SLU Aqua's electric fishing boat Elritsan is used for environmental monitoring of fish in larger watercourses and in lakes where net fishing and traditional electric fishing are not feasible. With this test fishing method, we broaden our opportunities to research fish and fishing, while we can examine fish in a gentle way. Elritsan is stationed at the Institute of Freshwater Research in Stockholm.
Electrofishing is widely used to assess fish assemblages. Electro fishing from a boat is a gentle test fishing method. Electric current attracts and stuns the fish that are caught with nets. After species identification, measurement and a moment of recovery, the fish are released back into the water.
Our electrofishing boat Elritsan (transl. The Minnow) is stationed at the Institute of Freshwater Research in Stockholm. Inquiries about the boat are made to Helena Strömberg or Magnus Dahlberg.
