Large carp populations kept Fish Camp crews constantly at work as the camp supervisor arranged sales to local businesses and commercial markets and the foreman and crewmembers seined fish in Dane County lakes, especially Kegonsa and Waubesa. Catches peaked in spring and fall when carp schooled, and although carp made up the biggest haul, crews also caught other rough fish, including freshwater drum, white sucker, bigmouth buffalo, long-nosed gar, and bowfin. After a skilled veteran located a large school, barges carried long seine nets into the lake to surround the fish, motor-driven winches tightened the net into smaller circles, and the crew pulled the seine bag toward shore and dumped the catch into a crib for sorting. In the crib, game fish such as walleye, bass, and pike were hand-netted and returned to the lake, while bigmouth buffalo, valued for superior taste, were sold separately for 25 to 50 cents per pound in the 1950s, compared with less than 10 cents for carp. The harvest operation continued after the catch as fish were kept alive in pens or a holding pond at the mouth of the Yahara River, boxed, trucked to railroad stations in Madison and Janesville, and shipped in specially fitted boxcars to distant markets such as New York and St. Louis. Beginning in 1899, Wisconsin tried to remove carp from waters where it had introduced them in the previous decade, first by licensing individuals, then by contracting with commercial fishers, then from 1935 to 1969 by operating nine fish camps on lakes and rivers where carp were numerous, with typical annual harvests exceeding five million pounds, while a state cannery built in Madison in 1936 later processed carp for hatcheries before moving to Wisconsin Dells.
