Amidst the ongoing struggle for riverine health, scientists in China are taking significant steps to save the increasingly rare Yangtze finless porpoise. With a total population of only 1,200 remaining in the wild, rigorous efforts including a fishing ban and relocation of chemical factories are yielding hopeful results—showing an increase in both fish populations and porpoise numbers over recent years.

Reviving the Yangtze: The Fight to Save China's Endangered Finless Porpoise
In a critical conservation effort, Chinese scientists focus on preserving the critically endangered Yangtze finless porpoise. Major fishing bans and ecological monitoring are encouraging signs for the future of this remarkable species.
Chinese conservationists are intensifying their efforts to protect the critically endangered Yangtze finless porpoise, a species on the verge of extinction with only about 1,200 individuals left. This initiative is being bolstered by the implementation of a complete 10-year fishing ban in the Yangtze River region, reflecting the pressing need to prevent a repeat of historical extinctions, such as that of the baiji river dolphin and the paddle fish.
Professor Wang Xi from the Institute of Hydrobiology in Wuhan emphasizes the significance of the finless porpoise as the last top-level predator in the river, which serves as an indicator of the overall ecological health of this vital waterway. The decline of previous species in the river has underscored the urgency of current preservation efforts. After an extended, extensive advocacy campaign, the fishing ban finally took effect nearly five years ago and has already led to a marked resurgence in fish populations.
The damming of the Yangtze River, particularly the construction of the Three Gorges Dam, introduced both challenges and opportunities for the finless porpoise. Unlike other large aquatic species that suffered due to obstructed spawning grounds, the porpoises adapted by not migrating upstream. However, the dam has disrupted food sources—affecting fish stocks that the porpoises rely on.
Community involvement is also playing a crucial role in safeguarding the porpoise. Local resident Yang He, an amateur photographer, actively monitors porpoise populations along the river and reports sightings to researchers, aiding conservation efforts. His efforts climaxed in a recent incident where he alerted authorities to a distressed porpoise caught in netting, leading to its rescue.
As a result of these concerted conservation actions, scientists report that finless porpoise numbers have surged by nearly 25% in the past five years, a significant rebound from the bleak statistic of just 3,300 individuals in the 1990s when their decline began. The rise in porpoise populations correlates positively with the overall ecological restoration of the Yangtze River, suggesting that strong, coordinated efforts can indeed halt the looming threat of extinction. As Wang Ding from the International Union for Conservation of Nature wisely states, “We’re saving the finless porpoise to save the Yangtze River,” highlighting an essential truth that prioritizing one species inevitably leads to broader ecological benefits.
