The facts which may be gathered from the foregoing table 

 can be listed as followss 



lo The fishing gradually improves from November on, and 

 is very good in January and Februaryo 



2o In the area between the Equator and about 6° N,, the 

 schools appear to be dense, and there is little variation in 

 fishing conditionso 



3c Variations in the fishing conditions appear to be 

 somewhat more marked south of the Equatoro 



4o The fishing is conspicuously poor in the coastal 

 waters of Java,, 



5o Fishing north of 6° N„ is inferior to the fishirig 

 south of that latitude, 



6o Fishing is good around November in the coastal waters 

 of the Lesser Sunda archipelagOo 



7„ Big-eyed tuna are most abundant around December and 

 gradually decrease thereaftero 



8o The spearfishes seem to be most abundant around 

 February, somewhat later than the big -eyed tunac 



9, In the coastal waters of the Lesser Sundas the yellow- 

 fin are largeo 



lOo From the average size of the yellowfin, the catch rates p 

 and the composition of the catch it is thought that there are 

 boundaries near 6* II„ >, near the Equator, in the vicinity of 

 Sunda Strait, and in the vicinity of Lombok Straitj, and that the 

 schools which occur on each side of these boundaries are different. 



It has been said that the size of yellowfin differs by 

 regions, and if this is represented graphically for the sake of 

 clarity, we get figure 28o This graph is based on surveys made 

 between the west coast of Sumatra ajid the Nicobar Islands, and 

 the average weight of the yellowfin taken in each survey has 

 been plotted for each d egree of latitudeo
