exhausting public interest in land animals, American and English environmental
fund raising groups looked for ways to revive flagging income. They turned to
the sea and its over 80,000 species, searching for a few that would pull in the
most contributions. For this purpose the species had to be (1) familiar; (2)
photogenic; (3) threatened; (4) interesting; and (5) sexy.
Bluefin tuna met all their criteria. Tunas have been a favorite food fish all
over the world for over a thousand years. Bluefin tunas are particularly
photogenic: big, sleek and handsomely contoured. Blue-fins were highly valued
and demand for the fish was putting heavy pressure on the populations. And
bluefins were certainly interesting. The fish grew to be over two meters long
and could weigh well over 300 kilograms. They could attain swimming speeds of
over 72 kilometers per hour and migrate over 6,000 miles in a year. Sexy?
Streamlined, well muscled, warm blooded and distinctive, bluefin tunas were the
ideal "poster child" for effective money appeals.
The fact that bluefin tuna were already being managed under regional
conservation programmes did not really matter to the fund raising groups. They
were confident that they could discredit the regional tuna management
organizations with a strong propaganda campaign and convince the public that
tunas were being mismanaged.
With grants from the Pew Charitable Trust, a $4.6 billion trust fund, the
MacArthur Foundation, and other groups promoting the environmental agenda, they
did just that. Spewing out millions of dollars worth of propaganda in newspaper
ads, TV documentaries, press releases and direct mail appeals, organizations
such as World Wildlife Fund, the Audubon Society, Greenpeace, the Center for
Marine Conservation, and Earth Island Institute convinced the public that both
the Atlantic bluefin tuna and the southern bluefin tuna were on the verge of
extinction.
The environmental fund raising groups that are now feeding off the hysteria
they created for bluefin tunas would like nothing better than to persuade CITES
to list bluefins on Appendix I. A CITES listing would give credence to their
allegations and justify their efforts. It also would provide them with another
hook for their money appeals.
Arguments to list bluefin tunas on the CITES Appendices should be taken with
a large grain of salt. For one thing, as mentioned earlier, the important stocks
are already managed under sound conservation programs by the International
Commission for the Conservation of Atlantic Tunas (ICCAT) and the Commission for
the Conservation of Southern Bluefin Tunas (CCSBT). Both of these organizations
are guided by some of the world's best tuna scientists and a wide range of
experts with years of experience. They have adopted a number of measures which
have brought the populations under control and provided for an increase in their
numbers.
One of the tactics of the fund-raising groups is to point to declines in
populations as evidence of a threat of extinction. Fish populations, however,
are at their most productive when their unexploited populations are reduced by
half. That is the level at which they produce the most young and is termed the
maximum sustainable yield point.
Most fish have a high level of fecundity and can recover quickly from events
that reduce their populations to a small fraction of their original size. A
single female bluefin, for example, produces tens of millions of eggs at each
spawning.
Marine science has progressed quite a bit in the past twenty years but it is
still far from being an exact science. It relies heavily on estimates,
assumptions and probabilities, buttressed by observations, experience and
sampling. As a result, it has become a fertile field for pseudo scientists from
fund raising organizations, who substitute speculation for judgment, cloud
findings with uncertainties, and wield the precautionary principle like a scythe
to prevent sustainable use. In the world of traditional science, results are
tested through trial and error. In the world of environmental science, testing
is abandoned to the precautionary principle.
