FISHES 



[See prints in photograph stand.] 



Market fishes. — Two thousand five-hundred dollars' (^P'SjOOO) worth of 

 fish are sold daily in the Manila markets. A large part of these is bangos 

 {chanos chanos) , which is artificially propagated in large ponds in the 

 vicinity of Manila. Philippine waters abound in excellent food and game 

 fishes. During calm weather they are taken by fishermen in small craft. 

 There are no trawlers operating. 



Sardines. — Such fishes as sardines, anchovies, and herrings exist in the 

 Philippine Islands in large numbers and constitute a potential source of 

 wealth. Nearly all of those caught are consumed fresh or are poorly pre- 

 served with salt. When these fishes are properly canned, the product is 

 equal to the best in the market. Great improvement could be made in 

 the salting of other classes of fishes. There is an abundant local supply of 

 salt. The opportunity for a sardine cannery seems promising. 



Introduced fishes. — The small-mouthed black bass {Micropterus sal- 

 moides) has been successfully introduced from the United States and is 

 established at several points in the Islands.

PRODUCTS FROM MARINE SHELLS 



[See prints in photograph stand.] 



Pearls. — The pearling industry is well established in the southern 

 part of the Philippine Archipelago. Pearls valued at about $500,000 

 (^1,000,000) are exported from Zamboanga each year. 



Pearl shells. — The annual catch of pearl shells is valued at approximately 

 $350,000 (?700,000). 



Button shells. — The top shell (Trochus) and the turban shell (Turbo) 

 are gathered for the manufacture of buttons. They are used locally or 

 exported. 



Window shells. — Window shells are used locally in the place of window
