V. Piačková, E. Zusková (LATI) and E. Sancho Santos (LECHB) spent four days (9-12th September) in Oporto (Portugal) for the attendance to the “19th Conference on Diseases of Fish and Shellfish”, in which we presented three posters. Furthermore, we had the opportunity to update our knowledge concerning fish health and open a prospective international cooperation with colleagues related to the field.
