FISHERY INDUSTRIES OF THE UNITED STATES. Las 
have to attach the buoy line to the moving boat in order to get 
them up. The pots are made of laths and are mostly about 3 feet 
long, 30 to 32 inches wide at the bottom, narrowing to about 12 
inches at the top, and are 12 inches high. They are set singly with 
a buoy line attached to each pot in water varying in depth from 
3 to 20 fathoms. When fishing in deep water, it is often necessary 
to use 40 to 60 pounds of ballast to asingle pot. 
The trammel-net fishery is also quite important. The catch 
consisted entirely of flounders and amounted to 2,182,408 pounds, 
valued at $83,816. Trammel nets are made very much on the plan 
of a gill net, though they have three webs instead of one. A web 
of small-mesh netting is hung between two webs of larger mesh, 
the middle one hanging deeper than the two outside ones, so that 
the fish striking from either side and forcing the small mesh net 
through the larger mesh forms a bag from which it is impossible to 
escape. The two outside webs are 23-inch mesh, No. 12 cotton 
twine, and about 12 feet deep, and the center one is 9-inch mesh, 
No. 9 cotton twine, and about 16 feet deep. One net is 36 to 40 
fathoms long, and a number are usually tied in a string and fished 
as one net, sometimes as many as 20 being used to one string. 
The gill net ranks next in importance. The catch amounted to 
2,260,329 pounds, valued at $68,388. This net is used chiefly for 
fishing barracuda, and over 69 per cent of the total catch consisted 
of that species, the number of pounds being, fresh, 1,362,441, valued 
at $39,957, and salted, 198,000 pounds, valued at $7,900. Sea bass 
and yellowtail also figure quite prominently in the gill-net catch, 
the former amounting to 261,703 pounds, valued at $8,351, and the 
latter to 212,645. pounds, fresh, valued at $3,389, and 55,500 pounds, 
salted, valued at $1,983. 
The quantity of kelp harvested during 1915 was about 1,000 tons, 
valued at $1,000. 
The fishing vessels of 5 tons net or more hailing from San Diego 
County numbered 13, with a total net tonnage of 112 tons and a. 
total value of $34,550. Several of these are from La Playa, located 
on San Diego Bay opposite San Diego, and are fished by Portuguese, 
who fish mostly in Mexican waters and sometimes go several hundred 
miles from their home port. The greater part of their catch is 
salted in the hold of the vessel and consists chiefly of barracuda, 
jewfish, Spanish mackerel, and rockfishes. Other vessels take con- 
siderable quantities of albacore. 
Monterey County.—The products of the fisheries of this county in 
1915 amounted to 14,085,399 pounds, valued at $183,806, and the 
investment was $455,887. e number of persons employed in 
the fisheries and various shore industries was 694. onterey, 
located on Monterey Bay, is the center of the fisheries of the county. 
There are located here 13 wholesale fresh-fish houses and two can- 
neries, where the only sardines canned in the State were canned 
during the year. In addition to these species, one of these houses 
also prepared canned, mild-cured, and salted salmon. One firm 
also was engaged in drying squid, which was mostly for export to 
China. The only real abalone cannery operated in the State dur- 
ing 1915 was located at Point Lobas, about 5 miles south of Mon- 
terey. Monterey Bay is the southern limit of salmon, and the 
major portion of those found there are chinook, a comparatively 
small number of silver salmon also being taken.
