Reliability of standard experimental gill nets for estimating comparative size of perch, pikeperch, and pike populations is considered in the light of 31 series of gill‐net catches from Minnesota lakes. Factors influencing the catch of gill nets are discussed. Because of the wide range of errors associated with means of series of gill‐net catches, comparison of catch means at a probability level greater than 80 percent appears to be not practically feasible. A table showing error of means of series of net catches at this probability level is included.
