Why??? There's nothing to gain closing down an entire fishery, we're still only talking about the last 100 fish in 60-70 tributaries so small it's virtually impossible to fish. Remember, downstream of the point where 1 CT shows up with 1% RB genetics has become hopelessly polluted in terms of preserving pure WSCT. There is absolutely no point of shutting down the entire Highwood because the very upper reaches of Cataract may have 30-40 pure WSCT left... to me at least, the listing of WSCT is more about protecting the source of the few wild natives we have left.
