The Halda River is the only natural carp spawning ground in
Bangladesh and as a only tidal river in the world. Every year from
this river, fertilized eggs of carps (Rui: Labeo rohita, Catla: Catla
catla, Mrigal: Cirrhinus mrigala and Kali Baush: Labeo calbasu)
are collected by local fishermen and egg collectors between April
and June.
Why is the Halda a Natural Fish Spawning Heritage of
Bangladesh ?
UNIQUE RIVER
www.haldariver.org
The Halda River is the living natural gene bank andthe sole breeding ground of pure Indian major carpsin Bangladesh. In other sources of the carps, fishesbecome hybrids due to inbreeding problem.

NATURAL GENE BANK
www.haldariver.org
The eggs from the Halda play a significant role in thenational economy. Hundreds of egg collectors living on boththe banks of this river collect eggs from April to June andturn the eggs into fry by releasing those into the wellsexcavated on the river banks. Later, these are sold in thelocal markets at high prices.

ECONOMIC CONTRIBUTION
www.haldariver.org
The Halda River is one of the major sources of fresh water for the port city of
Chittagong. The Chittagong Water Supply and Sewerage Authority supplies
2 million gallons of water daily from this river.

Inaugurated 20 August 2017
THE HALDA RESEARCH LABORATORY HAS THREE PARTS:
• Well equipped Specialized Laboratory
• River Museum and Archive
• Digital Conference Center
THE MAJOR OBJECTIVES OF HRRL ARE:
• To facilitate specialized research like physical, chemical and biological parameters of the
environment and ecosystem of rivers
• To archive Halda River resources, history, culture and heritage
• To develop Halda River indigenous technology
• To checkup Halda River health regularly
• To establish a CENTER OF EXCELLENCE for research on the rivers in Bangladesh
