I 32 Few comments. Nodavirus infection in Sea Bass AngHV-1 in Eel Ranavirus in catfish Greece Seabass VNN/VER Hungary Ameiurus nebulosus ranavirus Netherlands eel, Anguilla anguilla 2 x AngHV1 with typical symptoms Decrease in number of VHS, IHN and KHV infected farms in Austria and decrease in severity! No VHS any more in Estonia Czech Republic Increase with 9 VHS outbreaks and 4 IHN outbreaks 28 farms under eradication program. No new VHS cases in 213 or 214! : No changes in most states but some experienced increases and some decreases, including dobbeltinfections with VHS and IHN. Netherlands: Decrease no VHS or IHN outbreaks reported Is there an increase or decrease in the number of fish farms infected with listed diseases compared to previous years? II Is there an increase or decrease in the number of fish farms infected with listed diseases compared to previous years? III England & Wales: The major cause of concern in the UK trout sector is the emergence of skin conditions in rainbow trout which, which whilst may not cause in significantly increased mortality, result in economic losses to fish farmers due to high level of rejections at processing or rejections for restocking recreational fisheries. : Decrease in farms infected with VHS - all sites have depopulated and fallowed (virus isolated from wrasse held on sites for biological control). Croatia: Yes, after outbreak of VHS on the single farm, and IHN on the other, the diseases have spread to another farms; finally there are 3 VHS infected farms and 4 IHN infected farms : List 3: PD increase from 1 cases in 213 to 142 cases in 214. Faroe Islands: Yes. For the first time since the ISA epidemic 1 years ago one farming site was tested positive for a ISAV-HPRdel. But no clinic was observed and the site was emptied within 2 weeks Switzerland: In contrast to 213 () in 214 one case of VHS was detected. In one farm IHN was found compared to two infected farms in the previous year. 35 No. of samples tested by cell cultivation. Steady decrease Total in Europe = fish samples 213 Total in Europe = fish samples No of samples tested by PCR or other direct methods without cell cultivation. Steady increase Total in Europe = in 213 Total in Europe = in

7 Conclusion on S&D 214 No increase in marine production, and very stable fresh water production. Few changes from 213 to 214. Unfortunately some Member states did not reply in full IHN resolved in Hungary VHS and IHN in Croatia Eradication program for VHS in, no outbreaks in 213 and 214 Still several ISA outbreaks in with 3 infected farms ! 1 ISA-deleted I Faroe Islands without clinics Skin distress a major problem in RT production This year, thanks to Niccolò raw data are included in the folder this year. All data can be retreived from our web site: In Surveillance and diagnosis 38 Thank you for all the significant work, efforts and time used for compiling these data!! Thank you for your attention! 7
