A total of 82 trawl stations were conducted during the survey, comprising 74 demersal trawls and 8 pelagic trawls across a depth range of 26 to 777 m. Of these, eight stations were conducted at depths greater than 500 m. One station was deemed invalid due to excessive mud clogging the net, which prevented proper processing of the catch.
The trawl survey recorded a total of 808 taxa, and 7,667 individual organisms were measured for length and weight. Occasional occurrences of marine litter were also observed within the trawl catches and were documented accordingly.
Three trawl systems were used during the survey: a small four-panel Åkrahamn pelagic trawl, a MultPelt 624 pelagic trawl (introduced in 2017), and a Gisund super bottom trawl. The smallest pelagic trawl typically operates with a vertical opening of 8–12 m, while the MultPelt 624 achieves a vertical opening of 25–35 m under normal conditions. The bottom trawl is equipped with a 31 m headline and a 47 m footrope fitted with 12-inch rubber bobbins gear. The codend has a mesh size of 24 mm, with an approximate vertical opening of 5.5 m, a wing spread of ~18 m, and 40 m sweeps. Thyborøen combi trawl doors (8 m², ~2000 kg each) were used, providing a door spread of approximately 45 m when a restraining rope is applied; however, no restraining rope was used during this survey, as sampling was conducted for species identification purposes only.
Trawl performance and geometry were continuously monitored using the SCANMAR system, consisting of acoustic sensors, a hydrophone, a receiver, a display unit, and a power unit. Acoustic communication between sensors and vessel enabled real-time monitoring of gear behavior. Door sensors provided inter-door distance and angle measurements, while a height sensor on the bottom trawl recorded net opening and bottom clearance. A trawl eye system provided additional information on footrope height above the seabed, and a pressure sensor recorded headline depth throughout each tow.
