Hilsa Prothom-alo record pictures
• Hilsa creation was 5 lakh 17 thousand tons in the most recent year
• Padma contributed around 3,000 tons
• The commitment of the Padma is diminishing regardless of whether the all out creation of Hilsa is expanded by multiple times.
Eprothom AloThe meghna stream has gone through the Nijhum Island, the last limit of the nation. At that point the estuary of the Bay of Bengal Hundreds of arrangements for the island's centers, they can go to the ocean to get the hilsa. The Hilsa from the ocean spread through the meghna on this side of Bhola-Chandpur-Shariatpur streams. A large portion of the hilsa's record created in the nation a year ago originated from this huge territory. Be that as it may, the accomplishment of getting hilsa in the Mohan and Meghna bowls of the ocean has additionally included the torment of diminishing hilsa in Padma.
Over the most recent two years, Bangladesh has risen up out of fourth to third place in the generation of regular wellsprings of fish. Scientists trust that Hilsa's commitment was to a great extent behind this. As the Department of Fisheries, the generation of Hilsa was 5,17,000 tons in the nation a year ago, of which Padma contributed 3,300 tons. In the last one and an a large portion of, the all out creation of Hilsa is about multiple times higher yet the commitment of Padma is diminishing.
Six scientists from Chittagong Veterinary and Animal Sciences University, Fish International Organization of World Fish and University of Malaysia, discover the explanations behind low yielding of the Padma in the generation of the hilsa, and the idea of their regenerative field of Hilsa in Bangladesh. For the investigation, eggs were gathered by gathering 900 hilsa from six waterways of the nation. Around 20 thousand hilsa was seen in the waterway.
Scientists state, as per the administration's declaration, disallowance of hilsa is precluded for 22 days from 7 to 28 October for hibernation and mother angling. Right now, the mother's egg laying rate was 59 percent in the Mohona and Meghna and 13 percent in the Padma. In any case, by November 10, 80 percent of the halsha eggs discharged in Padma around then there is no confinement of hilsha angling in light of the fact that the eggs are gotten in these fish. This is one reason for backing off the hilsa in Padma, specialists state.
The examination is under the Department of Fisheries and the World Fish joint activity Eco Fish, Bangladesh. In the event that you need to know, Abdul Wahab, the head of Professor and Eco Fish Project at Bangladesh Agricultural University , advised Prothom Alo that because of the different activities of the administration, the generation of hilsa expanded in the nation. When known as the fish of the hilsa angle, it is presently in the compass of the working class. Be that as it may, to bring a wide range of individuals under acquiring power, the creation of the hilsa ought to be expanded further. Along these lines, the time of endorse of hilsa in Padma can be broadened upto the principal seven day stretch of November.
Aside from this, contamination and hilsa's method for passing the Padma have turned out to be filled in sediment. Scientists state that the yield of the hilsa is low accordingly.
Gotten some information about the condition of fish and animals. Ashraf Ali Khan said to Prakash , "We have taken numerous activities to secure the nation's hilsa amid the investigation of the researchers and their counsel, whose achievement has expanded the yield of the hilsa in the nation. In the event that the hilsa in the Padma is laid eggs in November, we will absolutely do the time of disallowance of hilsa in November for the Padma. It will be chosen by our analysts and after that it will be chosen. "
Three sorts of hilsa lay eggs in three zones
In this investigation, researchers have distinguished three types of hilsa. Researchers have discovered that hilsa is hereditarily not the same as Padma and Jamuna, Meghna and Kushiyara and Bay of Bengal and its estuarine regions. They don't lay eggs other than their very own regions, they don't grow up. In the wake of being transformed into jats, they went to the ocean. On the off chance that the season of laying eggs, they would return to the waterway once more. The waterway of a stream does not go to the next waterway.
It has likewise been found in the investigation that, following two weeks of hilsa's eggs in the Meghna and Bay of Bengal, hilsa of Padma achieved its origination Padma. Furthermore, lay eggs there.
Gotten some information about this, one of the individuals from the exploration group and the instructor of Chittagong Veterinary and Animal Science University M Asaduzzaman told Prothom Alo that, 'swimming the other way of the sea by intersection the hilsha of Padma achieve the Padma. Because of the poor water and natural fixings found there, they taste a great deal. Sustenance is likewise more. Our exploration has discovered how to build the creation of hilsa in Padma. "
