 proximal surface longitudinally, and the depth of the 

 sulcal groove increase.^ with (ish age. 



The precision of otolith readings of P. multidens was 

 relatively high lAl^E of lOA'/i). Given the variability en- 

 countered among otoliths, this APE reflects a moderately 



high level of precision among otolith readings and indi- 

 cates that the aging protocol adopted is replicable. 



Otolith length and breadth were useful predictors offish 

 length in P. mullulcns. accounting for more than 17' i of the 

 variability (Table 2). In contrast, otolith weight and, in par- 

 ticular, height were poor predictors offish length (Table 2). 

 Otolith weight was the best predictor offish age for f! multi-
