One of the more effective and most frequently used methods of regulating harvest to improve a fishery is the use of a minimum length limit. To determine the effects of an 8-inch minimum length limit on smallmouth bass (Micropterus dolomieui) in Nebish Lake, Wisconsin, the sport fishery was studied for 5 years (1977-81) and contrasted to the previous 5-year period (1972-76) when there was no minimum length limit. The sport fishery included smallmouth bass and yellow perch (Perca flavescens). Population characteristics of smallmouth bass and yellow perch were compared for the 4-year periods of 1974-77 (pre-length limit) vs. 1978-81 (post-length limit), because the length limit imposed on 1 January 1977 would not have affected these parameters when measured in spring 1977.
