Distribution of Atrina fragilis (PENNANT, 1777) (Pinnidae, Mollusca, Bivalvia) in the Adriatic Sea
The bivalve Atrina fragilis was collected by means of bottom trawl during 17 cruises of PIPETA Expedition in the Adriatic Sea in the period from 1982 to 1994 on the surface of 59000 km2 of continental shelf. A total of 780 hauls were done. Atrina has been recorded at 20% of bottom trawl hauls. The species is the most abundant on sand-silt-clay and clayey &#8220 ; relict&#8221 ; sand in depths between 25 i 50 m. The deepest occurrence was between 251 i 256 m. In spite of intensive trawl fishing and occasional hypoxia events Atrina is renewing.
