similar to tliat of the cod, so that referring to what has been said regarding the latter 

 (p. 20), I need add but little here. During the first voyage in April no pelagic fry of the 

 haddock were as yet found, but on the second (eastwards round the island) at the end of 

 May, it was found that they were distributed along the whole south coast and the greater 

 part of the west coast, whilst they were absent on the east and north coasts. On the 

 west coast in the middle of June they were not distributed quite so far to the north as 

 the cod fry, the most northerly station where they were taken being St. 140 off Dyre 

 Fjord. On the third voyage in the latter half of July (see Chart X, 2 and for 1905 

 Chart X, 4), thus ca. 7 weeks later, they had reached to Cape Langanes (north-east point 

 of Iceland), and were thus distributed along the whole north coast, but were still absent 

 from the east coast. Lastly, on the fourth voyage in the middle of August, i. e. ca. 3 weeks 

 later, they were also found along the northern part of the east coast. We see therefore 

 that the pelagic haddock fry are involved during their development in quite the same cir- 

 culation movement round the island as the cod fry (in the direction of the hands of a 

 watch). From the south and west coasts where they are spawned, they are carried 

 northwards along the west coast, then eastwards along the north coast and finally south- 

 wards along the east coast with the great body of water (Irminger Current), by means of 

 which warm and salt Atlantic water replaces in summer and autumn the fresher and 

 colder water along the northern and eastern coasts. In the whole of this movement there 

 is no other difference between the cod and haddock fry than that the former is always in 

 advance of the latter, owing to the somewhat earlier spawning of the cod, as can be seen 

 from the various charts. Thus the haddock fry like the cod fry are distributed round all 

 the coasts of Iceland, in spite of the fact that the species only reproduces on the south 

 and west coasts owing to the peculiar hydrographical conditions. The haddock is an ex- 

 tremely common fish at Iceland and in agreement with this we find that several of our 

 pelagic hauls have taken a very large number of specimens, e. g. 506, 372, 288, 236 etc. 

 per half hour's haul. 



2. The Faeroes 



The eggs of the haddock have been found everywhere in quantities round about 

 the Faeroes in the month of May (1903, 1904, 1905) at temperatures varying from ca. 6V2 

 — 8°'. The tiny pelagic fry were also taken in this month at various places, yet not in 

 very large numbers (owing to the fact that this month is still in the middle of the 

 spawning time of the haddock, which according to our investigations falls mainly in April 

 and May). In June no investigations were made there, but in July large pelagic fry of 

 the haddock were still found in quantities at the Faeroes; thus we have taken up to 350 

 specimens (length: 2 — 5 cm. most at 3 — 3^/ä cm.) in a haul of half an hour. 



3. British Isles 



Concerning the spawning time at Scotland (east coast probably) McIntosh and 

 Masterman say (1897, 1. c. p. 245), that "the majority of the females appear to spawn from 

 mid-March to mid-April" \ from which we see that it is not a little earlier than at Ice- 

 land, as is the case indeed with so many other species. 



In the beginning of May 1905, St. 19, 20 and 21, we took the eggs of the haddock 



1 All the mature haddock females taken on May 11th 1904 on the Faeroe Bank by means of lines 

 had running spawn (St. 77).
