White Grub In Bluegill In The Sangamon River: Impact Of Sewage Effluent And Flow Regime On Infection Parameters, Miranda White
White Grub In Bluegill In The Sangamon River: Impact Of Sewage Effluent And Flow Regime On Infection Parameters, Miranda White
Masters Theses
White grub (Posthodiplostomum minimum) is a digenetic trematode that uses a piscivorous bird, a pulmonate snail, and a centrarchid fish to complete its life cycle. To assess the impact of impoundment and sewage effluent on white grub infection parameters, infections in bluegill (Lepomis macrochirus) were monitored in 3 reaches of the Sangamon River near Decatur, Illinois: Reach 1- free-flowing river upstream of Lake Decatur Dam, unimpacted by sewage effluent, Reach 2- impounded flow below Lake Decatur Dam, unimpacted by sewage effluent, and Reach 3- free-flowing river downstream of Sanitary District of Decatur, impacted by sewage effluent. Liver and kidney abundances …
An Assessment Of Night Time And Seasonal Electrofishing In The Lower Wabash River, Eric Christopher Hine
An Assessment Of Night Time And Seasonal Electrofishing In The Lower Wabash River, Eric Christopher Hine
Masters Theses
Large rivers are highly important systems; being exploited both commercially and recreationally. Because of this usage by humans, close monitoring of the ecology of theses rivers is of the utmost importance. The Long-Term Electrofishing project (LTEF) monitors the fish communities of the Illinois, Mississippi, Wabash, and Ohio rivers using day time, pulsed-DC electrofishing during the late Spring through the early Fall each year. Given that previous studies have noted diel and seasonal changes in catch and composition of fish communities, the addition of night time electrofishing may be beneficial to the overarching goals of the LTEF. This study sought to …
