Grumlan's Fvo allows the public to buy fishing licenses for fishing with angling, drag, casting rod and during winter pimp fishing and angler fishing (max. 10 anglers).
During the first 14 days of crayfish fishing, fishing is prohibited between 19.00 and 06.00. The crayfish fishery starts in 2024 on August 7, which means that the fishing ban applies until August 20.
From 1 January 2024, a number of new fishing rules apply, see below:

Window outlet for zander and pike. For zander, a minimum size of 50 cm and a maximum size of 70 cm applies. For pike, a minimum size of 50 cm and a maximum size of 90 cm applies.

Catch limit per fishing license buyer and day: Maximum 3 walleyes and 3 pike per day.
Recommendation to avoid zander fishing from 1/4 to 31/5 to protect the zander during spawning.
