Zhongke Ecology is a high -tech enterprise focusing on the protection and repair of water ecology. Proliferation release is one of the company's protection methods. At present, Zhongke Ecology operates dozens of fish proliferation stations in the 7 major watersheds and more than 20 provinces and cities across the country. About 20 million fish fry each year is released into rivers and lakes in many places across the country. Behind this, a group of people carefully cared for the elves in these water.

Research and breeding technology, they customize the "exclusive suite" for fish

Proliferation release activity site.

On June 5th, the World Environment Day, the release point of the Dadu River, Heima Township, Ganluo County, Sichuan Province, thousands of miles away from Wuhan. With a order order, the staff opened a oxygen bag containing a small fish, along 8 The slider vertical of the river surface, more than 300,000 tails of lack of abdomen fish, long kiss -kissing fish and other rare fish seedlings jumped into the river water, a splashing water seemed to be telling the joy of returning home. These small fish fry comes from the Chinese science ecology.

Entering the midsummer, in the Dadu River and the Jinsha River, many such proliferation and release activities are densely developed.

Proliferation release activity.

Proliferation and release, that is, directly put the eggs, larvae or adults of fishery creatures directly into natural waters such as rivers, lakes, and reservoirs to restore or increase the number of populations, improve and optimize the community structure in the waters. Relevant national laws stipulate that the owners of the wading engineering must implement the responsibility of ecological environmental protection and continue to carry out proliferation and release activities.

According to Tan Gang, the scientific research director of Ecological Fish China Science and Technology, the process of proliferation and release is divided into three links: "raising, putting, and measurement". In order to ensure the purity of the species gene, the fish that proliferates flow must be a wild parent generation. Most of the rivers have their own indigenous species, and they can only go to the local collection.

Naked alien pupae is a species on the sporadic tourism in the middle of the Jinsha River. The amount of fish resources is very scarce. Tan Gang recalled: "When I first received a naked alien 鳔 鮀 鮀 in 2020, I haven't seen this kind of fish."

Naked 鮀 鳔.

After obtaining a franchise certificate, Zhang Yunhai, the person in charge, led the scientific research team to conduct several special investigations in the Dadu River, Yazhen River, and Jinsha River respectively. In 2020, the team collected 6 live naked alien pour in the Jinsha River Basin. Alas. Zhang Yunhai said: "Sometimes it is collected in a month or two, and some river sections still have to go through the mountains, which is very difficult."

The traditional circular water workshop is used to domesticate naked oscoropia, and the domestic fish domestication is easily infected with small melon insect disease. Zhang Yunhai said: "The breeding of rare fish needs to be carried out in the customized 'exclusive suite'. To this end, we have developed a set of sets of sets of sets of sets of sets of sets ofments Small circulating water system. "The problem of living is solved, and the problem of eating is equally important. "It is easy to infect pests and insect pests with wild fish and insects. We insist on using artificially cultivated bait, without germs and parasites."

Flowers are producing.

After difficulties, in April 2021, the first batch of artificially reproduced naked and different in China was born. Beginning in 2010, the protection of ecological refined aquatic creatures in China has currently owned more than 70,000 tailfish pro -pro -based.

For more than ten years, through the technical cooperation with many universities and scientific research institutes, the Chinese science ecosystem has gradually broken through and mastered more than 100 rare fish domestication breeding techniques, including heavy mouth cracking fish, long pouring, carmine, etc. Plant national secondary protective fish.

The requirements of the release phase are equally strict. Under the supervision and guidance of the competent fishery department, the types, quantities, and specifications of the selection of fish must be bred according to the requirements of the environmental impact assessment of the wading project. After species identification, wild chemical training, inspection and quarantine, and labeling, water inlet body is put. After the release, scientific researchers will also patrol and monitor in the river section regularly to check the survival status and population of the fry, and evaluate the effect of the fish.

Create a cunning fishway, they help the small fish "jump dragon gate"

29 -year -old Qiu Chenghao is the manager of the Fish Technology Department of Ecological Technology Company, Yike Jie (Wuhan) Ecological Subsidians. His work is "the fish who helps the fish on the back of the current". "A sense of accomplishment" for your career.

Proliferation release activity.

According to reports, for the maximum reduction of the impact of the bargaining dam on the ecological environment, especially the number and living habits of the original waterfish population and the living habits of the original waterfish population, in addition to proliferation and release, sometimes it is necessary to carry out artificial fish.

The research design and operation of Yikojie has engaged in fish facilities and equipment. Wu Jianjun, general manager of the company, introduced that domestic fish in China are mainly divided into three forms: fish roads, raising fish machines, and fish collectives.

Yu Road is like a canal, which is mainly used in low dams. In the lower reaches of the dam, the imports of fish roads are mostly arranged on the shore where the water flow is smooth and there is a certain depth of water. In order to ensure that the fish can swim, the slope of the fishway should not be too large. "Two or three -meter -wide fish roads are like Panshan Highway. Sometimes the height difference between the dam body is only 50 meters, but we have to repair 500 meters or even 1,000 meters." Wu Jianjun said. Fish Road.

