Cogar Dec 2020

Fish And Macroinvertebrate Response To Restoration And Conservation Efforts, Madison C. Cogar

MSU Graduate Theses

Fish and macroinvertebrate response to restoration and conservation efforts varies in regards to the size and structure of the system (e.g. headwater streams in WV versus large rivers such as the Mississippi River). This project reviews fish and macroinvertebrate rebound in treated acid mine drainage (AMD) streams in WV as well as macroinvertebrate drift patterns in the Mississippi and Missouri Rivers. AMD is a product of a chemical reaction resulting in an acidic water outflow from mining sites, which may harm aquatic life. As a response, passive AMD treatment systems have been installed. I tested the effectiveness of remediation by …


Population Structure And Habitat Use Of Bluegill In The Upper Mississippi River, Ethan Allyn Rutledge Aug 2020

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 …
