The U.S. Geological Survey (USGS) is seeking proposals for the provision of floating barges equipped with fin antennas as part of a Request for Quotations (RFQ) aimed at enhancing salmonid passage monitoring through the detection of 134.2 kHz PIT tags. The procurement requires vendors to deliver, install, and assemble the detection arrays at specified dam locations in Oregon, ensuring the systems can operate in various water depths and are remotely maintainable. This initiative is critical for monitoring fish passage and supporting ecological studies, with a total small business set-aside to encourage participation from qualified small enterprises. Proposals must be submitted electronically by June 23, 2025, with the performance period running from July 1 to September 16, 2025. For further inquiries, interested parties can contact Victor Nuno at vnuno@usgs.gov or by phone at 916-278-9442.
