vessel A was most successful among the ves 

 sels. Vessel A, which ranked among the lowest, 

 caught only 179.3 kg. of skipjack per bucket of 

 bait compared with vessel F, which ranked 

 above average with catches of 225.3 kg. per 

 bucket (table 3). 



A vessel with a high catch rate per bucket of 

 bait used may be termed efficient in its bait 

 use, but if the bait conserved dies before it can 

 be used in fishing, then it appears that a vessel 

 with a lower catch rate per bucket of bait is 

 just as efficient if a high percentage of its bait 

 results in production of fish. From examina- 

 tion of the Aku Catch Reports at the Hawaii 

 State Division of Fish and Game, we found that 

 vessel A used 78 percent of the bait it caught, 

 whereas vessel F used only 59 percent. The 

 1 fact that vessel A had the largest bait capacity 

 among the seven vessels and vessel F the 

 smallest also accounts for the rates at which 

 both vessels used their bait in fishing. Evi- 

 dently vessel F was too economical with bait and 

 the result was that it had smaller catches and 

 fewer successes in fishing the schools. Over- 

 all, the seven vessels used about 66 percent of 

 the bait they caught.
