Trawlings during NOVOUKRAINKA cruise NOV3, Part I

DOI

The fish catches were carried out by the industrial midwater non-closed trawl. There was a small-mesh section with minimum mesh size of 6.5 mm in the trawl bag. Vertical opening of the trawl made from 26 to 50 m. The trawling made 30 min up to 2 hour and 30 min. Speed of trawling made 3.2-4.2 knots. The catches horizons were determined by the state of sound-scattering layers and fish schools. At night they carried out catches usually in the upper 0-550 m layer. At the day time they trawled at a range of 60-490 m depths. 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.
