      abstract = {Exploitation frequently reduces the mean age of a fish  population,
particularly where a lack of property rights  stimulates producers to ignore the user
cost of harvest.  The authors demonstrate that harvesting a young fish bears  a
significant efficiency cost when the multiple benefits  accruing to its protection are
recognised. This is  magnified when the full complement of year classes within a  fish
population is considered. These findings identify the  importance of protecting older
year classes using  rights-based management and age/size restrictions, although  their
successful application can be problematic. In  addition, the importance of
incorporating more detail in  bioeconomic models of multiple-cohort fisheries  is
highlighted, as underestimating the magnitude of user  costs associated with the
cropping of younger fish will  promote recommendations for inefficient harvest  levels.
These factors are demonstrated in an application of  an optimal control model to the
New Zealand longfin eel  (Anguilla dieffenbachii) fishery.},
