65-498: The district is easily accessed by road from Kampong Cham or Kratié . Though there are numerous smaller roads within the district that cross the border into Vietnam, there is no official international border crossing within the district. The closest official crossing is 44 kilometres (27 mi) southeast of the district capital at Trapeang Phlong in Ponhea Kraek District . Memot town lies on National Highway 7 near

130-639: A cone-shaped wooden stick to drum the side of their canoes, striking their paddles to the surface of the water, jingling their nets, or making calls that sound turkey-like. A pod of dolphins that agrees to work alongside the fisherman will entrap a school of fish in a semicircle, guiding them towards the boat. In return, the dolphins are rewarded with some of the fishers' bycatch . Historically, Irrawaddy River fishers claimed particular dolphins were associated with individual fishing villages and chased fish into their nets. An 1879 report indicated legal claims were frequently brought into native courts by fishers to recover

195-448: A dozen Irrawaddy dolphins were found dead. The discovery of 10 new baby dolphins on the coast of Cambodia was a relief and gave hope that the endangered Irrawaddy dolphins would make a comeback in population. Since the endangerment was evident, 66 guards have been posted on the coast of Cambodia to protect these dolphins, and only two deaths have been reported since these efforts. To make more efforts to keep these animals from going extinct,

260-503: A dozen dead Irrawaddy dolphins were found on the coast of Thailand. These dolphins were said to be dead because of a lack of oxygen. Dolphins are mammals, and unlike other animals that live in the sea, they must come to the surface for air. Many of the dolphins are found dead in the water, and others were washed ashore, said to have been dead for a few days. Also, in the first week of February 2013, as many as four Irrawaddy dolphins were found dead. The Natural Resources and Environment Ministry

325-511: A few groups of dolphins in Brunei Bay seen near the mouths of Temburong and Aloh Besar rivers which are tame and gather around fisherman boats that catch fish during the fishing season from around December to February. It surfaces in a rolling fashion and lifts its tail fluke clear of the water only for a deep dive. Deep dive times range from 30 to 150 seconds to 12 minutes. When 277 group dives were timed (time of disappearance of

390-450: A flipper and occasionally breaching. They are generally found in groups of 2-3 animals, though sometimes as many as 25 individuals have been known to congregate in deep pools. Groups of fewer than six individuals are most common, but sometimes up to 15 dolphins are seen together. Traveling and staying in groups not only enables Irrawaddy dolphins to hunt, but it also creates and maintains social bonds and allows copulation to occur. There are

455-407: A group of scientists took in four Irrawaddy dolphins and provided them with medical care to see how they would survive. However, they found this to be the first case they saw of Irrawaddy dolphins having bacterial infections. The bacterial infection, chorioamnionitis, is common in many marine animals, but when these few dolphins were taken in, the scientists discovered this same bacterial infection for

520-877: A new population was discovered in Guimaras island in the Visayas. In 2015, another new population was discovered in Bago in Negros Occidental , part of Negros island in the Visayas. In 2002, the Marine and Coastal Resources Department was assigned to protect rare aquatic animals such as dolphins, whales, and turtles in Thai territorial waters. To protect the dolphins, patrol vessels ensure boats stay at least 30 m (98 ft) away from dolphins and no chasing of or running through schools of dolphins occurs. Many fishermen on

585-667: A protected area for Irrawaddy dolphins in Santubong and Damai (Kuching Wetland). Furthermore, they plan to establish more beaches in Miri as protected areas for them. The protection measures in the area include prohibition of catching or killing of dolphins and trade in whole or parts of them, and prohibiting the use of gillnets. The government may also start small- and medium-scale research of this species at Sarawak Malaysia University with sponsorship from Sarawak Shell. In 2012 in Vietnam,

650-616: A protected region in a 74 km (46 mi) segment of the Ayeyarwady River between Mingun and Kyaukmyaung and created multiple provisions, as well. Protective measures in the area include mandatory release of entangled dolphins, prohibition of the catching or killing of dolphins and trade in whole or parts of them, and the prohibition of electrofishing and gillnets more than 91 metres (300 ft) long, or spaced less than 180 metres (600 ft) apart. Mercury poisoning and habitat loss from gold-mining dredging operations in