"Road" is repaired, how can I notify the fish? In addition to the bait guidance, the underwater at the entrance of the fishway is also equipped with LED -lure fish lamps, barriers to fish, etc. The electric grille will send out the pulse signal without harm to the fish to guide the fish group. There are artificial simulated bionic water flow in the fishway, and the flow velocity and flow are scientifically calculated. I was afraid that the fish were too tired, and the fishway was also equipped with a partition for them to rest.

The raising machine is mainly used in Gaoba. Put a fish -like fishing bucket similar to the underwater under the dam to concentrate the fish by guiding. After reaching a certain number, the fish is transported to the end of the reservoir through the vehicle. The principle of fish collecting boats is similar. It attracts the fish group into the collection device through the way of dragging the net or artificial water flow. In the case of better fish -losing effect, these methods can make the dam rate of more than 90%of the dams of fish.

The Lancang River Huangdeng Hydropower Station.

During the operation of the raising fish machine and collecting fish system, the staff will choose some of the fish individuals collected and label before they release. Qiu Chenghao said excitedly: "In recent years, we caught during the investigation in the reservoir area. Some of the fish that have been marked before have also been caught the marking fish that we flow the stations of our proliferation station, which proves that the protection of the fish has achieved remarkable results. "

After the end of the fishing season from March to July, Qiu Chenghao devoted new research. He told reporters that the company's newly developed fish facility intelligent monitoring system plans to produce sample machines within the year, which can achieve "fish face recognition". How many quantities, which variety, and what kind of fish have passed the fish system, and the underwater camera can achieve automatic statistics as long as it is swept.

Laying artificial fish nests, they build a "bed production" for fish

Due to the changes in water flow and depth, some fish have changed in the original habitat and spawning ground in the upper reaches of the river. Zhongke ecology must not only help the fish through the dam, but also build a new and more suitable spawning environment for them.

The staff is scoring the specifications.

Li Hongtao is the head of the Ecological Monitoring and Evaluation of Zhongke. His department is mainly engaged in ecological monitoring and repair of fish habitat. "Just like doctors seeing a doctor, there is a problem with the health of the river in the river. We have to go to the diagnosis and give a repair plan." Playing artificial fish nests is one of the important ways to repair the river environment and repair the eggs for fish repair.

The staff checked the development of fish.

据了解，鱼类大概有3种产卵方式：漂流卵，如四大家鱼，它们的卵会随着水流漂浮；黏沉性卵，如黄颡鱼，它们的卵会沉到河床上；黏Gortar eggs, such as carp, catfish, etc., their eggs will stick to water plants or stones. Different eggs are used to choose different methods to help them realize natural resource proliferation.

Light yellow particles are fish eggs attached to artificial fish nests.

Protecting sticky ovaries mainly use artificial fish nests. The staff first built a 2 -meter multiplier and 2 -meter square frame with a large bowl of bamboo poles. In the framework, a slightly thin bamboo pole is divided into small grids. Palm leaves are hung on the bamboo pole and fixed. it is done. Fish nests are generally laid in a quiet stream area in the near -shore. This environment is not only conducive to fish spawning, but also rich in natural bait. Palm blades are drifting upside down in the water, just like water plants in nature, fish will produce eggs on palm leaves.

Small white particles are fish eggs attached to the artificial fish nest.

Protecting sticky eggs is to throw stones, old tires and other materials in the water, and build artificial fish reefs on the bottom of the water. After the water body becomes complicated, fish eggs and small fish are not easy to be captured.

The research on the rare and unique fish habitat protection and reconstruction project of the upper reaches of the agricultural and rural areas hosted by Li Hongtao is set up in the waters of the waters of the Zhiba area, the Yangtze River Jiangjin River section, and the Chishui City section of Chishui River. Demonstration of fish habitat restoration and reconstruction.

The results showed that the amount of fish nests in the three demonstration waters in the upper reaches of the Yangtze River reached 1.103 billion, 567 million, and 908 million capsules, respectively. Artificial fish nest cloths can proliferate 3750.02 million, 96.705 million, and 24.861 million fish fry, respectively.

The staff count the measuring fish eggs.

Running in the wild all year round, these people who protect the fish are very hard, but almost everyone thinks that the job is "very meaningful"!

It often fights overnight to carry out fish release activities, but Zhang Yunhai is very excited, because now there are more people participating in species protection, and everyone's awareness of protecting the ecology is getting stronger and stronger.

Qiu Chenghao's happiest is the moment when the fishing fights rose from the water. Sometimes there were thousands of fish at one time, and all of them were big and fat. He knew that the ecology was gradually recovering.

The artificial fish nest floated on the water.

Li Hongtao hopes to master the orderly and effective recovery data of natural species during the ten years of fishing in the Yangtze River. He said that protecting the diversity of species is also protecting humans! (The picture of this article is drawn by the Chinese science ecology)
