By far the largest quantities of deep-water prawns in this 
area have been caught in the Bundefjord at from 30—80 fathoms 
as well as in the basin between Steilene—Slemmestad—Bjerkøen 
and further out along both sides of the fiord, between Haaøen and 
Graaøen, and between Koholmen and the mainland, for the most 
part at å depth of 40—60 fathoms. In this locality some millions 
of Pandalus are annually caught. 
Christiania Fiord. Outside Drøbak. Large portions of 
the outer basin of this fiord contain immense quantities of Pan- 
dalus. Between Horten and Rødtangen, Holmestrand and Soon 
there are large grounds, continuous with each other for the most 
part and about 60—100 fathoms deep, where prawns have now been 
trawled for several years. Out beyond Horten they are generally 
found in greatest abundance to the north-west of Rauø and between 
this island and Onsølandet, at Missingerne, between Struten and 
Torgauten, east of Bolærne and Fuglehuk; though the most pro- 
ductive grounds are out beyond Hvalerøerne, in Alendybet, and 
between Kirkeøen and the Swedish coast, in Sækken. In this last 
loeality Pandalus has been met with in such dense masses that the 
trawl brought up nearly 300 liters in the course of å single hour. 
Caleulating large full-erown Pandalus prawns at about eighty to 
the liter, this would mean 24000 prawns in the said haul at the 
very least. 
Searvi Frord and 
4. Brevik Fiord. If we except the Drammen fiord these 
were the two first fiords in this country where Pandalus was shown 
to oceur in abundance (1898). For investigations into the occur- 
rence of Pandalus in these fiords the reader is referred to å book 
by J. Hsort and K. Daut: ,Fiskeforsøg i norske fjorde*, (Kris- 
tiania, 1899), and *Fishing Experiments in Norwegian Fiords” 
(Report on Norwegian Fishery and Marine Investigations, Vol. 1 
1900, no. 1).
