Резюме

In 2011 and 2012 in Subarea 88.3 Russian longliners “Sparta” and ‘Chio Maru 3” conducted research fishing for toothfish. Scientific program was carried out by scientific observers from VNIRO (Moscow, Russia) and YugNIRO (Kerch, Ukraine). Totally, during the work period 44 longlines were set at a depth from 625 to 2336 m. Total number of set hooks amounted 171096. In 2011 research fishing covered SSRU B, C and D. In 2012 ice conditions were much worse and longlines were set only in SSRU C. Collected from research fishing data contributes to the achievement of the main objectives of research - make estimation of toothfish quantity, as well as expand the knowledge about toothfish`s and by-catch species biology in this Subarea.
