21 November is celebrated as world fisheries day across the world. Apart from crucial source of food and livelihood to lakhs of fisherfolks in India, fish diversity determines the health of the water body including lakes, ponds and rivers. However with growing threats and pollution mass fish mortality has been taking place in various rivers and lakes in the country every year. On World Fisheries Day 2018 SANDRP has put together known mass fish kill incidents that took place this past year to highlight the gravity of threat so that corrective measures can be taken by respective Governments and others concerned.
Punjab Gurdaspur Sugar Mill Molasses release led to Beas River Fish Kill The worst mass fish death took place in Beas river in May 2018 in Punjab when 10000 kilo liters of toxic effluents were discharged by Chadha Sugar Mill located in Kiri Afgana village of Gurdaspur district. The avoidable incident grossly polluted the 80 km river stretch of river causing death of thousands of fish. The other aquatic animals like Gharial and Dolphins were also severely affected by the industrial disaster termed as one of worst incident in Punjab. Here is detailed SANDRP report on the issue. https://sandrp.in/2018/05/22/gurdaspur-sugar-mill-molasses-release-leads-to-beas-river-fish-kill/ (22 May 2018)
Contaminated water with dead fish and snakes has entered Rajasthan through the Indira Gandhi canal from Punjab, prompting authorities to stop drinking water supply from the canal as a precautionary measure. https://www.hindustantimes.com/jaipur/dead-fish-and-snakes-float-in-indira-gandhi-canal-rajasthan-stops-drinking-water-supply/story-BlwNI4xbhLeuu5pxp34sNL.html (21 May 2018)
On Nov 14, 2018, National Green Tribunal imposed a fine of Rs 50 crores in connection with this incident. The bench clubbed several similar cases, including the one dealing with death of fish due to untreated discharge from sugar Industries in May 2018. The bench headed by Justice AK Goyal asked the Punjab government to recover the fine from industries in two weeks. “Earlier a committee headed by Central Pollution Control Board, of which Punjab Pollution Control Board was a part, submitted a report saying it found that the industrial discharge was not being treated as treatment plants were not functioning,” PPCB counsel Nagendra Benipal said. https://www.ndtv.com/india-news/ngt-imposes-rs-50-crore-fine-on-punjab-over-river-pollution-1947522 (5 Nov. 2018)
Himachal Pradesh, Punjab Thousands of fish found dead in Swan river Local people on the Punjab-Himachal border woke up to see thousands of dead fish floating in Swan river along 10 to 12 km stretch from Santokhgarh in Himachal to the point where the river merges with the Sutlej in Punjab on Aug. 3, 2018. The mass fish kill apparently was the result of industrial pollution. There are two major industrial areas Tahliwal and Mehatpur in Himachal, from where waste is released into the Swan River. https://www.tribuneindia.com/news/himachal/thousands-of-fish-found-dead-in-swan-river/631572.html (4 Aug. 2018)
However instead of finding the source of pollution and taking action against culprit the Pollution Control Boards (PCB) of both states kept blaming each other for the incident. Jatin Joshi, SDO, Punjab Pollution Control Board (PPCB), said since there were no industrial units on the Punjab side on the banks of the river, effluents released from the units in Himachal might have led to the death of the fish. On the other hand, the Himachal Pradesh PCB authorities blamed Punjab Alkalis and Chemicals Limited (PACL), a Punjab Govt undertaking, for fish mortality. https://www.tribuneindia.com/news/himachal/hppcb-blames-punjab-unit-for-fish-death/632138.html (5 Aug. 2018)
Chandigarh Fish found dead in Sukhna Lake Large number of fish were found dead at Sukhna Lake on Aug. 5. While officials of the Animal Husbandry Department primarily blamed lack of oxygen in the water for the death of the fish, experts said there could be other reasons too. Dr Ravneet Kaur, Assistant Professor, Department of Zoology, PU, said in this season of high humidity, there was less exchange of oxygen between the water and the external environment. She said it happened every year these days. Experts said despite the High Court’s order, sewage from nearby areas was still flowing into the lake, which also needed to be monitored. https://www.tribuneindia.com/news/chandigarh/fish-found-dead-in-sukhna-lake/632889.html (6 Aug. 2018)
Fish found dead in Dera Bassi pond A large number of dead fish were found floating in a water body at Mubarikpur village on Aug. 17. Villagers passing along the pond found a large number of fish floating in the water body. Foul smell was emanating from the pond. The residents informed the authorities concerned about the dead fish and officials of the civic body reached the spot.
