The traditional biodiversity and fish stocks of three major rivers in Sarishabari upazila are on the verge of collapse due to the rampant and unchecked use of banned fishing gear, including "China Jaal" nets and electrocution devices.
The Jamuna, Jhinai, and Subarnakhali rivers, which flow through this region, are witnessing the widespread use of these destructive methods both day and night. This has sparked serious concern among local environmentalists and conscious citizens, who are demanding immediate and strict government action against these illegal traps.
Local sources report that organized syndicates are operating freely, using these illegal nets to catch thousands of fish of all species daily. A lack of monitoring and awareness from the local administration and fisheries department has allowed this crisis to escalate.
Each of these monofilament "China Jaal" nets can stretch from 50 to 100 feet in length. Furthermore, under the cover of darkness, fishermen use electric shocks to stun and catch fish. They travel to the middle of the rivers on boats equipped with large batteries and iron rods to administer the shocks.
A visit to the riverbanks reveals a grim sight: thousands of bamboo poles planted across the riverbeds, each serving as an anchor for a deadly net. These traps are not only depleting fish populations but are also indiscriminately killing other aquatic life, including crabs, snails, and beneficial insects, pushing the rivers toward a silent, lifeless state.
The illegal operation follows a daily routine. The nets are set in the afternoons and evenings, only to be retrieved the following morning. The catch is collected, and the nets are left to dry on the riverbanks.
Local residents expressed grave concerns, stating that these syndicates are even targeting fish eggs (fry) and juvenile fish that appear with the inflow of new water, which they then sell in local markets. They warn that if the use of "China Jaal" is not eradicated immediately, the rivers will be left with nothing but water, leading to a severe protein crisis for future generations.
When contacted, Debjani Bhowmik, Senior Fisheries Officer of Sarishabari Upazila, acknowledged the severity of the problem.
"China Jaal nets are extremely damaging. They catch everything from adult fish to fry, which is a major threat to our rivers," she said. "We are trying our best to stop these illegal nets. We have already conducted raids at several points on the rivers and at businesses selling these nets, and have also run mobile courts. Many nets have been seized and burned. Our drives are ongoing."
