the San Joaquin River at or near Jersey Landing, in Contra Costa County, and at 
Black Diamond, near its mouth, in the same county; the others were set in the Sac- 
ramento River, in the vicinity of the city of the same name and elsewhere along the 
course of the stream. The San Joaquin River fishermen represent three countries — 
Greece, Italy, and the United States — although the Greeks and one Italian have 
become citizens of this country; in the Sacramento River the fishermen are all China- 
men. Sailboats are used to lift the nets in the San Joaquin River and rowboats in 
the Sacramento River. 
The fishes taken in the fyke nets in the Sacramento and San Joaquin rivers 
represent a variety of species, among which the following may be mentioned, the 
common names given being those used by the fishermen: Carp ( Gyprinus carpio ), 
introduced; catfish (Ameiurus nebulosus ), introduced; chub ( Myloclieilus caurinus ) ; 
hardhead (? Mylopliarodon conocephalus) ; perch ( Archoplites interruptus and Hystero- 
carpus trasM) ; split-tail (. Pogonichthys macrolepidotus). In addition to the foregoing, the 
following fish were, a number of years ago, reported to be taken in fyke nets in the 
Sacramento River: Sacramento pik e (Ptychocheilus oregonensis and P. harfordi)-, in 
recent years these may have been returned under the name “ chub,” which is more 
appropriate than “pike;” sucker ( Catostomus occidentalis) ; sturgeon (Acipenser trans- 
montanus ); herring ( '? Clupea mirabilis). 
The yield of the California fyke nets is relatively large, the average per net being 
much greater than in most of the other States. In the San Joaquin Rfver the average 
catch per net is 1,893 pounds, valued at $55; in the Sacramento it is 5,824 pounds, 
worth $150. It is interesting to observe that at the present time about three-fourths 
of the output of the State consist of two introduced fish, the carp and the catfish, 
which make up the entire catch in the San Joaquin. Twelve men engaged in this 
fishery in Contra Costa County and 20 in Sacramento County. They used 16 boats, 
valued at $1,050, of which 6, worth $900, were used in the former county. The 49 
nets operated had a value of $980; 24 of these, worth $480, were set in Contra Costa 
County. The aggregate catch amounted to 194,647 pounds, for which the fishermen 
received $5,116. The extent to which the different species are represented in each 
county is as follows :
