and reproduction, but that tradeoff should be shown, 

 not imposed. The methods used in the present study 

 can be extended to address this tradeoff (i.e.. Mangel 

 and Clark, 1988; Clark and Mangel, 2000), but that is 

 a subject for another study. However, for many over- 

 fished stocks that need stock-recruitment relationships 

 for rebuilding analysis, this method is especially ap- 

 propriate because it indicates the ability of the popula- 

 tion to recover from low abundance. For other depleted 

 stocks, use of prior probability distributions based on 

 this method can provide useful information on how 

 quickly the populations could be rebuilt under various 

 management policies.
