On the spatial relationship between the spawning and feeding parts of the range of lumpfish Cyclopterus lumpus (Cyclopteridae) in the Barents Sea and adjacent waters (according to results of analysis of the size composition similarity)

Results of analysis of similarity of size series of mature females of the lumpfish Cyclopterus lumpus collected on the spawning grounds in the Barents and Norwegian seas (Russian and Norwegian coasts), as well as in the areas of its feeding, are provided. The trajectories of feeding migrations of lumpfish in the southern part of the Barents Sea have been revealed. A clinal decrease in the average length of females in the range from west to east is shown. The area of feeding aggregations of lumpfish spawning off the Russian coast is distinguished. The boundaries of the census water area used to assess the commercial stock of lumpfish and to determine the values of its possible catch off the coast of Murmansk are specified.
