Abundant resources of cod and haddock along the Murman coast and in the White Sea were already being fished for from early times. Most of the fishermen were Pomores. A large part of the catches were salted or dried to stockfish. Pomores travelled each summer to Norway for bartering. Arkhangelsk in a while became a centre for the fish trade within the country. So far the fisheries had been limited to coastal waters and produced relatively small quantities. In 1924 a commercial fishery in the Barents Sea began to operate from Murmansk. Murmansk was always a very important strategic port of waters influenced by Gulf Stream never freeze, which allowed fishing vessels to catch and bring fish to the shore all year around.
