constituted the bulk of the catch. The Sacramento River, together 
with San Pablo and Suisun Bays, furnished the bulk of the gill-net 
catch of the State. While drift gill nets were used in asmall way as 
far up the Sacramento River as Corning, Tehama County, they ceased 
to be important as an apparatus above Verona in Sutter County. The 
length of drift gill nets varies from those measuring 170 yards each, 
used for chinook salmon along the upper portion of the river, to 
those measuring 450 yards each, used for shad near the mouth of the 
river. ‘The nets used for chinook salmon and striped bass near the 
mouth of the river average about 385 and 420 yards, respectively. 
In Suisun and San Pablo Bays, nets as long as 800 yards are used for 
striped bass, shad, and chinook salmon. ‘Those for chinook salmon 
are from 40 to 45 meshes deep; those for striped bass from 30 to 65 
meshes, and those for shad from 60 to 65 meshes. ‘The size of mesh 
varies in the salmon net from 74 inches to 93 inches; in the striped- 
bass net it is commonly about 54 inches; and in the shad net from 
54 to 64 inches, but more often of the latter size. 
The bulk of the gill netting credited to Del Monte County was done 
in the Klamath River, from its mouth to a point 6 miles above. A . 
cannery at Requa utilizes most of the catch. The chinook salmon 
run from March 1 to September 1, with a few in October, while the 
silver salmon run from September 20 to the last week in October. 
The nets on this river average 200 yards in length and 30 to 35 meshes 
deep. ‘The mesh varies from 64 to 9 inches, but more of the smaller 
size are used. 
Gill nets constitute the most valuable apparatus used in Humboldt 
County, a very large percentage of the catch being taken with them. 
The Eel River is the only stream of any importance in the county. 
Practically all of the fishing in this river is done between the mouth 
and 34 miles above. The drift gill nets used on the river average 
about 150 yards in length, and from 28 to 32 meshes deep. The 
mesh for chinook is 94 to 93 inches, while that for silver salmon and 
steelhead is 64 inches. The fishing is done from October 7 to Decem- 
ber 7. The same fishermen in some instances fish in both the Kla- 
math and Kel Rivers. 
Paranzella nets—Paranzella or trawl nets are used both in the 
vessel and shore fisheries of California, but the catch in the former 
is much more important. The fishing is confined to the Pacific Ocean 
from San Francisco, Santa Cruz, and Los Angeles Counties, that from 
the first-named county being much the more important. In 1915 
the total catch amounted to 9,707,373 pounds, valued at $193,368, 
as compared with 5,637,561 pounds, valued at $104,602, in 1904. 
Many species are taken, but sole and flounders constitute more than 
96 per cent of the catch. 
The paranzella, a somewhat primitive style of net, was intro- 
duced in California by Italian fishermen in 1877. It consists of a 
flat, triangular bag of webbing, doubtless developed from a beach 
seine or bag net, with a wide but low mouth. The net rapidly nar- 
rows from the wide mouth to the cod end of the bag, hbk is so 
arranged that it can be unlaced to discharge the catch when it is 
hoisted aboard the boat. The nets are constructed of heavy cotton 
twine. The forward part of the bag is of about 4-inch mesh, the 
middle part still smaller, and the cod end of much heavier twine,
