Anchor worm (Lernaea sp.) is an example of introduced parasites which accompany exotic fish species. In Egypt, Larnaea was not known before the introduction of the broodstock of common carp (Cyprinus carpio). Afterwards, Chines carps (silver carp, bighead carp and grass carp) good also infected. Hatcheries which keep carp broodstock usually carry out the appropriate treatment against lernaea.
