FISHES OF SACRAMENTO-SAN JOAQUIN BASIN. abs | 
INTRODUCED SPECIES. 
A review of the history and results of the attempts to acclimatize fish and other 
water animals in the Pacific States is given by Dr. H. M. Smith in the Bulletin of 
the U.S. Fish Commission, vol. xv, 1895, p. 379-472. Thirty species are mentioned 
in this report. The following is a list of those planted in our territory:

Fortunately only a few of the 24 species mentioned above have obtained a foot- 
hold in California waters. The following, and possibly others, are now a portion of 
the fish fauna of the state. 
Ameiurus catus (Linneus). Common Catfish. 
Introduced from eastern waters and now exceedingly abundant in the lower rivers and in brackish 
water. Distinguished from A. nebulosus by the deeply emarginate caudal fin. Observed in the Sacra- 
mento River at Red Bluff, Jacinto, Knights Landing, mouth of Feather River, Sacramento, Walnut 
Grove, Ryde, Rio Vista, and Benicia, also in the San Joaquin at Antioch, and in Carquinez Straits. 
Reported by Jordan & Gilbert from Clear Lake. 
Ameiurus nebulosus (Le Sueur). Bullhead Catfish. 
Introduced into the streams of the state along with A. catus. Distinguished by the truncate or 
rounded caudal fin. 
Taken in Sacramento River at Knights Landing, Arcade Creek at Arcade, South Fork Dry Creek 
near Grass Valley, Carquinez Straits at Benicia, and in China Slough and Kings River near Centerville. 
Reported by Jordan & Gilbert from Clear Lake. In the lower Sacramento much less common than 
Ameiurus catus. 
Cyprinus carpio (Linnzeus). Carp. 
A Chinese fish introduced into California from Germany, Japan, and the eastern states. For a his- 
tory of the carp in California see ‘‘A review of the history and results of the attempts to acclimatize fish 
and other water animals in the Pacific States,’ by Hugh M. Smith, Bulletin U. 8. Fish Commission, 
vol. xv, 1895, p. 379-472. 
The carp is now abundant in the quiet waters throughout the lower portion of the basin, even enier- 
ing brackish water. It is a sluggish fish, little esteemed as food, and an important source of food for cor- 
morants and striped bass. Said to be less common in the Sacramento River between Red Bluff and 
Redding than it was a few years ago.
