Although our growth models for male and female 

 bonefish were significantly different, the differences 

 were small. This is reflected in our findings that in- 

 dividual growth parameters were not significantly 

 different, that the two growth curves appeared simi- 

 lar (Fig. 5), and that the maximum sizes attained by 

 both sexes were similar. Observed lengths at age for 

 females were larger than those for males in all but 

 two age classes, which is consistent with the higher 

 growth rates for females. The median length of the