The villagers suspected that lack of oxygen or polluted water due to the release of effluents from industrial units might have killed the fish. The villagers demanded that the water of the pond needed to be tested to understand the actual reason behind the deaths. https://www.tribuneindia.com/news/chandigarh/fish-found-dead-in-pond/638810.html (18 Aug. 2018)
Uttar Pradesh Thousands of dead fish found floating in Ganga Thousands of dead fish were found floating in the Ganga on May 14, 2018. This was the fourth time such an incident has occurred in as many years. Reports suggested that dead fish were first seen floating in the river’s Kannauj stretch, after which the phenomenon was witnessed in Unnao and Bilhaur.
Effluents from industrial units in Shahjahanpur were prima facie suspected of discharging toxic material downstream, poisoning the river water. UPPCB officials suspect the presence of a poisonous substance in the Garra river, which originates from Shahjahanpur and merges with the Ganga in Kannauj. https://www.hindustantimes.com/lucknow/thousands-of-dead-fish-found-floating-in-ganga-experts-blame-toxic-effluents/story-ujQ4HnvtMVXULPYRa2XENP.html (15 May 2018)

In July 2017 also hundreds of dead fish were found dead in the Ganga near the temple town of Shukratal, in Muzzafarnagar, due to toxic industrial effluents in the river discharged by industries in upstream Uttarakhand. http://www.hindustantimes.com/environment/hundreds-of-fish-found-dead-in-ganga-near-up-temple-town/story-YGmXasnEVQNQXrkxNm7RpL.html (July 2017)
Mass Fish Death in Virandavan Countless number of fishes and other aquatic animals were found dead in the Yamuna river in Vrindavan area. Locals noticed dead fishes floating in the water on Nov. 1 near the Kesi Ghat of Yamuna.
Regional officer of UP PCB in Mathura collected samples for tests and said that water appeared to be highly contaminated, as it had turned oily and black in colour. The water is also used for irrigation purposes by farmers alongside the river. https://www.youtube.com/watch?v=Zwp9fIfoO0Y (3 Nov. 2018)
UP PCB official in Mathura said that untreated waste water, industrial effluents discharged upstream caused oxygen depletion resulted fish deaths. https://www.firstpost.com/india/ahead-of-diwali-thousands-of-fish-found-dead-in-yamuna-in-uttar-pradesh-activists-in-agra-begin-cleaning-drive-5502311.html? (4 Nov. 2018)
Meanwhile, experts rule out possibility of Delhi’s pollution to be reason behind mass fish kill in Yamuna at Virndavan on Nov. 1 and Nov. 2. “The water released in Delhi is no doubt filthy, but it won’t be right to say it kills the fish in Vrindavan. The reason for this can be attributed to local factors like industries dumping effluent or the water that flows down Kosi drain,” Manoj Misra, convener of Yamuna Jiye Abhiyaan said.
