Spring Viraemia of Carp (SVC), GOLDFISH virus Options

[Mortevicar]

You may or may not be aware that the deadly fish disease Spring Viraemia of Carp (SVC) has been discovered in imports of goldfish brought into the UK from a Hong Kong aquarium fish supplier.

Defra has confirmed that routine import checks have identified the virus in a consignment of goldfish imported from Tung Hoi Aquarium Company, Hong Kong.

Other fish from the same supplier have been purchased by fish dealers, potentially aiding the spread of the virus through the aquarium trade.

Australia also imports from Tung Hoi - I have lost nearly ALL of my fish with the same symptoms in the last few days: bleeding through gills, white stringy faeces, protruding anus, lethargy. I purchased two fish from an aquarium that imported from Tung Hoi one month ago. It also makes sense as to why there are not many fish available as most importing has stopped because of the virus.

In natural outbreaks, mortalities were confirmed in spring when water temperatures ranged from 12°C to 22°C (54°F to 72°F).

The optimum temperature for viral replication in vitro is 20-22°C (68-72°F), however, this is also an optimum temperature range for immune function of susceptible species.

Clinical and experimental data indicate that maximum mortality can be expected at water temperatures below 18°C.
