Sri Lankan energy sector as millstone around nation’s neck
By Eng Parakrama Jayasinghe

Any economy thrives on a reliable and affordable supply of energy. This is a truism that no one has contested ever since the advent of the Industrial Revolution, when the modern form of energy elevated the human kind from the limitations of human and animal power. However, Sri Lanka has adopted a parochial view of this vital field with the authorities concerned jealously guarding the monopoly status they have carved out for themselves, both in the electricity sector as well as petroleum sector. They seem to think their duty is to meet the energy demand by whatever means with scant regard to sources of energy or the immense cost to the national economy.
The monopoly status enables them to continue this ill-conceived and short-sighted practice with dire consequences to the economy and all Sri Lankans, who are compelled to bear the burden of the cost of all the misdeeds and downright erroneous decisions of those responsible.
The CEB alone has suffered losses amounting to Rs 500 Billion over the past decade or so.Under the IMF not to incur any more losses, the government has jacked up tariffs.
So, the expectation was that the CEB would stop incurring losses in time to offer a clean balance sheet to facilitate the restructuring of it.But to one’s surprise, the media reports that this year too, CEB will run at a loss of a whopping Rs 50 Billion.
So, I believe that the titles and comments in my previous articles are quite appropriate. Some of them are given below:
Sri Lankan Electricity Sector – The Headless Chicken (15 Feb 2022) https://www.ft.lk/columns/Sri-Lankan-electricity-sector-The-headless-chicken/4-730564 A simple lesson in arithmetic on electricity sector (05 Dec 2022) https://island.lk/a-simple-lesson-in-arithmetic-on-electricity-sector/
The CEB produces its long-term electricity generation plan (LTEGP) with a time horizon of 20 years implemented in two-year phases, but none of its objectives has become a reality so far. Of course, they will blame the government for not providing necessary funds, without ascertaining the reasons for their failure and the impracticability of a time horizon of 20 years in view of the clear evidence seen year after year.
Something else has cropped up recently—agitations by farmers in the South due to lack of water for their paddy cultivation and the Minister of Power refusing to release water from the Samanalawewa reservoir.
The CEB has forgotten its oft-repeated excuse for lack of better management of the hydro resource, claiming that the first priority of the reservoir water is for cultivation. This should have been evident from the prior warning issued by the Dept of Meteorology in April.
The occurrence of the El Nino phenomenon every 5-7 years is nothing new. Thus, it should at least be reflected in the LTEGP over several years with particular strategies to counter it in time with short term and long-term plans.
What did the CEB do to face this situation since the country experienced the unprecedented power cuts in 2022, not for lack of generation capacity but lack of funds including foreign currency to pay for fuel imports? We did not see any concerted effort to develop already proven indigenous RE resources.
But the interesting question here is why this sudden additional crisis, particularly affecting the southern farmers? While it is the southern region farmers who are affected by a scarcity of water for irrigation, the power authorities warn that only the southern region will have to face 3-to4-hour power cuts, if more water is released. Doesn’t Sri Lanka have a highly integrated national grid and widely distributed and interconnected set of generators which should form a common pool?
Isn’t there some element that is not being disclosed here? There has been a long-delay in the construction of a transmission line from Polpitiya to Hambantota, depriving the CEB of flexibility in using such facilities. It has now been revealed that the mere 600m-long section over a tea estate has been holding up the completion of this 150 km power line. Where is the accountability of the CEB or the Ministry?
The 100 MW Solar park in Siyambalanduwa, which has been on the drawing board for many years, if implemented, would have added a substantial amount of low-cost renewable energy to the national grid, thus enabling the release of water of Samanalawewa for agricultural use.
The 2022 debacle should have prompted the CEB and the Ministry of Power and Energy to realise that the way forward was the rapid addition of RE to the grid, for which the private sector was ready and waiting.
The target of 70% RE contribution by 2030 still remains only a buzzword with no evidence of any pragmatic strategies or actions to reach this goal. In contrast, Nature itself has shown the feasibility of this goal, which was achieved albeit for a few days in 2022, seven years ahead of schedule, as shown below. (See figure1)
Any prudent energy minister, if not the planners at CEB, should have viewed this as a good omen for reaching the target of 70% RE with immense value to the economy, balance of payment, energy security and environment as well as to the prestige of the country. There is absolutely no shortage of RE resources in the country and our own entrepreneurs and engineers have demonstrated the commercial viability of harnessing all the diverse sources of such energy at no cost to the utility. There is no other country in the world where nature has bestowed such bounty.
