The ornamental fish industry transfers large quantities of fish between countries. Due to the largely unregulated nature of this trade, it presents considerable potential for transboundary transfer of disease agents. Although tropical ornamental fish are usually kept in indoor aquaria and are unlikely to survive for long if released into the environment of temperate regions, they are capable of carrying viruses that pose a threat to temperate fish species. Of particular concern are ranaviruses, which have been reported in several tropical ornamental fish. Some of these ranaviruses are highly pathogenic to certain temperate fish species, both farmed and wild. The so-called 'cold-water ornamentals' are fancy varieties of common species, mostly cyprinids, which do survive and breed in temperate waters, as well as in tropical countries. The most widely traded of these species internationally are goldfish (Carassius auratus) and koi carp (Cyprinus carpio koi) and both species have been implicated in trans-bo'undaxy transfer of viral diseases. Most recently, koi herpes, which is capable of causing large-scale mortalities not only in koi carp, but also in common carp varieties fanned for consumption, has been spread to several countries via this trade. The ornamental fish trade is also suspected in the first introduction of the OIE notifiable disease: spring viraemia of carp (SVC) to the USA. Such events are likely to lead to increased demands for health certification for ornamental fish, which may in the short term cause restrictions on the trade; however, in the long term it is likely to aid the sustained development of the ornamental fish industry.
