In table 91 this area has been divided into sections of 2 of longitude and fishing 

 conditions in each of these sections are presented.

On the whole, black tuna and yellowfin are present only vestigially, and do not appear 

 to be centered on £iny fishing ground. Bigeye catch rates show a clear tendency to be high in the 

 east and low in the west. The albacore show high catch rate values everywhere, but they are 

 particularly high in the west. Spearfish catch rates show some tendency to be higher to the east- 

 ward and lower to the westward. 



Fishing conditions by months are shown in the following table.

Since data are almost entirely lacking for the summer, changes in the fishing con- 

 ditions throughout the year are not clear. The table shows only small catches of black tuna in 

 January and February and some yellowfin in November and December. The bigeye catch rate 

 increases twice, once in March cind April and once from October to December. The albacore 

 catch rate increases rapidly after November and attains a peak of slightly more than 15.0 in 

 January. The situation in March is not well known because of the paucity of data, but the trend 

 appears to be for a rapid decline in the catch rate in Mjirch and somewhat of an increase in
