Help us keep our fish healthy from gyro

Published 12.10.2012     Modified 12.06.2018

Gyrodactylus salaris is a tiny creature which is often referred to as the "salmon killer" or simply "Gyro". The effects of this parasite are so serious for the salmon that it can disappear completely from the infected rivers.

For this reason it is very important that everyone who is out and about around rivers and fresh water knows what to do. We all have to do our bit to ensure that this parasite doesnot spread to other rivers.

  • The transfer and release of fish is prohibited without permission from The Norwegian Food Safety Authority or the County Governor.
  • Do not wash or gut fish anywhere other than where you caught it.
  • Moving equipment between or within water systems without first drying or disinfecting it is prohibited.
  • Do not pour water out anywhere other than where it was collected.

Make sure to do the following before moving equipment between/within water systems:

Visit a disinfection station and have the equipment disinfected,

or

disinfect it yourself using Virkon-S (available from e.g. Felleskjøpet). Dissolve Virkon-S in water to make a 1% solution, apply to the equipment and rinse off after at least 15 minutes. Virkon-S is known not to damage equipment. Follow the instructions on the packaging or contact The Norwegian Food Safety Authority for more information,

or

make sure that all equipment is dry before moving it to the next water system. This applies to fishing tackle, landing nets, boats, boots and any other equipment that has been in contact with water.

Kayakers must dry or disinfect their equipment

All canoers must dry and/or disinfect kayaks and any other equipment that has been exposed to water using Virkon-S (available from e.g. Felleskjøpet) before moving them to other rivers.

Dissolve Virkon-S in water to make a 1% solution, apply to the equipment and rinse off after at least 15 minutes. Virkon-S is known not to damage equipment. Follow the instructions on the packaging or contact The Norwegian Food Safety Authority for more information,

Failure to do this may result in a ban on sporting and leisure activities in gyro-infected rivers in Norway. Disinfection protects rivers and safeguards the right of canoers to use them.
