Researchers discover new variant of Sri Lankan aquarium fish
by Ifham Nizam
A new variant of a popular Sri Lankan aquarium fish has been discovered by local and foreign researchers.
The freshwater fish, genus Rasbora, (commonly called ‘dandiya’) is one of the most diverse groups of freshwater fishes in tropical Asia.
In Sri Lanka, previous studies have shown that there are five species (Rasbora dandia, R. microcephalus, R. wilpita, R. naggsi, and R. armitagei) of which the last three are endemic to the island. This diversity is remarkable when compared with peninsular India, which is about 25 times the size of Sri Lanka but contain only four species of Rasbora.
Biologists earlier believed there were only five varieties of the popular aquarium fish endemic to Sri Lanka. However, with the discovery of the sixth species, Rasbora has gained a new reputation among Sri Lankan freshwater fish breeders, hobbyists and harvesters.
The researchers carried out multiple analysis using “finer geographic sampling and greater sample sizes”, thereby corroborating the validity of six species of Rasbora (scientifically called as ‘Cyprinidae’) in Sri Lanka.
The team of researchers have combed a sampling of 90 sites across Sri Lanka to identify the new species. The team consisting of Hiranya Sudasinghe of Evolutionary Ecology and Systematics Lab, Department of Molecular Biology and Biotechnology, University of Peradeniya, Rohan Pethiyagoda of Ichthyology Section, Australian Museum, Sydney, NSW, Australia, Ranasinghe Hettiarachchige Tharindu Ranasinghe of Butterfly Conservation Society of Sri Lanka, Malwana, Rajeev Raghavan of Department of Fisheries Resource Management, Kerala University of Fisheries and Ocean Studies (KUFOS), Kochi, India, Neelesh Dahanukar of Indian Institute of Science Education and Research (IISER), Pune, India and Madhava Meegaskumbura of Guangxi Key Laboratory of Forest Ecology & Conservation, College of Forestry, Guangxi University, Nanning, China.
Sudasinghe told The Sunday Island that more extensive sampling of Rasbora in India, and analysis based on multiple markers may reveal “a more complex phylogenetic topology” (diversity).
“The Sri Lankan diversification derives from a common ancestor which arrived from India during a sea-level low-stand in the mid-Miocene (15.1 Ma [95% HPD: 11.5–19.8 Ma]), when the present-day island was sub aerially connected to the Indian subcontinent by a broad isthmus”, he added.
Rasbora is generally believed to have arrived in the island from the Indian sub-continent centuries ago when Sri Lanka stood geographically merged with India. In the latest study, researchers confirm this belief.
“Our analysis suggest that Sri Lankan Rasbora derive from a Mid Miocene, India to Sri Lanka dispersal”, he noted, and added that Sri Lankan Rasbora diversity is higher than that of the Indian peninsula.
The Sri Lankan diversity of Rasbora provides an opportunity to understand the evolutionary and phylogenetic relationships of freshwater fishes in the island. Understanding the bio geography, phylogenetic and the evolutionary relationships of species are pivotal in formulating effective assessments of the conservation status of species as well as to draw up species conservation management plans.
However, such studies are still at very early stages when it comes to the freshwater fishes in Sri Lanka.
The first-ever molecular phylogeny of Sri Lankan Rasbora and reassess the taxonomic identities of the five species of Sri Lankan Rasbora based on an island-wide survey. In this study, based on molecular, morphological and statistical analyses using finer geographic sampling, validate the five putative species of Rasbora previously recognized in Sri Lanka.
In addition, a new species of Rasbora was discovered from eastern Sri Lanka. This new species was named Rasbora adisi. The species name “adisi” means mysterious or enigmatic in Sinhala: an allusion to the cryptic nature of this species.
The new species is found in eastern basins in Sri Lanka such as Gal Oya, Menik River and Kumbukkan River and show the closest resemblance to Rasbora naggsi. However, the new species is different from R. naggsi by a combination of morphological characters in addition to been genetically distinct.

