Fishing for Hilsa has been banned in Bangladesh for 22 days starting on Wednesday. The ban has been in place for the past few years to ensure smooth reproduction of the hilsa fish. This year the ban will last until November 4. During this time, fishing, sale, marketing, storage and transportation will be prohibited. There are provisions for fines and imprisonment if violated.
But what is the role of hilsa in the reproduction of hilsa?
Hilsa researchers say the main purpose of refraining from catching hilsa at this time is to protect the mother hilsa so they can safely lay eggs in the river. If this egg can be protected, it will be fertilized and Jatkar will hatch. If that jatka is protected, the production of large hilsa will increase in the country.
Scientific Director of the Institute of Fisheries Research for Hilsa and Hilsa researcher. Anisur Rahman says it was at this time that mother Hilsa started laying eggs in the river. A Hilsa mother lays four to five lakhs of eggs. Our experiments show that at least 840,000 kg of eggs were released last year alone. You have seen the benefits of growing them this year.
Scientists estimate that if half are fertilized, even if 10 percent survive, 36 billion hilsa or jatka fingerlings can be found.
আমরা We are obtaining evidence that it has happened. If it weren’t for that, such a large string wouldn’t be captured day after day, ‘says Dr. Rahman. This year, the large hilsa fish have been sold in the Bangladeshi market at a much lower price. Relatively large threads have also been caught in rivers and seas.
Previously one kg of hilsa over one kg sold for a few thousand rupees, this year it was sold for less than one thousand rupees in Bangladesh.
Elora Chowdhury, a housewife from Dhaka, says: “I have never had the opportunity to buy such a large thread at such a low price. Hilsa is also quite nutritious and tasty compared to other times.
Last year, he had to buy this type of hilsa for Rs 1,500 to Rs 2,000, Elora Chowdhury said. The bigger the fish thins, the more it will taste. Many people call large hilsa as mature hilsa.
Hilsa’s researcher said. Anisur Rahman, এখন Everyone now understands that Hilsa’s production has increased. Among the reasons behind the increase in production, the 22-day hilsa ban is the most effective.
The Jatka protection program was started in Bangladesh from 2003 to 2004. Since then, Hilsa’s production has been gradually increasing.
In Ashwin’s first month since 2006, hilsa fishing was banned for 11 days before and after the full moon. Since then, scientists have started to see the benefits. Then they found in the study that not only on the full moon, but also on the new moon of this period, hilsa lays eggs.
Subsequently, the ban was imposed for 22 consecutive days in conjunction with the full moon.
থেকে Hilsa’s production has been increasing gradually from 2014-2015. Night production has increased a lot. Because even though the law existed before, it was strictly observed from then on, ”says Rahman.
He said that 5 lakh 33 thousand metric tons of hilsa have been produced in 2019.
“Hilsa used to be available before, but now, as production has increased, large yarns are also arriving, more in quantity, larger in size,” he says.
From Mirsarai in Chittagong to Lalmohan Upazila in Bhola it is the largest hilsa breeding ground in Bangladesh. Especially Monpura, Dhalchar, Balirchar, Moulvirchar – these are the most important points for hilsa spawning. Chittagong, Bhola, Laxmipur, Noakhali, Chandpur, Patuakhali, and Barguna together lay the most eggs in an area of approximately 6,000 square kilometers.
Hilsa also lays eggs in other rivers on the outer coast.
As a hilsa observation cell of the Department of Fisheries, 15 years ago, hilsa roamed the rivers of 24 upazilas in the country. Evidence of hilsa has been found in the rivers of at least 125 upazilas in the country.
After the hilsa fish lays eggs, the jatka grows and returns to the sea. Later, when they grow up, they return to the river to lay their eggs.
Its contribution to the GDP of Bangladesh is around one percent.
According to the Bangladesh Fisheries Research Institute, about 12 percent of the country’s total fishery production currently comes from hilsa.
