The Bureau of Reclamation, under the Department of the Interior, is seeking qualified contractors for the monitoring of the endangered Razorback Sucker fish in Lake Mohave, Arizona-Nevada. The project involves a comprehensive monitoring program that includes capturing and recording data on both adult and larval Razorback Suckers, conducting genetic analyses, and participating in multi-agency survey events, with a contract duration consisting of a base year and four one-year options. This initiative is crucial for the conservation of the Razorback Sucker, which has historically been abundant in the Colorado River Basin but is now endangered under the Endangered Species Act. Interested parties must submit their capability statements by 2:00 PM local time on October 10, 2024, to Kathleen Berry at kberry@usbr.gov, and should be aware that registration in the System for Award Management (SAM) is required for eligibility in future solicitations.
