Monitoring protocol for the nearshore ecosystem in the south basin of Lake Winnipeg / Mélanie Aminot, Amanda L. Caskenette, Eva C. Enders. : Fs97-6/3386E-PDF

"Since their introduction, Aquatic Invasive Species (AIS) have posed major threats to Canadian waterbodies, industries, and tourism. As AIS continue to invade and change Canada’s native ecosystems, provincial, territorial, and federal governments are acting through the implementation of new measures and laws in hopes of controlling the spread. However, the lack of public awareness and scientific knowledge of AIS is hindering these efforts, and therefore the management of their spread remains a key issue that needs to be addressed. Since 2013, Zebra Mussels (Dreissena polymorpha) have invaded Lake Winnipeg and are thought to affect the lake’s ecosystem. The purpose of this technical report is to present a standardized monitoring protocol of the nearshore ecosystem of the south basin of Lake Winnipeg in order to determine the effects of Zebra Mussels on the nearshore food web. This report provides detailed sampling methods for the collection of water, fishes, zooplankton, benthic invertebrates, mussels, and sediment, as well as monitoring guidelines for environmental variables such as water depth, wave frequency, light penetration, and water temperature. Data emerging from this field work will benefit the monitoring and the control of AIS as well as provide insight on the population status of native species in Lake Winnipeg"--Abstract, page vii.
