THE BUZZ ABOUT ECOSYSTEM-BASED MANAGEMENT
We thought we’d
join the crowd and start to use the term that seems to be trickling into the
vocabulary at most of the marine resource discussions going on all around us.
Many are convinced that this is the way to go for future managing of all
our ocean waters. Ecosystem-Based Management; there we’ve said it and it does
sound profound, scientific and perhaps even philosophical.
The
question is, however, what does it mean? There
are some who feel that they have it all figured out and still others who
haven’t got a clue. The truth is
there hasn’t been any final judgment on exactly what the term should mean.
Once that debate is finally settled, the next question will be what to do
with it.
The
Stellwagen Bank Sanctuary is just one group that has been wrestling with an
ecosystem based management concept and has quoted as a guide, the U.S.
Commission on Ocean Policy’s suggestion as to what it should mean.
It goes like this:
“Ecosystem-based
management looks at all the links among living and non-living resources, rather
than considering single issues in isolation.
This system of management considers human activities, their benefits, and
their potential impacts within the context of the broader biological and
physical environment. Instead of
developing a management plan for one issue (such as a commercial fishery or an
individual source of pollution), ecosystem-based management focuses on the
multiple activities occurring within specific areas that are defined by
ecosystem, rather than political, boundaries.”
Okay, that
sounds pretty good, so now what?
Taking a
look at what is included for an “ecosystem”, we could list such things as
fish stocks, habitat, water temperatures, food supply for fish species –
plankton etc., water quality, impacts of various commercial projects, fishing
operations and the great mystery term, the North Atlantic Oscillation theory.
We won’t go there right now on that last term.
Suffice to say, there might be other considerations but those listed
probably cover most of the items.
Fishermen
actually have been discussing these issues for some time but may not have
realized it. An example of this has
been the frequently mentioned predator-prey relationship.
Managers and their “Plans” have brought back one fish stock just to
find that these recovered stocks tend to devoir another species and so
management plans turn to restoring the other affected species and the circle
goes ‘round and ‘round. Bass
and cod stocks are growing. They
eat lobsters and a lot of them. We
then work to protect lobsters and raise more food for the cod and bass.
How about the dogfish, that don’t exist, but do and they eat
everything? What about water
temperatures, water pollution, habitat disruption and how they affect fish
stocks and plankton feed? Some of
these factors, as we’ve seen, drive species away rather actually killing them
but they all can affect an ecosystem.
It all
boils down to a balancing act but that hasn’t, so far, been the way Ocean
Management has been handled. It’s
been one species or one project at a time and we haven’t been very successful
at looking at what one decision made has done to another part of the marine
system.
There are now a
number of workshops being planned to discuss this whole concept and here comes
another question or two. How do we
settle into one unified definition of ecosystem-based management and then how
can this be moved into the fishery management arena?
The answers to
these questions are still floating somewhere amid the waves but are likely to
wash ashore soon. It is perhaps
time for those in the fishery management system to figure out how to look at a
bigger picture then just always hitting the fishermen over and over again and
placing the blame on the fishing side of the equation.
You can’t have a healthy marine ecosystem and healthy fish stocks
unless the balancing act is accepted as being necessary and a better job is done
to achieve it.
The buzz is
balancing natures marine bounty.