715-500: A result of entanglement in gillnets with large mesh sizes. The majority of reported dolphin deaths in all subpopulations is due to accidental capture and drowning in gillnets and dragnets , and in the Philippines, bottom-set crabnets. In Burma, electrofishing , gold mining , and dam building are also serious and continuing threats. Though most fishers are sympathetic to the dolphins' plight, abandoning their traditional livelihood

He reported this new category of prehistoric sites in the red soil region east of the Mekong in what was then part of Kampong Cham Province and in Vietnam. In 1962, Bernard Philippe Groslier carried out excavations in a circular earthwork near Memot, later called the Groslier site, and named this civilisation "Mimotien". The Memot Circular Earthworks span across

910-553: A share of the fish from the nets of a rival fisher that the plaintiff's dolphin was claimed to have helped fill. Laotians and Cambodians have a common belief that the Irrawaddy dolphins are reincarnations of their ancestors. Some even claim that the dolphins have saved drowning villagers and protected people from attacks by crocodiles. Their beliefs and experiences have led the people of Laos and Cambodia to live peacefully alongside one another for ages. The West Kalimantan people have

975-519: A similar story where the dolphins were naughty children that ate a pot of rice reserved for the shaman, but their mouths scalded and jumped into the water to cool themselves, but later transformed into these dolphins. Buddhist Khmer and Vietnamese fishermen have regarded the Orcaella as a sacred animal. If caught in fishing nets, they release the dolphin from the rest of the catch. In contrast, Muslim Khmer fisherman kill them for food. This has led to

The sex ratio in the district is 94.5%, with significantly more females than males. http://nis.gov.kh/nis/Census2019/Final%20General%20Population%20Census%202019-English.pdf Krati%C3%A9 (city) Kratié ( Khmer : ក្រចេះ , Krâchéh [krɑceh] ), also spelled Kracheh ,

1105-457: Is a slow swimmer, but swimming speeds of 20–25 kilometres per hour (12–16 mph) were reported when dolphins were being chased in a boat. In a year, females can sometimes swim as fast as average of 45 km, males can swim up to average of 100 km. Most Irrawaddy dolphins are shy of boats, not known to bow-ride, and generally dive when alarmed. They are relatively slow moving but can sometimes be seen spyhopping and rolling to one side while waving

1170-582: Is after two years. Lifespan is about 30 years. There are plenty of food items that this dolphin feeds upon. They include fish, crustaceans, and cephalopods. During foraging periods, herds of about 7 dolphins will circle around prey and trap their victim. These prey entrapments occur slightly below the water surface level. Although sometimes called the Irrawaddy river dolphin, it is not a true river dolphin , but an oceanic dolphin that lives in brackish water near coasts, river mouths, and estuaries. It has established subpopulations in freshwater rivers, including

1235-705: Is also covered by the Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (MoU). Several national efforts are resulting in the reduction of threats to local Irrawaddy dolphin subpopulations: Portions of Irrawaddy dolphin habitat in the Sundarbans mangrove forest of Bangladesh are included within 139,700 ha (539 sq mi) of three wildlife sanctuaries , which are part of

1300-551: Is difficult for them. Another identified threat towards the Irrawaddy dolphins was noise pollution from high-speed vessels. This caused the dolphins to dive significantly longer than usual. The Irrawaddy dolphins always changed directions when they encountered these large vessels. In recent years, Laotians and Cambodians developed techniques of using explosives for fishing. The government of Laos has made use of such tactics illegal, but few regulations have been made in neighboring Cambodia, where explosives are sold in local markets and

1365-478: Is from the Latin meaning short-beaked. The Irrawaddy dolphin's colour is grey to dark slate blue, paler underneath, without a distinctive pattern. The dorsal fin is small and rounded behind the middle of the back. The forehead is high and rounded; the beak is lacking. The front of its snout is blunt. The flippers are broad and rounded. The finless porpoise ( Neophocaena phocaenoides ) is similar and has no back fin;

