Mother fishes release eggs in Halda

Mother fishes of different species have released 'sample eggs' at several places in the Halda River, the only natural fish spawning centre in South Asia.

The fishermen said they found 50 to 200 grams of eggs in some places, including Machuaghona and Nayahat, in the coast of Halda after 12:00pm on Saturday.

Hathazari upazila administration and local egg collectors confirmed the release of sample eggs.

The indigenous fish species, including Ruhi, Mrigel, Katol and Kalbaush, started releasing eggs after heavy rain due to cyclone ‘Asani’ for the last few days.

Egg collectors and persons concerned were waiting in the river as the full breeding season started from the beginning of May.

They hope that if there is heavy rain with thunderstorms on the current full moon day, mother fish can start releasing eggs in full swing in the river during high tide or low tide.

Hathazari Upazila Fisheries Extension Officer Meherun Nesa said some of the waiting egg collectors found sample eggs at several places, including Garhduara and Mardasha, Mashuaghona and Nayahat areas. However, the amount is not too much.

Halda researcher and Chattogram Cantonment Public College Lecturer Md Shafiqul Islam said if the mother fish does not release eggs on the full moon days, they will release eggs during the next new moon.

He said important physical and chemical parameters of Halda water are now standard for breeding.

Hathazari Upazila Nirbahi Officer Shahidul Alam said they have taken steps to ensure the safe breeding of mother fishes. “Steps have also been taken as none could catch the mother fishes during the breeding period.”

Besides, all kinds of assistance have been provided by the upazila administration and fisheries department to ensure the necessary facilities for the egg collectors.
