Monday was not a lucky day for Shafiul Alam, a middle-aged egg collector from the Madarsa area of Chattogram. After toiling hard from dawn to dusk, he kept on staring at the Halda river till late in the evening. He was unable to reconcile with the fact that his catch in the Halda river -- the sole breeding ground for natural carp in this country -- did not match his expectations. Shafiul was not alone. Hundreds of egg collectors like him, who eke out a living by selling their catch, returned disappointed, attributing their "bad luck" to lack of rains and flash floods in the region this year.

Full moon, high tide nothing helped, as our egg collection was not what we had expected," another fisherman told UNB in a choked voice. The Halda river is the only natural fish breeding ground in Bangladesh, where the carp species release eggs from April to June almost every year for time immemorial.