But in sheer contrast both the CEB and the Ministry have allowed the deterioration of the energy mix to 70% fossil fuels with disastrous consequences we face now, the depth of which is carefully hidden from the people. (See Figure 2)
It does not require much intelligence to fathom that all these moves are designed to perpetuate the use of fossil fuels introduced around 1995 with most dubious terms of contract and total lack of foresight of the consequences for the future, obviously for the benefit of a few and certainly not in the interest of the nation.
It is most interesting to note the number of issues surfacing at this point of time
(a) The refusal to release water for the farmers
(b) The warnings of power cuts in the South
(c)The decision to use inordinate amount of oil for power generation over the first five months of the year, cited as needed to maintain the myth of no power cuts, as the prime demand of the people, who had got themselves adjusted to face limited power cuts, fully understanding the long term disadvantages of dependence on imported fossil fuels
(d) The lack of any information about the cost of using oil, which obviously scuttled any chance of the CEB covering the cost of generation even after the two tariff hikes
(e) The long delay in announcing a viable feed in tariff for Non-Conventional Renewable Energy (NCRE), as distinct from the major hydro power , which developed entirely by the private sector , demonstrated a remarkable growth until the debacle of huge depreciation of rupee and massive hike in interest rates badly affected such growth, and the apathy of the authorities. The tariff once announced after a two-year delay proved to be totally unbankable due to conditions imposed.
(f) Most of all, the attempt to continue the use of “Emergency Power” at massive cost using imported oil. The recent advertisement is evidence of this. Sri Lanka may be the only country in the world where there is a permanent need for “Emergency Power: year after year. It is now euphemistically called “Supplementary Power” Whom are they trying to bluff? The cost of oil -based power now costs over Rs 100.00 per unit and the Supplementary Power would cost at least Rs 135.00 per unit and mostly in foreign currency.
(g) The 14-month long delay in settling the dues to the RE developers who nevertheless continued to provide the much-needed low cost power to the national grid. However, the money and Forex needed to import oil and coal has been found by whatever means
(h) The release of large extents of lands and project approvals to the Indian Company, Adani, in total violation of the Electricity Act and without any competitive tenders. This is the ploy used by CEB to block RE projects over seven years in spite of the clear provisions for declared Feed in Tariff (FIT) for NCRE projects under the SLSEA Act of 2007.
(i) It is not yet clear what is the applicable tariff for ADANI and whether it would be paid in FOREX, which would be a clear travesty of natural justice vis-a-vis local developers.
(j) The disappearance of the Expression of Interest (EoI) received for development of RE Projects up to 50 MW capacity. It was reported that projects of cumulative capacity 600 MW were received and there was a modicum of transparency and competitive tender process.
The bottom line is clear
All these actions and manipulations could lead to achieve one single objective in spite of all declarations and protestations to the contrary. The ever-increasing demand for energy and increasing cost of inputs and services would raise expectations of many to tap that pot of gold. There is no harm at all in such expectations and entrepreneurs benefiting by transparent and fair means within the constraints of safeguarding national interests, economically, financially and environmentally, not to mention the energy security.
It would also be found that use of Renewable Energy Technologies which depend on natural elements of Solar and Wind does not present opportunities for such manipulations, nor does supply chain of fuelwood from small farmers can be exploited. As such, all activities so far are likely to result in the following:
(a) Discouraging any local developers of renewable energy, who were making very good progress contributing to the national energy supply and demonstrating most satisfactory technical competence. Some have even successfully ventured abroad.
(b) Closing the opportunity to local relatively modest indigenous investment by allowing foreign investors to develop large projects which will block the access to available transmission infrastructure and grid stations. This is reportedly already happening. It must be emphasized that all RE projects consist of a large number of small units, with even wind plants being limited to about 5 MW each. There is no reason technically or financially to aggregate them to large projects and pretend that local entrepreneurs or banks cannot fund them and put them out of their reach.
(c) The rooftop solar PV sector is devoid of any of these issues, except the reluctance and lethargy of the CEB to facilitate its rapid development, which may require only minor improvement of the grid infrastructure in some areas. This is the best way to meet the short-term energy deficits without resorting to expensive “Supplementary Power “. Perhaps, the reason for such reluctance is evident here.
