Table 109 shows changes in fishing conditions from month to month.

Table 109. --Fishing conditions by nnonths (35 to 40 



N., 170° to 180° E.) 



The data are almost entirely concentrated in November and December, so it is 

 difficult to show clearly the chajiges in fishing conditions from nnonth to month. Judging from 

 what is shown in the table, the bigeye gradually increase from October to December, reaching 

 their maximum catch rate in the latter month. Like the bigeye, the albacore also increase with 

 the paissage of time from October on and attain a catch rate of 9. 5 in December. In January the 

 catch rate is slightly under 23, but because there are so few data it is not clear whether or not 

 the rate is always that high, however, it may be considered that there is a possibility of a fairly 

 high catch rate. The striped marlin tend to decrease gradually from October on, while the 

 broadbill appear to increase somewhat in December. The shark catch rate shows a tendency to 

 decrease gradually after October. 



It can be seen that the conditions described above coincide perfectly with those in the 

 area of 35 to 40 N. , 160 to 170 E. , which lies adjacent on the west. Only in the case of the 

 albacore in January is there a marked difference, but this is considered to be due to the paucity 

 of the data. It also appears that conditions here are in general agreement with the situation in 

 the area of 30 to 35 N. , 170 to 180 E. , which lies adjacent to this area on the south.
