Figure 27. Winter Sightings of Skipjack. Biological 

 studies on the skipjack and on the principal bait fishes are being 

 carried out in cooperation with the Territorial Division of Fish 

 and Game. POFI has undertaken as its principal contribution the 

 study of skipjack at sea--primarily how and where to find them. 

 As presently envisioned, this involves, in part, systematic scout- 

 ing for skipjack by plane and vessel. Scouting carried on during 

 the winter of 1951-52 and its relation to the area of localcommer- 

 cial fishing is summarized in the figure shown above. The heavy 

 lines indicate some of the vessel tracks and the heavy broken lines 

 the plane tracks; the light dashed line outlines the Hawaiianfishery. 

 The hatched areas designate the schools of skipjack seen during 

 the cruises. Many were seen southwest of the islands and far 

 beyond the range of the present fishery.
