Lumpfish (Cyclopterus lumpus)
For the lumpfish (Cyclopterus lumpus) the GyroDb database lists only one Gyrodactylus species, G. cyclopteri. To our knowledge the species has not been reported from Norwegian lumpsuckers yet.
We have checked four fish collected in 1903, 1912, and 1983, respectively, and found G. cyclopteri on three of them. The parasite occurs on fish from the Oslofjord as well as from Troms (Northern Norway).
