The Engineer Research and Development Center (ERDC) is offering a cooperative agreement for the National Information Collaboration on Ecohydraulics (NICE) project, focusing on the acoustic tracking of fish near navigation infrastructure. The objective is to develop innovative techniques for obtaining high-resolution fish position data in challenging hydraulic environments, particularly around locks and dams in the Mississippi River and its tributaries. This research is crucial for understanding fish movement and improving fish passage management while maintaining navigation operations, especially given the increasing concern for native fish species and their habitats. The total funding available for this opportunity is $450,000, with a proposal submission deadline of January 18, 2024, and interested applicants should contact Phoebe V. Fuller at phoebe.v.fuller@usace.army.mil for further information.
