If the fishing association doesn't provide any special offer, there is no discount for elderly - but people over the age of 65 are not obligated to purchase the Mandatory Fishing license provided by the Danish government.
When fishing in Denmark, you must always posses a Mandatory Fishing license, regardless of where you are fishing if you are in the age between 18 and 65. The Mandatory Fishing license can be bought at http://fisketegn.dk
The Mandatory Fishing license does not give you permission to fish at the various fishing associations waters, but is mandatory for fishing in Denmark. You are however allowed to fish by the shore and at governmentally owned fishing sites without buying additional licenses.
You can pay with the following credit cards:
