SKIPJACK IN HAWAII FISHERY 



291 



Hawaii may be explained by the nature of tlie 

 fishery there, wliich is based hirgely on semi- 

 resident popidations of small skipjack. Other 

 populations of small fish are known to occur in 

 inshore areas of leeward Oahu (oL) , and these are 

 usually exploited wjien the large skipjack are in 

 low abundance and produce the intermediate aver- 



age weight for zone 5L. Zones oW and 2L are 

 more remote from Honolulu than is 5L, and it 

 seems probable tliat the fishery in fliese zones may 

 be biased in favor of ])er-iods when lai'ge skipjack 

 are available, which could account for llie rela- 

 tively greater average weight per fisii in these 

 zones of the hshei'y.
