cod. No spawning or but, little takes place in greater depths than ca. 100 meters nor in 

 less than ca. 25 meters. 



The greatest production of the fry within the regions investigated occurs on the Britisii 

 Atlantic coasts, in the North Sea and the English Channel. The whiting likewise spawns 

 in rather considerable quantities on the warmest coasts of Iceland (especially the south 

 coast), at the Fœroes, as also to some extent in the northernmost parts of the lîay of 

 Biscay, but on the other hand not on the colder coasts of Iceland (K., N., N. W. coasts), 

 nor probably in the southernmost parts of the Bay of Biscay. 

 The boundaries for the spawning are: 



northern limit: W. & S. Iceland (including these); 



southern limit: northern part of the Bay of Biscay (including this); 



minimum temperature: ca. 5" — 6°; 



maximum temperature: ca. 10°; 



principal spawning time: spring, especially the latter half. 



7. Norway pout (G.Êsmarki Nilss.) 

 Both the northern and southern boundaries lie within the regions investigated. In its 

 requirements as regards depth, temperature and salinity the Norway pout comes nearest 

 to the haddock and its spawning regions agree in the main with those of the latter 

 species. There is but little spawning in more than 200 or less than 50 meters. 



Spawning occurs in greatest extent on the S. and ,S. W. coasts of Iceland and in the 

 northern part of the North Sea. It also spawns in considerable quantities in the northern 

 parts of the British Atlantic coasts and at the FEeroes, but not on the colder coasts of 

 Iceland (E. and N. coasts) nor in the southernmost part of the North Sea, the Channel 

 or Bay of Biscay. (In the Skager Rak and Northern Kattegat the production of the fry 

 does not seem to be very considerable, and there is none in the Southern Kattegat, Belt 

 Sea or Baltic.) 



The boundaries for the spawning are: 



northern limit; off N. W. and S.E. Iceland; 



southern limit: the waters south of Ireland (including these); 



minimum temperature: ca. 6°; 



maximum temperature: ca.9°— 10°; 



principal spawning time: spring, end of winter. 



8. Poor cod {Gadus minutus O.F.Müll.) 



Only the northern boundary lies within the regions investigated. On account of its 

 requirements for high temperatures and shallow depths the poor cod is excluded from 

 spawning over large parts of these regions. 



It is quite absent at Iceland and at the Faeroes but little production takes place. 

 Spawning occurs however on the British Atlantic coasts, in increasing extent from north 

 to south. Within the regions investigated it spawns in greatest quantities in the English 

 Channel, British Atlantic coasts and the Bay of Biscay. In the North Sea and Skager 

 Eak it spawns on a smaller scale and later in the year than on the Atlantic coasts or in 

 the Channel. (In the Kattegat , at least in the southern part , the Belt Sea and Baltic 

 there is no spawning of this species.)
