Wei Dongqing, Administrative Director of the Hong Kong-Zhuhai-Macau Bridge Administration, mentioned earlier this month that there are more Chinese white dolphins than before.

Recently, the Authority published the results of its report, commissioned by the Chinese Marine Fisheries Research Institute of the China Academy of Fish Sciences on the official website: The average number of Chinese white dolphins in the Bohai waters was 1,167 in the previous special research period from 2005 to 2006, August 2010 Until the beginning of construction of the main bridge body in January 2011, the average number of Chinese white dolphins was 955. In the medium term, construction monitoring from 2015 to 2016. The average number of Chinese white dolphins was 957. In addition, according to the recent monitoring of the Institute of Sea Fisheries South China, the average number of Chinese white dolphins deployed between 2017 and 2018 was 945.

In other words, compared to 2005-06, the number of white dolphins in 2017-18 decreased by about 20% in 13 years.

However, based on the above data, the Administration's proposal reads: "Since the construction of the main bridge project, the distribution of Chinese white dolphins in the Pacific was essentially stable" stressed that there is no construction of Chinese white dolphins due to the construction of the Hong Kong-Zhuhai bridge Macau. It causes serious consequences.

The Office explained that the same investigation team may differ in terms of time, method and scope of research, and the number of Chinese white dolphins included in the study and control is also different. The "Marine Environment Bulletin of Guangdong Province" issued by the Department of Ocean and Fisheries of Guangdong Province shows that the number of Chinese white dolphins has changed significantly, but the number of dolphins for the first time and the frequency of observations increased. In 2016, 258 groups of dolphins and 1890 heads were seen in the area of ​​the White Dolphin Nature Reserve of the Chinese Pearl River Nature Reserve. In 2017, 380 groups of dolphins were observed, totaling 2,180.