(d) The slowdown of the rapid deployment of RE projects particularly the Roof Top Solar was due to the heavy depreciation of the rupee and the massive hike in bank interest rates. However, the government is blind to the opportunity of tapping many concessionary funds for low cost funding to finance the RE sector. These could also help them to develop the transmission infrastructure needed to absorb the RE generated. Such development should logically match the feasible RE development by local developers first and not to venture in to the projects proposed under the LTEGPs which never materialise
What Sri Lanka needs most urgently is for the national interest to be the driving force in the power and energy sector. Will the restructuring of CEB help achieve this objective?We expect the Minister of Power and Energy to act fast and deliver this urgent service to Sri Lanka instead of making mere tweets and declarations.

Human dignity comes centre stage in Afghan refugee deportation crisis
The mounting mute and unmitigated suffering of the ordinary people of Afghanistan is coming to the fore once again in ongoing efforts by some neighbouring states to deport tens of thousands of Afghan refugees to their country of origin. As in the case of the majority of refugees the world over the Afghan refugees too are caught up in cataclysmic wars and conflicts not at all of their making.
International reports indicate that some six million Afghan refugees have been virtually pressured, to date, to return to Afghanistan by Pakistan and Iran, for instance, on the basis apparently of stringent policies on refugees adopted by the latter. Many refugees are on record that although they are officially identified as of Afghan origin this is the first occasion on which they are seeing the inside of Afghanistan, since thus far they have been living, particularly in Pakistan, as virtual natives of the latter.
‘They are part of the biggest cross border movement of people in recent history, a UNHCR source was quoted saying. However, barring the latter UN agency and a few well wishers, the refugees are being seen as a virtual parasitic and unwanted presence by sections of the publics who have thus far been compelled to have the refugees among them.
The refugees’ haplessness is compounded by the fact that they have been reduced to almost destitution. Having possessed virtually nothing by way of material assets they are getting back to Afghanistan a dis-empowered, dispossessed people.
For well over a century Afghanistan has been at the centre of the big power rivalries of South Asia. The country has been intensely coveted by the majority of major extra-regional powers from the turn of the last century primarily on account of its strategic geographical location, besides some of its natural resources.
Those powers that gain a military foothold in the country would be enabled to bring the majority of Afghanistan’s neighbours within their sphere of influence and power. Some of these are, China, Pakistan, Iran and India. Besides there are the one time Soviet Central Asian Republics, control over whom would be of considerable value, from a number of viewpoints, to expansionist powers.
These attractions account for the appeal Afghanistan has continued to exercise over the majority of extra-regional powers whose presence has proved decisive in the shaping of international politics over the decades. Those powers who have featured majorly and are continuing to do so are, the US, Russia, China and the UK to a lesser degree.
However, the Afghan refugee issue or the ‘Long- suffering’ of the ordinary people of Afghanistan could be considered as having gained exceptional prominence with the Soviet invasion of Afghanistan of 1979.
The latter event needs to be seen as a notable turning point in the last century’s international politics. The initial disintegrative cracks in the Soviet Union were beginning to appear and Islamic fundamentalism was seen by the Soviet authorities as making divisive inroads into their Central Asian Republics.
The influence of Islamic fundamentalism had to be stymied following the Islamic Revolution in Iran in 1979 and Afghanistan came to be seen by the Soviet authorities as a potential hotbed of such religious revolutionary fervour. Thus came about the Soviet invasion of Afghanistan and its subsequent degeneration into a military quagmire for both the Soviet Union and the US.
Thus it was only a matter of time before Afghan refugees began to swell in numbers in neighbouring states. They were haplessly caught up in the ‘cross-fire’ between the Soviet backed Afghan security forces and the Afghan militant resistance which evolved into the Taliban.
As is known, the Afghan resistance came to be armed and backed by the US subsequent to Afghanistan being over-run by the Soviet Union. Thus, Afghanistan became the last proxy war theatre in the long -running Cold War between the US and the Soviet Union. More than a decade of blood-letting convinced the Soviets that there was no choice but to quit Afghanistan.
Thus, to a considerable extent, the Afghan refugees are the victims of big power armed rivalries which are continuing to render the world a most ‘dangerous place’ for ordinary people. The UN agencies seem to be doing their best for the refugees of Afghanistan and most other refugee categories but the continued humiliation of such victims of war would need to be mitigated by the international community to the extent possible. Forcible deportation of refugees in particular may need to be eschewed and outlawed.
