Land Use Effects On Fish Assemblages In Mississippi River Tributaries In Scott County, Ia And Rock Island County, Il, Benjamin Ford, Kevin Geedey
Land Use Effects On Fish Assemblages In Mississippi River Tributaries In Scott County, Ia And Rock Island County, Il, Benjamin Ford, Kevin Geedey
Urban Watershed Project
Fish assemblages are viable indicators of stream quality because they respond predictably to changes in abiotic and biotic factors, such as habitat and water quality, and human exploitation and species additions. In this a study we examined the relationship between fish abundance, diversity, and IBI (Index of Biotic Integrity), and urban and agricultural land use in Scott County, IA and Rock Island County, IL. Fish were sampled during the summer of 2021 within 12 local watersheds, which contain a variety of land use types. We followed a standardized sampling method of a single pass with a backpack electrofishing unit through …

MSU Graduate Theses
Channel Catfish Ictalurus punctatus populations have been evaluated using many sampling gears in rivers. However, a consensus has not been reached on which gear or gears produce the most reliable population demographics. Specifically, this study compares population demographics of Channel Catfish throughout the Monongahela River, WV using multiple gear types. Fish were sampled seasonally during 2018 using baited hoop nets, low- frequency electrofishing, and trotlines. Firstly, too few fish were collected using electrofishing and were excluded from all analyses. In terms of relative abundance, fish sampled with hoop nets had higher catch rates (mean SCPUE = 5.8, SE = 0.4) …
