Ectoparasitic Diseases in Freshwater Ornamental Fish and Their Treatments


Koyuncu, C.Erkin

Fish parasites and their effects have become increasingly visible during the latest decades inconnection with the development of fresh water ornamental Fish industries troughout the world. Diseases problem including hazards caused by parasitic organisms are the main threat to further increase of the industry. Ectoparasites are the most common and widely distributed of freshwater ornamental Fish. Such as, protozoan ectoparasites of aquarium fish (Ichthyophthirius multifiliis, Ichthyobodo necatrix, Chilodonella cyprini, Oodinium limneticum, Trichodinids); external worms of fish (Dactylogyrus extensus, Gyrodactylus bullutarudis); external crustaceans (parasitic copepods, Argulus japonicus, Argulus foliaceus, Lernaea cyprinacea).The fish louse Argulus spp. is now the main problem in cage-cultured freshwater ornamental Fish in the fresh water environment in Europa countries. Gyrodactylus bullatarudis had caused the mortality in guppy ornamental fish. White Spot Disease (Ichthyophthiriosis) occurs in ornamental fish fry interprise caused the considerable economic loss. Ornamental fish were affected heavily by ectoparasites due to the very fine structure of the skin. Ectoparasites causing in ornamental fish only kills the fish but also reduces the market value of fish. The present work aim to the parasitic diseases of freshwater ornamental fish, how they are transmitted, which effects they have on ornamental fish, how they could be diagnosed, and how they could be controlled and treated.
