These spreadsheets summarize a yield-per-recruit model of a trout population consisting of up to two stocked and two wild components. Input is stocking records, creel survey and population estimates. Can estimate the effects on a fishery of changes in size limit, stocking rate, size of stocked fish, fishing intensity, or natural survival of fish. The documentation is good, however, there are no menus to assist the user in navigating the spreadsheet.
