The finless porpoise, a vital species in the Yangtze River, face multiple threats due to habitat degradation and human activity. Amidst conservation initiatives, including a fishing ban, there are signs of recovery, prompting hope for the species' future.

Conservation Efforts for China's Finless Porpoise Show Promise Despite Challenges
Chinese scientists are striving to rescue the critically endangered finless porpoise while implementing stringent fishing bans and addressing environmental threats.
Chinese researchers are intensively working to save the finless porpoise, a species hanging by a thread in the Yangtze River ecosystem. At the Institute of Hydrobiology in Wuhan, notable wildlife specialists emphasize the urgency of their mission, particularly following the extinction of the baiji river dolphin and paddle fish in recent decades. As the last remaining top-level predator in its river habitat, the porpoise's health is considered a key indicator of the entire environment's wellbeing.
In an effort to protect the endangered species, a comprehensive fishing ban has been enforced along the Yangtze River and its surrounding areas—an initiative conceived by Professor Cao Wenxuan of the Chinese Academy of Sciences in 2006. Following years of advocacy, the ban was finally implemented, leading to potential prison sentences for those who violate it. The stringent measures have raised distress among local fishermen, with over 220,000 individuals losing their livelihoods.
Currently, an estimated 1,200 finless porpoises survive in the wild, a count that continues to fluctuate as scientists strive to study their behaviors both in captivity and the wild. Observations suggest that, despite their critical status, these porpoises show remarkable resilience, managing to thrive where other aquatic species could not. Other significant infrastructure projects, such as the Three Gorges Dam, which was completed in 2006, have introduced complex challenges, affecting the food chain that sustains the porpoises.
Environmental advocates like Wang Ding from the International Union for Conservation of Nature (IUCN) are working tirelessly to ensure a healthier future for the Yangtze's ecosystem. While the dam has managed to control annual flooding, it has simultaneously hindered the reproduction of various fish species historically found in the river.
Much needed positive changes have emerged through community involvement and self-initiated conservation efforts, as evidenced by local conservationist Yang He, who documents porpoise sightings and aids authorities in creating safe environments for the animals.
Encouragingly, the numbers of finless porpoises have improved, rising nearly 25% over recent years following the implementation of fishing bans and factory relocations, which have led to enhanced water quality in the river. Scientists view this increase as a reflection of overall ecosystem health, promoting optimism about the sustainable future of the finless porpoise.
As conservationists continue their commitment, the burgeoning population of finless porpoises is seen not just as a success story of saving a species, but as a critical element in the revival of an entire ecosystem.
