The whiting is much more frequent in our Belts than the haddock, and 
sometimes goes far into the Baltic Sea. But in the summer it seems 
to have regularly disappeared from the Belts. Not till sometime in the 
autumn it appears again, at the same time as other fishes pay their visits. 
In the northern part of the Cattegat we caught rather young whitings (of 
2 different years), often hundreds of them in each haul with an otter-seine, 
the whole summer through; most frequently on 20—30 fathoms. Large 
whitings were taken in the Skager-Rack only. The fry of the year I have 
often seen in the Cattegat, e. g. under jelly-fish, and as far down as the 
Great and the Little Belt. — The whiting is evidently a very migratory 
fish; in its first years it often roams the waters pelagically, entering the 
Cattegat in huge .multitudes, and being carried, accidentally, a shorter or 
longer distance into our other seas. The large, full-grown fish seems, as I 
have said, in the summer to be found on deep water only, outside the Skaw; 
but in November 1900, when I set 600 hooks in the deepest part of the 
Little Belt, from Fænø to Jutland, we caught 9 cod only, but 12 whitings, 
several of which were 15 and 16 inches long. — Ås to the age and growth 
of the whiting, I can say only as Wollebæk (see "Report on Norwegian 
Fishery and Maritime Investigations”, vol. I. 1900. Nr. 1, Chapt V, p. 114) 
that it is difficult to distinguish between the fish of the various years by 
measuring them, although we can easily get the fish in great numbers. 
The different shoals evidently must grow very differently, according as the 
natural conditions are favourable or unfavourable. I must also agree with 
him when he says that it lives in shoals, that it is not attached to the 
bottom when it is young or half-grown, and that it is a very migratory 
fish. When the whiting comes here in the autumn, there is another codfish 
wbich generally comes at the same time, the p»ollack (Gadus pollachius), but 
it comes in much smaller numbers, and I never saw its fry in Denmark. 
In 1900, in October and November, I saw some specimens of this 
fish in the Great as well as in the Little Belt. Interesting is H. Krøyer's 
statement that he once, in May 1834, saw 600—700 pollacks be taken in a 
pound-net at Fredericia. I never saw so many. — The other fish im our 
seas, nearly related to the pollack, the green cod (Gadus virens), does not so 
often, however, go into our smaller seas; nor did I ever see the fry of that 
fish, although I have seen smaller specimens, of c. one foot's length, at 
Frederikshavn. 
Neither the pollack nor the green cod breed in Denmark; they are 
rather rare here, and come as visitors only, with more or less regularity, 
into our seas. In the deepest part of the eastern Cattegat I have in former 
years caught green cod on hooks in the midst of the summer. 
The fry of the green cod, on the other hand, is found in numbers on 
the shores of Norway, west of Lindesnæs, where it may be taken in hundreds 
in every haul with a Danish eel hand-seine. It lives here on low water, 
particularly where the bottom is overgrown with Chorda filum, together with
