Study on carnivorous fish of Sri Lanka

A team of ichthyologists in their latest study on carnivorous fish of Sri Lanka points out that Channa orientalis also known as the Ceylon snakehead, is the only pelvic-fin less snakehead in Sri Lanka.

Snakeheads are one of the main carnivorous groups of freshwater fish in Sri Lanka. They belong to the family Channidae and the genus Channa. There are six species of Channa in Sri Lanka, two of which are endemic. The two endemic species are Channa ara and Channa orientalis. Channa orientalis also known as the Ceylon snakehead is the only pelvic-fin less snakehead in Sri Lanka.

The latest study on the genetic diversity and morphological stasis in the Ceylon Snakehead found that the taxonomic identity and the type locality of this species were not certain.

Scientist Hiranya Sudasinghe told The Island yesterday: “We show that C. orientalis is composed of two geographically and genetically distinct lineages but which show remarkable morphological similarity between the two lineages. The recognition of two distinct genetic lineages is important because, when it comes to conservation management of this species, these two lineages could be recognised as two Evolutionary Significant Units that would deserve separate conservation attention.”

“We argue that the type locality of C. orientalis is south-western Sri Lanka, to which the species is endemic. Channa orientalis is distinguished from other species of Channa by the absence of pelvic fins, adult colouration in life, dorsal- and anal-fin ray counts, number of vertebrae, and scale counts,” the team pointed out.

This species feeds like a ciclids, experts point out.

The team of scientists comprises of Hiranya Sudasinghe of Evolutionary Ecology and Systematics Lab, Department of Molecular Biology and Biotechnology, University of Peradeniya, Peradeniya, Sri Lanka/ Postgraduate Institute of Science, University of Peradeniya, Peradeniya, SriLanka, R.H.Tharindu Ranasinghe of Butterfly Conservation Society of Sri Lanka, Rohan Pethiyagoda of  Ichthyology Section, Australian Museum, 1 William Street, Sydney, NSW 2010, Australia, Madhava Meegaskumbura of  Guangxi Key Laboratory of Forest Ecology & Conservation, College of Forestry, Guangxi University, Nanning, People’s Republic of China and Ralf Britz Senckenberg Naturhistorische Sammlungen Dresden, Museum für Tierkunde, Königsbrücker Landstrasse 159, 01109 Dresden, Germany

As the type species of the genus Channa, the identity of the pelvic-finless snakehead Channa orientalis Bloch is important to channid systematics. Although this name has been attached to a Sri Lankan species for the past 160 years, its vaguely specified type locality, ‘India Orientali’, has long cast doubt as to its origin.

Based on a collection across its range in the island and analysis of the cytochrome c oxidase subunit 1 (cox1) barcoding gene, scientists show that the Sri Lankan pelvic-finless Channa is composed of two geographically discrete lineages separated by an uncorrected pairwise cox1 genetic distance of 6.9–8.1%.

The minimum genetic distance between these two lineages and other species of the Gachua group of Channa is 5.1%. Despite their genetic divergence, the two lineages exhibit remarkable morphological stasis: they are indistinguishable from each other in external morphology.

Prime Minister Dr. Harini Amarasuriya held a series of high-level bilateral meetings on Wednesday [January 21] on the sidelines of the World Economic Forum in Davos, Switzerland, engaging with representatives of the European Union, the United Nations Development Programme, and the global private sector.

The Prime Minister met with Hadja Lahbib, European Commissioner for Preparedness and Crisis Management. During the meeting, she expressed Sri Lanka’s appreciation for the support extended by the European Union and its member states following Cyclone Ditwa. The Prime Minister also briefed the Commissioner on the key findings of the World Bank’s GRADE report and requested continued EU support for Sri Lanka’s development and recovery efforts.

Prime Minister Amarasuriya also met with Alexander De Croo, representing the United Nations Development Programme. She expressed appreciation for the longstanding partnership between Sri Lanka and the United Nations and acknowledged the UN’s support in flood relief and livelihood assistance. The Prime Minister noted that, following the mandate received at the parliamentary election, the government is focused on meeting public expectations through national rebuilding grounded in public trust and good governance. She further reaffirmed the Government of Sri Lanka’s commitment to strengthening social protection systems and safeguarding vulnerable communities.

In addition, the Prime Minister met with Robert M. Uggla, Chairman of A.P. Moller Holding. The discussion focused on engagement with the private sector and potential areas of collaboration.

These meetings reflected Sri Lanka’s continued engagement with international partners and global stakeholders to support recovery, development, and long-term economic stability.

Opposition slams sitting HC judge’s appointment as Justice Ministry Additional Secretary

Prof. Peiris

… alleges Prez trying to control judiciary

Opposition grouping ‘Mahajana Handa’ has accused President Anura Kumara Dissanayake of trying to exercise control over the judiciary by appointing a sitting High Court judge as Additional Secretary to the Justice and National Integration Ministry.

Addressing the media at Dr. N. M. Perera Centre, Punchi Borella, on Tuesday (20) top Opposition spokesman and former External Affairs Minister Prof. G. L. Peiris warned the High Court judge D.M.D.C. Bandara’s appointment was nothing but a direct executive intervention in the judiciary.

Responding to The Island queries, Prof Peiris asked how the government could compel courts to deal with a sitting judge who functioned as Secretary to the Justice and National Integration Ministry.

Prof. Peiris explained that the latest move by the Executive should be examined taking into consideration the attacks on Attorney General Parinda Ranasinghe Jr, PC., the deliberate delaying of the appointment of Auditor General and the controversy over the process of promotions of Judicial Officers, Judges of the High Court and the Court of Appeal in Sri Lanka. Prof. Peiris pointed out that the Bar Association of Sri Lanka (BASL) had raised those controversial promotions with President Anura Kumara Dissanayake.

D.M.D.C. Bandara, Senior Assistant Secretary, Judicial Service Commission, was among altogether 18 High Court judges appointed by President Dissanayake in early Sept this year. The group consisted of 17 Special Class Judicial Officers and a Senior State Counsel serving in the Attorney General’s Department.

Referring to a recent meeting ‘Mahajana Handa’ representatives, including him had with the Mahanayake theras of the Asgiriya and Malwatta Chapters in Kandy, Prof. Peiris said that they had received the blessings of the Mahanayakes to go ahead with what he called a programme of action meant to address major issues.

Prof. Peiris said they would initiate talks with other like-minded political parties and groups in this regard soon. Referring a protest held at the Hulftsdorp on Wednesday (21) demanding the removal of the AG Ranasinghe, Prof. Peiris emphasized that the government’s hand in that demonstration was very clear. President Ranil Wickremesinghe appointed him as the AG in July 2024 with the unanimous backing of the Constitutional Council.

Prof. Peiris said that action was yet to be initiated to appoint new civil society representatives to the Constitutional Council. That issue hadn’t received sufficient public attention, Prof. Peiris said, urging President Dissanayake to come down from his high horse.

Asked whether the President could appoint a sitting judge as an Additional Secretary to a Ministry without consulting the Chief Justice and President of the High Court Judges Association, sources familiar with the issues at hand said that certain appointments could be made on secondment. However, that has to follow the proper procedure, sources said.

The Island sought a response from the Justice and National Integration Ministry to the accusations made by Prof. Peiris on behalf of ‘Mahajana Handa,’ but did not receive one until this edition went to press.
