The Indus River dolphin is the world's rarest marine mammal, found in a small area of the Indus River in Pakistan. It is nearly blind, with small eye openings, and its population has declined to less than 600 due to threats from fishing nets and pollution in the river. To protect the endangered dolphins, officials are calling for a complete ban on fishing in the dolphin reserve to prevent accidental killings and the use of harmful chemicals.

4. WHY ARE DOLPHIN’S ENDANGERED
ANIMALS?
• There are less than 600
dolphins left of this species.
• These kind of unique
dolphins are threatened by
fishing nets and commercial
killing.
• Other species in danger is
the black or Chilean dolphin,
which lives off the coast of
Chile in the Pacific ocean.
• There are other dolphin
species which are becoming
threatened too, but not as
those above.
5. HOW TO PROTECT BLIND
DOLPHINS?
The death of 24 endangered dolphins
in the river Indus, Pakistan last year has
led to recommendations for a complete
ban on fishing in their reserve.
Officials from the Sindh Wildlife
Department have become concerned at
the use of chemicals by local fishermen
within the reserve, which are being
blamed for the majority of reported
river dolphin mortalities.

7. NEW PROTECTION OF INDUS
DOLPHINS
The death of 24 endangered
dolphins in the river Indus,
Pakistan last year has led to
recommendations for a complete
ban on fishing in their reserve.
Officials from the Sindh Wildlife
Department have become concerned
at the use of chemicals by local
fishermen within the reserve, which
are being blamed for the majority of
reported river dolphin mortalities.
The 210km long reserve was
established in 1974 between the
Guddu and Sukkur barrages in an
effort to protect the endangered Indus
blind dolphin, Platanista gangetica ssp.
minor, the population of which was
thought to be as low as 150 at the
time.
