The U.S. Fish and Wildlife Service (FWS) intends to award a sole source contract to Biomark, LLC for the procurement of a new updated Vaki Micro Single Channel computer and a Vaki Split Head camera system. This acquisition is critical for retrofitting an outdated fish counter, enhancing data collection efficiency and accuracy for juvenile fish analysis, as Biomark is the only vendor in the U.S. supplying the necessary parts. The sole source justification is based on urgency and the absence of alternative suppliers, with the contracting officer certifying that the costs from Biomark are fair and reasonable. Interested parties may submit capability statements via email to carter_duke@fws.gov, as no telephone requests will be honored.
