COLONIAL KISHERIES 



1. The tlshorles of Japanese colonies prior to World 'Aar II conslsteil of those of Korea, Xarafuto, 

 Fom.osa, the Uan-iated Islands, and the Kwant-mg i^oninaula (Tahl- 11 and Flpire 6). Production data for the 

 colonics are incomnlete. 



2, Korea was much the largest colonial producer, averaging l,li6l,000 tons annually in ig'l-JS. The 

 bulV or this catch consisted of -ord-ines, inost of which w?re converted into oil and :pcal. The Karafuto pro- 

 duction averaged lUi.OCO tons, the Formooan nrod-jctinn 88,750 tons, and the Kwantnng Peninsula 5f,925 tons 

 for 1951-}?!. The conmerclal catch of the Mandated Islands during 195^-39 averaged about 25,000 tons, most 

 of which was bonito dried and processed as bonito sticks (katsuobushi). 



}. Although the colonial fisheries contributed to the nrotiuction fror. the Japanese Empire, much of 

 their yield did not suooly Japan Proper. Korea was th- largest colonial supplier, exporting about U2 percent 

 of its production to Janan 15/. A considerable part of the Forrnosan catch was consumed domestically or sent 

 to southern China, and much of the Kwantung catch was consumed in Manchuria. Although most of the catch of 

 the Mandated Islands was sent to Janan, In exchange Japan supplied the Uandat^a Islands with canned and 

 salted fish. 



15/ Extxjrts were largely sardine oi'l and meal. 

 ie, fish PRight as landed. 



This percentage iras calculated in terms of raw materials.
