Puruveden muikku is the vendace of the species Coregonus albula caught in the clear waters of the Puruvesi lake basin situated in the north-eastern part of Lake Saimaa using seine nets, fyke nets, and net fishing.
Pruvesi has been known as a fishing area since the 14th century and the art of locating and catching the fish has been handed down from one generation to another. Puruveden muikku has a distinctive silvery color due to the exceptional clarity of Puruvesi waters.
