Research catching was carried out in SSRU B, C, and D. In SSRU A sets had not took place because of complicated ice conditions. The catch was totally analyzed for its biological characteristics. Additional catch’s biological characteristics have been analyzed too (excluding fish food analysis). According to the catch’s length variation, 30 fishes of different length have been tagged. Total catch is 256 toothfishes – 5230 kilograms weight. Data about spatial and bathymetrical distribution and nutrition of toothfish in subarea 88.3.B-D were collected 240 otolithes for age identification, 53 genetic specimens and 42 histological specimens have been collected.
