In the Viking Bank region and north from It, along the slope of the continental shelf, Clark 

 (38) found herring eggs in the guts of haddock. During the spring, we also found freshly-hatched 

 herring larvae in this region. 



In February - early March, 1952-1955, Soviet boats fished the pre-spawning herring con- 

 centrations on the Viking Bank with drift-nets. A great number of specimens with running sexual 

 products were found in these catches. On February 27-28, 1953, the author of the present article 

 succeeded in observing a rather interesting spawning on the south-eastern slope of the bank, at a 

 water temperature of approximately 7°C. In 1952 and 1953, German trawlers (71) fished herring 

 with herring trawls on the Otter Bank. The average catch per boat per day was 13-16 tons in 

 February-March; this is confirmation that large concentrations of the pre-spawning herring of this 

 region are present in the deep layers. As a result of special investigations established under the 

 supervision of 1. G. Yudanov and carried out by the Polar Institute in February-March, 1955, on 

 board the exploratory boats "Professor Mesyatsev" and "Academician Berg", our knowledge of re- 

 production of Atlantic -Scandinavian herring became considerably enriched. 



A great number of herring larvae in early stages of development were found on the Otter 

 Bank, to the west of the Shetland Islands, in the region of the continental slope where the depths 

 reach approximately 200 meters, at a temperature of approximately 7° and a salinity of 35.3.. 



Herring spawning in the region of the Faeroes was established by Tfining (77) and Clark 

 (39). The larvae of spring-spawning herring were found here in March, April and May. The 

 largest catches of larvae were obtained near the eastern shores of Sudero Island within the limits 

 of the 50-meter isobath at a temperature of 5-7°C and salinity of 35.1-35.3. 



Concentrations of herring with running sexual products were found on bank "192" to the 

 north-east of the Faeroes, at the end of March, 1952, by B. V. Istoshin, scientific member of the 

 Polar Institute, during exploratory operations on board the "Musson". 



In the latter half of March, 1955, exploratory boats fomid a considerable quantity of herring 

 with running sexual products to the north-east and east from the Faeroes, in the region of the 

 200-meter isobath. 



In mid-April in that region, A. P. Vilson, a scientific member of the Polar Institute, while 

 on board the expedition boat "Academician Berg", found herring larvae present at early stages of 

 development . 



The study of herring reproduction in the Icelandic region was begun at the beginning of our 

 century by I. Schmidt, who conducted scientific-commercial explorations on board the expedition 

 boat "Tor" in that area between 1903 and 1908. Data collected in the course of this research were 

 analyzed at a much later date by Espersen (51) and published in 1920. 



From 1924 until most recently, herring- spawning near the shores of Iceland was period- 

 ically studied by TSning (78, 80). Brief reports on herring reproduction in this region were also 

 written by Fridriksson (42, 44). 



The reproduction in the region of Iceland of the Atlantic -Scandinavian spring-spawning her- 

 ring was experimentally proved on several occasions. In April 1904, Schmidt caught more than 

 2,850 larvae, 7-8 to 15 mm. in length. In April 1925, the boat "Filla" caught at three stations 142 

 larvae, 6 to 14 mm. in length in surface tows. Between March 27 and April 3, 1950, Fridriksson 

 found developing eggs at a depth of 6 to 70 meters to the west of Vestman Island (63°20.9' -63°27.7' 

 of northern latitude and 20°19'-20°30.5' of western longitude). The eggs were gathered with a
