Polar Marine Research Institute of Marine Fisheries and Oceanography
Konstantin Sokolov was born in the former Soviet Union in 1967. His native town Murmansk is placed in the Kola peninsula on shore the Barents Sea. In 1993 he graduated from the State University in Petrozavodsk (Russian Karelia) as hidrobiologist. Since that year he works in the Polar Research Institute of the Marine fisheries and Oceanography (PINRO) in Murmansk, Russia. Now K. Sokolov is head of the Laboratory of Coastal Research.
In 2002/2003 he was trained under the United Nations University Fishery Training Programme (UNU FTP), Reykjavik, Iceland. His final project “Probable discards of cod in the Barents Sea and adjacent waters during Russian bottom trawl fishery” later formed the basis of PhD thesis “Causes and consequences of discards of the Barents Sea cod (Gadus morhua L.). Impact on the stock estimation” successfully defended in 2005.
Field of research of K. Sokolov is rather wide and boundaried inside the study of commercial demersal fish and crustacean of the Barents Sea and adjacent waters. The area of the scientific interests is generally focused on the problems of the rational fishery.
Last three years he also works as associated professor in the Murmansk State Technical University (MSTU) giving the lecture course “Rational use of the living marine resources”.
Konstantin Sokolov is author and co-author of more than 70 publications.
His main hobby is drawing.
New fisheries – new discards (exploitation of crab, typically discarded)
A new type of fishery – trap fishery for Red King Crab and Snow Crab was started in the Barents Sea at the beginning of 21st century. Both of crustaceans species were invaded in the Barents Sea ecosystem from the Pacific Ocean. The present annual Russian catch of Red King Crab is about 6.5 t. The modern international catch of Snow Crab is growing very rapidly. In 2015 it exceeded 25 thou. t. The main product is crab limbs.
During the onboard processing of crabs the significant portion of catch usually discarded back to the sea. Calculated discards constitute about 1,3-4,5 thou. t of Red King Crab and up to 8 thou. t of Snow Crab per year. A great part of these discards are chitinous carapaces but about 7% of biomass discarded are hepatopancreas and abdomen. Both of these parts are suitable for producing food and pharmacy.
