Alternate Control Strategy for Dreissinids Using Carbon Dioxide

Project ID: 21066
Principal Investigator: Kevin Kelly
Research Topic: Invasive Species
Funded Fiscal Years: 2021 and 2022
Keywords: None

Research Question

Zebra and quagga mussels (Dreissena ssp.) are major macrofouling species that impact the operations and maintenance of Reclamation water delivery systems. There is a need for economical and environmentally safe control strategies for these invasive mussels within Reclamation structures.
This project proposes to investigate the effectiveness and applicability of carbon dioxide under field conditions found in Reclamation facilities. This project also proposes to develop and test the most efficient process for the carbonation of infested flowing raw reservoir water that will prevent veliger settlement and colonization within Reclamation structures.

Need and Benefit

There is a need for environmentally-friendly and economical mitigation of invasive mussel settlement and colonization in Reclamation structures. This proposal could also fit into other research need categories, such as control in closed systems (pipes). The results of this project may also lead to prevention where new construction design or modification can be made to incorporate carbon dioxide for long-term control of mussel infestation.
