Abstract
1) Bonito south sea fishering by the Okinawa people has been remarkably developed for these years. Blessed with abundant source of bonitos, they are getting much of a large quantities of them at Bismark Sea, Solomon Sea and Coral Sea as their fishing ground.
2) It is the big fisherng companies at the Main Island which controlled the Okinawa's south sea bonito fishery. They made contact with local governments, got the fishing right there and charted the Okinawa bonito ships for it. They carry on buying business of bonito catch at such bases as Madung (New Guinea), Kavieng (New Foundland), Rabaul (New Britain) and Guadalcanal.
3) Bonito price is unreasonablly low fixed at these fishing bases. Since the economic position of the Okinawa fishering enterprises is extremely inferior to that of the colossal Mainland fishery companies, the market price is onesidedly settled by the latter.
4) The place where the bonito fishering is the most developed are Islands of Irabu and Ikema in the Miyako Archipelago. Fishers working to the south sea from these islands are over 700 persons in 1971. It has caused extreme decline of the coastal fishery of the village itself.
