1. Separate Btatiat.lca for aquicult.ure date from 1912 when aoout 1(5. f^ tons of fish, shellfish, ^nd 

 seaweed wore produced. Aqulcult'ire nroductlon gradually increased, and during 1951-5'^ <t averaged ahout 

 lliO,000 jDns annually (Table ?). The main products are carp, eel, nrnlleo, and trout, oysters, clams, and

2. Aoulcrlture oroduction, uniiKe the other fisher' es. r^eihea Its peav during World War II uhon a 

 wartime shortage of food and the curtailaent of sci?e sea fisheries brought about a concertpd effort by th«» 

 Japanese Govemsient to increase fish culture. "About 250,000 tons were produced jy this means in 19lii. In 

 late TqIiIi and 19U5> however, despite continued govemirent encouragement, aqulciilture production declined 

 because of a shortage of the food used in feeding fish raised in nonds and rice fields 11/. 



11/ The n-.ain foods used for fish in ponds ann rice fields are sanagi (silkworm chrysalises) and nuka 

 (rice husks). During the latter psrt of the war the silV industry was cui tailed by diverting mul- 

 berry land to rice fields, thus red'iclng the supply of silkworm chrysalises. Sice husks were eaten 

 by the people and to some degree even siU-Trorm chrysalises, wnlch arc rich in B vitamins, ware also 

 eaten.
