2 Active monthly salmon sea sites Ene Feb Mar Abr May Jun Jul Ago Sept Oct Nov Dic Año Año

3 Salmon sea sites by species 2016 Coho Trout Salar

4 Chilean Animal Health control strategy in aquatics To prevent presence of diseases Early detection Inmediately notification Rapid response Responsible and prudent use of antimicrobials products Control and enforcement Reporting and transparency

5 OIE Chile status Contry free 1. Epizootic haematopoietic necrosis disease 2. Infection with Aphanomycesinvadans (EUS) 3. Infection with Gyrodactylus salaris 4. Infection with salmonid alphavirus 5. Infectious haematopoietic necrosis 6. Koi herpesvirus disease 7. Red sea bream iridoviral disease 8. Spring viraemia of carp 9. Viral haemorrhagic septicaemia. Diseases never reported in Chile

6 OIE Aquatic Code and Manual based Since 2003 Active Surveillance Sampling 5% of prevalence and 95% of confidence Accreditated laboratories Sernapesca supervision Wild testing program since 2010

12 Diseases present in Chile

13 Diseases presents in Chile ISA (OIE listed) IPN Renibacteriosis (BKD) Piscirickettsiosis (SRS) Sea lice

14 Infection with HPR-deleted or HPR0 infectious salmon anaemia virus (ISA)

15 Summary status 2 outbreaks, 50% cases less than 2015 Same variants (previous present in Chile) HPR 8 y 7b The cases were only into the same macrozone without disemination Early detection and rapid implementaction of control measures (with the present of the virus without clinical signs or mortalility) ISA HPR0, same trend in incidence ( 29% monthly)

39 New regulation to control masive mortalities

40 Our main challenge:

41 General Sanitary Program The program covers four areas and sets specific actions to be taken in the veterinary field. Promote its rational use To secure availability and increase effectiveness of antimicrobial agents Promote animal welfare Economic need to control diseases that affect salmon farming, especially SRS. Monitoring and prevention of AMR Strengthening control of antimicrobial residues in products

42 The lowest consumption index of the last 4 years

43

44

45 Antimicrobial free program

46 Disease Epidemiology Public and strategic research Diffusson Microbiology and Parasitology Pharmacology and Genomic Host response Focuses on disease (SRS), prevention and monitoring of resistence and to extend the effectiveness of antimicrobial agents New center for salmon diseases, Budget US$ 24 MM Center aimed at process and build predictive models with sanitary and environmental data, Budget US$MM 9 with CSIRO Australia
