We participated at the EUROBUS workshop, organized in Naples from 29-30 January 2018 by the Stazione zoologica “Anton Dohrn”. The main objective of the meeting was to coordinate the efforts of scientists and institutions working on monitoring of the invasive planktonic copepod Pseudodiaptomus marinus, which is expanding rapidly through the European seas.
