Abstract

Creel censuses were conducted on the Des Moines River during the open water seasons, usually April through November, from 1953 through 1961. The data indicated a relatively constant catch of fish. The rate of annual catch varied between a minimum of 0.26 and a maximum of 0.61 fish per fisherman-hour. The data were also analyzed by "proficiency categories" involving (1) all fishermen, (2) fishermen with one fish, (3) fishermen with two fish, and (4) fishermen with three or more fish. The most proficient fishermen (those with three or more fish at the time of interview) constituted l3 per cent of all anglers, and caught 65 per cent of all fish. The average length of the angler day for the census period was 2.3 hours. Channel catfish, carp, bullheads, and walleye pike, in that order, were the important fish taken. Fisherman aptitude or skill is concluded to be the significant factor related to both the catch of fish and the rate at which they are caught.