Being subjected to an acid test at this juncture is the Universal Declaration of Human Rights (UDHR). It is the latter seminal convention that made the protection of human dignity a cardinal value for the world community.
All those sections that subscribe to international humanitarian law and democratic opinion world wide need to come together, may be under the aegis of the UN, to work out how primacy could be attached to the UDHR and its principal mandate of protecting and perpetuating human dignity and worth.
This is no easy challenge to meet but it needs to be addressed urgently before currently rampant ‘international disorder’ grows well out of control.
The US and Russia are especially obliged to go to the rescue of the Afghan refugees since the Afghan crisis is of their making to a considerable extent but no help could be expected from them because their governments are strongly right wing in orientation. It would be far-fetched to expect of them a strong social conscience.
However, the UN and like-minded organizations need to dialogue strongly with the Taliban regime in Afghanistan with a view to bettering the well being of Afghan civilians. No longer could the lot of the latter be allowed to be dismissed by the Taliban government as ‘an internal matter.’
If the Taliban regime is being assisted by the UN, the former is strongly obliged to be accountable to the international community. The UN would need to non-obtrusively convince the Taliban government that it cannot ignore the essential needs of its civilian populace and the empowering of women forms a central component of this broad programme of work. The UN’s diplomatic finesse needs to come to figure here in a major way.
Refugees everywhere should ideally be re-accommodated in their countries of origin or native lands. However, unless and until their dignity is ensured by governments and other quarters that matter such endeavours would prove to be self-defeating.

A Defence Minister after 38 years: Partnership without capture
Indian Defence Minister Rajnath Singh’s arrival in Colombo is not a ceremonial call. It is the political face of a security relationship that has been rebuilt, layer by layer, since 2024. Sri Lanka should take the capability on offer, and keep the right to say no.
by Mahil Dole
Senior Superintendent of Police (Retd.)
Indian Defence Minister Rajnath Singh is in Colombo for a three-day official visit, the first by an Indian Defence Minister in 38 years. The last such call was by K. C. Pant in 1988. That long silence itself tells a story. For nearly four decades, defence business between the two neighbours was handled by service chiefs, training colleges and quiet staff talks. New Delhi has now chosen to put a political minister at the centre of the relationship, and to do so immediately after a dense sequence of Indian visits and against a harder contest in the Indian Ocean.
The visit will be read, in Delhi, Beijing and Washington, as a signal. Our task in Colombo is narrower and more serious: to convert the signal into national capability without converting the island into a platform.
Not an isolated visit
Singh’s programme is the latest layer in an unusually concentrated Indian engagement since President Anura Kumara Dissanayake assumed office in September 2024. Prime Minister Narendra Modi’s state visit in April 2025 was the first by any foreign head of government after the new presidency. Seven documents were signed. Among them was the first comprehensive India–Sri Lanka Defence Cooperation Memorandum of Understanding, a five-year umbrella covering joint exercises, training, port calls, humanitarian assistance and disaster relief, information exchange and possible defence-industry cooperation. Either side may terminate it with three months’ notice. That exit clause is not a detail. It is the difference between a structured partnership and a treaty alliance.
What followed was a rhythm, not a one-off. The eighth Annual Defence Dialogue was held in Colombo in June 2025. The Indian Navy Chief called in September 2025. After Cyclone Ditwah, India arrived as a first responder and later announced a reconstruction package of some 450 million US dollars; External Affairs Minister S. Jaishankar came as Special Envoy. In January 2026 the Indian Army Chief, General Upendra Dwivedi, handed over vehicles and training aids, opened a friendship corner at the Defence Services Command and Staff College, and laid a wreath at the IPKF memorial in Battaramulla. The Indian Vice-President visited in April. Foreign Secretary Vikram Misri was in Colombo on 5 August with rupee lines of credit for railways and other priorities. Later that month, Sri Lanka’s Navy Commander, Vice-Admiral Damian Fernando, made his first overseas visit in command, to New Delhi, and met the Chief of Defence Staff, the Defence Secretary and the Navy Chief.
Singh therefore arrives not as a stranger opening a file, but as the political seal on work already in motion. He met President Dissanayaie, who holds the defence portfolio, the Prime Minister and the Defence Secretary. The itinerary also takes in the IPKF memorial, the Defence Ministry, the parliamentary precincts, Gangaramaya Temple, a likely reception on an Indian Navy ship, the National Defence College, and the Sita Amman Kovil in Nuwara Eliya. Indian High Commissioner Santosh Jha has said relations have “never been better” in decades. The visit calendar, at least, is not an invention.
