Table 50. --Fishing conditions at 20° to 30° N. , 130° to 

 140° E. 



Note: The number of fishing stations is 105 from 20 to 25 N. and 590 from 25 to 30 N. 



Seasonal changes in the fishing conditions are not well known because of the scarcity 

 of data, but table 51 shows what is known. 



Table 51. --Fishing situation by months (20 to 25 N. , 

 130° to 140° E. ) 



Note: There are no data at all for months other than those shown on the table. 



As the data are almost entirely limited to the winter, it is not possible to give jtny 

 details on the fishing conditions in the summer, however, the data for July indicate that yellowfin 

 are fairly abundant at that time ajid the spearfish catch rate is also high. There appear to have 

 been almost no catches of other species. Yellowfin are shown to be fairly abundant for a 2- to 3- 

 month period centered around Decernber. Bigeye tuna are fairly numerous in November and 

 December and increase also in February. Albacore are extremely scarce, but some are taken in 

 the winter. Spearfishes are most abundant in July and are scarce in the winter. 



This pattern appears to coincide in general with the trend of fluctuations in abundance 

 izx the adjacent East Formosa Sea area on the west, although there are Sonne differences in the 

 values (see table 45). 



Table 52 shows the fishing situation by months north of 25 N.
