Salmon fluke .
This is a very small worm parasite (<1mm) which attaches to the outer body and gills of fish in the salmon family. It damages the skin and this can lead to infections. Unless heavily infested, it is unlikely that its presence will be noticed. There are many related Gyrodactylus species that are difficult to distinguish. This genus contains specialist and generalist parasites.
