LIST OF CHIEF LOCALITIES ON CALIFORNIA COAST AND 

 SPECIES FOUND AT EACH 



The following is a list of the more impoi'tant localities in California 

 with tlie species of economic importance fonnd at each. Only species 

 aetualfy nsed and ahnndant enough to he of value are listed. 



Crescent City — The use of clams is strictly local. From Point 

 St. George considerable numbers of r^zor clams are obtained. The 

 rock coclvle is found along the outer beaches. 



Little River — The razor clam is taken in considerable numbers on 

 the sandy beach at the mouth of Little "River, and the locality is there- 

 fore somewhat famous among tourists and local inhabitants. Their 

 commercial utilization is prevented by laws. 



Humboldt Bay — The markets are supi)lied with the AVashington 

 clam {i^axidt)i)>uK) and the soft-shell {My a). The rock cockle (Fapliia) 

 and the gaper (ScMzothaerus) are also abundant enough to be of 

 economic importance but only the former is at present used. The 

 razor clam is found to a limited extent on the outer beaches and used 

 locally. Certain regions of tlic bay receive sewage and precautions 

 .should be observed in the use oF moUusks from these parts. 



Bodega Bay — Th.e soft-shell is ])reseut in (■onsideral)le amount, ami 

 tlie Washington clam is also important. 



Tomales Bay — This is the chief source of rock cockles for the San 

 Francisco markets. The Washington clam and the gaper are also 

 found in Tomales Bay, but are chiefly used locally. The soft-shell is 

 fairly abundant. Oyster beds are also present in the bay. 



San Francisco Bay — Although the Washington clam and the gaper, 

 as well as a number of other species, are present, only the soft-shell 

 i;s marketed. Many localities, because of sewage,' are unsafe ['.ources 

 of food nxollusks. 



Halfmoon Bay — Several species are present, but are used only 

 locally. Borers are found in the reefs and at times some Pismo clams 

 are taken. The Washington clam is present. 



Monterey Bay — Tn the northern half of the bay near Aptos and 

 Watsonville some Pismo c^ams are taken, but the amount is negligible. 

 In Elkhorn Slough the Washington clam, the gaper, the cockle 

 Cardimn and the* rock cockle Paphia are present^ but are only 

 used locally. 



Morro Bay — The beaches north and south of the bay are, with 

 the Pismo-Oceano beach, practically the only source of Pismo clams. 

 The razor clam is also present, but used, if at all, only locally. Within 

 the bay are the gaper (Schizothaerus), the Washington clam, some 

 rock cockles { Paphia) and the geoduck. The soft-shell has been 

 introduced, but has not as yet obtained a foothold; further plantings 

 would be worth while.
