state speargun record for the invasive round goby was taken by out of Door County waters on the Lake Michigan side. It weighed 5.0 ounces and was 8.25 inches long. Tagging studies have shown whitefish migrating from Big Bay de Noc which has less food to the plentiful waters off the peninsula. On five occasions from May through June 2017, researchers attempted to catch larval fish at the mouth of Sugar Creek using traps with green glowsticks as lures. They only caught white suckers, with the traps catching the most suckers per hour from May 15–22. Smallmouth bass in county waters off the Green Bay side have been found to migrate more than those off the Lake Michigan side or near Washington Island. In 2021, an outbreak of Largemouth Bass Virus among smallmouth bass occurred in county waters on the Green Bay side. From 2007–2010, two smallmouth bass within Sturgeon Bay were found to be infected with viral hemorrhagic septicemia. Each of the two bass were infected with a different variant. Both variants have only been found in the upper, but not middle or lower Great Lakes. Fishing Remains of sturgeon, catfish, sucker, smallmouth bass, white bass, walleye, and drum left behind by Native Americans were found near North Bay in the 1960s. In 1965, strong restrictions from the Wisconsin DNR forced some commercial fishermen to change careers. Prior to that, fish were flown out to Midwestern metro areas the same day they were caught. Today, lake whitefish and yellow perch are caught commercially, and lake whitefish are also caught commercially by ice fishing. In 2019, anglers spent an estimated 181,342 hours fishing off the eastern shore of Door County, 222,088 hours fishing off the eastern shore of Kewaunee County, and 1,113,129 hours fishing in the entirety of Green Bay. The figures document a decrease from 1990, when anglers spent an estimated 406,998 hours fishing off the eastern shore of Door County, 279,385 hours fishing off the eastern shore of Kewaunee County, and 1,245,291 hours fishing in the entirety of Green Bay. Surfing Lake Michigan shoreline is used for lake surfing. One guidebook names the shore off Cave Point County Park as the best surfing area. Another water sport is windsurfing. Climate Rare snails From 1996 to 2001, researchers identified 69 species of snails in Door County, the most out of the 22 counties in the study. Most of these
