Abstract Vibrio anguillarum, which is considered to have world-wide distribution, is responsible for significant fish losses in commercial aquaculture. Samples of water, sediment, macroalgae, and salmon from selected New Zealand sites were tested for the presence of Vibrio anguillarum. Thirty-seven isolates were identified andcharacterised using biochemical, restriction endonuclease, pilasmid, and serological analyses and compared with twonorthem hemisphere pathogenic strains of V. anguillarum. New Zealand V. anguillarum isolates differed at the molecular level and antigenically from these pathogenic strains. The differences are interesting in terms of the taxonomy of this species arid in the use of vaccines to control V. anguillarum.
