Charter boats offer sea fishing excursions from many Danish harbours at reasonable prices. And large groups can often charter the whole boat. Such trips are available all year round in, for example, Copenhagen, Helsingør, Korsør and Frederikshavn. From other harbours, trips are only available in summer.

Participants in such trips must possess a national rod licence. Otherwise, no special permits are required for sea fishing. Local tourist information offices can provide addresses, etc.

Danish fishery legislation stipulates minimum size limits and closed-seasons for certain species of fish and crayfish. Please note that fish and crayfish caught during their respective closed-seasons or which are under the statutory minimum size limit must be immediately released to the water again, preferably while still alive but even if dead. Keeping a closed-season or undersized fish can never be excused on the grounds that it was hooked so deeply that it would have died anyway.

The outlets of rivers, streams and inland waters are protected by no-fishing preservation zones. Fishing within 500 metres of where a river, stream or inland water runs into the sea or fjord is prohibited. There may also be local fishing regulations which must be observed at all times.
