Assessing Management Actions and Their Effects on the Population Dynamics of Tr

The US Geological Survey is conducting market research to identify qualified businesses capable of providing scientific and technical consulting services for a project titled "Assessing Management Actions and Their Effects on the Population Dynamics of Trout Species." This pre-solicitation notice seeks professional services to support statistical modeling and analysis of rainbow and brown trout populations in the Glen Canyon Dam area through fiscal years 2025-2027. The project requires expertise in mark-recapture sampling design, quarterly data collection coordination, and advanced statistical analysis to produce estimates of trout abundance, survival, growth, and body condition. Qualified contractors must demonstrate capability to conduct field coordination for quarterly monitoring events, complete data analysis within 60 days of each collection period, and support the development of peer-reviewed publications and scientific presentations. Capability statements must be submitted electronically to yangzhideng@usgs.gov by June 25, 2025, at 1500 PST, with the NAICS code 541690 (Other Scientific and Technical Consulting Services) and size standard of $19 million applying to this opportunity.

This opportunity does not include any set-aside designations and is open to all responsible sources meeting the qualification requirements. The statement of work indicates a multi-year engagement spanning fiscal years 2025-2027, with quarterly field collection activities scheduled for January, April, June, and November of each year. The project involves collaboration with Grand Canyon Monitoring and Research Center staff and the Arizona Game and Fish Department, requiring coordination of four field collection trips annually in the Glen Canyon Dam to Lees Ferry reach. While specific contract values are not disclosed in this sources sought notice, the work encompasses comprehensive population dynamics modeling, environmental impact analysis, and management action efficacy assessments. The contractor will be expected to develop predictive models examining how environmental factors such as dissolved oxygen, water temperature, and flow experiments influence trout population dynamics across multiple life stages.
