Gill nets are among the most effective gear for collecting many species of lake fishes. In scientific investigations we usually use gill nets with several sizes of mesh to sample fish of various sizes. The standard experimental gill net usually consists of 25-foot lengths of the following stretch measure mesh sizes: 1.5, 2, 2.5, 3, and 4 inches. These nets will catch, with little size selection, walleyes and suckers from 6 to 23 inches, and yellow perch, yellow bass, white 'bass, and bullheads from 4.5 inches to their maximum sizes.
