Chinese paddlefish
A giant freshwater predator from China that is now extinct.
The Chinese paddlefish was a massive fish native to the Yangtze River basin. It vanished due to dam construction and overfishing, with the last confirmed sighting in 2003.
- Last seen alive in January 2003 near Yibin.
- Gezhouba Dam built in 1981 blocked spawning migrations.
- Could grow up to 7 metres long and weigh 500 kg.
- Used electroreception to hunt fish and crustaceans.
- Declared extinct by IUCN in July 2022.
What it is
This extinct fish possessed a distinctive elongated snout resembling a paddle, which made up to one-third of its total body length. Its body lacked scales except for small ones near the tail, and it featured a grey back with a white belly. The dorsal and anal fins were positioned far toward the rear. It could reach lengths of seven metres, making it one of the largest freshwater species ever recorded. Unlike its American relative, it had sharp, inward-curving teeth fused into the jawbone rather than filter-feeding structures.
Where it lives
Native to the Yangtze and Yellow River systems in China, this species also inhabited the adjacent East China Sea and Yellow Sea. Juveniles migrated downstream to brackish coastal waters before returning to freshwater as adults. Adults congregated in the lower Jinsha River section near Yibin for spawning. Historical records indicate presence in the Qiantang and Yong rivers during spring tides, though populations declined significantly in the Yellow River by the 1960s.
How it lives
Adults were solitary, strong swimmers occupying mid-water layers. They used electroreception via ampullae on their rostrum to detect prey electric fields. Diet consisted mainly of anchovies, cyprinids, gobies, catfish, flounders, shrimp, and crabs. Jaws could protrude to seize food. Young fish grew rapidly, reaching maturity around five to six years old. Females likely spawned every other year, producing sticky eggs that sank to attach to riverbed stones.
Breeding and life cycle
Spawning occurred in spring, typically between March and April, in rapid, shallow waters with shingly or muddy bottoms. Males matured at five years, females at six. A single female carried over 100,000 eggs roughly 2.7 mm across. After fertilization, eggs settled on the substrate. Juveniles then migrated downriver to coastal areas for several months before returning upstream to join adult populations.
Fish and people
Fishing for this species dates back centuries, with annual harvests reaching 25 tons in the 1970s. It was consumed as food, though large size made it difficult to handle. Attempts to breed them in captivity failed due to rarity and stress. The last known individual, a female caught in 2003, died after brief tagging efforts. Cultural artifacts like Jinsha site gold belts suggest historical significance, but modern exploitation contributed heavily to its demise.
Status and threats
Listed as critically endangered since the 1990s, the species was declared extinct in 2019. The Gezhouba Dam, completed in 1981, blocked migration routes essential for reproduction, fragmenting the population. Overfishing compounded these effects, removing mature adults before they could replace themselves. Functionally extinct by 1993, no verified sightings occurred after 2003. IUCN formally updated status to extinct in July 2022 following comprehensive surveys confirming absence.
Questions people ask about Chinese paddlefish
Why did the Chinese paddlefish go extinct?
Construction of the Gezhouba Dam in 1981 blocked access to upstream spawning grounds, preventing reproduction. Combined with heavy overfishing throughout the 20th century, the population collapsed and could not recover, leading to extinction by 2010.
How big did Chinese paddlefish get?
They reached lengths of up to seven metres and weights of approximately 500 kilograms. The last confirmed specimen measured 3.63 metres and weighed 200 kilograms. Estimates vary, but they were among the largest freshwater fish ever recorded.
What did Chinese paddlefish eat?
Unlike filter-feeding relatives, they were predators eating small to medium fish like anchovies and cyprinids, plus crustaceans. They used electroreception sensors on their snout to locate prey in murky water and protruded their jaws to capture it.
Where did Chinese paddlefish live?
They inhabited the Yangtze and Yellow River basins in China. Juveniles migrated to coastal seas for growth before returning to freshwater. Adults spawned in specific sections of the upper Yangtze, particularly near Yibin and Chongqing.
