CHON BURI – Local vendors discovered a massive 100-kilogram giant freshwater stingray floating dead near the busy Tha Ruea Phli fish market. The colossal female creature drifted into coastal waters near the pier, astonishing fishermen who rarely encounter the elusive river monster so close to shore.
The morning crowd at the market spotted the lifeless giant bobbing near the docks on Thursday evening. Local workers quickly alerted coastal patrol teams before strong outgoing tides could sweep the enormous animal back out to open sea.
Key Takeaways
- • A rare female giant freshwater stingray measuring 4.3 metres long was found dead at Tha Ruea Phli pier in Chon Buri.
- • Marine biologists and municipal workers retrieved the 100kg carcass, though the exact cause of death remains unexplained.
- • Thai wildlife authorities urge citizens to report stranded marine animals immediately by calling the dedicated 1362 hotline.
Provincial fisheries officers arrived alongside regional teams from Marine and Coastal Resources Office 2 to secure the landing site. Curious onlookers gathered along the concrete pier while municipal workers prepared heavy lifting gear to retrieve the massive aquatic beast.
Official inspection teams confirmed the specimen measured approximately 2.3 metres in disc width and stretched 4.3 metres from snout to tail tip. The team verified the animal was an adult female Chao Phraya giant stingray, known locally as Pla Rahu.
Municipal teams from Chon Buri and Samed subdistricts coordinated transport vehicles to hoist the carcass without inflicting further damage. Officials transported the stingray to a regional facility for biological sampling, formal recording, and scientific burial under strict wildlife protection guidelines.
Endangered River Giants Face Deepening Environmental Perils
Scientists classify the giant freshwater stingray among the heaviest freshwater fish alive, capable of reaching weights above 300 kilograms. Yet river damming, agricultural runoff, and industrial water pollution have destroyed the creature’s core nursery habitats across mainland Southeast Asia.
Dams prevent these bottom-dwelling fish from swimming upstream to reproduce, dividing healthy populations into isolated gene pools. Heavy chemical discharges into river systems further poison food chains, suffocating mollusks and crustaceans that stingrays rely upon for daily survival.
Commercial fishing nets present another deadly threat to river giants navigating coastal estuaries. Rays often get entangled in submerged nylon gillnets, exhausting themselves completely before drowning beneath the murky surface.
According to the IUCN Red List assessment, wild numbers continue downward across Thailand, Cambodia, and Indonesia. Experts warn that losing reproductive adult females deals a catastrophic blow to a species that bears few young over extended breeding cycles.
Stingray’s Death Leaves Marine Biologists Seeking Answers
Pathologists have not yet identified what killed this massive female specimen in coastal Chon Buri waters. The fresh condition of the tissue suggests the animal died recently, either within coastal waters or just upriver in the Bang Pakong basin.
Toxic chemical spills, sudden salinity spikes, and vessel strikes represent common hazards capable of killing mature river rays unexpectedly. Laboratory technicians gathered tissue and water samples to test for lethal toxins, dangerous bacteria, or heavy metal contamination in the coming weeks.
Local conservation groups warn that unusual deaths near shorelines often signal severe chemical imbalances in upstream river channels. Researchers will monitor water quality closely along adjacent coastal estuaries to verify whether nearby fisheries face wider toxic contamination hazards.
Government authorities emphasize that swift public reporting remains vital to saving distressed marine life across coastal provinces. Early intervention gives veterinary crews their best opportunity to rescue injured animals or preserve critical forensic tissue samples before decay begins.
Anyone who spots a stranded, injured, or deceased protected marine animal should immediately call the 1362 hotline. The dedicated emergency dispatch service operates twenty-four hours a day, connecting local callers straight to frontline marine rescue specialists.
