Scientific survey catch data: Bentho-demersal assemblages of Sardinia (Mediterranean sea) in 1963
This dataset contains an inventory of bentho-demersal fauna captured by bottom trawling in the north of Sardinia. There are also counts, measurements of weight, length and sexe determination of individuals.
This exploratory bottom trawl survey aimed at evaluating the fishing possibilities in the region. Unfortunatly the exact location of each station could not be recovered.
According to Maurin and Bonnet (1964), this survey carried out in November and December 1963 enabled to locate high yield deep shrimps’ areas off the coasts of Sardinia, in particular the south coast between the capes Spartivento and Sperone, the west coast between the cape Sperone and the gulf d’Oristano and between the capes Mannu and Argenteria and the north-east coast off cape Ferro.
The survey was carried out at depths ranging from 90 to 600 m as follows:
- from 9 to 16 November, the RV Thalassa worked off the south coast and the south-west coast as far as the latitude of Bosa (40°15 north latitude);
- from 5 to 7 December, the RV Thalassa trawled off the north-east coast;
- from the 11th December onward, the RV Thalassa operated off the north-west coast between Bosa and Cape Falcone.

Devices
The sampling strategy is described in Maurin and Bonnet (1964). Two different bottom trawl were tested:
A bottom trawl of the ‘Ville de Safi’ type, made of braided nylon, with 29 m of headrope and 42 m of ground gear and a trawl with a wide vertical opening with two asymmetrical wings, mounted on a double ground gear; this net was used either as a semi-pelagic or as a bottom trawl with a 20mm mesh size in the cod-end. They systematically target bentho-demersal species.