What already stands on the defence floor
It is important to be precise about what already exists, so that we do not mistake institutionalisation for a sudden tilt.
Training is the deepest bond. India is the largest foreign trainer of the Sri Lankan armed forces, offering on the order of a thousand to twelve hundred vacancies a year. One naval accounting records more than two thousand Sri Lankan naval personnel passing through Indian courses over nine years. Shared classrooms produce shared language, shared drills and personal networks that outlast any single government. Reports ahead of this visit point to three new memoranda, one likely on air-defence guns, one on cadet-corps links, and one on cooperation between the Sri Lanka Defence College and Indian defence institutions. If signed, those instruments would push the relationship into the next generation of officers, not only today’s operators.
Exercises are now routine rather than ceremonial. The twelfth edition of SLINEX, the bilateral naval exercise, was held in Colombo from 14 to 18 August 2025, with a harbour phase of professional exchanges and a sea phase of gunnery, boarding, replenishment and communications. MITRA SHAKTI, the army exercise with air elements, held its eleventh edition in Belagavi last November. A fourth bilateral diving exercise was conducted in Colombo in April 2026. The two navies and coast guards continue International Maritime Boundary Line meetings. An Indian Navy Dornier was based here for maritime surveillance from August 2022 to August 2025. A Maritime Rescue Coordination Centre was commissioned with an Indian grant of about six million dollars. INS Vikrant and INS Udaygiri took part in the International Fleet Review marking the Sri Lanka Navy’s seventy-fifth anniversary.
None of this is trivial. None of it, by itself, is alignment. Hardware, hours at sea and staff-college seats are instruments. What they become depends on command, data and political purpose.
National security questions that matter
Three questions should govern Colombo’s handling of the Indian Defence Minister’s visit.
The first is maritime domain awareness. Sri Lanka’s core security geography is not a land frontier. It is the exclusive economic zone and the sea lanes that pass our shores. The live threats are narcotics, people-smuggling, illegal fishing, and the possible relocation of cyber-fraud compounds. Conventional naval war is not on this year’s operational list. Indian help with sensors, hydrography, diving, boarding drills and search-and-rescue is therefore rational. The test is who owns the picture. Shared awareness is useful. Exclusive dependence on one partner’s fusion centre is a vulnerability. Australia’s Disi Rela programme against irregular maritime movement, Japanese passage exercises, and the United States capacity support, cutters, aircraft, humanitarian exercises, already exist. They should remain in the mix. Maritime security should be a Sri Lankan-led coalition of convenience, not an Indian franchise.
The second is the air and coastal defence gap. Talk of Indian air-defence guns is not abstract after the 2026 conflict in West Asia reached our own waters, the sinking of the Iranian frigate IRIS Dena off Galle, and later Iranian hulls lingering near the exclusive economic zone. The government’s public line was the correct one: no combat use of our territory, airspace or waters by any party; humanity first; sailors rescued. That posture only works if the state can see, and if necessary contest, its approaches. Accepting guns, radars or training is compatible with an independent foreign policy if command, basing and rules of engagement remain Sri Lankan. Integrating them into another country’s kill-chain would not be.
The third is internal security. Easter Sunday accountability, narcotics networks that run through ports and prisons, and communal peace are not separate from geopolitics. Partners price political risk. A state that cannot govern its harbours, its financial system and its extremist ecosystems will be offered “help” that looks like tutelage. India’s interest in counter-terror coordination and drugs overlaps with genuine Sri Lankan needs. The discipline required is the same as in any sound intelligence relationship: cooperate on targets; do not outsource the service.
The wreath at the IPKF memorial will be watched, as it was when the Indian Army Chief stood there in January. The years 1987 to 1990 remain raw in our political memory. The only stable line is professional honour to the dead, not a political rehabilitation of an intervention that divided this country.
How the region will read Colombo
India’s motive is not mysterious. Sri Lanka sits on the approaches to India’s southern seaboard. Chinese commercial and dual-use presence at Hambantota and Colombo Port City, and continuing engagement with the People’s Liberation Army Navy, is the backdrop. Pakistani naval units calling at Colombo, including a Chinese-built Hangor-class submarine earlier this year, only sharpen New Delhi’s preference for a denser security habit with us. Neighbourhood First and MAHASAGAR, Mutual and Holistic Advancement for Security and Growth Across Regions, are the language. The operational aim is that extra-regional navies do not treat Sri Lankan harbours as a default logistics base against Indian interests.
