Management analyses 
We also conducted a multispecies stock assessment 
and management analysis with the estimates of fish- 
ing mortality to examine if current exploitation lev- 
els are commensurate with sustainable fisheries. 
Although 46 exploited reef fish species had been seen 
or captured in the visual and headboat surveys, only 
35 species had population dynamics parameter sets 
sufficient to conduct a management analysis (Table 3). 
We noted striking similarities in key relations within 
taxa as shown by the somewhat discrete clusters of 
taxa when maximum size dependent on maximum 
age for a variety of species was plotted (Fig. 5). Mean 
F estimates for visual survey and headboat data were 
used to encompass conservatively the range of fea- 
sible fishing mortality rates experienced in the fish- 
ery over the last two decades. A comparison of meth- 
ods and data sources also allowed us to consider risks 
associated with the overall uncertainty bounds for 
each stock assessment. Results of an example assess- 
ment analysis is shown for gray snapper in which
