The Halda river, the lone natural breeding ground of carp-like fish in South Asia, has seen a poor yield of eggs mainly due to heavy salinity in the river water this year.
Saline water entered the river from the sea due to cyclone Yaas. Besides, there was absence of favourable natural phenomena, including heavy torrential rain, gusty wind and thunderstorm, which contributed to the poor breeding of fish, said an eminent Halda researcher.
Brood fish spawned on Wednesday night.
Several hundred egg collectors on both banks of the Halda in Hathazari and Raozan upazilas were frustrated as they expected more eggs this year for the decrease inmanmade activities that pollute the Halda.
