The maximum length is 15 cm. The body is flat. The jaw is elongated. The upper jaw is slightly longer than the lower one. The fish may be known to all Bengalis who are small fish lovers and food lovers. I’m talking about the wind. Once upon a time there were many canals. Hopefully, this fish has not become so rare yet despite the unbridled oppression of nature. Many such fish are now on the red list of the International Union for Conservation of Nature (IUCN). They make this list to understand the current state of endangered animals. Who can say that this will not happen even in the fate of Batasi. The fish could not be farmed as it was not possible to produce fry artificially. So this time Bangladesh Fisheries Research Institute (BFRI) made it possible. After five years of research, their scientists have been able to produce air fry through artificial insemination. As a result, it will be possible to cultivate the fish in open water as well as in closed water.
BFRI has been conducting relentless research for two decades on native fish that have become extinct or are about to become extinct from open water bodies such as canals, beels and rivers. The purpose is to produce artificially fry in ponds or enclosed ponds to commercially cultivate fish. Their success in this case is like envy. They have been able to produce 26 more endangered fish fry before Batasi. The importance of their achievement can be understood by hearing the names of the fishes: Pabda, Gulsha, Shing, Magur, Koi, Mahashol, Guji Ayr, Rajputi, Gania, Sarpunti, Chital, Meni, Tangra, Foli, Gajar, Angus, Khalisa, Balachata, Kunchia, Kalbaush, Bhagna, Bata, Datina, Bairali, Gutum and Dhala.
As a result of all these innovations, in the last 10 years, there has been a revolution in the cultivation of small fish, the production has increased almost three and a half times. In the middle of the market, there was almost no local fish. And to go or get, the price was skyrocketing. Now there is a lot of local fish, the price is also affordable.
At present, research is underway on breeding and farming methods of some endangered fish including Dhela, Shoal, Baim, Rani, Kajali, Batasi, Kakila, Kaon, Vollar We hope that scientists will succeed in all areas. The biggest thing is, there are more fish. According to the data provided by IUCN in 2015, about 64 freshwater fish are on the verge of extinction. These also have to be brought back.
