The sole carp spawning river of the country is also the living gene bank of pure Indian major carps. Torrential rains with thunderstorm, regular ebb and tide and strong sediment-laden current from upper hilly terrain make the river a unique ecology for the carps to release eggs.
Collection and hatching of eggs from this river between April and June by traditional indigenous techniques provide livelihood for hundreds of egg collectors who hatch fries for sell in mud- scoops dug on the riverbank. Besides, the river supplies 2 million gallons of water to Chittagong city every day. These facts are almost unknown to mass people.
The negligence of authority, straightening of oxbow bends with illegal fishing of brood fishes and release of industrial and municipal pollutants are threatening the uniqueness of this river. Long-term plan to sustain the river is inevitable. The website’s goal is to create mass awareness through information among all facets of our country to ensure conservation of Halda and declaring it as “National Natural Fish Spawning Heritage”