Himanshu Thakkar, of SANDRP echoed Misra’s views and said it was unlikely that Delhi’s dirty water was killing the aquatic populace at Vrindavan. “The distance and time are definite factors here. Essentially, fish die because of less oxygen or toxicity due to chemicals. In either case, the impact should have been seen much closer to Okhla barrage. The deaths may have occurred due to local sources,” Thakkar said. https://timesofindia.indiatimes.com/city/delhi/far-fetched-why-delhi-cant-take-blame-for-dead-fish-in-vrindavan/articleshow/66503055.cms (5 Nov. 2018)
Report of water samples collected by the UP PCB indicated high content of oil in it, which led to low levels of dissolved oxygen. The reason and source of pollution is still not known. https://timesofindia.indiatimes.com/city/agra/test-shows-high-content-of-oil-in-yamuna-water-sample-mathura-pcb-official/articleshow/66515877.cms (5 Nov. 2018)

Gujarat Dead fish surface in Kamlanagar pond Dead fishes surfaced in the Kamlanagar pond in the Ajwa Road area on Aug. 9 morning. The Vadodara Municipal Corporation (VMC) had recently spruced up the Kamlanagar pond at a cost of Rs. 4 crore. While the pond was cleaned up and its embankment were concretised, sewage contamination seems to have resumed in it. VMC councillor Vijay Pawar said that he had spotted the contamination some time back and even informed the top brass of the civic body. But no action was taken.
Mamlanagar pond was amongst the first to be spruced up in the city. Environmentalists had, however, raised questions about the work on the pond stating that with stone masonry embankments it had become a tank and would not be a live water body. It was after this that the VMC stopped the process of having concrete borders of ponds. https://timesofindia.indiatimes.com/city/vadodara/dead-fish-surface-in-kamlanagar-pond/articleshow/65345576.cms (10 August 2018)

Maharashtra After holy rituals, fish die at Banganga tank at Walkeshwar In what has almost become an annual feature at the historic Banganga tank at Walkeshwar, dead fish were found floating on Oct. 9, 2018, after hordes of people immersed food dumplings in water as part of the Pitrupaksha rituals. Residents from the immediate vicinity said it is a common sight every year.
According to Dr Vinay Deshmukh, Former principal scientist at Central Marine Fisheries Research Institute (CMFRI) during this ritual, cooked rice balls and wheat are immersed in water, which not only becomes food for bacteria but also increases their population. The bacteria consumes the dissolved oxygen thereby depleting it quickly resulting in mass death of fish and the only solution is to stop immersing the offerings in water. https://www.dnaindia.com/mumbai/report-maharashtra-after-holy-rituals-fish-die-at-banganga-tank-at-walkeshwar-2673544 (10 Oct. 2018)
Tamil Nadu Dead Fish set off pollution alarm in Valankulam lake Local fishermen had noticed the alarmingly sight of several dead fish floating in Valankulam lake on July 24. It was only after they began circulating pictures on social media did authorities get wind of it. As per environmentalists such mass fish deaths had happened in Singanallur and Sulur lakes for past 7 years.
They suspected water contamination with highly toxic sewage to be the reason. The latest incident was another stark reminder of the fact that the majority of the city’s sewage is being let into water tanks instead of being treated. https://timesofindia.indiatimes.com/city/coimbatore/dead-fish-set-off-pollution-alarm-in-valankulam-lake/articleshow/65124847.cms (24 July 2018)

Scores of dead fish had washed ashore at the same spot in January 2015. The site has become a graveyard for turtle too. Lab test hints pollution to be culprit but govt thinks otherwise. However the two incidents in the space of three years have left fishermen in the village worried about the impact on their livelihoods.
As per local fishermen high influx of raw sewage from upstream residential localities, industries and hospitals have led to the incident. Locals also allege that some of the industries in SIPOT at Irungattukottai, Pallipattu, Somangalam, Amarambedu and Chembarambakkam release untreated effluents into the neighbouring water streams during monsoon period, which eventually flow into the Adyar estuary. http://www.newindianexpress.com/cities/chennai/2017/nov/29/twice-in-two-years-dead-fish-wash-ashore-in-chennai-sewage-influx-blamed-1713472.html (29 Nov. 2018)
Karnataka Thousands of fish found dead in Hemavati river In March 2018, very large number of fish found dead in the Hemavati river, a tributary of the Cauvery and the lifeline of Bengaluru and Mysuru, in Banakal in Chikkamagaluru district, triggering alarm that the water has been poisoned. Locals allege that a few criminals have poisoned the river water to catch fish easily and in huge numbers.

