Winter Fish Populations in Probable Locations of Air Bubblers in the St. Marys River-Lake Superior Area
Abstract
A series of field studies were conducted by NUS Corporation in five areas where air bubbler sites were proposed for the St. Marys River and Whitefish Bay to keep channels ice free for winter vessel passage. The studies were done to determine base line ecological conditions and the effects of the bubblers on respective fish and benthic communities.
