ANNEX A. PERMISSIBLE CATCH 



With present information it is not possible to give figures for the 

 optimum sustainable yield, or for the levels of population which would 

 provide such yields. Such figures can only be estimated with any useful 

 precision from the analysis of the populations after they have been 

 exposed to exploitation for a period. 



It is suggested that if catches do not exceed the following safety 

 levels until the results of such analysis are available, then the popula- 

 tions will not be reduced below the level giving the optimum yield.

 year
