water temperature was touched upon in the section for the preceding

Figure 8. --Albacore length frequency by months 

 in the North Pacific at 140°-150°E., 1950-51. 



In the northern part of the fishing ground the fishing conditions 

 are conspicuously variable, as caJi be seen from figure 2. Table 8 

 shows how the variability of the catch rate within a single sea area 

 increases to the north, particularly between 140 E. cind 150 E.
