When perch, pike, and whitefish are plentiful, gill-nets are an effective and legal means of catching fish in northern Finland. Nets were set in a semi oligotrophic coldwater lake perpendicular to the shoreline up until 2 meters water depth. Usually deployed at 9 pm and checked the following morning at 8 am, the nets revealed nearly 20 kilos of fresh fish. Some will be salted and smoked with alder, the remaining frozen and consumed during the winter.