Fish Death In Kukkarahalli Lake Apprehension was writ large on the faces of regular walkers and environmentalists, who frequented Kukkarahalli Lake as a sizeable number of dead fish was found floating on April 7 on the water in the lake especially the stretch abutting Hunsur Road. It was feared that contaminated water was responsible for the death of fish.
Environmentalists opined that owing to the huge organic load, the dissolved oxygen level in water had depleted abysmally resulting in the death of fish which was said to be happening for the last 3 or 4 days. They suspected seepage of effluent from Paduvarahalli area. https://starofmysore.com/fish-found-dead-in-kukkarahalli-lake/ (7 April 2018)
Varieties of fish at Kukkarahalli Lake continued to die with more than 40 fish found floating in the lake. The lake staff removed the dead fish. The authorities collected the samples of dead fish and have sent the same to a laboratory in Bengaluru and also collected water samples for testing. The place where sewage water was flowing into the lake was emanating foul smell. https://starofmysore.com/fish-death-continues-at-kukkarahalli-lake/ (15 April 2018)
Even as the fishes are dying at Kukkarahalli Lake reportedly due to overpopulation, Electoral Officer allowed fishing in the lake. Karnataka State Co-operative Fisheries Federation (KCFF) has the right for fishing but due to lack of cooperation between the University of Mysore and the Federation, fishing has been stopped in the lake for the last few months. As a result, the population and size of the fish started increasing. The University authorities claimed that since the Model Code of Conduct was in place (for Karnataka state elections), they could not call for fresh tenders.
According to Prof. K.M. Jayaramaiah, Non-official Member, Karnataka Tank Conservation and Development Authority, waste water from cow sheds and houses of Paduvarahalli flowing through open drains collect at shallow places at the junction of Hunsur Road and north bund of the lake. This polluted water was entering the Lake through drains located at north bund killing fish by reducing the oxygen level in the lake water. https://starofmysore.com/fish-death-at-kukkarahalli-lake-ec-permits-fishing/ (28 April 2018)
1000 fish die in Kalkere lake, residents blame sewage In Sept. 2018, close to 1000 fish died in Kalkere lake near Horamavu. While residents of the locality pointed to sewage flow and poor maintenance of the water body by the Bruhat Bengaluru Mahanagara Palike (BBMP), the civic agency attributed the fish deaths to abrupt fall in oxygen levels in the lake.
Residents said the lake, spread over 105 acres, and received polluted water from surrounding areas over the last few months. They also said that they witness frothing like in Bellandur and Varthur lakes. BBMP officials said Rs 18 crore has been allocated for development on Kalkere lake and work will begin soon. https://timesofindia.indiatimes.com/city/bengaluru/1k-fish-die-in-kalkere-lake-residents-blame-sewage/articleshow/66002127.cms (29 Sept. 2018)
Fish, snails found dead in thousands at Bengaluru’s Madiwala Lake On Oct. 4 morning thousands of dead fish and snails were found floating on the banks of the Madiwala Lake. According to the residents of Madiwala who first noticed the bodies the rising pollution of Karnataka’s water bodies seems to have led to this disaster.
A similar incident was reported from the Valankulam water tank in Tamil Nadu’s Coimbatore earlier this year where hundreds of dead fish were found floating on the tank’s surface one morning. Locals alleged that toxic discharge into the water tank from nearby textile dyeing units led to the deaths. Even in Mumbai, in Sept. 2017, scores of dead fish washed ashore Mumbai’s beaches in the aftermath of the Ganesh Chaturthi festival where idols made of Plaster of Paris (PoP) were immersed into the Arabian Sea.
