In data-poor situations with little or no
information about target species status or
ecosystem processes, EBFM may simply
involve using natural history and general
knowledge to develop precautionary setasides
or safety margins, such as reduced
catch limits or larger closed areas. In systems
with moderate amounts of data (e.g.
catch data and abundance trends for key
species), EBFM could be characterized by
effective single-species management with
the addition of precautionary set-asides for
unknown ecosystem components
