Morska fauna Nacionalnog parka Mljet (Jadransko more, Hrvatska) 5. Mollusca: Bivalvia.

A 130 bivalve species from 38 families were recorded in the Mljet National Park during research carried out from 1995 to 2002. In situ observations and collections were realised by skin and SCUBA diving at 63 sites, to a maximum depth of 58 m. At 21 stations bivalves were collected by Van Veen grab, at six stations by trammel bottom sets and at one station outside the borders of the National Park by a commercial bottom trawl. For each species, the general distribution, depth range, habitat, ecological data and significant remarks are presented. Records published previously were reviewed and a bivalve check-list for the Mljet National Park with a total of 146 species belonging to 39 families was generated. Listed species account for about 70% of bivalves noted in the Adriatic Sea. Sixty-one species were recorded for the first time in the Mljet Island area. One juvenile individual of an Indo-Pacific species Semipallium coruscans coruscans (Hinds, 1845) was recorded for the first time in the Mediterranean. Some species rarely noted for the Adriatic Sea, and also rarely recorded at the stations surveyed were Nuculana pella, Palliolum striatum, Pseudamussium sulcatum, Limatula gwyni, Thyasira granulosa, Astarte sulcata, Venus casina, Globivenus effosa, Clausinella fasciata, Lajonkairia lajonkairii, Mysia undata, Thracia villosiuscula, Cardiomya costellata, Ennucula aegeensis, Barbatia clathrata, and Galeomma turtoni.U Nacionalnom parku Mljet utvrđeno je tijekom istraživanja provedenog od 1995. do 2002. godine 130 vrsta školjkaša iz 38 porodica. Na 63 obalne postaje školjkaši su bilježeni i sakupljani metodom autonomnog ronjenja, do dubine od 58 m. Na 21 postaji se uzorkovalo pomoću grabila Van Veen, na jednoj postaji s pridnenom koćom, a na šest lokaliteta su školjkaši izvađeni iz ribarskih mreža poponica. Za svaku vrstu se navode podaci o njenoj lokalnoj rasprostranjenosti, dubini, staništu, ekološkim značajkama i značajnijim opažanjima. Izra|ena je lista školjkaša za područje Nacionalnog parka Mljet sa 146 vrsta iz 39 porodica u kojoj su obuhvaćeni i prethodni literaturni podaci. Navedene vrste predstavljaju oko 70% školjkaša zabilježenih u Jadranskom moru. 61 vrsta nađenih školjkaša je prvi puta zabilježena za područje otoka Mljeta. Jedna indopacifička vrsta Semipallium coruscans coruscans (Hinds, 1845) nađena je po prvi puta u Sredozemnom moru. Na|ene su i vrste koje su rijetko zabilježene i u Jadranskom moru. To su: Nuculana pella, Palliolum striatum, Pseudamussium sulcatum, Limatula gwyni, Thyasira granulosa, Astarte sulcata, Venus casina, Globivenus effosa, Clausinella fasciata, Lajonkairia lajonkairii, Mysia undata, Thracia villosiuscula, Cardiomya costellata, Ennucula aegeensis, Barbatia clathrata i Galeomma turtoni
