It is understandable in the name of common sense that marine farming which is the enterprise of latter-day character inevitably exerts some influence upon long established fishing industries. The main theme of this paper is to analyes the relationship between pearl culture and other kinds of industry in the seaside villages of Ago Bay, located in the southern part of the Shima Peninsula.It is needless to say that area in question is blessed with various conditions such as configuration of the ground, the depth of water, the temperature of water, and salinity, which are considered before everything else as the prime condition for location of the unique industry, pearl culture. Upon analysing the area minutely, it can be proved that there is hardly any difference in these natural conditions over the whole surface of the Bay; especially since people have come to use different fishing-grounds in the winter and summer seasons, any regional difference in natural conditions at the Bay is no longer recognized.Notwithstanding, there must be some facter other than natural conditions working upon the fact there is a considerable difference in the growth of marine farming between the villages situated at the inner part of the Bay such as Shimmei, Takegami and Ugata and those in the southern part such as Fuseda, Katada and Funakoshi; and that center of pelagic fishery (bonito fishery) like Hamashima and Wagu have their own peculiar characteristics in the form of marine raising.Investigation was made about this point from, on the one hand, a graph of the rate of increase and decrease in the population, by towns and villages, of farmers and those engaged in marine product industries; and on the other hand from a graph of the working people engaged in pearl culture by month, and by towns and villages. The following is the conclusion. In the towns and villages situated in agricultural areas, there is a great supply of potential labour, and consequently it is convenient and easy for people there to start a pearl culture industry; while in long established all-fishing settlements, labour efficiency and supply being fixed, there has very little success in forming any new industry, though there is a partial change of working power from coastal fishery to pearl culture.A region which has good communication and transportation facilities to a source of labour supply can, because of these facilities, connect closely with a peral market. Therefore, a logical conclusion would be that the area for a new enterprise largely depends upon the condition of its transportation facilities.
