The two-month government ban on catching selling and transporting of Hilsa began Sunday.
A 90-kilometre stretch of the Padma and Meghna rivers here have been turned into a sanctuary for Hilsa after the ban came into effect. It will be lifted on May 1.
The ban will be strictly maintained in six sanctuaries said Md Asadul Baki district fisheries officer.
The sanctuaries are- 100 km in the Meghna River from Chandpurs Shatnol to Laxmipurs Char Alaxandar 90km in Shahbazpur Channel in Bhola 100 km in Tentulia River in Bhola 40 km in Andharmanik River in Patuakhali 20 km at lower Padma (Padma confluence) in Shariatpur and 83 km in the Meghna River (from Hizla to Mehendiganj) in Barisal.
Md Asadul Baki said they conducted drives from 12am to 1:30am on Sunday but found no fisherman in the two rivers.
Mahbub Rashid assistant fisheries officer Chandpur Sadar Upazila said the authorities have declared 90km from Matlab Uttar Upazilas Shatnol area to Charbhoirabi in Haimchar upazila as sanctuary.
All the upazilas in the district have formed individual taskforce committees to strictly implement the ban he said.
Hilsa trader Shahajan Sardar Babul Hazi and Nurul Islam told UNB that a huge amount of Hilsa was caught in January and February which is considered as off season for Hilsa fishing.
They hope that the ban would boost production.
Hilsa has the highest contribution in the country's fish production as the single fish species the government says. More than 12.09 percent of the country's fish production comes from Hilsa.
In 2017-18 Hilsa production was 5.17 lakh MT which had an estimated value of around Tk 20680 crore.