The region within and near the species' range has developed economically; theme parks, casinos, and other entertainment venues that include dolphin shows have increased. In 2002, there were more than 80 dolphinariums in at least nine Asian countries. Collateral deaths of dolphins due to blast fishing were once common in Vietnam and Thailand . In

1495-734: Is listed on both Appendix I and Appendix II of the Convention on the Conservation of Migratory Species of Wild Animals ( CMS ). It is listed on Appendix I as this species has been categorized as being in danger of extinction throughout all or a significant proportion of their range and CMS Parties strive towards strictly protecting these animals, conserving or restoring the places where they live, mitigating obstacles to migration and controlling other factors that might endanger them, as well on Appendix II as it has an unfavourable conservation status or would benefit significantly from international co-operation organized by tailored agreements. The species

1560-584: Is studying artificial breeding options in 2022 to try to save the last herd of Irrawaddy dolphins in Songkhla Lake, which is on the verge of extinction after only 14 were found in the most recent survey. They also intend to list dolphins as a protected species , Thailand's highest level of animal protection. In 2008, the Department of Forestry and Sarawak Forestry Cooperative in Sarawak established

The small town has a population of about 38,215 and lies on the banks of the Mekong River . The city is dominated by a central marketplace surrounded by old, French colonial buildings. Red flowered trees grow in rows along the riverbank. The town includes big islands with white sand beaches within

1690-549: Is the responsibility of individual countries. While some international trade for dolphinarium animals may have occurred, this is unlikely to have ever been a major threat to the species. Some Irrawaddy dolphin populations are classified by the IUCN as critically endangered; in Lao PDR, Cambodia, Viet Nam (Mekong River sub-population), Indonesia (Mahakam River sub-population, Borneo), Myanmar (Ayeyarwady/Irrawaddy River sub-population),

1755-797: Is to support the survival of the remaining population through targeted conservation activities, research, and education. In January 2012, the Cambodian Fisheries Administration, the Commission for Conservation and Development of Mekong River Dolphin Eco-tourism Zone, and WWF signed the Kratie Declaration on the Conservation of the Mekong River Irrawaddy Dolphin, an agreement binding them to work together, and setting out

1820-551: Is to the south. The western border of the district abuts Ponhea Kraek and Dambae districts of Tboung Khmum province. Memot has given its name to a prehistoric culture that lived in the area some 2500 years ago. The Memotian culture is the name given to a series of archaeological sites found in Memot and across the border in Vietnam. The district is home to a number of prehistoric sites which have only recently been studied. In 1959, French archaeologist Louis Malleret first described

1885-605: The Australian snubfin dolphin (of the same genus, Orcaella ), which was not described as a separate species until 2005. It has a slate blue to a slate gray color. Although found in much of the riverine and marine zones of South and Southeast Asia, the only concentrated lagoon populations are found in Chilika Lake in Odisha , India and Songkhla Lake in southern Thailand . One of the earliest recorded descriptions of

1950-491: The Bang Pakong River , Prachinburi Province , have been persuaded by authorities to stop shrimp fishing in a certain area and 30 to 40 fishing boats have been modified so they can offer dolphin sightseeing tours. A total of 65 Irrawaddi dolphins has been found dead along the coast of Trat Province in the past three years. The local fishing industry is blamed for the deaths of the dolphins. In January 2013, over

In 2005, The World Wide Fund For Nature (WWF) established the Cambodian Mekong Dolphin Conservation Project with support from government and local communities. The aim

2145-457: The humpback dolphin ( Sousa chinensis ) is larger, and has a longer beak and a larger dorsal fin. It ranges in weight from 90 to 200 kg (200 to 440 lb) with a length of 2.3 m (7.5 ft) at full maturity. Maximum recorded length is 2.75 m (9.0 ft) of a male in Thailand. The Irrawaddy dolphin is similar to the beluga in appearance, though most closely related to

