The lem OU Dab (Plenronectes microcephalits), wliich is kuowu as a growii-up 

 fisli only, and iii three specimeus of 41/4 — 41/2 iuch. *). 



The Megrim (Arnoglossus laterna), a little flat-fish, which iu mature state is ouly 

 5 — 6 inches long. It is very characteristic of the clay-mixed sand. It seems 

 to occur particularly l'requently on 15 — 20 fathoms N. and E. of Læsø. 

 Next to the flat-fishes the cod-fishes are strougly represented, and 



occur so commonly that several of them, in a certaiu way, may be classed 



among the statiouary fishes of this region: 



The commou Cod, the various age-groups; but, as in the zostera-belt, there 

 seem to be no piaces liere either, where the fi-y of the year and the oue 

 year old fish occur in great numbers. 



The Whitiug, most frequently young specimens, not over 10 — 12 inches long. 

 The fry (the 0-group) is caught pretty commonly, particularly in plank- 

 ton-bags, as the young fish (Y2 — l'/a inch) seek refuge under jelly-fish 

 {Cyanea capillata). 



The Haddock [Gadtis æglefinus) is also commonly met with, but particularly 

 in the deeper parts of the belt. It seems more than the whitiug to be 

 attached to the bottom; its food consists almost exclusively of animals 

 that live on the bottom, chiefly serpent-stars (e. g. Amphhira filiformis), 

 while the wliiting particularly feeds on various small fish (small herrings 

 and sprats) which, partly at any rate, live in other strata of the water. 



The Hake [Merlucius smiridus). Young specimens live liere, possibly, at all 

 times of the year, while the large ones seem to enter this proportionally 

 low water in some of the summer months only (May, June, and July), 

 probably in order to breed. In July- August its eggs, strongly pigmented 

 with yellow, are very common in the surface-water of the sea. That the 

 large hakes (of 20 — 30 Ibs. or more) get in here only at the said time 

 of the year agrees with the statements of the steam-trawlers. 



Gadus Esmarlm and Gadns minutus, which are seen here now and then, must, 

 on the other hånd, be looked upon as quite accidental visitors, occasion- 

 ally getting in here from the Skager Rack. It seems, as if only a single 

 age-group occurs; probably, therefore, they do not breed here. 

 Of other forms of fishes which almost constantly occur here, we may still 



mention : 





on 16 fathom.s, cmp. journal-number 119; but tlieir number has been so small that it is 

 scarcely possible to decide, whether they have formed a particular age-group (the 0-group) 

 or been specimens onlv of the I-gioup which have been stunted in their growth.
