The Amazon Pink Dolphin
Volunteer Project
Two unique
dolphins have evolved to live
exclusively in the major rivers
of northern South America - the
boto or Amazon river dolphin,
Inia geoffrensis, and the tucuxi
Sotalia fluviatilis. Both of
these dolphins are fish eaters
and are among the largest
aquatic predators of South
America. Both live abundantly in
and around the Mamirauá Reserve,
where our study is based.
Freshwater
dolphins also occur in several
more of the world’s largest
river systems (Yangtze, Indus,
Ganges and Brahmaputra).
However, the pressure of human
populations in Asia, and their
destruction of river habitats
through dams, fishing and
pollution, has resulted in the
dramatic decline of dolphins in
these areas. Indeed, the Baiji
(Yangtze river dolphin) has
recently been made extinct and
Bhulan (Indus river dolphin) is
the most endangered dolphin in
the world. Only in the Amazon
and Orinoco river basins are
river dolphins not currently
undergoing obvious declines, and
that is simply due to the fact
that the human populations have
not yet exploited rivers to the
same extent. This is the good
news. The bad news is that
exploitation is currently
increasing in pace, even here.
Every dam, every gillnet, every
mercury-laden goldmine brings
nearer the day that dolphins
will be as rare in the Amazon as
they have become in Asia.
The project
is primarily aimed at providing
information and advice on which
dolphin conservation can be
based in Mamirauá and, more
generally, in the Amazon and
Orinoco basins and in Asia. We
seek to revolutionize our
understanding of the biology and
ecology of the boto and tucuxi,
identifying key habitats and the
dolphin/human interactions that
most threaten, and least
threaten, the populations of
these animals.
The project
has the following objectives:
-
1) To establish the number
of dolphins of the two
species that use the
Mamirauá reserve and its
surrounding rivers
-
2) To monitor these
populations in relation to
changing management regimes
within the reserve
-
3) To investigate the impact
of various types of fishing
on dolphins, especially in
relation to entrapment and
drowning
-
4) To investigate the impact
on dolphins of ecotourism
and other human activities
in this region
-
5) To establish the relative
use of the different
habitats in this area, and
their importance to each
dolphin species
-
6) To determine basic
population parameters, such
as age at first
reproduction, inter-birth
interval, and age-related
survival
-
7) To determine the social
and mating organisation of
the two species
-
8) To investigate the health
of Mamirauá’s dolphins and
their exposure to disease
-
9) To provide advice to
legislators and managers at
local, state and national
level, on what measures must
be taken to prevent the
decline and ultimate loss of
river dolphins in South
America
-
10) To train bright young
scientists, volunteers and
local managers in the use of
appropriate techniques and
technology to increase the
knowledge and conservation
status of fresh water
dolphins
-
11) To educate the local
people of the Mamirauá area
about the importance of
environmental care and
sustainable resource use,
and in the value of
maintaining a world in which
both they and dolphins can
live together.
The project
has been underway at the current
level of activity for several
years now, and we have a number
of achievements under our belt.
These include the publication of
four papers in international
scientific journals, and the
presentation of seven talks at
large international conferences.
To date, more than 30 young
scientists from seven countries
have been trained in dolphin
research techniques, and in so
doing have contributed to our
vast database. This now includes
more than 25,000 observations of
known dolphins!
Our most
exciting achievement is surely
the development of the pool of
marked and recognisable animals
that form the backbone of this
study and the research
techniques that allow us to
learn so much from them. It is
the daily discoveries that come
from many long hours on the
water, binoculars in hand, that
make this work so special. And
this is exactly where volunteers
can help - contributing their
eyes, data entry fingers and
financial resources to keep this
unique project pushing forward.
The rain forest is a major issue
to saving our planet from global
warming and other issues we can
not see yet. But the Rain Forest
is only one factor that we must
consider saving.
The
Pink Dolphin
is also
nearing extinction and millions
of people do not know they
exist. You can help us save
these mammals from extinction by
purchasing one of our save the
Pink Dolphin wrist bands or any
of our other products. All
proceeds go to
Save the Pink Dolphins
Campaign.

Have
you ever seen the pink dolphins?
Not many have. There are less
than 100 pink dolphins left in
an estuary of Hong Kong's Pearl
River. As they age, they get a
bubble gum pink!

Pink Dolphins can only be found
in three rivers in the world The
Great Amazon River, and Hong Kong's Pearl River.
The Orinoco River in the
northern part of South America
has Pink Dolphins but has not
been well
documented.
