 4- Qadus pollachius, L., Pollack 



(see Chart fig. i6) 



I. Atlantic Ocean 



The early stages of Gadtts pollachius were found from the north coast of Scotland, 

 along the west coast of Great Britain, in the Channel and in the Bay of Biscay as far 

 as to the southernmost point investigated, S. Sebastian. The spawning shows a tendency 

 to increase from Shetland to Ireland and occurs everywhere in the neighbourhood of the 

 land and on the Atlantic coast in great quantities during the spring months. The south- 

 ern boundary of the spawning region thus lies beyond the region investigated. 



II. Norwegian Sea 



(a) On the Norwegian coast of the Norwegian Sea this species spawns at 

 any rate in some of the fjords and occurs up to Hammerfest. The spawning time is in 

 summer but has not yet been closely investigated. 



(b) The species occurs at the Faeroes but only in small quantities and in any case 

 spawns there but little. 



(c) At Iceland, unknown. 



III. North Sea 



In the North Sea a few small larvae were found at some of the central stations, as 

 also in the Skager Rak near the Skaw and along the Norwegian Skager Rak and North 

 Sea coasts. All these catches were made in the beginning of summer and contained but 

 few specimens. Ripe specimens appear on the market at Bergen in summer. 



5. Gadus asglefinus, L., Haddock 



{see Chart fig. 14) 



I. North Sea 



The spawning places in the North Sea are limited to the region between the 40 M. and 

 the 200 M. lines. Neither the Danish, German, Dutch nor Norwegian investigations could 

 find more than single eggs or larvae near to the coast, between the land and the 40 M. 

 curve. It was only in the deeper parts between the Dogger and the coastal banks, as 

 also in the deep part of the North Sea north of the Dogger that any large catches were 

 made. These seem to increase on the northern slope of the North Sea Bank, so that 

 the most spawning occurs apparently above depths from 60 to 150 M. On the Dogger there 

 is but little spawning, but a great deal on the Ling Bank and the Great Fisher Bank. 



In the Skager Rak the spawn was found in rich abundance on the Jutland Bank, 

 mostly on its slope towards the deep basin of the Skager Rak. Spawning also takes 

 place on the Norwegian Skager Rak and North Sea coasts, but not in the fjords. We 

 may say, on the whole, that the spawning time of the haddock like that of the cod falls 

 in the period from January to May, with the maximum in March. 



II. Norwegian Sea 



(a) On the Norwegian coast of the Norwegian Sea there is everywhere but 

 little spawning in comparison with the North Sea. This is already the case on the
