OVERVIEW, RECIPIENT AND NPS SUBSTANTIAL INVOLVEMENT OVERVIEW: This project will determine the invasion extent, reproduction-emigration status and control tactics pertaining to Asian swamp eel in the Chattahoochee River through the application of both traditional and molecular fisheries research techniques. This project will provide Chattahoochee River National Recreation Area resource managers with high-quality scientific research and technical assistance related to the problem of the Asian swamp eel. STATEMENT OF JOINT OBJECTIVES/PROJECT MANAGEMENT PLAN: Conduct scholarly research; execute scientific design and methodology in order to determine extent of Asian swamp eel invasion and assess reproduction-emigration potential of the Asian swamp eel in the Chattahoochee River and neighboring areas. RECIPIENT INVOLVEMENT: Oklahoma State University will conduct the project, oversee project management, provide backpack electrofisher equipment, conduct all laboratory activities, and manage project data. NATIONAL PARK SERVICE INVOLVEMENT: NPS Biologists with CRNRA will assist with project goal development, field sampling for Asian swamp eels, providing access to sampling sites, and assist in collection and review of project data. NPS will also contribute equipment and lab space and implement safety standards applicable for the safety of field-going personnel working on the study (both NPS and recipient personnel). Oklahoma State University is a member of the Great Plains Cooperative Ecosystems Studies Unit who was awarded a Master Cooperative Agreement (H60001100100) allowing Oklahoma State University to participate in specific tasks, and can provide the necessary activities involved in this particular task while providing an effective outcome for NPS and the objectives of this research/educational project. The Principle Investigator chosen is uniquely qualified to execute this project. He is an expert on fish ecology of the Chattahoochee River, is one of the few published researchers on the Asian swamp eel in the Chattahoochee, and is intimately familiar with NPS trust resource management. He also has a developed, existing network of federal, state, and local colleagues which he will engage on this project. These partnerships will be essential for proper project completion.
