In January 2010 a perch with a weight of 3.75 kg (8 lb 4 oz) has been caught in the River Meuse, Netherlands.[3] Due to the low salinity levels of the Baltic Sea, especially around the Finnish archipelago and Bothnian Sea, many freshwater fish live and thrive there. Perch especially are in abundance and grow to a considerable size due to the diet of Baltic herring.
