Ship (station) name: R/V "Professor Vodyanitskiy" (IBSS, USSR)

Expedition: the10-thexpedition, January - May, 1981
 
Parameters:  up to 6 character unique sample identifier:
Species  total number of specimen in sample;
Count  number of specimens in sample;
Full Weight  total weight of species in sample in g;
Avg Weight  average dry weight of species in sample in g;
Length min  minimum standard length of species in mm;
Length max  maximum standard length of species in mm.

Instruments and methods: 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 weight of each species in a catch, and average dry weight 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.
