Distribution and abundance of the holothurian Ocnus planci (Brandt, 1835) in the northern and central Adriatic Sea

Data on the distribution and abundance of the holothurian Ocnus planci in the northern and central Adriatic Sea were collected by bottom trawl during 11 cruises of the Pipeta Expedition from 1985 to 1994. A total of 518 bottom trawl hauls were performed. The species was collected at depths from 20 to 174 m. The highest mean abundance was recorded on sand-silt-clay sediment (185, 97 565, 69 N h-1) at depth stratum from 25 to 50 m.