2210-437: The killer whale . It has a large melon and a blunt, rounded head, and the beak is indistinct. Its dorsal fin , located about two-thirds posterior along the back, is short, blunt, and triangular. Dorsal fin shapes differ from one Irrawaddy dolphin to another. The flippers are long and broad. These dolphins are usually two-toned, with the back and sides being gray to bluish-gray and the belly lighter. Unlike any other dolphin,

2275-462: The Conservation of Freshwater Populations of Irrawaddy dolphins notes that multiple-use protected areas will play a key role for conserving freshwater populations. Protected areas in fresh water could be a particularly effective conservation tool and can facilitate management, due to the fidelity of the species to relatively circumscribed areas. The Action Plan provides details on strategies for mitigating by-catch that includes: The Irrawaddy dolphin

2340-609: The Irrawaddy dolphin from bycatch capture. Gear studies and gear modification to conserve the dolphin species were implemented. The project was completed in 2007. In 2007, the Coral Triangle Initiative, a new multilateral partnership to help safeguard the marine and coastal resources of the Coral Triangle, including the Irrawaddy dolphin subpopulation in Malampaya Sound, was launched. In 2006,

2405-483: The Irrawaddy dolphin was by Sir Richard Owen in 1866 based on a specimen found in 1852, in the harbour of Visakhapatnam on the east coast of India. It is one of two species in its genus. It has sometimes been listed variously in a family containing just itself and in the Monodontidae and Delphinapteridae . Widespread agreement now exists to list it in the family Delphinidae . The species' name brevirostris

2470-495: The Irrawaddy dolphins were frequently chased and confined to a small portion of the tank by the dominant humpbacks. In Chilika Lake , local fishers say when Irrawaddy dolphins and bottlenose dolphins meet in the outer channel, the former get frightened and are forced to return toward the lake. A female or male dolphin will attempt to pursue a mate for about a few minutes. They intertwine facing their bellies together and begin to copulate for 40 seconds. Once copulation has occurred,

2535-563: The Irrawaddy's U-shaped blowhole is on the left of the midline and opens towards the front of the dolphin. Its short beak appears very different from those of other dolphins, and its mouth is known for having 12-19 peg-like teeth on each side of the jaws. Communication is carried out with clicks, creaks, and buzzes at a dominant frequency of about 60  kilohertz, which is thought to be used for echolocation . Bony fish and fish eggs, cephalopods , and crustaceans are taken as food. Observations of captive animals indicate food may be taken into

2600-525: The Mahakam River. The program not only educates and surveys the public, but also monitors the dolphin population and their habitat. A prime example of this is the establishment of patrols in several villages. Some major concern for the population in the Mekong River has arisen due to numerous threats. In the 1970s, many Irrawaddy dolphins were slaughtered for oil, and soon after, intensive fishing practices with explosives and gillnets began. As of now,

2665-506: The Mekong. The stretch of river north of the city is home to a group of rare Irrawaddy dolphins . The dolphins are the town's main tourist attraction.

Irrawaddy dolphins in general however, are IUCN listed as an Endangered species , which applies throughout their whole range. In 2004, CITES transferred the Irrawaddy dolphin from Appendix II to Appendix I , which forbids all commercial trade in species that are threatened with extinction. The UNEP - CMS Action Plan for

2795-427: The areas in which they live. The development of tours and boats has put a large strain on the dolphins. Cutaneous nodules were found present in various vulnerable populations of Irrawaddy dolphins. A more precise estimate of the affected dolphins is six populations. Although the definite fate of this emergent disease is unknown, the species is at risk. The Irrawaddy dolphin's proximity to developing communities makes

2860-547: The death toll for Irrawaddy dolphins is now five in 2015. Usually, Irrawaddy dolphins are found dead with bruises and scars on their body, being killed by illegal poaching, but this Irrawaddy dolphin was found dead because of old age. She is the oldest and largest Irrawaddy dolphin researchers have discovered. The dolphin was 2.5 m (8 ft 2 in) in length and most likely in her late 20s. Myanmar's Department of Fisheries took charge in December 2005, and instituted

