The teammates on the side recorded the dolphin's location, behavioral characteristics and other information with pen and paper. .

After photographing the dolphins, Brother Lin skillfully measured the temperature and depth of the seawater with instruments and took samples.

　　[Explanation] Lin Sange is a fisherman born and raised in Sanniang Bay. His other identity is a member of the scientific research team (hereinafter referred to as the "research team") of the Chinese White Dolphin Research, Protection and Life Education Center in Beibu Gulf, Qinzhou City.

Professor Pan Wenshi, a leading figure in Chinese biology, is the initiator and leader of the team, and Lin Sange has worked in the team for more than ten years.

　　[Concurrent] Zhao Yi, director and researcher of Beijing Pan Wenshi Biodiversity Research Center:

　　Said to be a fisherman, he is basically at least half an expert now. He is very professional in the use of these equipment, such as this GPS, camera, video camera, recorder, including some records of dolphins, tide conditions, and weather conditions.

　　[Same period] Lin Sange, a fisherman from Sanniang Bay, Qinzhou, Guangxi:

　　There are more dolphins and more tourists, which brings a lot of benefits to the villagers, so the villagers have a lot of income, and the villagers' lives are getting better year by year, which makes us feel that protecting dolphins is good for the society and for our villagers. the best.

　　[Explanation] It is during the fishing season in the South China Sea (including Beibu Gulf), and Chinese white dolphins foraging and playing can be seen from time to time in the waters of Sanniang Bay, Qinzhou, Guangxi.

For more than ten years, they and their team have guarded the Chinese white dolphins that live in this sea area day after day. White dolphin.

After years of follow-up research, it was found that the population of Chinese white dolphins in the Beibu Gulf waters has increased from less than 100 in 2004 to more than 300, and the age structure is reasonable, and the reproductive population accounts for about 70%.

　　[Concurrent] Zhao Yi, director and researcher of Beijing Pan Wenshi Biodiversity Research Center:

　　(I) have an average of 160 days a year at sea. I just came back from the sea this morning, and each time it takes about four hours. Every time I go to sea, these fishermen friends are in our team. He has been here since he was a child. Pianhai, he saw or got to know dolphins many years earlier than me. Now, every time he goes out to sea, he screams and cheers every time he sees a dolphin.

It just doesn't have the kind of coping with work, it's just very enthusiastic, he said it's like our children.

　　[Commentary] Zhao Yi said that a few years ago, after consulting the scientific research team, the Qinzhou Municipal Government resolutely gave up a shipbuilding project with an investment of billions of yuan, and kept the habitat of the Chinese white dolphin; at the same time, in scientific research Under the team's suggestion, the layout of the entire port industry was adjusted from the shallow sea area in the east to the deep sea area in the west.

Today, a spectacular road into the sea "divides" the waters of Sanniang Bay and Qinzhou Port into two. The east of the road is the habitat of Chinese white dolphins, and the west of the road is the layout of the "oil, coal, gas" multi-headed industrial system. Lingang Industrial Zone.

This sea entry road is like a natural sea city wall, protecting Chinese white dolphins from pollution and intrusion, and is known as the "most beautiful sea entry road".
