Sectioned sagittal otoliths of cutlassfishes, Tncluurus spp. in transmitted light. (A-D) T leptunis. 

 (E-H) T. nanhaiensis.A: age: 0+, PL = 237 mm; B: age: 1+, PL = 296 mm; C: age: 2+. PL = 361 mm; 

 D: age: 3+. PL = 384 mm; E: age: 1 + , PL = 299 mm; F: age: 2+, PL = 340 mm; G: age: 3+, PL = 

 404 mm; H: age: 4+, PL = 421 mm. Magnification = 30x, Ar = artifact, arrow indicates growth ring, 

 scale bar = 1 mm. 



Von Bertalanffy growth curves for sexes conil)ined are 

 depicted in Figure 7. No systematic trend was found in 

 the residual plots for all regressions. The <„,,,^ (age at 

 95% of asymptotic length) of T. lepturus and T. nan- 

 haicnsis were L^.l and 12.4 years, respectively. The IV 



(asymptotic weight: estimated by substituting PL^ to 

 the preanal length-weight equations) of T. leptunis and 

 T. rumhaienais were 2025 g and 2585 g, respectively. 

 Log-transformed age-at-length regressions were signifi- 

 cantly different between sexes (ANCOVA: T. lepturus:
