Development Of An Automated Detection System For Nitrite In Aquatic Environments, Tim Schierenbeck
Development Of An Automated Detection System For Nitrite In Aquatic Environments, Tim Schierenbeck
Theses and Dissertations
The main objective of the project is to develop an automated nitrite sensor for use in aquatic environments, and more specifically for use in recirculating aquaculture systems (RAS), where monitoring can help sustain a controlled environment, protect against nitrite intoxication, and promote fish health. Detecting nitrite manually with semi-quantitative colorimetric test kits, although inexpensive and simple, is prone to inter-user variability and poor sensitivity. An automated nitrite sensor has potential to provide higher resolution measurements at both concentration and time scales and can serve as a research tool for the study of filtration systems essential in maintaining a healthy RAS …
Assessment Of Benthic Habitat Quality In Lower Green Bay, Lake Michigan With Special Regard To Potential Hexagenia Recolonization, Christopher Michael Groff
Assessment Of Benthic Habitat Quality In Lower Green Bay, Lake Michigan With Special Regard To Potential Hexagenia Recolonization, Christopher Michael Groff
Theses and Dissertations
With environmental remediation in the Great Lakes, Hexagenia have recovered or are recovering in systems from which they were once extirpated. An active Hexagenia recovery does not appear to be taking place in lower Green Bay. This study first examines the highly fluidized nature of lower Green Bay sediment as a possible cause for their lack of recovery due to nymphs’ potential inability to construct and maintain burrows essential to the completion of their life cycles. Hexagenia bilineata nymphs collected from the Upper Mississippi River were distributed into oxygenated aquaria containing substrates from lower Green Bay or the Upper Mississippi …
