herring caught with large-meshed nets in commercial quantities. In certain cases, the catches of 

 fat herring reached 5 and even 8 tons per vessel per day. 



Figure 2 shows the results of observations on the distribution of fat herring during the 

 period of 1939 to 1953. Fat herring were found in a greater or lesser number in almost all the 

 zones of the Norwegian Sea, as well as in Spitsbergen current, approximately up to 75-76° north 

 latitude. The maximum incidental catch of fat herring was in commercial catches from the western 

 branch of the Norwegian current, near Mohn's Threshold, southerly and southeasterly from Jan 

 Mayen.

 land seas as observed by the Polar Institute in 1939-1953. I. In samples obtain 

 ed from catches of less than 1 ton. 1 - one to two specimens; 2 - up to 5 speci- 

 mens; 3 - up to 10 specimens; 4 - up to 25 specimens; 5 - up to 50 specimens; 

 6 - more. II. For the samples obtained from catches of more than 1 ton the 

 indices are encircled.
