!Eh® breeding of ornamental goldfish (a relative of the carp) 
produced annually 60 million fish valued at ¥ 531,000 - ¥ 667,000. The 
industry centered largely in Tokyo, Nara and Aichi prefectures.

All except ma-sizimi were reared along shallow sea coasts; it was produced 
in lakes, rivers and swamps in all parts of Japan except Hokkaido. 
Of these asari and hamaguri (clam and "clam like”) were reared 
most extensively, especially asari of which more than 60,000 metric tons 
were raised in 1937 (Table 15). They were reared in shallow coastal waters, 
especially in places where the bottom was sandy or slimy and wnere there 
was some admixture of fresh water from rivers with the sea water. Among 
the most important producing areas was Tokyo Bay where 1,200 fishermen 
were engaged in this industry. 
Hotate-gai (scallops) were reared most extensively along the 
eastern coast of Hokkaido by a procedure similar to that used for oysters. 
The spats which are free-swimming were collected on old shells suspended 
in the water of calm bays and later the scallops were transferred to open 
coastal waters where tmey continued their development.
