Fig. 6. Occurrence of juvenile albacore in the Pacific Ocean. Based on collections of Biological Laboratory, 
Honolulu, Hawaii {stars) and data in Yabe et al. (1958) {triangles ) . Figures in parentheses are numbers 
of specimens. 
albacore have been captured in widely scattered 
areas in tropical and subtropical waters extend- 
ing from approximately 150° E to 155° W in 
the North Pacific and 155° E to 162° W in 
the South Pacific. It would be interesting to dis- 
cover whether albacore spawn randomly in 
these broad areas or whether there is concen- 
trated spawning within them. 
SUMMARY 
Stomachs of large pelagic fishes collected dur- 
ing the period June I960 through November 
1962 were examined for the occurrence of juve- 
nile albacore. The stomachs were obtained from 
fishes landed by the Hawaiian commercial long- 
line fishery, captured during cruises of the re- 
search vessel "Charles H. Gilbert," and captured 
during the 1962 Hawaiian International Billfish 
Tournament at Kona, Hawaii. 
Twelve juvenile albacore were discovered in 
the stomachs of predators: six from five blue 
marlin, three from three striped marlin, two 
from a yellowfin tuna, and one from a wahoo. 
The juveniles were identified on the basis of 
the haemal spine on the first caudal vertebra, 
which in the albacore has a unique laterally 
flattened shape. The smallest specimen identi- 
fied by this character measured an estimated 6l
