To study the distribution of Icelandic scallops (Chlamys islandica) in upper subtidal zone (depth less than 40 m) along the Barents Sea coastal line of the Kola Peninsula, a series of diving surveys was conducted in 2002-2006. The scallops were founded at depth more than 1 m along whole studied coastal line. The total number of scallops on total area 1 177 km2 was estimated to 428 million specimens, of them 260 million specimens or 18,3 thousand tons was a commercial stock. 70% of the commercial stock is located at the Western Murman. The weighted average biomass of commercial scallops was 15,5 g per m2 (21,1 g per m2 at the Western Murman and 9,9 g per m2 at the Eastern Murman). The commercial scallops can form local dense accumulations up to 30 specimens per m2 (4 kg per m2) in the upper subtidal zone
