The U.S. Fish and Wildlife Service, part of the Department of the Interior, intends to negotiate a sole source contract for the acquisition of InnovaSea Acoustic Telemetry System equipment, specifically acoustic transmitters for tracking adult Chinook Salmon. These transmitters are crucial for studying habitat usage, migration timing, and spawning locations, and must be compatible with existing Vemco receiver equipment to ensure data comparability and minimize costs associated with replacing the current receiver array. The procurement is justified due to the proprietary nature of the Vemco system, which has no alternative manufacturers or compatible products available. Interested parties must submit responses demonstrating the advantages of competition by April 29, 2025, to Contract Specialist Jack Skogen at Jack_Skogen@fws.gov.
