The Carp-Dependent Ecosystem Urgent Management (Carp-DEUM) is a pilot project in a section of the UC Davis Arboretum Waterway that demonstrates a viable solution for improving water quality and preventing harmful algal blooms (HABs) in the Waterway via carp exclusion. Common carp and their close relatives engineer ecosystems through bioturbation of the benthic substrates, continuously uprooting vegetation and introducing trapped phosphorus from sediment into the water. With the removal of carp, there is less phosphorus mixed into the water, aquatic vegetation will be able to establish itself, and algal blooms will be reduced. More information, including a YouTube video on the project's research, can be found in this blog post by the California WaterBlog.