Our motive should be equally clear, and different. Geography makes India the permanent neighbour. Crisis behaviour, liquidity and fuel in 2022, the cyclone in 2025, the energy and remittance shock of 2026, has already shifted public sentiment. That is a political fact. It does not require Colombo to adopt India’s threat picture of China, or to freeze other relationships.
A workable posture is polyalignment with a spine. India is the deepest security and connectivity partner, domain awareness, disaster response, training, Trincomalee energy cooperation, grid links and rupee credit, on the condition that ports, exclusive economic zone access and intelligence fusion remain under Sri Lankan law. China remains a major economic and infrastructure partner; new exclusive strategic footholds should not be created, and debt and operational control must stay visible. The United States, Japan, Australia and Europe matter for markets, green shipping, extra training pipelines and non-traditional maritime threats. Ordinary naval diplomacy with Pakistan and others is manners, not signalling.
The government’s stated doctrine, an independent policy that does not favour any country, and territory that will not be used against a third party, is the right public frame. This week will test whether that frame can coexist with deeper, more structured Indian defence cooperation. It can, if the new memoranda are capability contracts with exit clauses, not political alignment documents.
Take help. Keep the choice
Colombo should treat the expected instruments as a capability audit.
On air defence, welcome sensors and guns that Sri Lanka can man, maintain and switch off. Reject any arrangement that requires foreign crews, foreign rules of engagement, or data that only flows one way. In cadet corps and staff colleges, take the training and keep a parallel pipeline with other professional schools so that the officer corps is not a single-source product. On the 2025 Defence Memorandum, measure implementation by Sri Lankan readiness, hours of maritime coverage, time-to-rescue, interdiction rates in the exclusive economic zone, disaster lift, not by the number of Indian ship-days in harbour.
Joint training should emphasise humanitarian assistance, counter-narcotics, hydrography, diving and lawful boarding. Those are the missions that serve the public and do not lock us into someone else’s contingency. Scenarios that only make sense in an India–China or India–Pakistan crisis should be declined politely and firmly.
Defence talks must also be bound to the prosperity agenda. Trincomalee as an energy and industrial node, electricity interconnection, port productivity and cyclone reconstruction are where security cooperation either pays the citizen or looks like militarisation. A Defence Minister’s visit that produces only wreaths and signed paper will be read in the region as alignment. A visit that also moves energy storage, disaster systems and maritime safety will be read as statecraft.
I write as a former police officer who spent a working lifetime on intelligence, counter-terrorism and the unglamorous work of keeping a multi-religious island in one piece. Geography gave us a seat at the table of Indian Ocean commerce and security. Institutions, energy policy, port performance and social cohesion will decide whether that seat produces prosperity, or merely more invitations to other people’s contests.
Singh’s visit should be received with courtesy, used with discipline, and remembered for what it adds to Sri Lanka’s ability to stand on its own water. Take the neighbour’s hand. Keep the island’s choices. Make sure every exercise, every gun and every training slot leaves us more able to say no the next time a great power asks to use our sea, our air or our soil. (18 sources)

Lost for 90 years: Rare Goby resurfaces in Jaffna
Rediscovery highlights rich, unexplored aquatic biodiversity in Northern Province
By Ifham Nizam
A small fish that vanished from Sri Lanka’s scientific records for nearly 90 years has resurfaced in the waters of Jaffna, providing researchers with a remarkable rediscovery and fresh evidence that the Northern Province still holds significant, unexplored aquatic biodiversity.
The Yellow-stripe Goby, Mugilogobius chulae (Smith, 1932), was recently found in the Karainagar area of Karaitivu Island during a biodiversity survey, almost nine decades after it was last scientifically recorded from Sri Lanka.
The discovery is particularly significant because the species had previously been known from the country only through a single historical specimen collected from Pedduru Thuduwa, Jaffna.

Discovery moment
Research scientist Janamina Bandara, a member of the team that made the discovery, told The Island that the fish was not initially identified as the long-lost species.
“We came across an unidentified Goby during our fieldwork, and it was only after a detailed examination of its external morphology that we were able to establish its identity as Mugilogobius chulae,” Bandara said.
“For us, it was an exciting moment because this species had not been confirmed from Sri Lanka for almost 90 years.”
The fish has a particularly interesting history in Sri Lankan ichthyology.
