Both quagga (Dreissena rostriformis bugensis) and zebra (Dreissena polymorpha) (QM/ZM) and harmful algal blooms (HABs) are topics of concern in the western United States. As QM/ZM continue to spread into new waterbodies, there is more opportunity for potential interactions between these invasive mussels and algae communities. Understanding how these two separate issues impact each other is important for researchers and water managers. This scooping proposal was a literature review to assess the research that has been performed. Appendix A contains a list of State and Federal web based HAB resources. Appendix B contains selected abstracts that show the connections between HABs and QM/ZM. Some of interactions involve QM/ZM feeding on algae, water quality impacts, and algal impacts on mussel fertility. Understanding the interactions between QM/ZM and algal blooms is important as both issues continue to increase.
