Fishes spawn for second time in Halda River

The fishes released eggs at Azimer Ghat, Napiter Ghona, Amtua and Ramdash Munshir Hat areas of Halda River

After a gap of almost a month, the brood fishes (mother fish) of some indigenous species released eggs for the second time in the current season in the Halda, also known as Bangladesh’s largest natural breeding ground for carps.

Noted Halda River researcher Prof Dr Manzoorul Kibria told the Dhaka Tribune that the brood fishes started releasing eggs on a trial basis on Friday afternoon and began spawning in full swing from night.

“The fishes released eggs at Azimer Ghat, Napiter Ghona, Amtua and Ramdash Munshir Hat areas of Halda River. This time around spawn collectors with more than hundred boats could collect 150-200 kg of eggs from the 98-km long river,” said Dr Kibria.

Previously on May 22, the brood fishes spawned for the first time in the current season.  

According to District Fisheries office, a total of 25,536 kg of eggs were collected from the Halada on May 22.   

During the Bangla months of Baishakh and Jaishtha (April and May) every year, different species of mother fish, like Catla (Catla catla), Ruhi (Labeo rohita), Mrigal (Cirrhinus mrigala) and Kalbaoush (Labeo calbasu) start migrating to the spawning ground of the Halda from rivers like Karnaphuli, Matamuhuri and Sangu.

The Halda which flows through Hathazari and Raozan upazilas of Chittagong, considered as the only natural breeding ground in the world where these species of fish release their eggs at a certain period of the monsoon and fry-collectors catch those eggs through a unique method to sell it to the fish farmers across the country.

After collecting the eggs, the fishermen keep the spawn in the artificial small mud pond or “kua” on the riverbank where the fry are hatched within 18 hours. After hatching, the fries are then sold out to the fry collectors or hatchery owners.
