Assessing The Short-Term Effects Of Translocation On Freshwater Mussels: Is Habitat Or Water Quality More Important?, Joshua D. Arnold
Assessing The Short-Term Effects Of Translocation On Freshwater Mussels: Is Habitat Or Water Quality More Important?, Joshua D. Arnold
Masters Theses
Freshwater mussels (Order: Unionida) are very important to the function of aquatic ecosystems and are typically indicators of good water quality. They provide a valuable link between the water column and the benthic substrate in which they live and are a valuable food resource for many species of animals. However, most species native to North America are currently threatened with extinction, to the point that more than 70% of native freshwater mussels are listed as either threatened or endangered at the state or federal level. The cause of this decline can be attributed to historical over exploitation, habitat alteration, and …
Evaluation Of Lake Sturgeon (Acipenser Fulvescens) Spawning Success On An Artificial Reef Constructed In The Kalamazoo River, Michigan, Jason P. Lorenz
Evaluation Of Lake Sturgeon (Acipenser Fulvescens) Spawning Success On An Artificial Reef Constructed In The Kalamazoo River, Michigan, Jason P. Lorenz
Masters Theses
Since lake sturgeon Acipenser fulvescens monitoring began on the Kalamazoo River in 2009, there has been no documentation of survival past the egg stage. Spawning has occurred directly below Calkins Dam and, in 2016, an artificial spawning reef was constructed 275-m downstream to improve habitat and increase survival to the larval stage. The site was monitored with egg mats and larval drift nets to document evidence of successful natural reproduction of lake sturgeon one year prior to construction (2016) and three years post-construction of the artificial reef (2017-2019). Fertilized lake sturgeon eggs were captured all four years of the study …

Diel Fish Habitat Selection In A Tributary Stream, Andria K. Salas, Eric B. Snyder

This study investigated the location and diel habitat preferences (at 100 m reach scale) of fish in a small tributary stream in late spring, early summer. During the day, coho (Oncorhynchus kisutch) preferred areas with more cover (deeper, greater extent of undercut banks) vs. night when LWD was preferred (Pearson correlation and step-wise MLR). Chinook (O. tshawytscha) exhibited an opposite pattern, preferring LWD during the day vs. higher velocity at night. This suggests these two potadromous species may be partitioning resources. Pooling coho, chinook and rainbow trout (O. mykiss) indicated reaches with more LWD …
Fish Assemblages In Manistee River Tributaries: Longitudinal Distribution Analysis, Seasonal Variation, And Riparian Improvement Evaluation, Nicholas J. Gressick
Fish Assemblages In Manistee River Tributaries: Longitudinal Distribution Analysis, Seasonal Variation, And Riparian Improvement Evaluation, Nicholas J. Gressick
Masters Theses
Sedimentation affects both stream physical and biological integrity. Improperly designed stream passage accompanied with sedimentation and altered hydrology can impede fish passage and reduce fish assemblage integrity. The purpose of this study was to: 1) quantify impacts of poorly constructed road stream crossings and eroding banks on fish assemblages, and 2) assess these sites as sediment sources and connectivity breaks on entire fish assemblages and individual fish species. Electrofishing was conducted during spring and fall 2004 and 2005. A total of 29 electrofishing reaches were sampled which included 5 road-stream and streambank restoration sites. Sickle Creek (1st order) had reduced …
