Waterfowl harvest, Hunter Success, Wildlife Harvest Survey
A waterfowl bag check program was initiated in 1975 to estimate duck harvest, hunting pressure, hunter success and species composition of the harvest on 24 waterfowl areas. Sample design was such that it was easily repeatable and would permit detection of changes in harvest parameters. Analysis of management practices in light of these changes would then be possible. Estimated harvest for the 24 areas was 32,591 birds while estimated hunter trips totaled 46,131. Big Marsh, Eagle Lake, Otter Creek Marsh, Hawkeye Wildlife Area, Rush Lake (Palo Alto County), Riverton Wildlife Area, Green Island, New Albin Access, and Sweet Marsh accounted for 84.8% of the harvest and 81.4% of hunter trips. Harvest and hunting pressure was highest on weekends with the greatest intensity occurring on season openings. Species composition of checks showed the mallard (Anas platyrhynchos) was number one in the bag (28.6%) followed by blue-winged teal (Anas discors, 22.7%), green-winged teal (Anas carolinensis, 21.2%) and wood ducks (Aix sponsa, 14.1 %). The importance of each species in the bag varied greatly between areas.
