4. Passive surveillance (2006/88) Passive surveillance shall include mandatory immediate notification of the occurrence or suspicion of specified diseases or of any increased mortalities. In such cases investigation in accordance with Section 2 of Chapter V shall be required.

5. Active surveillance (2006/88) Active surveillance shall include: (a) routine inspection by the competent authority or by other qualified health services on behalf of the competent authorities; (b) examination of the aquaculture animal population on the farm or in the mollusc farming area for clinical disease; (c) diagnostic samples to be collected on suspicion of a listed disease or observed increased mortality during inspection; (d) mandatory immediate notification of occurrence or suspicion of specified diseases or of any increased mortalities.

6. Targeted surveillance (2006/88) Targeted surveillance shall include: (a) routine inspection by the competent authority or by other qualified health services on behalf of the competent authorities; (b) prescribed samples of aquaculture animals to be taken and tested for specific pathogen(s) by specified methods; (c) mandatory immediate notification of occurrence or suspicion of specified diseases or of any increased mortalities.

7. Targeted surveillance in Croatia (2006/88) Implemented from 2010 on all farms with susceptible species to: –VHS/IHN –KHV –Infection with Bonamia ostreae

8. Risk based animal health surveillance (2006/88) The risk-based animal health surveillance scheme referred to in shall aim at the detection of: (a) any increased mortality in all farms and mollusc farming areas as appropriate for the type of production; And; (b) the diseases listed in Part II of Annex IV, in farms and mollusc farming areas were species susceptible to those diseases are present.

9. Risk assesment on all farms Future plans (2014): Risk based surveillanceRisk based surveillance

10. Sample size (2001/183) Model A — two-year surveillance programme Following at least two years of absence of any clinical or other sign of VHS and/or IHN, all farms in the zone or any farm in a non-approved zone which are to be approved must be health-inspected twice per year for two years. During this two-year control period, which precedes achievement of approved status, the absence of clinical or other signs of VHS and/or IHN must have continued and samples must be collected for examination in accordance with Table 1A. Further, the samples must be selected, prepared and examined as described in Parts I.I to I.IV and the laboratory examinations must have produced negative results for VHS and/or IHN;Table 1A

12. Sample size (2001/183) Model B — two-year surveillance programme with reduced sample size Following an official health inspection programme documenting the historical freedom from VHS and/or IHN for at least four years, all farms in the zone or any farm in a non-approved zone which are to be approved must be health-inspected twice per year for two years. During this two-year control period, which precedes achievement of approved status, the absence of clinical or other signs of VHS and/or IHN must have continued and samples must be collected for examination in accordance with Table 1B. Further, the samples must be selected, prepared and examined as described in Parts I.I to I.IV and the laboratory examinations must have produced negative results for VHS and/or IHN. In order that a health inspection programme might be recognised by the official services for documentation of freedom with regards to VHS and/or IHN, it must fulfil the criteria and guidelines set out in Part III.
