In the morning, finless porpoises like to appear in the Yangtze River Bridge and Laojiangkou. At noon, finless porpoises are often in the waters of the former site of Xiaguan Power Plant. At night, finless porpoises like to live near Qianzhou Island in the Yangtze River.
In spring, the finless porpoise’s favorite water spot is around Pier 4 in Laoxiaguan, where they chase and show their love and breed their offspring. In summer, the finless porpoise’s favorite activity area is between the Yangtze River Bridge and the Third Yangtze River Bridge. It surfs from the upstream in a cyclic way, and then lurks back from the downstream. Generally, there are few probes. In autumn, finless porpoises like the waters near the outlets of Sancha River, Jinchuan River and Waiqinhuai River, where they hunt and play. In winter, finless porpoises like the waters around Zhongshan Pier best.
On the bank of the Yangtze River in Nanjing, a citizen used his spare time to observe and record the life world of the finless porpoise. This insistence has been unconscious for ten years. He took tens of thousands of photos of finless porpoises’ life and numerous videos, and discovered a set of laws of finless porpoises’ infestation. He not only became one of the most comprehensive folk holders of finless porpoises in Nanjing Yangtze River waters, but also became an expert in finless porpoises observation and a volunteer for finless porpoises protection. He is even known as the living archives of Nanjing finless porpoise, and the stored image materials have attracted the attention of media including CCTV.

I didn’t know the finless porpoise until I saw the big black fish through a telescope.
Wu Jiamin, who is in his fifties, has lived in the old Xiaguan area near the Yangtze River. He is a political engineer of Nanjing Railway Materials Company. In the past, Xiaguan in Nanjing often saw wild animals and plants that were hard to find in the urban area. Wu Jiamin, who likes photography in his spare time, began to pay attention to shooting these things that were still "non-mainstream" at that time.
Talking about his "history of shooting finless porpoises", Wu Jiamin smiled and told Zi Niu journalists that it was purely a coincidence. In the autumn of 2007, as usual, he stood on the balcony of his office and watched the scenery of the Yangtze River Bridge with a telescope. He accidentally found several black things on the river near the pier of the bridge, which caught his attention. "Although I have lived by the river for many years, I have never seen this thing before, so I went to the river to watch it. These black-backed ‘ Big fish ’ What is it? " Wu Jiamin said that when he saw this fish-like thing, he really couldn’t name it. Fortunately, the fishermen who were familiar with the river didn’t know that the animal was called Jiang Zhuzi until they asked. When they came back, it turned out that its scientific name was Yangtze finless porpoise, and its living environment was not optimistic, and its number was decreasing day by day.
Since then, Wu Jiamin began to pay attention to the finless porpoise in the waters of the Yangtze River in Laoxiaguan. Every weekend, he runs on the riverbank line between the Yangtze River Bridge and the Third Bridge. Even he didn’t think that it would take 10 years for this concern to come and go, and he also recorded the finless porpoise for 10 years with his lens.
search
After 10 years of persistence, I have now found out the habits of finless porpoises.
In the past 10 years, Wu Jiamin has traveled all over the Yangtze River in Nanjing, shooting many precious videos and tens of thousands of photos of finless porpoises. Wu Jiamin, riding a motorcycle in the storm, carrying a camera bag and hanging a camera around his neck, stared at the river with familiarity. "Riding a motorcycle to follow the footprints of the finless porpoise along the riverbank, sometimes it takes a whole day to wait, and it is hard to find its beautiful figure. It is very frustrating. Sometimes I accidentally meet a finless porpoise and leap in the river, feeling like a treasure, holding my motorcycle with one foot and my right hand ‘ Pa pa ’ Press the shutter slowly, turn on the camera switch with your left hand, keep scanning the river and take a once-in-a-lifetime scene. " Wu Jiamin excitedly gestured to Zi Niu news reporter the scene when he saw the finless porpoise, and the loss of fruitless search was gone.
In the past 10 years, Wu Jiamin has broken five motorcycles alone, and his trip can basically go around the earth.
"Lao Wu is now an expert on finless porpoises. As long as he wants to see it, he can see it, and he can also photograph it. Others can’t." Master Zhou, a fisherman who has been fishing by the river for many years, told Zi Niu news reporter.
