 collected fron fl>hermen> the catch landed at other porti beeldee Mleakl amounted to aboat 

 6 percent of the total Mandated Xelande catch taken hy all Japaneie-based Teeeel*. The 

 catch talcen by lon£ line tana Teeiels baaed In the Mandated lelanda wae aleo Inalgniflcant 

 (Table 19). Therefore the record* kept by the Mlsakl Tlahernen'* iasoolatlon tell vlrtoally 

 the entire etory of Japan*** tana operation* In the South Sea* for epeole* other than the 

 •kip jack (Table 20). 



Beoord* are complete for all Mleakl tana lon£ line operation* In the weetem Pacific 

 Ocean. They not only ahow the extent of tuna operation* In the Mandated laland* prior to 

 World War lit but permit conparlaon of flahlng efficiency between major fishing area*. The 

 Mleald. catch record* are preeented In three oategorle*: Japaneae water* from 30'>-40<>H lat- 

 itude: Byukyu and Bonln water* from 24°-.'V)0H latitude; and Mandated laland water* from the 

 equator to 340H latitude (Table 80). The fishing day* per Toyage and the average tonnage 

 of tha Teasel* operating in each of the three ar^a* are known for 1939. This permits cal- 

 culation of the average catch In aetrle tons per flehlng day per ton of vessel (Table 21). 

 On the basl* of these datat the mandated area, with a higher catch per unit of effort, was 

 profitably operated despite the distance Involved and the difficulty of fishing without 

 shore facilities. The principal tpecles taken was yellowfln tuna, followed igr sizable quan'- 

 titles of big-eyed tana and blank narlint with lesiser amounts of albacora» *wordfl*h» and 

 other marlln*, and a very small number of shark*.
