This coming September, Secretary of Commerce Donald Evans will be
making a final “finding” on the question of whether chasing and netting
dolphins to catch tuna causes “significant adverse impacts” on depleted
dolphin populations (see EIJ Summer 2002). His decision, which by law is supposed to be based on
scientific research, will determine whether or not the standards for
the “Dolphin Safe” tuna label will be weakened or not.
In anticipation of this finding, environmental and animal welfare
organizations and many scientists provided comments to the National
Marine Fisheries Service (NMFS), a branch of Secretary Evan’s
Department of Commerce, on the terrible toll the tuna fishery has taken
on dolphins.
It is becoming increasingly clear, based largely on studies conducted
by scientists with NMFS, that despite low reported kills of dolphins in
tuna nets, dolphin populations are not showing a corresponding increase
in numbers. In fact, two of the most depleted dolphin populations - the
Northern spotted and Eastern spinner - show little sign of recovery
over the last ten years of low reported mortality, and may in fact be
decreasing in numbers.
Why? There are several proposed reasons. To quote from a letter sent to
NMFS signed by nineteen biologists, including Dr. Paul Spong, Dr. Roger
Payne, Dr. Albert Myrick, and Dr. Paul Forestell:
Reported impacts of the intentional chase and capture of dolphins by
the tuna purse-seiners include spontaneous abortion of dolphin fetuses,
separation of calves from mothers, gradual separation of dolphins from
the original herd to decrease the number of dolphins in the nets,
unobserved injuries caused by chase boat propellers and illegal use of
explosives to herd dolphins, bleeding injuries on dolphins counted and
released as “alive,” dolphins showing major indications of being
catatonic within the nets, disruption of feeding, mating, and caring
for young, and increased vulnerability to predation by sharks. It is
clear from recent NMFS surveys of dolphin populations in the ETP that
the depleted Eastern spinner and Northern offshore spotted dolphin
stocks are not recovering, despite low reported mortality, and that the
tuna fishery is the most plausible cause of this lack of recovery,
given the weight of peer-reviewed scientific research conducted to
date. Other proposed causes so far lack strong scientific evidence,
pending further investigation.
Jean Michel Cousteau also echoed these sentiments in a letter to NMFS:
“Weakening those (Dolphin Safe) standards would be contrary to the
public’s interest in protecting dolphins and it would be a public
deception. Harassing and killing dolphins can in no imaginable way be
considered safe for dolphins.”
Earth Island Institute’s International Marine Mammal Project (IMMP)
submitted 22 pages of detailed comments about the scientific evidence
and showed that a finding by Secretary Evans could never claim that the
tuna fishery poses “no significant adverse impacts” on depleted dolphin
populations. Secretary Evans’ predecessor in the Clinton Administration
tried to make just such a finding, but a lawsuit by IMMP led to two
court decisions (Brower v. Evans) protecting the integrity of the
“Dolphin Safe” tuna label. In conclusion, IMMP wrote:
“The Secretary of Commerce must make his final Finding on the basis of
science, not the failed politics of ‘free trade’ and a dysfunctional
international agreement.”
The Mexican government - at the behest of the handful of millionaires
that control the tuna industry - has threatened to take the US to the
World Trade Organization tribunal if the Secretary does not gut the
meaning of the “Dolphin Safe” tuna label for them. This would allow a
flood of tuna stained with the blood of dolphins, falsely labeled
“Dolphin Safe,” into the US.
What You Can Do: Send a letter immediately to Secretary
Donald Evans, US Department of Commerce, 14th Street and Constitution
Ave., NW, Washington, DC 20230. Urge him to keep the current strong
standards for the “Dolphin Safe” tuna label (e.g. no chasing and
netting of dolphins) in place this fall, when he makes his finding
pursuant to the International Dolphin Conservation Program Act. Tell
him you will not buy tuna caught by netting dolphins. For further
