Locals spotted the dead fish with injury marks on Monday at the river's Kumarkhali point under the Uttar Madarsha union of Hathazari upazila

Yet another mrigal carp, weighing 7kg, was found floating in the Halda River, known to be the country’s largest natural breeding ground for carps.

It is the latest in a series of carps that were recovered in a short span of time.

Locals spotted the dead fish with injury marks on Monday at the river's Kumarkhali point under the Uttar Madarsha union of Hathazari upazila.

It is assumed that the mrigal fish (cirrhinus mrigala) had died a few of days ago, as it was recovered in a decomposed state.

Speculating about its cause of death, Prof Manzoorul Kibria, coordinator of the Halda River Research Laboratory, said: "The mrigal fish might have died after being hit by the propeller of an engine-run boat or a sand-extracting dredger.”

"The ban on mechanized boats and dredgers during the spawning season should be enforced strictly for the sake of conserving the river's ecosystem," Prof Kibria added.

On April 27, a mrigal fish weighing around 12kg was found floating on the river, and later handed over to the Halda River Research Laboratory to determine the cause of death.

On April 9, a mrigal weighing 8kg was found dead in the river's Khalifaghona point. Bruises were found on the body of the brood fish.

On March 4, a 12kg catla fish and a long-whiskered catfish were found floating on the river at Gorduara point.      

Additionally, the survival of critically endangered dolphins is also at stake in the Halda river.

On April 16, a six-month-old dolphin with scars was found floating at Madunaghat point of the river.

Plying of mechanized boats in the river is prohibited between March and July every year.  

In 2010, the government had declared 40km of the Halda river—from Nazirhat to Kalurghat—as a sanctuary for aquatic animals.
