Report of a Workshop on Gyrodactylus salaris in the Commission Area 1. The parasite Gyrodactylus salaris (G. salaris) is a very serious parasite that strikes at the very heart of salmon conservation. In Norway the parasite has infected 44 watercourses and the average decline in parr densities in these rivers has been 86%. The parasite has also been identified in 13 of the 23 rivers on the west coast of Sweden, in the rivers Keret and Kem in Karelia, Russia, and in watercourses in northern Finland, although not the two main Atlantic salmon rivers in the region, the Tenojoki (Tana River) and Naatamojoki (Neiden River). Iceland, the UK and Ireland are free of the parasite but it is known that Scottish stocks are as susceptible to the parasite as those in Norway. 2. The Commission accepted an invitation from the Directorate for Nature Management, Norway, to hold a workshop with the intention of:- reviewing information on the monitoring programmes for, and on the distribution of, G. salaris;- reviewing measures implemented and proposed to minimise the threat posed by G. salaris, including details of treatment methods employed;- developing recommendations on opportunities to enhance cooperation on monitoring, research and exchange of information;- developing recommendations on the need for revisions to international guidelines and other measures and for strengthening of national and regional legislation and measures with the objective of preventing the further spread of the parasite.
