Within the Fishspot area there are several rivers and waters committed to fly-fishing only. Common for these areas is that it is only allowed to fish with flies with the fly-line as casting weight. These areas also have strict rules regarding the number of fish you can take out of the water (bag-limit), maximum size, and barb-less hooks. This means that trout, char or grayling over a certain size, for example 40 cm, must be released. I addition there might be limitation on the numbers of fishermen in the river.