In 1936, renowned Sri Lankan zoologist P. E. P. Deraniyagala described a new fish from Pedduru Thuduwa in Jaffna in his paper,
“Two New Fishes from Ceylon”, published in The Ceylon Journal of Science.
He named the species Vaimosa valigouva. Subsequent taxonomic revisions established that Vaimosa valigouva was a synonym of Mugilogobius chulae, the currently accepted scientific name of the Yellow-stripe Goby.
However, no further confirmed records emerged from Sri Lanka for decades.
With the species absent from subsequent surveys and inventories, it eventually disappeared from the country’s national fish lists and from much of the scientific literature relating to Sri Lankan fishes.
The prolonged lack of records was also closely linked to the difficulties of conducting biological research in northern Sri Lanka.

Yellow-stripe Goby, Mugilogobius chulae
For decades, the civil conflict, restricted access, security concerns and limited opportunities for field surveys prevented scientists from systematically investigating many of the region’s aquatic habitats.
Consequently, while considerable advances were made in documenting biodiversity elsewhere in the island, northern Sri Lanka remained comparatively poorly explored.
Bandara said the rediscovery should, therefore, be viewed in a much wider context than the finding of a single fish.
He told The Island: “An absence of records does not necessarily mean that a species is absent. In the case of northern Sri Lanka, there have been enormous gaps in field data because large areas could not be studied systematically for many years.”
“This finding demonstrates how important it is to return to these habitats and carry out detailed surveys. There could be many more species, range extensions and rediscoveries waiting to be documented.”
The research team’s findings did not end with the Yellow-stripe Goby.
During the same study, the researchers also documented the Black-spotted Snubnose Goby, Pseudogobius melanostictus (Day, 1876), providing what they describe as the first confirmed northernmost record of the species in Sri Lanka.
The species had previously been reported mainly from lagoonal and brackish coastal environments in the western part of the country, while recent verified records were limited.
The new finding consequently extends the known geographical range of Pseudogobius melanostictus and adds an important northern record to Sri Lanka’s fish fauna.
Together, the two findings significantly expand the known distribution of both Goby species within Sri Lanka.
They also highlight the importance of small and often overlooked coastal, tidal and inland aquatic habitats in documenting the island’s biodiversity.
Goby species are generally small fishes that occupy a variety of marine, brackish and freshwater environments. Their habitats can include rocky shores, tidal pools, lagoons, estuaries, mangroves and other transitional aquatic ecosystems.

Black-spotted Snubnose Goby, Pseudogobius melanostictus
Because of their small size and preference for habitats that are often overlooked during large-scale biodiversity surveys, some Goby species can remain undocumented for long periods.
The latest research is, therefore, particularly relevant to understanding the aquatic biodiversity of the Jaffna Peninsula and surrounding islands.
According to Bandara, the discovery also demonstrates the importance of combining historical scientific literature with modern field research.
“The old records gave us an important historical reference, while the current fieldwork allowed us to connect that history with what is actually present in these habitats today,” he said.
The rediscovery of Mugilogobius chulae effectively reconnects modern Sri Lankan ichthyological research with Deraniyagala’s 1936 record.
It also establishes the new finding as the westernmost known occurrence of the species in the Indian Ocean, according to the researchers.
The study’s authors — Janamina Bandara, Sahan Randeniya and Aravind Manoj — say their findings underline the need for continued biological surveys in northern Sri Lanka.
The region’s aquatic ecosystems remain insufficiently studied, particularly in areas that were inaccessible or difficult to investigate for extended periods.
Bandara said the team expected that further exploration could produce more unexpected findings.
“We should not assume that we have a complete picture of Sri Lanka’s fish diversity. Particularly in the north, there are habitats that have received very little scientific attention,” he said.
“Every field survey can potentially change what we know about the distribution of a species. That is why continued exploration and proper documentation are so important.
The researchers have expressed particular concern about the need to document such species before changes to their habitats make future identification more difficult.
Coastal development, changes in water quality, habitat degradation and other pressures can affect small aquatic ecosystems, making baseline biodiversity information increasingly important for conservation planning.
The latest study, therefore, provides not merely two new distribution records but also a reminder of the value of maintaining and updating national biodiversity inventories.
The researchers thanked Dr. Helen Larson, Rohan Pethiyagoda, Madhura de Silva, Dr. Kasun Bandara and Neluka Fernando for their assistance with various aspects of the study.
