to the south in such great densityo There is a possibility that in 

 the North Sea two cod populations appearo One to the south, of which 

 the females become ripe at 24 centimeters, and one in the north 

 where the females become ripe only when they have reached a length 

 of 60 centimeters I the southern group having been heavily overfished 

 and the northern group very little or not at alio There is no 

 certainty regarding this question since very little has been done 

 to investigate the cod in the southern part of the North Seae 



Howeverj to aid the conservation regulations for the haddock it 

 is necessary to set the same minimum size for cod, since both species 

 can be expected on the same grounds o Commercially there are no 

 objections against thiSj since before the war very little cod below 

 29 oontimeters was looked upon as marketable o

This species has a low value, except during the war years, 

 and protection is therefore not necessary for its own sakeo Nor is 

 it necessary for the protection of the haddock since the whiting 

 usually is found on more southerly grounds <, However, whiting 

 appe%r also on the young plaice grounds and in this respect every- 

 thing that may lead to more intensive fishing has to be avoided© 



Large quantities of whiting begin to appear along the coast 

 in autumno Catches of whiting might make the fishing on coastal 

 grounds profitable again, but the catches are too irregular to cause 

 many ships to fish for this species only in the coastal arease The 

 younger plaice, moreover, have started their migration to deeper 

 water and the few ships which fish for whiting will not do very 

 much damageo Therefore, we do not consider it necessary to prevent 

 fishing for whiting between 20 and 29 centimeters© 



Smaller whiting appear on the coastal grounds in the early 

 summer and during the summer when most of the young plaice are still 

 there© During this period the fishing for v;hiting must be made 

 uneconomical and it is therefore desirable to place the minimxmi size 

 for whiting at 20 centimeters©

These species are not important enough for a separate discussion© 

 The size set by the London Conference of 1937 oe.n be accepted without 

 objection© For the three species the proposed minimum size was 23 

 centimeters ©

The minimum size for heek will have to be set at 29 centimeters 

 to help in the protection of the young haddock© The size proposed 

 in London was 30 centimeters© We can accept this size without objection©
