Description
Summary:Though potential direct effects of extended season commercial shipping are of special concern in narrow channel areas of the St. Marys River, back-water connected bays such as Munuscong Bay support a high diversity of fisheries resources and an environmental baseline study would be incomplete without some quantification of limnological and fisheries aspects associated with these habitats. Previous studies have documented environmental conditions from channel to shoreline at seven major sites along approximately 64 km (40 mi) of the St. Marys River. The present study, although more limited in scope, employed comparable techniques in studying physical and chemical aspects, aquatic invertebrates, and fishes (larvae, juveniles and adults) within Munuscong Bay, one of the most important sport fishing areas with the St. Marys River system.
