Figure 7. — Growth curve of yellowfin tuna in the central Pacific as determined by otolith examination and compared with growth 

 curves of previous studies from that area and the eastern Pacific. Linear growth stanzas determined by LE^FIT (see text). For 

 parameters of growth stanzas, see Table 3. 



pen and Howard O. Yoshida for their editorial 

 help. We are especially indebted to Gary L. Kamer 

 and Jeffrey J. Polovina for assisting with the 

 statistical problems encountered. Marian Y. Y 

 Yong assisted with the data processing and Glen 

 H. Sugiyama verified some of the age determina- 

 tions. We are grateful to Sherry Steffel for sharing 

 her data on feeding records and otoliths of skipjack 

 and yellowfin tunas from her experiment.
