fishbreeder, of Arendal, writes as follows (Morgenbladet, Nr. 532 & 536): 
«What the common way of protecting — some few and insignificant restric- 
tions, while the main-businéss is going on without let or hindrance — leads 
to, is clearly shown by the state of things in Christianiafjord where, in 
spite of the protection, in the course of 20 years, the catch of mackerel, 
flat-fish, cod, and other species of fishes, has dwindled in to a small fraction 
of what it has been”. I shall further state, that they commenced, in 
1892, to place artificially hatched fry of cod in Christianiafjord — so bad 
was the stock. The prohibition against ground-seines seems thus to have 
been rather powerless with respect to advancing the growth of the fry. 
On the other hand, it cannot be denied that there is now, in the zostera- 
fjords near Christiania, an exceedingly rich stock of eels, which nobody 
seems to fish. In a Danish hand-seine, which I tried up there, in 1896, 
under the ægis of Dr. Hjort, we could fish as many eels in every haul as 
in the most "closed” waters of the Limfjord. 
Of late years the fishery conditions of Christianiafjord have now been 
subjected to a renewed and thorough investigation in open nature with 
many different fishing-apparatuses. (See: Fiskeforsøg 1 Norske Fjorde, 1899, 
by Dr. Joh. Hjort, Superintendent of the fishery investigations of the Nor- 
wegian government, and Knut Dahl, M. A, Fellow of Videnskabsselskabet, 
Trondhjem). In this excellent work, which is so rich in new observations 
and new points of view, it is proved that Christiamiafjord is mot at all a 
spawning-water, much less a& spæwning-ground of any importance; the fry lives 
im other places on the shore out by the open sea. We understand therefore 
that the prohibition against ground-seines was without any visible results 
with respect to the growth of the fry of fish in general. If the authorities 
will, and if they can, do something do develop the fishery in Christiania- 
fjord, it must be by something else than prohibitions against ground-seines. 
There is also, of recent date, another still greater experiment in legis- 
lation, which is of great interest, viz. the English prolabition against trawling 
in certain of the larger firths and bays of Scotland, some of which are almost 
to be considered as parts of the North Sea. In 1886 all trawling was pro- 
hibited in these firths. In other words: they were "closed" against all 
trawling. During the following 10 years The Fishery Board for Scotland 
examined the state of the stock of fish at various times of the year, by 
means of a steam-trawler, The Garland. It was expected, of course, that 
this prohibition would produce a rich stock of fish in these waters. But 
Dr. Fulton states that, neither in the closed nor in the open Scotch seas, was 
there, after the lapse of 10 years, any striking increase of the stock of fish 
m general to be seen. Among the flat-fishes, plaice and lemon dabs had 
decreased in number, while common dabs and the long rough dabs had in- 
ereased; and this was the case both m the closed and in the open waters im 
Scotland. 
This result shows then that it is not everywhere sufficient, in order to
