Scientists find more porpoises this year
Print Edition
A total of 165 Yangtze finless porpoises have been visually identified during a scientific expedition along the Yangtze River this year, a significant rise from previous research in 2012.
“There is a notable increase in the population size of the finless porpoise based on our observation,” said Hao Yujiang, head of the research expedition.
On Wednesday, two scientific research vessels docked at a wharf in Wuhan, capital of Hubei Province, concluding a 1,300-kilometer round-trip between Wuhan and Yichang in Hubei.
On November 10, researchers began a scientific expedition to the Yangtze River to study wild finless porpoise and their habits.
The 40-day expedition, organized by the Ministry of Agriculture, was conducted in the main stream of the middle and lower reaches of the Yangtze that spans from Yichang to Shanghai, as well as the river’s largest tributaries and the lakes of Dongting and Boyang.
“Results of the expeditions, including the population of the finless porpoise, are to be made available after sufficient analysis,” Hao said.
An expedition in 2012 found the population of finless porpoises had shrank to about 1,040, about 14 percent less than the number in 2006.
Scientists say insufficient food, illegal fishing tools, water pollution and habitat destruction have been causing the population of finless porpoises to decline.
