The waters adjacent to the Philippine Is„ are the original home of 

 the skipjack schools which migrate to Japano Schools of all types are 

 universally distributed throughout the area and the fishing season is all 

 year round, but the peak season is from Octobdr to January, when schools 

 of "island skipjack" which migrate close in to the coast are fished, 



U. South Sea Islands 



The South Sea Islands area is in the deep part of the Pacific Ocean, 

 and from the Carolines group in the low latitudes, it stretches intermit- 

 tently east and west for about 2,000 miles. At the center, the Marianas 

 chain runs northward, and the Marshalls form the eastern limit where they 

 extend for 700 miles north and south. Among these archipelagoes, the North 

 Pacific Equatorial Current and the Equatorial Countercurrent flow in 

 complicated patterns, and migratory fishes of the surface waters are 

 distributed everywhere. Accordingly, skipjack schools may be seen through- 

 out the area at all seasons of the year. / Insert Fig, U.J 



The schools in this area are the source of the schools which migrate 

 into Japanese waters, and it may be said that the fluctuations of the 

 skipjack in these waters control the Japanese fishery, 



5. Borneo, Celebes (English Territory) 



The skipjack schools in Borneo waters come so extraordinarily close to 

 shore that they are taken with a type of weir called a keiron . The fish 

 are universally distributed throughout these waters. In the Celebes 

 area, the fishery is centered around Menado, Ternate, and Sangi I,, and 

 dense schools are widely distributed, 



6. Halraahera, Sangi Is, (Netherlands East Indies) 



Halmahera, Talaud I,, Sangi Is, The skipjack schools which occur 

 between these islands ar« large, and the fish range in size from 2 kan 

 £16.5 lbs._7 to 160 morame / 21,2 oz„_7, 



7. Ambon I, (Malacca Is.) /"Moluccas ?_7 



Skipjack schools come in close to the coasts and are widely dis- 

 tributed in the waters east and west of this island. 



8. Australian area 



The fish are distributed from southern Queensland to northeastern 

 Tasmania and St. Helen's I,, with the waters off Victoria as the center. 

 The fish also migrate into the waters off New Zealand and Lord Howe I. 

 They are from 1.4 to 7,3 kilograms in weight, with schools of four-year 

 old fish weighing 2,7 to A= 5 kilograms making up 8056 of the pooulation. 

 This is similar to tjje make-uo of the schools on our Sanriku /^North- 

 ea8tern_/ grounds, / Fig, 5.J7