Govt. confident of 2/3 majority despite NPP split speculation
By Shamindra Ferdinando
The ruling NPP yesterday (21) dismissed claims of a widening rift, within the government, over the proposed 22nd Amendment. Asked whether the NPP was concerned over a section of the Opposition alleging Prime Minister Dr. Harini Amarasuriya and two dozen MPs taking a view contrary to that of the party in this regard, authoritative party sources said some persons were propagating speculation for their own interest.
Declaring that there was absolutely no issue regarding the controversial Amendment, sources emphasised once it was tabled in Parliament, it would be passed with 2/3 majority.
Sources dismissed claims that out of its 159-member parliamentary group a section of NPPers was opposed to the government move. According to an influential Opposition activist, there are 57 JVPers and 66 NPPers in the government group and the rest contested the last parliamentary polls, having aligned with the JVP.
Ministerial sources told The Island that the government was confident of going ahead with the 22nd Amendment and Judicature (Amendment) Bills. Sources said that the NPP was not bothered about the Opposition protests in and outside Parliament.
Speaker Dr. Jagath Wickremaratne is expected to disclose the confidential ruling that he received from the Supreme Court in respect of more than 65 petitions for and against the 22nd Amendment and Judicial Amendment Bills. The enactment of the 22nd Amendment would pave the way for extending the retirement age of Supreme Court judges, from 65 to 67 years, and Court of Appeal judges, from 63 to 65 years.

Protest against setting up of cement factory in highly populated area near BIA
… school alleges deception
What began quietly as a single-storey tourist hotel, on the edge of Katunayake-Seeduwa has, five years later, morphed into a looming five-storey cement factory and with it, a storm of fear, anger and unanswered questions.
At a media briefing held on 19 September at St. Thomas International School, Seeduwa, the community finally found its voice. The gathering included priests, school principals, environmental defenders, and parents whose children study within a few hundred metres of the site.
The briefing was led by Rev. Fr. Jude Chrishantha Fernando, Director of National and Archdiocesan Catholic Social Communications, Rev. Fr. Nilantha Heshan, Director of the Archdiocesan Sethsarana Institute, Dinusha Nanayakkara, Convener of the Archdiocesan Committee for the Protection of Muthurajawela, and Attorney-at-Law Ms. Isuri Rodrigo.
Their message was clear: This is not a campaign against development.
“We Are Not Against Cement. We Are Against Deception.”
“Cement is an essential raw material for the country. We have no opposition to any such factory or production plant,” they told the media. “But what we cannot agree to is a project of this magnitude, in this location, without any proper environmental assessment.”
The speakers alleged a textbook case of deception, obtaining approvals for a low-impact tourist hotel, in one of the most densely populated educational zones in the Katunayake-Seeduwa Municipal Council area, and then transforming it into a heavy industrial plant.
“In an area where thousands of schoolchildren study, to show one thing on paper and build another is a highly fraudulent procedure. It is clear that the real environmental damage and the truth have been hidden from the people,” they said.
With the sea and lagoon winds that sweep across Seeduwa, experts fear these fine particles will not stay confined to the factory walls. They will drift across classrooms, homes, and the Katunayake Free Trade Zone, where thousands of workers, representing all 25 districts of Sri Lanka, work every day.
“The risk is not local. It is national. We are talking about a future generation of children with respiratory illnesses, and workers developing chronic breathing disorders,” one speaker warned.

Then there is the proximity that defies logic, just 500 metres from the Bandaranaike International Airport.
The panel presented a scientific concern that has aviation experts worried: a significant drop in air quality around the airport and its runway, and the severe risk to highly sensitive aircraft engines when they ingest air mixed with cement dust. What is at stake, they argued, is not just health but the economy itself.
“When you weigh it deeply, the economic contribution of an international airport is far higher than that of a cement factory. If international airlines start to avoid Katunayake due to safety and air quality concerns, it will be a fatal blow to our country’s economy,” they emphasised.
A few minutes away lies another victim the Negombo Lagoon and the Muthurajawela wetlands, Sri Lanka’s largest and most sensitive coastal ecosystem.
The panel warned that cement dust settling on the mangrove system could degrade water quality, disrupt the delicate salinity balance, and directly interfere with fish breeding grounds. For the fishing communities of Negombo, whose lives depend on the lagoon, this is an existential threat.
“The lagoon is a nursery. If its water quality drops, fish will not breed. If fish do not breed, an entire fishing community collapses,” they said.
The speakers alleged that while the developers claim to have approvals from various state institutions, many of the mandatory clearances, particularly comprehensive Environmental Impact Assessments and feasibility reports, have not been obtained.
They stressed they are not calling for an end to investment, but for it to be done right.
“We have no objection to this factory being started in another suitable location where it will not cause these environmental impacts, based on proper feasibility and assessment reports. Stop this construction here and move it,” was the unanimous demand.
The appeal has now been directed again to the President, the government, and all responsible state institutions and officials.
As the briefing ended, one image lingered — a school playground, a lagoon, and a towering cement structure rising between them. It is a scary picture for the people of Seeduwa; they asks a simple question: What price are we willing to pay for development that doesn’t breathe?
