OF THE GRIMSBY TRAWL FISHERY. 343 
PART I. 
Cuap. I.—Tae Norra Sea Fisuerizs. 
Iw addition to trawling, with which we are here almost exclusively 
concerned, the North Sea furnishes scope to a number of other 
branches of the fishing industry. Of these, line-fishing and drift- 
netting are the most important; oyster-dredging is a considerable 
deep-sea industry, and whelking may almost be included in the same 
category. The remaining branches, such as crabbing, lobster-potting, 
shrimping, and seining, are carried on in the more or less immediate 
neighbourhood of the coast. We are concerned with none of these 
except in so far as they may be shown to affect, or be affected by, 
trawling. 
The North Sea fishery, if the apparent paradox may be pardoned, 
is by no means confined to the North Sea itself, since it is impos- 
sible to leave out of consideration the fishing operations of vessels 
belonging to, and regularly landing their fish at, North Sea ports. 
Many of these, chiefly liners, derive the bulk of their fish from 
grounds which lie altogether outside the limits of the North Sea. 
The Orkney, Shetland, and FarGde Islands, Rockall and Iceland, 
are all extensively worked by North Sea codmen, and the last-named 
district to some extent by trawlers also ; the fish from these grounds 
pass through the North Sea markets, and are not discriminated in 
any Government returns from those caught in the North Sea. 
A certain number of boats belonging to North Sea ports are 
engaged in fishing operations on the west coast of England and 
elsewhere, but, for the time being, they land their fish on the west 
coast, and so may be considered to cease to belong to the North Sea 
fishery. Drift-net boats—at least those which are worked the whole 
year round—may be said to be nomadic, making their headquarters 
in whatever district the fish may be at the different times of the 
year. 
Fisheries of various kinds are carried on all along the east coast 
of Scotland, and these must of course be held to belong to the 
North Sea group. The bulk of the line-fishing, however, is done 
close to the ports to which the vessels belong ; and even the trawlers,