Despite activists condemning civic bodies for their failure to act against those brazenly destroying our marine ecosystems, no legislative measures have been taken to avoid the decimation of water bodies as clearly visible in the case of Bengaluru’s own Bellandur and Varthur lakes. https://www.timesnownews.com/mirror-now/civic-issues/article/bengaluru-madiwala-lake-bellandur-varthur-dead-fish-snails-water-pollution-marine-life/294412 (5 Oct. 2018)
As per another report, the incident exposed the pathetic condition of the water body. Harsha Vardhan, in-charge Deputy Conservator of Forests, Bengaluru said that since the lake was full of rainwater and the drains are overflowing, the untreated water gushed into the lakes resulting in the death of the fish and snails.
The forest officials said that the lake was earlier being maintained by the Karnataka Lake Conservation and Development Authority (KLCDA) in coordination with the forest department. But after KLCDA was disbanded, the work and funds were yet to be transferred to the forest department. The Minor Irrigation Department, which was in charge of all lakes has also not acted. https://www.deccanherald.com/city/sewage-inflow-kills-fish-696431.html (6 Oct. 2018)
According to Vaman Acharya, former chairman of the State PCB, the fish in lakes normally die due to the lack of oxygen caused by the mixing of drainage water into the lake, but the death of snails were mysterious. A senior official of the department told that prolonged contamination of the lake water has endangered the marine life. Due to heavy rains, the dirty water has also been pushed into the lake which has further led to this situation where the marine life is near to extinction. https://www.timesnownews.com/mirror-now/in-focus/article/bengaluru-thousands-of-snails-and-fishes-found-dead-in-madivala-lake-experts-call-deaths-mysterious/295133 (6 Oct. 2018)
Similarly on Nov 30, thousands of fish have died in the Doodhganga river at Karadaga village, Chikkodi taluk, Karnataka in the past week due to the release of chemical effluents by Maharashtra-based sugar factories, Jawahar Cooperative Sugars and Shahu Cooperative Sugars in Kolhapur district.. https://timesofindia.indiatimes.com/city/hubballi/fish-kill-after-sugar-factories-release-chemical-effluents-to-doodhganga-river/articleshow/61870745.cms (30 Nov. 2018)
Andhra Pradesh Thousands of rare fish species found dead Thousands of fish belonging to Rhinomugil corsula, Salmostana and Ompak species and some amphibians, including Balloon frog, were found dead in the Bheemuni Kolanu in Nallamala forest region. The death of large number of fish species was attributed to pollution of the water body with the disposal of adulterated oils, left-over food stuff and plastic covers in it by devotees travelling on foot to Srisailam.
The devotees cook food on the banks of the pond and carelessly discard the left-over items. The rare fish species that were found dead were first discovered in 1822 and 1863. More devotees belonging to Maharashtra and Karnataka were likely to reach Srisailam by foot in another 18 days posing greater risk to aquatic species in the pond. https://www.thehansindia.com/posts/index/Andhra-Pradesh/2018-03-01/Thousands-of-rare-fish-species-found-dead/362351 (1 March 2018)
Telangana 23 Lakh Fish Die Due to Pharma Pollutants in Lake Nearly 23 lakh fish died in Gandigudem Lake on Oct. 4, allegedly due to chemical effluents released by pharmaceutical companies located in the Kazipally Industrial Area. The police registered a case against five pharma companies found guilty of causing pollution under section 277 (fouling water of public spring or reservoir) and 278 (making the atmosphere noxious to health) of IPC.
There was a precedent to fish dying in lakes around Hyderabad due to pollutants in the water. Earlier in May 2017, 30,000 fish were found dead in Rampally Lake, located 30 km from Hyderabad. In same month, around 4 lakh fish were found floating in Shamirpet Lake and over 20,000 fish died in Medchal. https://www.news18.com/news/india/23-lakh-fish-die-due-to-pharma-pollutants-in-telangana-lake-1538277.html (6 Oct. 2017)
The pollution in the lakes in Telangana continued unabated. The lake, located in Annaram village, had nearly 70,000 fish, and most of them were found dead in Oct. 2017, reportedly owing to untreated sewage being let into the waterbody, and also due to the municipal dump alongside the lake.
