This time, the three species of fish, the extinct fish, are returning together, but it is a less joy for the foodie, it is also a less joy for the researchers. The scientists of the Bangladesh Fisheries Research Institute located in Saidapur, Nilphamari, have recently developed the breeding technique of three extinct fish.
The chief scientific officer of the freshwater sub-centre. Senior scientific officer Ishtiak Hadar, Shaukat Ahmed and Maliha Hossain Mou led by Khondkar Rashidul Hasan took part in research. Scientists said that the extinct fish is collected from Teesta, Chikli river of Rangpur, Nilphamari river and ‘Mother fish’.
Among the three fish, Batita Pui is known as Nato, Khali Muchri, Bilvari etc. depending on the area. In the Pahai Chota River of Sylhet and Sunamganj districts and in the small rivers of Dinajpur, Rangpur and Matmonsingh districts, the fish has a capacity of 5,000 to 8,000. The breeding season of the fish is from May 5,000 to 8,000 in the month of August.
Laitya Tangra is another delicious fish in the freshwater, which is known as river tangra, laitya tangra in the regions of the country in the northwest and southeastern districts of the country, especially in the monsoon and winter season, their paotha jata jata jata jata jata jata jata jata jata jata jata kota tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang tang The fish can be found in various rivers of the district such as Teesta, Buikhora, Barati, Chikli and Bhusi rivers. For the first time, the initial success of Laitya fish fry production through artificial breeding has been achieved by standardizing the technology in the current breeding season. Research has shown that a mature (20-30 grams) weight of Laitya Tangra has an egg capacity of 25,000 to 40,000.
Kursha is a freshwater fish known as Kursha, Khursha or Katal Khushi in the northern part of the country. The fish is known as Kursha, Khursha in the northern part of the country. Freshwater water bodies are known as their habitats, especially mountain springs and shallow clear rivers are rich in production of delicious and beneficial nutrients for the human body. Research has shown that a mature Kursha fish has a large number of fertility from 50,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,0
The chief scientific officer of the main freshwater sub-centre of the research team. Khondkar Rashidul Hasan and senior scientific officer Shaukat Ahmed told Ittefaq that indiscriminate killing of fish, especially fishing in rivers and current nets, fishing in water, reservoirs, use of pesticides and negative effects of watering, he said that the fish will be brought back to the country's fish sector.
In this context, Director General of Bangladesh Fisheries Research Institute, Etahita Mahmud, said yesterday, "We have developed a breeding technique in 34 species of extinct fish, including three, and 30 species of fish are extinct. But hopefully, we can bring back all the extinct fish."
