The fish catches were carried out by the scientific midwater non-closed trawl. There was a small-mesh section with minimum mesh size of 0.14-0.09 mm in the trawl bag. Vertical opening of the trawl made up to 6 m. The trawling duration under catches in the sound-scattering layers made 1 hour. Speed of trawling made 3.0 knots. The catches horizons were determined by the state of sound-scattering layers and they carried out in 20-86 m. Each catch was weighted. Fish was determined up to the lowest taxonomic ranks - species, in some cases - genus. Total number and mass of each species in a catch, and average dry mass of one specimen of a species were determined. The standard fish body length (SL) was measured in mm (from the tip of snout to the basement of the middle rays of the caudal fin). The samples were fixed in 10% buffered formaldehyde for further processing in the IBSS laboratories.
