Gyrodactylus salaris

Gyrodactylus salaris is an extremely dangerous parasite and the ADAA is taking the most careful

steps to make sure it does not enter it’s waters. As such it is adopting the following rigorous procedures, which

we are sure you will support.

What are the risks?

G. salaris

temperatures and for 78 hours and 42 hours at salinities of 10 ppt (parts per thousand) and 20 ppt,

respectively. Risk is associated with movement of materials (animate and inanimate) that can carry low salinity

water, which have recently been in contact with infected fish, and which have been kept in cool conditions

sufficient to permit the temporary survival of the parasite away from live fish. Equipment or product that has

been kept cool and damp and is transferred rapidly (within one week) may present high levels of risk.

This parasite has destroyed the Salmon stocks of over 20 rivers in NORWAY. It was introduced to the Atlantic

coast of Norway on Baltic Sea salmon taken to fish farms there. Baltic Salmon are immune to it, Atlantic

Salmon are not – and tests have shown that Scottish Atlantic Salmon are destroyed by it just as easily as

Norwegian.

It is also indigenous to, or has been spread to RUSSIA, FINLAND, SWEDEN, GERMANY, FRANCE, SPAIN and

PORTUGAL, largely through fish-farm movements of Rainbow Trout.

It is a minute, external parasite, less than half a millimetre long and can live off fish, in the gravel, for a

considerable time, making it (as yet) impossible to eradicate from any river. Desperate methods being used in

Norway involve poisoning all the fish in a river and leaving it fallow for several months at least to try and break

the cycle. No successes have yet been reported.
