Methods

Bottom trawl surveys in Russia's economic zone in the north-western part of the Bering Sea were conducted in 2005 2008 2010 and 2012 on research ships such as STM (Project 833 NIS TINRO and NIS Professor Kaganovsky) with the crew on each vessel in an amount of 51-55 people including research staff of 12-16 people depending on the amount of scientific work. Bottom trawl surveys were carried out under the standard scheme trawl stations and methods [17]. The path traveled by ship to trawl from touching the ground up to the job it was determined by the electronic chart system (ECS) Transas. In the course of trawl trawling position controlled device Igla (2005 and 2008.) ?Simbia 110-2? (2010) and ?SIMRAD FS 20/25? (2012). All-time survey covered the summer-autumn period from July to September-October but they were made with some time discrepancies (07.08-12.10.2005 10.07-06.09.2008 17.07-25.08.2010 and 08.07-26.08.2012). 817 bottom trawling were carried out. Calculating abundance and biomass of bottom fish performed by the standard method of areas and its modifications [1] using the areas of polygons corresponding to each trawling (Voronoi-cell Dirhle or Thiessen polygons). At the same time we take into account the basic bathymetric ranges of gradations of 50 or 100 m. Between isobaths on the shelf and continental slope at depths up to 1000 m. For each type of calculated average value of their catches in the piece and weight na1km2 expressions. Biological Assays and mass measurements of fish were carried out according to standard methods of ichthyological research.
