young, Y2 — 2 cm., in a 40 miuutes haiil in intermediate layers with the youug- 

 fish trawl. 



Both in April and Jnne \ve were stationed near the boundarj' towards the 

 Kattegat, and as we never found the haddock young in the Kattegat in these 

 mouths the limit to their distribution must have been verj' sharp. 



Nor did we find the haddock 3'ouug within the Slcaw later in the year. 

 Like the cod, it must have been for the most part in the bottoui-stage, wheu the 

 June storms caused the great invasion of whitiug. 



AVe took a pelagic haddock young in the Skager Rak even at the end of 

 June, but it was 7 cm. long (the haul is mentioned in detail under whiting). It 

 was the only haddock young we took in July, though we fished much more in 

 the Skager Rak in this month than in April and June, and though we made both 

 intermediate and bottom liauls. We obtained the whiting young in quantities, but 

 no haddock young apart from the one mentioned. Larger haddock of 22 — 37 cm. 

 were obtained however in a bottom haul in ca. 60 fm. water. The same must 

 have happened to the haddock young therefore as to the cod young. During 

 (hvelopment Oiey have been steadih/ carried further and further airmj from the Danish 

 ivaters. Haddock eggs were detected in the Kattegat, the tiny fry in quantities in 

 the Skager Rak near the bouudary to the Kattegat; the larger fry were found in 

 the Skager Rak but only a single specimen. 



Wheu the stock of fish in the Skager Rak and northeru Kattegat was 

 investigated in 1897 — 98 (see Biol. Stat. Beretn. IX), not a few haddock young 

 were taken in July both in the Skager Rak and northernmost part of the Kattegat, 

 north of Læsø; they were ca. 3 — 4 inches (ca. 8 — 11 cm.) in length. 



Larger haddock of ca. 40 cm. and above are taken by the fishermen now 

 and then in the autumn in tlie Great Belt. 



Norway Pont, Gadus esmarkii. 



We found the pelagic young of the Norway pout in the Skager Rak both 

 on April 28th and June Ist (Tab. 1), but oulj' in small uumbers; in April we took 

 three, all small, in June one, ca. 1 cm. 



We also found the young of the Norway pout in the Kattegat in June: 



D. 3—6—04. E. from the Flounder Groun.l, 40 fm. (Tab. 1, Kattegat). Young-fish 

 trawl on blocks on the bottom, 15 minutes: o Norway pout, ca. IV2 cm. 



I). 6—6—04. He'sselø in W. N. W., 6 miles, 10 fm. (Tab. 1, Kattegat). Young fish trawl 

 — ca. 9 fm., 30 minutes: 1 Noricay pout young, many other younfi of fishes. 



In 1903 A. C. Johansen took three pelagic young of the Norway pout in 

 the Skager Rak on April 29th. 



We also took a pelagic young specimen of the Norway pout in 1903, ca. 

 1 cm., in the Great Belt on the 18th of August (see under whiting). 



The pelagic young of the Norway pout have therefore been found in April, 

 June and August; in April only in the Skager Rak, in June also in the Kattegat 

 and in August even in the Great Belt. The pelagic young of the Norway pout like 

 those of the whiting i)enetrate further into the Danish wateis during development.
