The idea of making a fish atlas for the Barents Sea fishes came about when organizing and working with fish data from the Joint IMR–PINRO ecosystem survey. The Joint IMR–PINRO ecosystem survey is the most comprehensive survey that IMR and PINRO have conducted together, and carried out with 4-5 research vessels each year in August-September. The data from this survey in the years of 2004-2009 was used in here. The structure and content of the “Atlas of Barents Sea fishes” is strongly influenced by the “Atlas of the North Sea Fishes” by Knijn et al (1993), brought to our attention by O.A. Bergstad.
