Sustainable
Tourism and Knowledgeable Choices When We Order Fish
 |
It
has become obvious to me that fish species that we eat in our favorite
Caribbean restaurants has a lot to do with the populations of fish
on our local coral reefs and that only through education can the
visiting tourist learn to lessen his impact on local fish resources.
No one visiting our Caribbean Sea wants to be known as the BozoTourist,
the one that knows very little about the ecology of the coral reefs
and its amazing creature populations. That type of tourist has more
negative impact on our local ecosystems than almost any other factor,
mainly because it is driven by economics, which has a bad reputation
as a guardian of our dealings with our planet. Put the two negatives
together, the Bozo Tourist and economics and catastrophe is not
far behind.
Let me explain: On the Yorktown Clipper, a small, 110 passenger
explorertype cruise ship, we visited the chain of islands known
as St Vincent and the
Grenadines. On one particular island, Bequia, I noted the many fish
traps , each marked on the surface by empty Clorox bottles. Local
fishermen owned particular traps and their duties included emptying
them periodically of the catch of fish and selling it to the local
restaurants, as well as re-baiting the traps when needed. They usually
used animal hides as a long-lasting bait in the traps. But because
of this, algae built up in great
masses inside the traps and the surrounding populations of algae
eating species were particularly vulnerable to getting caught, such
as members of Surgeonfish, Parrotfish, Damselfish families, which
naturally eat algae. I could easily compare the diversity of fish
on this island with other Caribbean islands that we visited. In
summary, the reefs were in awful shape, and obvious overpopulation
of algae was having crucial negative effects. The water clarity
was awful, the green color of healthy coral was replaced by the
browns of dead coral that had been overtaken by an abundance of
algae.
Fish traps on this island were legal, and that was fifteen years
ago, and I wonder if it is still legal. The problem with the Bozo
Tourist is that on the menus in the restaurants, fish were mislabeled
as “greenfish”, or “bluefish” rather than
stoplight parrotfish or blue tang. Asking your waiter would not
improve your education on locally available fish that occurred on
menus. They would not know exactly what the fish species was except
it is very good tasting. This meant that the gullible tourist would
initially try an item on the menu, and find it delicious, making
it easier next time when a
choice had to be made. The Bozo Tourist was hooked, if you can pardon
by pun. The tourist pushes the market for fish served in the restaurants
and this keeps the fishermen happy as well as the local economy,
yet I questioned whether the reefs were happy? I do know that the
algae bloom showed that the algae were quite happy with this arrangement.
After that summer in 1994 as a naturalist on board the Yorktown
Clipper, I visited Bonaire as part of our scheduled itinerary. It
was at the end of my contract with the cruise ship. Perhaps because
of the obvious differences that I saw here on the reefs compared
with the islands that we visited, I decided to move here. If I hadn't
seen how bad reef conditions could be that are under human control,
and the drastic differences with Bonaire's reefs, I might not have
ever put two and two together, and I might have gone back to my
beloved Colorado.
So what fish do I order in my favorite Bonaire restaurants? I obviously
will only order fish species that I am 100% positive is from a sustainable
population. I will not visit a restaurant in which I do not know
and trust the waiter, because I'm going to ask him questions about
the “Catch of the Day”. For example, what kind of grouper.
Red grouper is hand-lined at depths off the west side of Klein that
exceed 500 feet. I see the small fishing boats anchored out there,
and I have seen them bring their catch to the restaurants and the
Red Groupers are easy to recognize as are Red Snapper, also caught
at depths- their eyes have popped out of the eye sockets because
the fishermen bring them up so rapidly from great depths that pressure
equalizations are not maintained and the expanding air spaces behind
the eyes actually burst. Quite gory, but direct evidence
as to where they were caught.
I will not ever eat “grouper” even if it is the only
species of fish on the menu that particular day, because there is
a good chance that some fisherman has spear-fished, or snorkel-fished
a local shallow water Tiger Grouper or one of the other larger grouper
species that we see and census when we do fish surveys for the organization
REEF. If the economic conditions force fishermen to fish illegally,
then they go after the largest fish. The fishermen do not know it
but they are targeting the largest fish of the groupers which invariably
are males. When grouper spawning full moons come around during the
winter months, there is a preponderance of smaller, females and
not enough males for sustainable populations. The illegal fishing
can take place at night and no one is the wiser, except the fish
surveyor. If we use the data that we fish surveyors have been contributing
to REEF for the past fifteen years, and if we look at the survey
results of the Expert fish surveyor, you will notice that the sighting
frequency of Tiger Grouper has steadily gone down:
Expert Sighting Freq %
| 37 |
Tiger
Grouper |
63.8 |
1993
to 1998 |
| 58 |
Tiger
Grouper |
58.5 |
1998
to 2003 |
| 84 |
Tiger
Grouper |
40.7
|
2003
to 2008 |
I have chosen 3 time periods, the first in which the Tiger Grouper
was listed asthe 37th most common fish on Bonaire surveys was from
1993 to 1998.
The second time period, when the Tiger Grouper slipped from 37th
overall to 58th place was from 1998 to 2003, and the third time
period , from 2003 to 2008, and you see that Tiger Grouper has now
dropped to 84th place. Also the Expert Sighting Frequency for Tiger
Grouper started out at 63.8 % and currently is only 40% as sighted
on surveys turned in by the Expert fish surveyors. Something is
going on here. We are losing our Tiger Groupers and illegal fishing
by spear-gun, or the legal method (but notsustainable) of snorkel-fishing
may be one reason, and it may be driven by not being
choosy enough when ordering fish from our local restaurants.
If I were to go to Ramon, Marine Park Manager, as a concerned diver
and tell him that I think that the number of Tiger Groupers are
much lower now than when I first started diving on Bonaire, fifteen
years ago, the wise and knowledgeable Ramon, would be courteous
and thank me, but not put too much faith in my remark because it
is Subjective Data. However, if I approach Ramon with data that
I have just explained, he would take immediate notice, because such
data is Objective Data, and based on scientific protocol.
What species on Bonaire would I order? Wahoo and Dorado are caught
in the deep blue and rarely if ever are seen over the reef, so any
fish that is caught by line, except snorkel-fishing is a sustainable
fishery, because there is no selection process where only the biggest
fish of a species are caught.
But what about your conscience and your fish choice in the U. S.?
Not much good going on .
A link to an article about the mislabeling of fish when purchased
at fish markets in the eastern U. S. should also be read by the
savvy tourist and can be found at http://www.sciencedaily.com/
I have put together some links so you can learn what species can
be ordered and which should leave you feeling good about your fish
consumption:
http://www.environmentaldefense.org/
http://www.blueocean.org.
Which is put together by Carl Safina, author of the most inspiring
book that I have read since living on Bonaire for fifteen years,
called Song for a Blue Ocean. He actually was a speaker on one of
Bonaire's Dive Festivals.
http://www.mbayaq.org/cr/seafoodwatch.asp
Which is a good one from Monterey Bay Aquarium and lists your choices
depending on the region of the U.S.. that you live in.
