Abstract

Between June 5th 1957 and July 4th 1958 a series of trawl-surveys were organised by the Institute of Oceanography and Fisheries (IOF, Croatia) in the Croatian channels around the Hvar Island (central-eastern Adriatic).
Tows were performed once a month in all of the 10 fixed stations, for a total of 120 hauls. Two motorboats were employed, “Bios” (300 HP; LOA = 26 m) and “Predvodnik” (200 HP; LOA = 19 m). A cotton bottom otter-trawl net was used (wing mesh-size: 57 mm; cod-end mesh-size: 22 mm; foot-rope length: 34 m; head-rope length: 28 m). Tow duration was one hour for all hauls. CPUE (n/h) indexes for 104 demersal species were recorded (6,718 records), as well as information on the sediment type at each station. Species synonymies were updated according to the modern nomenclature referring to the World Register of Marine Species (WoRMS). Some species are grouped into multispecies categories that group taxonomically similar species, i.e. species of the same genus or family (e.g. Raja spp., Triglidae). Sediment samples were collected by means of the Peterson power shovel. The depth of each station was extracted from the EMODnet Digital Bathymetry.
