2	Pyrethroid Insecticide Effects on Bluegill Sunfish (Lepomis Macrochirus) and the Impacts of Bluegill Predation on Invertebrates in Microcosms Morris, Rodney Gregg 05 1900 (has links) Concurrent outdoor aquatic 1950 L microcosm and 0.04 ha mesocosm experiments with bluegill sunfish evaluated the ecological impact of cyfluthrin. Cyfluthrin effects were not observed on mesocosm bluegill; a slight decrease in growth was observed in the microcosm bluegill. Otolith weight to length relationships between bluegill size-classes from microcosms, local streams, and a fish hatchery revealed no differences. Our results indicated bluegill predation impacts were slight on benthic invertebrates. Extensive predation on emerging insects was observed. Microcosm bluegill impacts on zooplankton populations followed expected predation effects, resulting in larger populations of smaller taxa. Bluegill functioned as "keystone" predators for microcosm taxa and improved taxa richness for benthic colonizing invertebrates and zooplankton. bluegill sunfish cyfluthrin ecology pesticide effects Bluegill -- Effect of insecticides on Bluegill -- Behavior Pyrethroids
