of harvestable biomass and that mortality on young fish 
drives eventual production available to the Chesapeake 
Bay region black drum fishery. The supply of fish to the 
Bay region depends on mortality during the first ten years 
of life, years when these fish are found off the coasts of 
the South Atlantic states. Hence, management practices 
by states south of Cape Hatteras will determine the sup- 
ply of fish to this coast-wide stock.
