126 FISHERY INDUSTRIES OF THE UNITED STATES. 
sailboats, valued at $5,000; and 7 house boats, worth $1,400. A 
branch of a firm in Pittsburg salted large quantities of shad here. 
Solano County.—There are several important fishing localities 
in this county, the most important of which is Rio Vista. The greater 
part of the fishing is done in the Sacramento River, but a consider- 
able amount is also done in San Pablo and Suisun Bays and San 
Joaquin River. The catch consists mainly of chinook salmon and 
striped bass. Large quantities of shad are taken, but the price is 
too low to afford much profit. Gillnets are the only form of apparatus 
used in the county. One cannery at Benicia and a mild-curin 
establishment at South Vallejo utilized large quantities of chinoo 
salmon. Most of the catch, however, as in Contra Costa County, 
was handled by local buy boats working on commission for San Fran- 
cisco firms. | 
Marin County.—Considering the extent of its fisheries as compared 
with some of the more important counties, the variety of fishery 
products in this county is rather noticeable. The greater part of the 
fishing is done in Tomales Bay, but some of the fishermen along that 
bay also fish in the ocean. Many kinds of apparatus are used, but 
the most important forms are seines and gill nets. The leading 
species taken with seines are surf fish, herring, and perch, and with gill 
nets sea bass, smelt, and striped bass. Considerable quantities of 
clams are taken in‘'Tomales Bay, but the industry is far less impor- 
tant than that of the oyster, which has been developing to some extent 
during the past few years through private planting. The cultivation 
of clams on private beds has also been undertaken recently. As 
Tomales Bay is comparatively free from impurities, it is thought that 
both the oyster and clam maasinies should improve with attention. 
A few men were engaged for a short time in 1915 in taking abalone, 
the resultant products consisting of $450 worth of shells, $158 worth 
of abalone meat, and $40 worth of pearls. 
Sausalito is situated on Richardson Bay, but its leading fishery in- 
dustry is that for crabs, conducted in the Pacific Ocean. The output 
in 1915 amounted to 163,800 pounds, valued at $16,134. 
San Joaquin County.—The total output of the fisheries of this > 
county in 1915 amounted to 1,330,674 pounds, valued at $44,236, _ 
showing an increase since 1904 of 803,853 pounds in quantity and 
$21,960 in value. Catfish was the leading species, two-thirds of the 
State’s catch being credited to this county. They were taken in the 
San Joaquin River in fyke nets and seines, but mainly in the former. 
Next in importance to the catfish is the chinook salmon. Shad 
exceed all other species in abundance, but its importance is much 
lessened by the low price received by the fishermen. More than one 
and a quarter million pounds of this species were salted at different 
points in the county during the year, many of the fish coming from 
points outside of the county. Of the firms engaged in salting, one 
was American and the other two Chinese. Practically all of the salted 
shad were shipped to China. Stockton is the center of the wholesale 
trade of the-county. 
Humboldt County.—The output of the fisheries of this county in 
1915 amounted to 829,630 pounds, valued at $32,796, more than one-. 
half of the value being credited to chinooksalmon. Among other spe- 
cies worthy of mention are silver salmon, flounders, smelt, steelhead 
trout, soft clams,and crabs. This county borders on the Pacific Ocean,
