| Notes | In aquatic environments, invasive colonial tunicates do particular damage, fouling and even smothering sedentary animals, competing with native animals for resources, and reducing biodiversity. In this Master’s thesis, the author examines two invasive tunicate species in Oregon and their effects on aquaculture, first at Winchester Bay from 2011 to 2016, and then in simulation. She points out that “ecological impacts are highly variable and region-specific,” and did not find excessive growth, and thus, no extensive damage done to aquaculture in this situation. |
