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.

COPE discovers fake documents covering drug imports in 2022/23

The Parliamentary watchdog Committee on Public Enterprises (COPE) has found that there were fake documents regarding the importing of medicines under the emergency procurement system in 2022 and 2023.
This was revealed during a COPE meeting held at Parliament probing the transactions of the National Medicine Regulatory Authority (NMRA).
NMRA CEO Saveen Semage told the committee that several fake documents have been found due to the lack of registration of medicines.
Stating that six such fake documents were found last year alone, Semage said he had recorded statements regarding each of the documents with the Financial Crimes Investigation Division.
He revealed that, however, no investigations have been conducted yet into the incidents.
“We have documents with confessions from a woman accepting that fake documents had been made. However, a statement has not even been recorded from that woman yet,” he said.
Meanwhile, COPE member MP Asitha Niroshana Egoda Vithana also revealed that the highest number of waive-off registrations (WOR) for medicines had been obtained in 2022 and 2023.
He said 656 such WORs had been obtained in 2022 and 261 in 2023, adding that this proves that discrepancies have taken place during the emergency procurement of medicines during these periods.
Furthermore, Deputy Director General of the Medical Supplies Division of the Health Ministry, Dr. G. Wijesuriya said discussions are underway on allowing the State Pharmaceutical Corporation (SPC) to directly import essential medicines.He pointed out that it was essential to take a policy decision in this regard as a solution to mitigate such discrepancies.

Batalanda report tabled in parliament, forwarded to AG

The Batalanda Commission report was tabled in Parliament on Friday by the Leader of the House and Transport Minister, Bimal Ratnayake.
Minister Ratnayake announced that the government has decided to forward the report to the Attorney General for legal advice. Additionally, a Presidential Committee will be appointed to provide guidance and recommendations on how to proceed with the findings of the report.
Ratnayake said that the Cabinet of Ministers, along with President Anura Kumara Dissanayake, has made a policy decision to take necessary action in response to the report. He reassured the public that steps are being taken to ensure that such a dark chapter in the country’s history is never repeated.
Minister Ratnayake said that a two-day debate on the Batalanda Commission report will be scheduled in Parliament at an appropriate time, allowing for a detailed discussion on the report’s findings and recommendations.
The report, which will be printed in all three official languages—Sinhala, Tamil, and English—will be made available to the public in the near future. Ratnayake confirmed that printed copies would be provided to members of Parliament as well as the general public for their review.
The Leader of the House further revealed that there are 28 evidence volumes associated with the commission’s work, which will be submitted to Parliament at a later date for further scrutiny.
Ratnayake said that as entire country concerned of the Batalanda Commission’s findings, the government’s commitment to addressing the issues raised and preventing future atrocities stands clear. The next steps, including legal action and policy recommendations, will be shaped by expert advice and informed parliamentary discussions, he said.

CB Governor stresses need to assist crisis-hit construction industry

Governor of the Central Bank Dr. Nandalal Weerasinghe on Friday (14) emphasized the importance of promoting a sustainable and cost-effective construction industry in the country, highlighting key challenges and opportunities in the sector.
Speaking at ‘Construction Expo 2025’, Dr. Weerasinghe underscored the need for Sri Lanka to align with global trends in sustainable construction, integrating cost-effective energy solutions and eco-friendly building practices.
“I must say my views here are not necessarily as Governor of the Central Bank of Sri Lanka, but as a person looking at this construction industry and how this can be developed and what the issues are. Sustainability in construction is essential, not just for new projects but also for existing buildings,” he noted.
Dr. Weerasinghe acknowledged that the construction sector has been one of the hardest-hit industries due to multiple economic pressures in recent years including the decline in public investments, high material costs and the industry being dependent on government projects.
The CBSL Governor, who acknowledged that the government faced fiscal constraints, limiting infrastructure spending and delaying payments to contractors, said that however, the outstanding arrears had now been settled.
“Government did not have space to spend money for public investment, especially construction that had a significant impact on the industry in the last couple of years, plus the government inability to pay the arrears for a long period. That was an issue we all recognize that has been one of the adverse impacts the industry had in the past”, he expressed.
“Also the cost of materials went up significantly, partly because of foreign exchange shortages. As a result, the shortage had shot up the prices of construction materials, as well as depreciation of the currency, high interest rates, finance costs, and other factors. We all recognize that it had an adverse impact on the industry. It’s one of the worst affected industries because of all these factors.”
