Illegal fishing in Charanbeel threatens native fish species

Mustafa Kamal Nannu :

The century-old Charanbeel, a significant natural wetland in Kalihatiupazila of Tangail, is facing an ecological crisis. Once home to dozens of native fish species, the beel is now overrun by illegal fishing practices, especially the widespread use of banned China Dhoari nets.

Despite a six-month annual ban on fishing to protect the ecosystem, enforcement is weak. Currently, over 2,000 illegal nets remain active around the clock, threatening fish reproduction. The once-thriving biodiversity is rapidly disappearing.

Around 230 licensed fishermen and hundreds of others from nearby villages depend on this beel for their livelihood. Once rich in fish like bata, rita, boal, chingri, koi, magur, and baim, the wetland now yields only a few species, and in declining numbers.

Industrial pollution from nearby textile factories, especially untreated dye waste, has further worsened water quality. Additionally, tourism-related waste is clogging the beel, adding to the damage.

Kalihati’s fisheries officer, Md. Ayyub Ali, confirms the overexploitation and says that seasonal bans, restocking, and awareness campaigns are ongoing. However, locals claim these efforts are insufficient.

Environmental scientist Prof. Dr. ASM Saifullah from MBSTU emphasizes that human-induced causes-pollution and encroachment-are the main reasons behind biodiversity loss. “Without enforcing environmental laws, things will only get worse,” he warned.
Local administration, including mobile court operations, has destroyed several illegal nets recently, said UNO Md. Khairul Islam.

CharanBeel’s future now hinges on decisive government action, including restoring water flow, stopping pollution, and offering alternative livelihoods to fishermen. Without urgent steps, this ecological heritage may soon be lost.
