| Description | In Loomis Lake (Pacific County), the invasive non-native aquatic plants Eurasian watermilfoil and egeria were treated with the herbicide fluridone in 2002. We monitored aquatic plants and fish before herbicide application and for up to three years after treatment. The herbicide treatment resulted in a significant reduction of invasive plants for three years. The native submersed plant community was also significantly reduced, a result from fluridone use at nonselective rates and poor light penetration caused by sediment entrainment. After treatment, the growth of largemouth bass and pumpkinseed sunfish increased, small yellow perch abundance decreased, and larger pumpkinseed sunfish increased. This is an article in the Journal of Aquatic Plant Management, 47:2009, pp. 31-40. |
