CHATTOGRAM, Nov 5, 2025 (BSS) - The government has officially declared the Halda River, which flows through Chattogram and Khagrachari districts, as a 'Fishery Heritage' area, according to a notification issued today.

The notification prohibits fishing and hunting of fish and aquatic animals in the Halda River, except for the collection of fertilized fish eggs. 

The Halda River is the largest natural breeding ground for Rui fish, whose population here is genetically pure, making it an important source of fertilized eggs. Every year, during the months of April to June, Rui fish breeding in different parts of the river produces a significant number of fertilized eggs.

The river, known for its unique ecological characteristics, is also home to the critically endangered Gangetic dolphin. The new designation aims to protect the breeding grounds of the Rui fish and conserve the habitat of Gangetic dolphins by preserving the natural environment and enhancing environmental quality. 

The designated area spans over 23,422.28 acres and includes 93,612 spots along the riverbanks.

The government has outlined several guidelines to safeguard the river including the following;

Fishing or hunting of aquatic animals is prohibited, with the exception of supervised collection of fertilized eggs during the breeding season. Activities that harm the habitat of animals or plants, or alter the natural features of land and water, are not allowed. 

Discharge of sewage and liquid waste from households, industries, or other institutions into the river is strictly forbidden.

The river must not be cut, straightened, or obstructed, and fishing is banned during the breeding season from February to July in the 17 canals connected to the Halda. 

Construction of new rubber or concrete dams, water treatment plants, or irrigation projects requires approval from the Halda River Fisheries Heritage Monitoring Committee. Any research on water or aquatic life in the river, whether domestic or foreign, also requires permission from the committee.

Engine-powered heavy vessels, such as sand-carrying boats, cargo boats, and dredgers, are prohibited in the Karnaphuli estuary section from Nazirhat Bridge throughout the year. 

Sand leases along the river and its tributaries will be terminated, and sand extraction using dredgers or other harmful methods is banned. Tobacco cultivation, use of harmful pesticides or herbicides, and establishment of brick fields near the riverbanks are also prohibited to protect the river ecosystem.

The government said these measures are intended to preserve the Halda River's ecological balance, safeguard aquatic life, and ensure sustainable use of this important natural resource.
