Sitrang creates favorable conditions for hilsa breeding


Hilsa experts said Cyclone Sitrang created a safe environment for the spread of fish, even though it caused heavy destruction in coastal areas.

According to them, Sitrang has created a “favorable” environment for hilsa breeding. As a result, there is now a possibility of increasing its hatchability and production.

Anisur Rahman, scientific director of the Bangladesh River Research Institute (BFRI), said the water quality had improved due to heavy rains. As a result, a favorable environment for egg laying was created, thanks to which hilsa released a lot of eggs.

He said fish lay eggs at the time of new moon and full moon. This time, during the new moon, there was a lot of rain, also a lot of water and currents in the river. At the same time, due to the necessary levels of dissolved oxygen and other elements in the water, the hilsa fish got a favorable environment to lay eggs.

The hilsa researcher said the 22-day ban from October 7 will end on October 28, after which the egg-laying rate can be truly determined.

However, it can be said that because the fish can grow in this favorable environment, the quality and quantity of eggs will increase.

He said there were no fishermen and boats in the river and estuary for the three days before and after Sitrang due to the cyclone, which also created an unhindered environment for hilsa fish to spawn. their eggs.

Barisal Divisional Fisheries Officer Anisur Rahman Talukder said most of the fish spawned this time due to the favorable environment. As a result, we expect the laying rate to be 51.8% higher than last year.

“But now the challenge is to enable the eggs to be hatched and turned into big fish. This time, due to the strict operation, the fishermen could hardly enter the river. As a result, the production target of hilsa is over six lakh metric tons,” he added.

Barisal Fisheries Officer Ilish Bimal Chandra Das said most hilsa fish have already laid eggs. Eggs have also been found after examination of captured fish.

“The egg quality is also good, I think more fish will spawn than before,” he said.

A total of 22 restrictions came into force from October 7 on the capture, sale, storage and transport of hilsa in 37 districts and six sanctuaries, including the coast.

During this period, large numbers of hilsa fish lay eggs around full moon and new moon, which plays a huge role in hilsa production.
