Protected areas

Fish that swim from creeks and into the sea – or vice versa – must be able to do so freely. This is one of the reasons why some zones are stated as “protected areas” where it is not allowed to fish. The protected areas are the places where creeks and brooks run into the sea and the fjord.

There are a couple of protected areas in Mariager Fjord. Some of the areas are protected from fishing during the entire year, while some are just protected from 16th September to 15th March. It is very important to respect these rules, since its purpose is to protect the fishing stock.

The unwritten rules

Besides the formal rules, a number of unwritten rules for anglers, as always should be obeyed:


  1. Show respect to nature. You who are a guest, so respect the fauna, crops and wildlife.
  2. Always clean up after yourself.
  3. Show consideration when parking. Use the possible parking spaces, and do not block small roads.
  4. Keep your distance from other anglers, which particularly applies when wade fishing for trout.
  5. It is good manners not to fish with more than a maximum of two rods per. angler at a time.
  6. If you encounter large schools of small trout or smolt, choose another fishing spot. If you continue to fish, there is great risk that many of them die after latches and discards. Large schools of small trout and smolt occur particularly in spring, and often it is enough to move a few hundred meters.
  7. If you experience a fantastic day of fishing - and you catch many fish over the goal - then also discard fish over the target, or stop when you’ve caught plenty for the freezer.