2925-462: The dolphin becoming reputed to recognize the local languages of the area and it approaching areas of the Khmer Muslim community with caution. Irrawaddy dolphins are more susceptible to human conflict than most other dolphins that live farther out in the ocean. Drowning in gillnets is the main threat to them throughout their range. Between 1995 and 2001, 38 deaths were reported and 74% died as

2990-711: The dolphins are protected in Cambodia and Laos Democratic Republic. Now, both explosive fishing and use of gillnets is restricted in many of the Irrawaddy dolphin's habitats. Canadian conservationist Ian Baird set up the Lao Community Fisheries and Dolphin Protection Project to study the Irrawaddy dolphins in the Laotian part of the Mekong. Part of this project compensated fishers for the loss of nets damaged to free entangled dolphins. This project

3055-499: The dolphins will break away from each other and set off in different directions. These dolphins are thought to reach sexual maturity at seven to nine years. In the Northern Hemisphere, mating is reported from December to June. Its gestation period is 14 months; cows give birth to a single calf every two to three years. Length is about 1 m (3.3 ft) at birth. Birth weight is about 10 kg (22 lb). Weaning

In Burma, in the upper reaches of the Ayeyarwady River, Irrawaddy dolphins drive fish towards fishers using cast nets in response to acoustic signals from them. The fishermen attempt to gain the attention of the dolphins through various efforts such as using

3185-475: The effort for conservation difficult. Entanglement in fishnets and degradation of habitats are the main threats to Irrawaddy dolphins. Conservation efforts are being made at international and national levels to alleviate these threats. Protection from international trade is provided by the Convention on International Trade in Endangered Species of Wild Fauna and Flora ( CITES ). Enforcement, though,

3250-605: The extinction of this specific species in the Mekong River. The dam builders' proposal is to use explosives to dig out the tons of rock. This will create strong sound waves that could possibly kill the Irrawaddy dolphins due to their highly sensitive hearing structures. In several Asian countries, Irrawaddy dolphins have been captured and trained to perform in public aquaria . Their charismatic appearance and unique behaviors, including spitting water, spyhopping , and fluke-slapping , make them very popular for shows in dolphinaria . The commercial motivation for using this dolphin species

Reading from the north clockwise, Memot shares a border with Preaek Prasab and Snuol districts of Kratié Province to the north. The eastern border of the district is shared with the Vietnamese Province of Bình Phước , while Tây Ninh Province of Vietnam

3445-482: The mouth by suction. Irrawaddy dolphins are capable of squirting streams of water that can reach up to 1.5 metres (4 ft 11 in); this distinct behaviour has been known for herding fish into a general area for hunting. They do this sometimes while spyhopping and during feeding, apparently to expel water ingested during fish capture or possibly to herd fish. Some Irrawaddy dolphins kept in captivity have been trained to do spyhopping on command. The Irrawaddy dolphin

3510-423: The net. Poor fishermen refuse to cut and destroy their nets because it would result in too great of an economic loss to save one Irrawaddy dolphin. In Laos, a dam across the Mekong River is planned. This could threaten the existence of the endangered Irrawaddy dolphins in downstream Cambodia. Laos's government decision is to forge the dam upstream of the core habitat of the Irrawaddy dolphins. This could precipitate

3575-794: The past, the most direct threat was killing them for their oil. The IUCN lists five of the seven subpopulations as endangered , primarily due to drowning in fish nets. For example, the Malampaya population, first discovered and described in 1986, at the time consisted of 77 individuals. Due to anthropogenic activities, this number dwindled to 47 dolphins in 2007. In the Mahakam River in Borneo, 73% of dolphin deaths are related to entanglement in gillnets, due to heavy fishing and boat traffic. The Irrawaddy dolphins in Asia are increasingly threatened by tourist activity, such as large numbers of boats circulating

3640-400: The practice of using fishnets has been abandoned. The practice of using explosives instead has become very popular and led to a steady decline of populations of fish, and especially the dolphins swimming in the area. Although Laotians may not use explosives, they do use nylon gillnets, which pose another large threat to the survival of the Irrawaddy. Some dolphins accidentally become entangled in
