Keep Koi Herpesvirus out!
With the holidays well underway and people jet setting around, some fish enthusiasts may become tempted to bring fish home illegally. Please refrain from doing this. Of greatest concern because of its ability to spread widely and quickly is a disease of koi. Koi herpesvirus disease affects all varieties of common carp Cyprinus carpio, including varieties such as mirror, leather, koi, and ghost koi. Mortalities are usually 100% and there is no treatment. Clinical signs include listlessness or erratic behaviour, loss of balance, loss of mucus (resulting in dry, rough patches, sloughing of mucus), and sunken eyes. Gills are most frequently affected displaying patchy areas of necrosis (dead tissue), often with secondary infection of bacteria and fungi.
