Physical Effects of Increased Commercial Navigation Traffic on Freshwater Mussels in the Upper Mississippi River: Phase 1 Studies
Abstract
The purpose of this program is to monitor community composition and population structure at mussel beds in the Upper Mississippi River where L. higginsi is known to occur. In 1989, a decision was made to also conduct studies in pool 24 where L. higginsi has not been found. Results of these studies will be used to determine if and to what extent commercial navigation traffic in the UMR affects L. higginsi and other species of mussels. The purpose of the baseline studies discussed in this report was to obtain qualitative and quantitative data and select mussel beds for detailed study. In addition, this information will be part of the larger data set that will be used to evaluate commercial traffic effects. Keywords: Commercial navigation traffic; Biology; Mollusca; Freshwater mussels; Inland waterways.
