| Abstract: | In 2005, a population of invasive northern pike was discovered in Scout Lake near Sterling, Alaska, causing the Alaska Department of Fish and Game (ADF&G) to stop stocking fish in this lake. ADF&G treated Scout Lake with liquid and powdered rotenone formulations in October 2009 to eradicate the northern pike population. Gillnet sampling in spring 2010 after treatment indicated the northern pike population had been eradicated. Water quality sampling in Scout Lake indicated similar water quality characteristics before and after treatment. Comparisons of zooplankton and macroinvertebrate presence between summer 2009 (before treatment) and 2010 (after treatment) indicated that species diversity remained similar, although some zooplankton species were far less common in posttreatment samples. In August 2010, ADF&G restocked Scout Lake with rainbow trout and Arctic grayling fingerlings. |
