In the ancient book "Shan Hai Jing · Dongshan Jing", which is mysterious and unpredictable, there are the following records: "Seven hundred miles in the south of the south, Mencius of Mencius, Muzi Zitong, Duo Tao Li, and its own, and their own, their own, their own, their own, their own, and their own, and their own, their own, their own, and their own, their own, their own, and their own. Multiococcal pad, the beast has many elk. It is mountains, and the wide staff is hundreds of miles. There are water out of the water, the name is Biyang, and many of them. " Alas, this creature recorded by thousands of ancient books has never appeared in human vision after 2003.

On December 11, 2002, in the area of ​​Xiaguan, Nanjing, fishermen mistakenly arrested a 3.3 -meter -long white ravioli. Although they were fully treated by Nanjing fishery administrative staff and scientists, they did not rescue due to excessive injuries. This is also this. This is also this. The last record of the species in the lower reaches of the Yangtze River. On the evening of July 21, 2022, the International Nature and Natural Resources Protection Alliance (IUCN) released the global endangered red catalog update report, which officially announced the extinction. "Common Aquatic Wildlife Idential Manual in Nanjing" includes the last precious picture of the last -hand species that has lived on the earth for hundreds of millions of years ...

In recent years, the Yangtze River Protection Action has attracted much attention, and the diversity of aquatic animals is one of the important indicators reflecting the quality of the Yangtze River. However, due to the hiddenness of the living environment of the aquatic animals, there are fewer related images, which increases difficulty to the ecological protection of the Yangtze River. Based on such "pre -love confession", "Common Aquatic Wildlife Idential Manual in Nanjing" came out. The book was compiled by the Nanjing Institute of Aquatic Sciences and published and published by Nanjing University Press. As the first primary illustration of themes in the province, there are more than 512 pictures of local aquatic animals and 210 kinds of aquatic wild animals that live in Nanjing, including 2 kinds of aquatic mammals, 109 kinds of fish and 19 Smooth crawling. In addition, it also includes more than 60 types of spine -free such as aquatic insects and crustacean software that are inconspicuous but very important in the aquatic ecosystem.

"Not only our common creatures in daily life, but also some of the creatures that are rare and even discovered and recorded for the first time." One of the author of "Nanjing Common Aquatic Wildlife Recognition Handbook", the executive vice president of the Nanjing Qiplom Puffer Protection Association Jiang Meng, the secretary -general, told reporters that, in addition to some precious historical imaging materials, this book relies on the survey of the aquatic biological resource survey of the Nanjing Dashengguan Capital Copper Fish National Aquatic Gender Protection Zone, which has been carried out in recent years. The results, such as the fish resource survey carried out in the Nanjing Yangtze River section in 2021, the first -time pointed tadpole was discovered.

What should I do if I do n’t know the aquatic animals seen in the waters around me? Learn about this undergraduate manual.

Dai Xing Daiyue, fight against time

Fix the spirit of "elf in the water" with hard work

During the early image data collection process, Jiang Meng found that most of the aquatic animal image data had a lack of or not clear enough. As a result, Jiang Meng resolutely determined to set up a imaging survey team to conduct special aquatic biological surveys, samples and shooting in order to write the "Common Aquatic Wildlife Identification Manual in Nanjing". In this way, a camera "Caotai team" from various industries was successfully formed.

The sampling work is heavy and arduous. Early and late returns. It can only sleep for four or five hours a day. "Every time we go to the investigation period, we must go out at more than 5 o'clock, and we must prepare all the equipment one day in advance. After driving on the dock to investigate the ship, we must conduct on the boat and investigators all day long. Investigate sampling work, this state will last for five or six days. "

Aquatic animal living body shooting is a more difficult challenge. After a day -to -day survey and sampling on the boat, Jiang Meng would take the aquatic animals he collected on the day to shoot first. After breeding and treatment, the fish returned to the normal state. Shooting. The scenery of the studio and the fish tank is also quite particular. Jiang Meng will arrange the flash in advance to form a matrix, prepare special custom fish tanks, sediment models, etc., just to maximize the native living environment of each fish. Simulate the native environment of water biological in the studio

Jiang Meng said with a funny way: "Shooting fish is not like shooting people. It is impossible for fish to listen to your arrangement and put a good posture for you." In order to perfectly shoot the swimming state of the fish, Jiang Meng wants to shoot the various angles and postures of the fish. , Action, sometimes you need to take a thousand photos when you take a fish. "When a lot of fish may have to take thousands of sheets, the angle and behavior need to be collected as comprehensively as much as possible."

There are also some special types of fish in the Yangtze River. Only under the stimulating environment of the flowing water can survive, and it will die quickly with the Internet. In order to take the clear living photos of these types of fish, Jiang Meng's image investigation team "moved" the studio to the ship. A set of professional equipment such as fish tanks. "It is more difficult to shoot on the ship. On the one hand, the ship will shake with the water, and on the other hand, it must be filmed while the fish is the most vibrant state. Therefore, the process of shooting is to "race" with time, and may be different in the forefront.

If you are unwilling, stick to the front line

"Guardian" of the Yangtze River Ecological Coastline

The major achievement of the "Common Aquatic Wildlife Identification Manual in Nanjing" is the first time to discover a pointed tadpole, marking a new record species in Nanjing fish discovery, proved that the "ten -year -old fishing forbidden fishing" has achieved certain results, and Nanjing aquatic biological diversity has been restored to recovery Essence When it comes to the opportunity to discover the first time, Jiang Meng responded: "This is an accident." Behind this "accident" is the Jiangmeng and Nanjing Pecgainst Prunts Biological Protection Association have been engaged in the Yangtze River ecological protection and aquatic biological assistance for several years. Job experience accumulation.

"The members of our association come from various corners. The stranded and rescue of porpoons and the new discoveries of fish species have the figures of our association." Jiang Meng said that the discovery of the pointed tip is the labor results of the members of the first -tier association. The Nanjing Prauffian Water Symagonist Association is a non -profit social organization consisting of a group of lovers who are determined to protect the Yangtze River and porpoons. Some of them are transferred fishermen who work on the front line, some are scientific researchers, and some are enthusiasts. They come from all walks of life, but they all use the belief that "protecting the Yangtze River and caring for aquatic creatures".

In the next step, Jiang Meng said that the imaging survey team will "swim" out of Nanjing, follow the Yangtze River, and expand to more aquatic areas including Hongze Lake and Dongting Lake, and become the "guardians" of the Yangtze River Ecological Coastline. "I hope that readers can have a more intuitive and comprehensive understanding and understanding of the diversity and aquatic ecosystem of Nanjing through the manual to improve their awareness of protection of the aquatic creatures in the Yangtze River. The specimens seen in the museum should make them coexist with humans, and always travel freely in the rolling Yangtze River water. "

Bai Yan is the largest aquatic creature in the Yangtze River. The fishermen of the Yangtze River once had a saying: "Jack of salads are ten thousand pounds, and the yellow row is not as big as". It is Bai Yan. Bai Yan likes to inhabit the middle and lower layers of the river, and sometimes enter large lakes. They are fierce top predators and usually move alone to prey on other adult fish.

Selection of fish habitat (hand -painted)

Fish can adapt to different ecological environments, and even fish exist in desert oasis and caves.Due to the differences in the natural conditions of different habitats, the fish also shows extremely high diversity.Some fish like to move in high -soluble oxygen streams, while others prefer the static water bodies of water grass; some can adapt to the salty water in the river mouth waters, and some will repeatedly migrate between the river and the ocean.
