Qualitative Biological Survey of Aquatic Macrophytes and Larval, Juvenile and Adult Fish of the Upper St. Marys River.

摘要

This study was conducted in conjunction with the alternatives considered in the Great Lakes Connecting Channels and Harbors Study, to collect qualitative biological information in order to facilitate characterization of a 15-mile portion of the St. Marys River above the Sault Locks. This report presents the findings on aquatic macrophytes and larval, juvenile and adult fish of the study area. The results of this effort indicate that the habitats present in the upper St. Marys River have the capability to provide many varied life history requirements for many important fish and wildlife resources.
