The purpose of this study was to assess the fishery improvement opportunities on the Box Canyon portion of the Pend Oreille River. This three year study was initiated as part of the Northwest Power Planning Council's 1987 Columbia River Basin Fish and Wildlife Program. This report contains the findings of the second year of the study. Currently, yellow perch (Perca flavescens (Mitchill)) are the predominant fish species in the river and largemouth bass (Micropterus salmoides (Lacepede)) are the predominant sport fish. The objectives of the second year of the study were to determine: the relative abundance of each species in the river and sloughs; the population levels in five selected tributaries and, if possible, for fish in the river and sloughs; fish growth rates; the feeding habits and abundance of preferred prey; migration patterns; and the total fishing pressure, catch-per-unit-effort, and total harvest by conducting a year-round creel survey. 55 refs., 7 figs., 154 tabs.
