Questionnaire on Survey and Diagnosis of Fish Diseases in Europe 2023

Monday 12 Feb 24

It is time for the EURL to collect the annual data for Survey and Diagnosis, to get an overview of the status of diseases listed in Europe, according to Commission implementing regulation 2022/925.

Every year the EURL collates data provided from the National Reference Laboratories (NRLs) about aquaculture production, number of outbreaks of listed fish diseases, health category status of fish farms, fish health challenges occurring in the different countries and number of test conducted by NRLs.


The NRL's should return the completed questionnaire to the EURL no later than 19th April 2024.

How to fill in the template

The template for collecting data in 2023 is aligned with the Animal Health Law:

  1. The EURL team will retrieve all general production data in Europe by combining the FAO Fisheries Global Information System (FIGIS) and the annual report provided by Federation of Aquaculture Producers (FEAP).

  2. The general production data do not cover the number of farms with susceptible species nor their health status. These information are important for epidemiological analysis. Therefore, the EURL asks each Member State to provide these data. It is the responsibility of the NRL to collect these data from the respective authority in their country.

  3. The EURL would like to collect information on the geographical localization of zones and compartments within the different health categories in each country. Therefore, the NRL's are encouraged to submit a map with this information. Maps can be retrieved from nationsonline. org, but the NRL's are free to use the map that fits their needs best.

  4. All Member States are asked to use the S&D 2023 Excel template. The file should be saved with the name of the country and submitted to Thomas Weise ( and Niccolò Vendramin ( latest 19th of April 2024. 

  5. With specific reference to points 3.3; 3.4 and 3.5 of the questionnaire, the NRL's are asked to fill these fields only if specific changes have occurred since last year.
