II. On Other Codfishes in our Seas. 
Besides the common cod, we have as above mentioned a number 
of other codfishes in our seas, whose migrations and biology it may 
be of interest here to compare more closely to what I have stated above. 
The haddock is so rare in the Belts that, during the three years in which 
the investigations have been carried on by steamer from April to November, 
both included, I have caught, and seen at the fishermen's, in all, only one 
single specimen. The Little Belt fishermen mention it as "the light cod 
with a black spot on each side”, but they do not know its name. It 
appears in the Little Belt in certain winters only, consequently as a veri- 
tably migratory fish, which is not at all at home in the Sound or the Belts. 
The haddock is said to have been frequent in the Sound in certain 
years, many years ago; but now there has not for many years been any 
fishery for it there. In the Issefjord, where no haddock is found now, there 
must in the stone age have been many of them; for in the kitehen-middens 
at Sølager a great many bones of haddocks are found among the other 
remains of meals, and the people of the stone age must no doubt have 
caught the fish near the place where they have eat them, consequently in 
the Issefjord. 
In the Cattegat, on the other hand, the haddock is found in the deeper 
regions on the soft bottom. It is most frequent in the winter half-year. 
Its fry is generally not found in the Cattegat in large numbers; only a few 
specimens have been taken in the northmost Cattegat on a depth of 20—30 
fathoms, and in the Skager-Rack on 70 fathoms, as also a few pelagic ones. 
For the present time at least, the haddock then occurs in the 
Cattegat as a visitor only, and it does not breed there. It prefers the deep 
water — much more so than the cod — from which reason it does not 
enter our fjords at all. This holds good also of its fry.
