Three-spined stickleback (Gasterosteus aculeatus)
Several Gyrodactylus species have been recorded earlier from the G. aculeatus. A survey* of reports and papers revieled that so far G. arcuatus and G. branchicus were reported from the three-spined stickleback from Norway.
Several fish specimens collected 1977 in the Oslofjord area were screened, and as expected many gyrodactylids were found. They were mounted for microscopic inspection. The majority of parasites was identified as Gyrodactylus arcuatus. There may be also some other Gyrodactylus species as well, but proper identification of the mounted parasites is pending.
