Zebra Mussel Research Technical Notes. Impacts of Zebra Mussel Infestations on

摘要

Dense populations of zebra mussels (Dreissena polymorpha) have the potential togreatly impact water quality. By removing particulates and associated nutrients and contaminants from the water column and redistributing them to the sediments, zebra mussels affect water clarity, nutrient and contaminant cycling, and sediment quality. The purpose of this technical note describes potential changes in water quality as a result of zebra mussel infestations in aquatic systems, based on a review of the literature. The preliminary results of field studies to assess nutrient cycling are also presented. Important reference sources for more detailed information are listed at the conclusion of this technical note. Results of laboratory investigations to describe impacts at the sediment-water interface are presented in Technical Note ZMR-1-33.
