Hardly any albacore catch is recordedfor the SouthernHemisphere, 

 although there are some cases in Moluccas waters where there are catch 

 rates of over 1.0 but these are probably anomalous. Fishing conditions 

 in tropical waters of the Northern Hemisphere, as in the case of mid- 

 latitude waters, show no outstanding catch rates, but a certain amount 

 of albacore is tsiken generally over the area. At times there are fairly 

 concentrated catches mixed in with yellowfin and bigeye. The size of 

 the fish taken in this area, in general, appears to be somewhat smaller 

 than the fish taken in the mid-latitude waters. 



OCTOBER 

 General 



The fishing situation in low-latitude waters (0 to 10 N.) in October 

 is just about the same as in the preceding month, with no outstanding catch 

 rates but with a certain amount of fish taken everywhere. In middle- 

 latitude waters, along the line of 25 N. , we have continuous data from 

 each to west which appear to show catch rates not greatly different from 

 those of Septennber. However, there appears to be somewhat of a ten- 

 dency for the values to increase. Far to the south of the Kii Peninsula, 

 in the vicinity of 22 N. to 25 N. , 135 E. , there is an area of somewhat 

 concentrated fishing. 



1. North Pacific Area 



The fishing grounds of the North Pacific east of northeastern 

 Honshu have moved quite conspicuously southward compared with the 

 previous month, this trend toward the south being particularly marked 

 west of 170 E. Albacore fishing is a good deal more active than in the 

 preceding month, and catch rates are generally above 1 . in the area of 

 36 N. to 40 N. , between 160 E. and 175 W. , with scattered places show- 

 ing catch rates of about 5.0. 



Between 150 E. and l60 E. fishing is generally slow, with few 

 places where the catch rate rises above 1.0. West of 150 E. , where 

 there was almost no catch in September, concentrated fishing grounds 

 have developed and in some cases catch rates are better than 5.0. 



It is not possible adequately to examine annual fluctuations because 

 of the inadequacy of the past data; however, in 1949_' also fishing was
