The aku is a pelagic fish of very wide range. It is a surface swimmer 

 and can make about twenty-five miles per hour. They travel in schools 

 and take bait easily. They feed on young half-beaks, sardines, and plankton; 

 they often jump clear of the water when feeding. Their enemies include 

 the larger tunnies and the spearfishes. 



It is interesting to note that C. M. Cooke, Jr., reported "one school, 

 several years ago, off the north coast of Oahu about 90 miles long and 

 10 miles broad. Individuals of similar size assembled in certain parts of 

 the school." 



The aku is circumtropical in its distribution. It is a pelagic species in 

 all warm seas. It is common in Hawaii during the summer months.
