We use our electrofishing boat Elritsan for environmental monitoring of fish in larger watercourses and in lakes where net fishing and traditional electrofishing are not feasible. With this method, we broaden our possibilities for researching fish and fishing, while at the same time examine fish in a gentle way. The Elritsan boat is stationed at the Institute of Freshwater Research in Drottningholm.

Electrofishing can be used as a gentle method for environmental monitoring. An electric current attracts and stuns the fish, the fish is then caught with a net and is released after examination. When electrofishing, you must have the necessary training and ethics permit.
