Lake Mjøsa

Mjøsa has rich fish stocks; there are 20 species in total. The most famous and most coveted by anglers is the large Mjøsa trout, which can grow as big as 15 kilos. In early summer, trolling for big trout is popular. Mjøsa also offers good catches of pike, perch, burbot, grayling and trout. The trout spawn in many of Mjøsa's tributaries and grow big in the lake.
  
Even though giant catches are few and far between, there is a good chance of hooking a trout over ten kilos. Mjøsa's most impressive feature is its rich stocks of top quality fish. So the lake is natural venue for a trolling battle between anglers. The Norwegian trolling championship takes place in June, starting from Gjøvik harbour.
