FISHERY INDUSTRIES OF THE UNITED STATES. 73 
PRODUCTS BY APPARATUS. 
The following are the different forms of apparatus used in the 
fisheries of Washington, in the order of their importance, based on 
the value of their catch. The kinds of apparatus, such as dredges, 
tongs, etc., used in taking oysters, clams, and mussels are so varied 
that they are not given any particular ranking on the basis of catch. 
LIines.—Lines are used both in the vessel and shore fisheries, but 
their importance is due mainly to their use in the halibut vessel 
fisheries. The total catch of all species by lines in 1915 amounted 
to 58,923,651 pounds, with a value to the fishermen of $2,446,323. 
Of this amount, halibut contributed 40,590,705 pounds, valued at 
$2,041,279. The total catch by lines in 1904 amounted to only 
15,897,155 pounds, valued at $458,375. 
Trolling.—Trolling has in recent years become one of the important 
fisheries of Washington. It is followed in Neah Bay, Strait of Juan 
de Fuca, and in the Pacific Ocean off the village of Neah Bay, and 
more recently a very large number of boats have been trolling off 
the mouth of the Columbia River. With the exception of fishermen 
from a few towns in Pacific County, however, the latter fishery was 
of no great importancein 1915. In 1916, while no statistics are avail- 
able, it was reliably reported that as many as 1,500 boats from Wash- 
ington and Oregon were engaged in trolling off the Columbia River; 
some of these were sport fishermen, but the greater proportion were 
engaged in commercial fishing. Some of the boats were from as far 
up the river as Vancouver. Many of the gill-net fishermen laid aside 
their nets to troll. 
In 1915 nearly 500 boats were engaged at times in trolling in the 
vicinity of Neah Bay. As in halibut fishing, it is followed on banks, 
very little being done in deep water. The boats alternate between 
fishing in Neah Bay and in the ocean, according to the run of fish. 
If the weather is favorable and fishing good, a boat may remain out 
in the ocean, but this condition is said to have been reversed in 1916. 
The greatest distance resorted to by trollers is off Swiftsure Light- 
ship, 15 miles WNW. from Tatoosh Island. More trolling was done 
on this than on any other ocean bank in 1915. 
The season for trolling is usually from June 15 to September 15, 
and often continues until the last of October or later; but the fall 
gales usually put an end to the fishing, as the boats are too small 
to weather heavy seas. 
The catch consists almost entirely of chinook and silver salmon. 
The former species usually predominates, but in 1915 silver salmon | 
were much more plentiful. Im 1915 probably three-fifths of the catch 
was sold to a nearby cannery and the remainder to buyers repre- 
senting wholesale dealers in Seattle and a few in Tacoma. The fish 
are delivered to the canneries by means of “tenders.’”’ The tenders 
are gasoline boats, each of which tows a large scow. The gasoline 
boat loads first and makes the trip to the cannery while the scow 
is being loaded. The scow is usually anchored in Neah Bay. The 
fish are sold in the round by the fishermen. When sold to a nearby 
cannery the fish are not dressed until landed at the cannery; when 
sold to distant canneries they are dressed on the cannery scows as 
they are brought in. In 1916 a canning firm at Anacortes had a 
scow anchored in Neah Bay fitted up with an “iron chink,” or dress-
