LIST OF VESSELS 


  In total 23 units were built from 1973 to 1975, at Poland. Also from 1976 to 1977 were built four fishing freezer trawlers of B-422/II design.
  Vessel "Mezen" in 1992 was converted to seismic survey vessel.

  Trawler "Berezina" caught fire on January 29, 1975. "Serebryanka" and "Zverevo" were grounded near Korsakov.
Purpose of the vessel:     - pelagic and ground fishing
    - sea hunting for walruses and seals
    - production of frozen fish, fish meal, veterinary oil, skins and frozen meat
    - transport of processed cargo to port
