Age-frequency distributions for Acanthochromis polyacanthus collected 

 from three reefs at each distance stratum from shore. Data are pooled 

 from the three sites sampled at each reef. All age estimates were derived 

 from counts of otolith annuli.

Average maximum length (L.,) varied across the shelf 

 and differences among strata were generally greater 

 than within-distance strata. The K values for all three
