Data on walleye (Stizostedion v. vitreum) population dynamics and angling statistics from a northwestern Minnesota Lake are presented. Many Point Lake has an area of 1,716 acres, and in years studied (1955–1957) had an average annual fishing pressure of 17 man-hours per acre. The average annual harvest of fish of all species was 7.5 pounds per acre of which about 60 percent was walleyes and pike, (Esox lucius). To study relationships between the walleye population and catch, 3,249 adult walleye were marked with distinguishing fin clips during the three years, and these fish tallied in anglers' catches. By application of appropriate statistics it is concluded that, on the average, 26.8 percent of the adult walleye population was taken by anglers each year. Lots of adult fish from natural causes was found to be about 4 percent per year.