Local residents told media that a day before the incident, an earthmover pushed the medical garbage pile into the lake. Shockingly, this is the third such incident happening in the state within two months. Recently, nearly 2 lakh fish were dead, after chemical effluents were released into the Gandigudem lake in Bollarum, Hyderabad by pharmaceutical companies. The fishermen suffered a loss of nearly Rs 2 crore. Earlier in September, hundreds of fish were found dead in Pasumamula Lake in Abdullapurmet, Hyderabad incurring a loss of Rs 60 lakh to the fisheries society. https://www.thenewsminute.com/article/telangana-lake-becomes-graveyard-70000-fish-thanks-sewage-medical-waste-70842 (31 Oct. 2017)
Bangladesh Dead fish in Halda river pose danger to livelihoods, biodiversity Hundreds of dead fish of different species, and other aquatic animals were found floating in the river Halda in June 2018 due to rise in ammonia level in water. The dead fish were posing a serious threat to the aquatic biodiversity of Bangladesh’s largest natural breeding ground for carp.
Locals said the water of Halda River turned pitch-black on June 20, spreading the rotten stench of dead fish. The locals formed a human chain at Madunaghat area on June 23, demanding that the river be saved from industrial pollution. As per Halda River Research Laboratory of Chittagong University, 20 species of fish, including Mola carplet (Amblypharyngodon mola), 5 species of prawn, Mozambique Tilapia (Oreochromis mossambicus), Aer (Sperata aor), Rohu (Labeo rohita) Catla (Catla catla), Mrigel carp (Cirrhinus mrigala), Kalbaus (Labeo calbasu) Kuchiya (eel-type fish) were found floating in the river.
The noted Halda river researcher Prof Dr Manzoorul Kibria said the levels of dissolved oxygen fell sharply and the ammonia went up hundred times the tolerance level due to pollution. Chittagong District Fisheries Officer Mominul Haque said they had inspected different points of the river for three consecutive days and witnessed different species of fish like major carps, prawns, eels, Tilapia, Rohu, and Aer floating in the river.
Originating in Khagrachari’s Ramgarh upazila, the 107km-long river passes through Hathazari and Raozan upazilas before merging into the Karnaphuli River. During April-May every year, different species of carp fish start migrating to the spawning ground of the Halda from rivers like Karnaphuli, Matamuhuri, and Sangu. https://www.dhakatribune.com/bangladesh/nation/2018/06/24/dead-fish-in-halda-river-pose-danger-to-livelihoods-biodiversity (24 June 2018)
Pakistan Hundreds of dead fish wash ashore on Karachi’s Sea View beach A large number of dead sea creatures surfaced along Karachi’s Sea View beach with experts believing that they died owing to an illness or oil spill. The death of marine life was a cause for concern for local fishermen who are dependent on them for their sustenance. Citizens said that that the maritime movement of ships to Karachi’s ports and shore, along with poisonous chemical waste and diesel was a major reason behind the incident.
Experts believe that incidents such as this occur every year as the local authorities have installed a sewage line in the sea. Moreover, the disposal of waste into the sea is also a contributing factor in the loss of marine life. https://tribune.com.pk/story/1804722/1-hundreds-dead-fish-wash-ashore-karachis-sea-view-beach/ (16 Sept. 2018)
In Conclusion The narration of these numerous fish kill incidents in India and a couple from South Asian neighbours show that the fish kill happens in both monsoon and non monsoon months.
Secondly, every year numerous such incidents happen, but the culprits are rarely caught and held accountable, the only exception being the Punjab fish kill of May 2018 where it was difficult to allow the culprits go scot free. Thirdly, it’s clear that thousands of poor people get adversely affected by each such incident, but there is never any compensation for them.
In fact, there is rarely a credible report put together to narrate the full facts. The root cause of the contamination of water bodies in all such cases, is rarely tackled. In fact, we do not know if any one is even putting together a comprehensive account of all such incidents across the state or country and try to find a solution or way forward. Long way to go for the fish and other riverine biodiversity and those dependent on them.
