Ornamental Fish International o Red sea bream iridoviral disease o Koi herpesvirus disease (KHV) All of these diseases have been studied to see which fish species are susceptible Only three diseases mention ornamental fish among the susceptible species, SVC, EUS and KHV. Spring Viraemia of Carp Spring Viraemia of Carp (SVC) is a disease caused by a Rhabodvirus, which can be found in carp-like fishes only: common carp including koi (Cyprinus carpio), crucian carp (Carassius carassius), sheatfish (also known as European catfish or wels) (Silurus glanis), silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis), grass carp (white amur) (Ctenopharyngodon Healthy lionhead oranda, free of SVC.

Outbreaks are known to have occurred in Europe, the USA and Asia, including China in ornamentals such as goldfish and koi. The mortality due to this disease is high, in young fish it can reach 70%, and for this reason it is perfectly understandable that measures are taken, especially if we think of the importance of carp as food fish. Unfortunately SVC and other diseases do not make a distinction between carp sold as an ornamental fish or as a food fish. Epizotic Ulcerative Syndrome Epizotic Ulcerative Syndrome (EUS) is a disease which is present in large parts of Southeast Asia in a wide variety of fish: yellowfin seabream (Acantopagrus australis), climbing perch (Anabas testudineus), eels (Anguillidae), bagrid catfishes (Bagridae), silver perch (Bidyanus bidyanus), Atlantic menhaden (Brevoortia tyrannus), jacks (Caranx spp.), catla (Catla catla), striped snakehead (Channa striatus), mrigal (Cirrhinus mrigala), torpedo-shaped catfishes (Clarius spp.), halfbeaks flying fishes
Legislation (Exocoetidae), tank goby (Glossogobius giuris), marble goby (Oxyeleotris marmoratus), gobies (Gobiidae), rohu (Labeo rohita), rhinofishes (Labeo spp.), barramundi and giant sea perch (Lates calcarifer), striped mullet (Mugil cephalus), mullets [Mugilidae] (Mugil spp. and Liza spp.), ayu (Plecoglossus altivelis), pool barb (Puntius sophore), barcoo grunter (Scortum barcoo), sand whiting (Sillago ciliata), wells catfishes (Siluridae), snakeskin gourami (Trichogaster pectoralis), common archer fish (Toxotes chatareus), silver barb (Puntius gonionotus), spotted scat (Scatophagus argus), giant gourami (Osphonemus gourami), dusky flathead (Platycephalus fuscus), spiny turbot (Psettodes sp.), Tairikubaratanago (Rhodeus ocellatus), Keti- Bangladeshi (Rohtee sp.), rudd (Scardinius erythrophthalmus), therapon (Terapon sp.) and three-spot 83 Ornamental Fish International Trichogaster pectoralis, known to be susceptible to EUS. Photo: Aqualog gouramy (Trichogaster trichopterus). The disease is caused by a fungus, Aphanomyces invadans. Despite the large area where it is present in natural fish stocks, it is rarely found in imports. This is most likely due to the secondary bacterial infection of the fish infected with EUS. The secondary bacterial infection is easily recognised and treated. The mortality rates due to EUS are not known, however, the impact is considerable. Koi Herpes Virus disease Koi Herpes Virus disease (KHV) is distributed almost worldwide now and has become such a hazard to our industry that most of you will know about this disease, which can cause up to 95% mortality in carp (Cyprinus carpio) only. The problem with this disease is that it is mainly active between
