MPA Benefits - In Numbers

There is an area near Cape Canaveral, Florida that has been closed to
fishing for years though is not officially  what you would call an MPA,
simply access has been denied due to proximity to the cape or something.
Anyway, along that boundary world- record  trophy fish are being caught  for
several species and I believe that has been attributed to the closure of the
area and to spillover.  I cant recall the author's name of the paper but
perhaps someone else can.  As far as historical catch records from the same
area, I dont know if they are available or not.  Im sure someone can help
you out on this.
