The Halda River—the only natural fish breeding ground in South Asia—has begun showing early signs of spawning, as brood carp have started releasing sample eggs in different parts of the river.

Egg collectors confirmed that sample eggs were found at several points of the river from Wednesday night through Thursday. This development indicates a strong possibility of large-scale spawning during the upcoming tidal cycles.

Upazila Senior Fisheries Officer Mohammad Showkat Ali said the current weather conditions are highly favorable for spawning. Thunderstorms, rainfall, upstream water flow, and hill runoff have created a conducive environment in the river.

“Sample eggs have already been collected from different locations. There is a high likelihood that full-scale spawning may occur during the daytime high tide or later at night,” he added.

Meanwhile, hundreds of egg collectors along the riverbanks are already on standby with nets, buckets, and other essential equipment. Many have taken positions either on the banks or in boats, waiting to collect eggs. The news of sample egg findings has attracted more collectors to the river.

Preparations have also been completed at hatcheries in areas such as Madunaghat, Shah Madari, and Machuaghona. Officials said all necessary arrangements are in place for proper preservation of eggs and production of hatchlings.

According to the Fisheries Department, a total of 14,664 kilograms of eggs were collected from the Halda River last season. However, due to limited preservation capacity, not all eggs could be stored. This year, new wells are being constructed to increase storage capacity.

Officials are optimistic that if favorable weather conditions continue, egg production in the Halda River will be higher this season, creating new prospects for the fisheries sector.
