Development of a life history database for Upper Mississippi River fishes. U.S. Geological Survey, Upper Midwest Environmental Sciences Center, La Crosse, Wisconsin. LTRMP 2007-T001. 10 pp. + Appendixes A–B. Abstract: This report summarizes the development of a life history database for Upper Mississippi River System fishes. It provides the rationale for its development within the Long Term Resource Monitoring Program, describes it, outlines standards for its development, and demonstrates how it can be linked to the LTRMP fisheries database and used to address a host of new questions relevant to management and science in the basin.
