**NAICS:** 541715

The U.S. Geological Survey (USGS), within the Department of the Interior, seeks a Great Rivers Cooperative Ecosystem Studies Unit (CESU) partner to develop and test passive samplers for invasive carp eggs and larvae.
- **Government buyer and opportunity**
  - Buyer: U.S. Geological Survey (USGS), Department of the Interior; no sub-agency or office is specified.
  - One cooperative agreement is expected for an eligible Great Rivers CESU partner.
- **Research requested**
  - Develop, fabricate, and test hydrodynamically based, debris- and detritus-shedding passive samplers to capture downstream-drifting eggs and larvae of bighead, silver, grass, and black carp.
  - Conduct laboratory flume testing, first with preserved eggs and then with live eggs and larvae; field-test successful designs alongside traditional sampling and compare detection probability.
  - Publish research results and data, support technology transfer, and pursue patents for novel designs when appropriate.
- **Funding and performance**
  - Estimated total funding is $300,000, including approximately $34,000 for the first budget year; later funding depends on progress and availability.
  - No cost sharing is required. The project has one base year and up to three renewal years.
- **Notable requirements**
  - The agreement anticipates substantial USGS involvement and collaboration.
  - No OEMs or commercial vendors are identified. No manufactured products or part numbers are requested.

### Description

The U.S. Geological Survey is offering a cooperative agreement to a participating Great Rivers Cooperative Ecosystem Studies Unit partner to develop and test hydrodynamically based passive ichthyoplankton samplers. The samplers are intended to capture downstream-drifting invasive carp eggs and larvae in rivers, supporting early detection of invasive carp and their reproduction. The announcement anticipates one award, with total estimated program funding of $300,000 and an award range of $1 to $300,000. Cost sharing is not required.
