Researchers out to save Kakila fish from extinction

Bangladesh Fisheries Research Institute is currently on a roll and writing one success story after another in its quest for artificial insemination of endangered indigenous species of fish and the latest one has come in regards to Kakila.

The institute, which has won the Ekushey Padak in native fish conservation research, hopes that these achievements will have a huge impact in the conservation of endangered indigenous fish as well as contribute to higher production of native fish in the country.

While talking to UNB, the researchers of BFRI said that at one time indigenous species of fish could be found in abundance in inland waters, but many of these have either disappeared or on verge of being extinct due to damage to habitats and breeding grounds triggered by climate change, natural disasters and other man-made causes.

But scientists working in the Jashore centre of BFRI have recently made huge progress in inventing artificial breeding techniques for such species of fish. They have achieved this after three years of intensive research.

The chief scientific officer of BFRI Jessore substation Dr Md Rabiul Awal Hossain, senior scientific officer Shariful Islam and scientific officer Shishir Kumar Dey conducted the study.

Consider Kakila, once found in plenty in inland fresh water bodies including rivers, ponds and haors’ (a wetland ecosystem in the north eastern part of Bangladesh).

The onion meals made out of Kakila are like nectar to the foodies.

It is not only a tongue pleaser, but this fish is also rich in beneficial nutrients for the human body.

Researchers told UNB that per 100 grams of edible kakila fish contains 16.1 per cent protein, 2.23 per cent lipid, 2.14 per cent phosphorus and 0.94 per cent calcium which is much higher than other small fish.

According to the scientists, Kakila ,(Xenentodon cancila, Scientific name) is recognised as Freshwater garfish  in English. It belongs to the Belonidae family of fish.

Apart from Bangladesh, the fish is found in Sri Lanka, India, Pakistan, Myanmar, Malaysia and Thailand. However, there are some differences in colour and size.

The head of the research team Md. Rabiul Awal Hossain said that the body of Kakila is long ,slightly compressed and almost cylindrical in shape. They are 25 to 30 cm in length. Also the body of the male fish is more slender and slightly smaller in size than the female fish.

It is a predatory fish. It mainly eats small fish. It breeds in naturally flowing water bodies especially in rivers and in flooded areas during monsoons.

Mature fish live in places where there are no floating aquatic plants, but their females lay eggs under the leaves and floating roots of aquatic plants.

For this near-extinct fish researchers have some good news. The researchers have discovered artificial breeding techniques for Kakila.

Rabiul claimed that this is the first artificial insemination of Kakila fish in Bangladesh and no information has been found about the artificial insemination of this fish anywhere in the world.

Senior scientific officer Shariful Islam, a member of the research team, explained to UNB on how they conducted the research.