After years of pursuit, Wu Jiamin’s efforts have paid off. He has been able to sum up the law of finless porpoises’ appearance and determine the scope of finless porpoises’ activities according to the climate change and the state along the Yangtze River in Nanjing. "The finless porpoise activity area is mainly concentrated in the lower reaches of Nanjing Xinshengzhou and the upper reaches of Nanjing Yangtze River Bridge." Wu Jiamin told Zi Niu news reporter that it can be determined that there are many finless porpoises between the upstream and downstream of Nanjing Yangtze River Bridge and Nanjing Second Bridge, and there are about 50 finless porpoises in this section.
According to Wu Jiamin’s observation for many years, although there are less than a thousand finless porpoises swimming in the Yangtze River according to the statistics of scientific research institutions, there are about 60 finless porpoises in the waters of the Yangtze River in Nanjing, which can be said to be very rare.
protect
I hope the Yangtze finless porpoise can become a business card of Nanjing.
Following the finless porpoise in the past ten years has also made Wu Jiamin shoot many proud works. For example, at noon on May 19 this year, Wu Jiamin photographed the moment when the finless porpoise jumped out of the river at the Laoxiaguan River in Nanjing, which was the most wonderful. At 7 o’clock in the evening in July this year, he found about 50 finless porpoises chasing upstream in groups of three or five at the riverside pier, which is the most spectacular; On the morning of November 30, 2013, he photographed the finless porpoise chasing wild ducks on Qianzhou Island in the Yangtze River, which was the most interesting … …
In order to better protect the ecological environment of the Yangtze finless porpoise and the Yangtze River basin, in January 2014, the Nanjing Municipal Government proposed to protect the finless porpoise, and in September of that year, the provincial government approved the establishment of the Nanjing Yangtze finless porpoise provincial nature reserve. In the protected area, new docks and port docks will be strictly restricted. At the same time, fishermen in the protected area will gradually withdraw, and finally fishing in the protected area will be completely banned.
Since then, the Nanjing finless porpoise protection association was founded in July 2015 by a social group in the field of wildlife protection registered by the Nanjing Civil Affairs Bureau. Wu Jiamin was one of the six people who founded the association.
"The Yangtze finless porpoise is one of the representative species in Nanjing, and Nanjing is also the only city in the country with wild finless porpoises in the central section of the city. In order to attract more people to pay attention to the Yangtze finless porpoise and its ecological protection, and to expand the visibility and influence of Nanjing Yangtze finless porpoise, I am willing to work together with the association’s finless porpoise protection volunteers to build the Yangtze finless porpoise into an urban species business card in Nanjing. " Wu Jiamin said.
Ten years’ experience
The number of finless porpoises is increasing.
After observing finless porpoises for 10 years, Wu Jiamin told Zi Niu news reporter that his biggest feeling is that finless porpoises are being protected by people more and more. Besides the increasing number, there are fewer and fewer ways for them to be hurt.
"When I first saw finless porpoises, they were only three or five. Later, they counted more than a dozen. In recent years, they have gradually increased to fifty or sixty." Wu Jiamin said that not only the number of finless porpoises is increasing, but also the living environment of finless porpoises is getting better and better with the standardization of management departments and the improvement of environment.
But another problem that can’t be ignored is that the damage to finless porpoises caused by shipping vessels on the Yangtze River can’t be completely avoided at present. "Although the waterway has a fixed route, the finless porpoise may not be able to avoid it, so it can’t avoid being hurt." Wu Jiamin said that he hoped more people would join in protecting the finless porpoise and protecting human friends, and jointly create a harmonious and beautiful ecological home.
unsolved mystery
"On cloudy days, there is a small wind at the starting point on the river, but it can’t be too big, and the probability of finless porpoises is relatively high; In the dry season, with better weather, finless porpoises will also appear … …” Wu Jiamin said that when the black-eared kite fishes, the finless porpoise also preys, and there are often scenes where the black-eared kite and the finless porpoise play together on the river. "finless porpoises may be afraid of heat, especially when the sun is strong, and finless porpoises are rarely seen. In particular, this year, the river surface in Nanjing has been roasted at high temperature for about two months, so it is rare for the public to see its beauty. Where did the Yangtze finless porpoise hide for the summer? This is really a mystery, and I am looking for the answer. " Wu Jiamin said with a smile.
