Survey uncovers rare fish
by Nilma Dole
A random freshwater fish survey carried out by the Wildlife
Conservation Society of Galle (WCSG) has uncovered a rare fish known as
the Fairy Rasbora, (scientific name: Rasboroides nigromarginata). This
rare species was considered nearly extinct as it was found after 53
years.
According to President of the WCSG Madura de Silva, the fish species
was thriving in the area of Athwaltota. He said, “We consulted renowned
fish scientist Rohan Pethiyagoda who identified the fish as Rasboroides
nigromarginata. It is just two centimetres long and was first described
in 1957 by H. Meinken, a German scientist, who received some specimens
through the ornamental fish trade.”
He said, “Although he knew it was from Sri Lanka, he had no idea
where exactly the original population was, and the species has remained
a mystery until we discovered it recently. However, Athwaltota is one of
the few water bodies that sustain plenty of endemic and endangered
species. “We can advise and create awareness about protecting this area,
but it’s up to the authorities to declare these areas as protected
reserves.
“Key environmental authorities like the Department of Wildlife
Conservation, Central Environmental Authority and Ministry of
Environment have some of the strictest laws, but they should be
implemented to make sure that people realise the value of nature
conservation.”
