Distribution of Large Larvae 



Large larvae of the summer herring --20 to 25 mm. in length-- were found by Schmidt at 

 the end of July and beginning of August 1904 off the south and west coasts of Iceland. In July, larvae 

 from 10 to 15 mm. in length were caught by Schmidt to the west of Cape Dircholei (63°23'N, 19°25' 

 W). In August, he found large larvae to the west of Westmannaeyjar Island. He discovered the 

 largest number of larvae in August further north, at tlie entrance to Breida Bay (65°15'N, 24 45'W) 

 and to the west of Cape Reykjanes (63°45'N, 23°45'W). At the same time, he made about 40 sta- 

 tions along the eastern and north-eastern shores, but no larvae were discovered in these regions. 



o 



A. (sic.) Taning (20, 21, 22, 23) found large larvae of summer herring in the region from 



Stoksnes along the south, south-western and western coasts to Cape Isa Fjord. Off the south- 

 eastern coast, larvae were found in 1933 and 1950, the rest in earlier years. In 1939, he found 

 them to the east of Westmannaeyjar Island and Faxa and Breida Bays. Lastly, in 1946, he found 

 larvae in September in the same regions and to the north-wesfof Isa Fjord (Figure 3). Observa- 

 tions of the change in size of the larvae in conjunction with the times at which they were caught 

 give an idea of their growth. In July and early August, larvae about 10 mm. in length appear (un- 

 doubtedly herring of the summer race), in the second half of August their length increases to 15-20 

 mm. In September, the average length reaches 18 mm.
