 ure 4, peak abundance usually occurred off 

 Kahului and off Kahuku Point, where Y/f aver-

 waters off the City and County of Honolulu was

The intensification of fishing in the third 

 quarter resulted usually from increased appar- 

 ent abundance in Hawaiian waters. In this quar- 

 ter, those regions in which apparent abundance
