and Kola Gulfs, Teriberka Bay, Drozdovka Gulf and lokanga. Great numbers of young fish pene- 

 trate into the White Sea with the littoral Murman current. The extreme points of the dissemination 

 of the herring hatched during the current year in Barents Sea are by the beginning of winter as 

 follows: western shore of Spitsbergen (near Horn Sound), south-western zone of the Central eleva- 

 tion, the shelf of Novaya Zemlya, southern slope of Goose Bank, Kanin Nos and Inlet of the White 

 Sea. During the season of movement, i.e. from spring to the beginning of winter, the herring fry 

 are carried by the current a distance of 450-750 miles from the spawning grounds, at a mean velo- 

 city of 2-3 miles a day. 



Figure 1 shows the average lengths of herring larvae in different regions and their rate of 

 growth during the drifting period. During the entire period of observations, the smallest sizes 

 (8-10 mm.) have been observed in the region of the shelf of south Lofoten Islands and adjacent 

 sections of sea. 



Figure 1 . Sizes of herring fry in different zones of the north-western 

 coast of Norway (according to the summarized data of ob- 

 servations conducted by the Polar Institute) . 



To the north-east in the region of Vesteralen Islands, larvae 10-14 mm. in length prevail. 

 To the north-east, from Ringvass^y, we found accompanying 11-13 mm. larvae a relatively great 

 number of specimens 14-18 mm. The size of larvae found farther to the north, within the 200- 

 meter isobath, is approximately the same as described above . Beyond North Cape the length of 

 larvae varies from 15-27 mm. Near the shores of Murman, herring fry are 40-50 mm. in length. 

 In the autumn, the young herring hatched during that year reach 70-90 mm. in length.
