First record of American lobster (Homarus americanus) in the Adriatic Sea

The occurrence of American lobster (Homarus americanus) was reported by the fisher-man on the western coast of Istria, Adriatic Sea. In January of 2018 one specimen of American lobster was caught on north-western part of Istria (45°30.502’N, 13°28.656’E) with trammel nets at a depth of 20 m. Specimen was identified, measured, weighed, pho-tographed and tissue sample was taken for genetic analysis. Total length (TL) of the caught female specimen was 25, 8 cm, carapace length (CL) was 9, 5 cm, second abdomen segment width was 4, 9 cm and specimen weighed 499 g. Visual identification was later confirmed genetically. American lobsters (Homarus americanus) are native to the east coast of North America and Canada. They have been imported live into Europe through seafood trade. Findings of H. americanus in European waters are result of the intentional or unintentional release. In several European countries live H. americanus has been cap-tured in the marine waters. This has raised concerns about possible impact on stocks of the native European lobster (Homarus gammarus), as well as on other native crustacean species. These introductions present potential risks of disease transmission, hybridization, and/or competition for resources.
