The Gran Canaria boat fishing license is valid on all of the Canaries, and is ideal for those who want to do trolling. If you don't want to do trolling, then the regular shore fishing license will do, even if you're fishing from a boat. In the video below, you can see one of the locals get ready to go fishing with his kayak.
Below is the order form for the "fishing from a boat" license, with trolling. The cost of this type of license is 60 euros, but you can save a few euros, if you order more than one license. Processing time is a couple of weeks.
Please note that the fishing office will shut for holidays until December 10th, 2020. All licence orders will be processed after that date.
