Humans have always coexisted with fish and influenced each other's lives. Especially in Qinghai Province on the mainland, Huangyu is one of the main food sources of the local people, and was once known as the "treasure of the plateau". However, in the past half century, due to the impact of human activities, the population of Huangyu has plummeted and is even at risk of extinction.
Now the state has begun to protect the fish, and no one dares to catch them at will, but now it has become a flood.
The treasure of Qinghai Lake
Qinghai Lake, the largest saltwater lake in Northwest China, is known for its unique natural landscapes and precious biological species. Among them, as the "guardian" of Qinghai Lake, Huangyu plays an important role in ecological protection and ecological balance.
Huangyu is a special fish species in Qinghai Lake, with a special and charming appearance. They have a slender body and no scales, and are known as "naked carp". Faced with the harsh natural environment of Qinghai Lake, the Huangyu has adapted to the tremendous pressure of the lake over millions of years of evolution and has become an indispensable part of the lake's ecosystem.
Due to the particularity of the water environment of Qinghai Lake, the Huangyu chose a short migration to complete the critical stage in its life history. Every summer and autumn, they form schools of fish that swim upstream from Qinghai Lake and return to freshwater wetlands along the rivers that flow into the lake to breed. This spectacular migration is breathtaking.
The migratory pattern of the fish is not only related to the living environment, but also closely related to its own reproductive needs. The waters of Qinghai Lake are scarce in nutrients, food is relatively scarce, and the temperature of the lake is low, only 1.2°C all year round. Fish need plenty of food and the right water temperature to grow and reproduce.
The resources around Qinghai Lake are limited, and the fish rely on wetlands that migrate to the riverside to survive and reproduce. During the migration, the fish feed along the way, taking in enough nutrients to meet their reproductive needs, and the nutrient-rich waters of the river provide an ideal recovery period for the small fish.
After spawning, the small fry of the fish will travel down the river and return to Qinghai Lake, where they will reintegrate into the lake's ecosystem. Their journey of life begins at Qinghai Lake, at the edge of Huangyu's iconic wetlands, peaks on a migratory river, and ends in the lake.
The migratory process and reproductive capacity during the life cycle of the fish are essential for maintaining the health of the Qinghai Lake ecosystem. As an important link in the food chain, the fish can regulate the nutrient balance in the water body by feeding on plankton, benthic animals, aquatic plants, etc., and maintain the clarity of water quality and the sustainable ecology of the lake.
The migratory behavior of the fish also has an important impact on the reproduction of other aquatic animals. The eggs laid and the squid provide abundant organic matter to the river, promoting nutrient cycling in the river and increasing the productivity of the water.
Huangyu is not only ecologically significant, but also an important source of protein for the local people, and is one of the characteristic products of Qinghai Province. Among the various specialties of Qinghai Lake, Huangyu is undoubtedly one of the most popular ingredients. Its unique taste and delicious taste have won praise from many tourists and become a highlight of Qinghai Lake tourism.
The population of Huangyu continues to decline, posing a serious challenge to its conservation situation. Human activities have caused irreparable damage to the ecological environment of Qinghai Lake. Irresponsible practices such as illegal fishing and water pollution have put the fish in danger of extinction.
In order to protect this rare species and the prosperity of Qinghai Lake's ecological environment, the government has stepped up its protection efforts and formulated a series of protection policies and regulations. At the same time, publicity and education activities are carried out to raise public awareness of conservation, promote the concept of sustainable development, and strive to maintain the balance and stability of the Qinghai Lake ecosystem.
Huangyu is the precious wealth of Qinghai Lake and an indispensable biological population in our ecological environment. Focusing on the protection of the fish is to protect the home of our survival. Protecting the Huangyu means protecting the clarity and rippling beauty of Qinghai Lake.
The value of the fish
Originating from the Qinghai-Tibet Plateau region of the mainland, the fish mainly lives in Qinghai Lake and the surrounding rivers. In the past history, Huangyu was loved by people for its rich nutrients and unique taste.
Huangyu also plays an important role in many fields such as economy and culture. For example, it is part of the lake ecosystem, which is of great significance for maintaining the regional environmental balance, and it is also one of the local characteristic industries, which promotes local economic development and social stability.
With the development and progress of society, people have gradually realized the importance of natural resources and adopted a series of measures to protect the ecological environment. However, there are still some undesirable behaviors in the fishing activities in the Qinghai Lake area, such as illegal fishing, indiscriminate fishing and killing, which not only damage the ecological environment, but also greatly reduce the survival rate of the fish population.
With the acceleration of industrialization and the acceleration of the construction of hydropower stations, reservoirs and other related facilities, many water flows originally used for the migration and reproduction of Huangyu have been hindered or changed, which greatly limits their growth space and development prospects.
In addition, the irrational development of lakes and the adjustment of land use patterns brought about by urbanization have also threatened this species to varying degrees. On the other hand, a series of problems such as rising temperatures and increasing extreme weather events caused by global climate change have further exacerbated the plight faced by Huangyu.
Climate deterioration will lead to an increase in water temperature, induce the occurrence of various diseases and reduce the immunity of fish, and at the same time, the frequent occurrence of heavy rains and floods will have a negative impact on the stability of the river, making it difficult for the fish to adapt to the new ecological conditions.
As an important part of the plateau ecosystem, the demise of the Huangyu will have a profound impact on the stability and diversity of the entire system.
Secondly, without such a unique resource and cultural symbol, Qinghai Province will also suffer heavy economic losses and social instability, the quality of life of the people will be greatly reduced, and the local cultural inheritance and development will also be in trouble; finally, on a global scale, it will also lose a precious scientific research resource and cultural heritage.
The rescue of the Huangyu in Qinghai Lake
Once upon a time, people living on the shores of Qinghai Lake believed that the "black-backed, red-bellied" fish would bring good luck. It is a cold-water fish with a long growth cycle and delicious flesh, and it is also one of the main food sources for the locals, and with the impact of environmental pollution, climate change and other factors, the Huangyu is facing serious threats and was once regarded as the "giant panda in the water".
It is not easy to completely change the fate of Huangyu. Over the past few decades, there have been attempts to find solutions, such as improving sewage treatment facilities to prevent pollutants from entering the water source. At the same time, the construction of flood control levees can also prevent the siltation of the lake bottom caused by the backflow of river water. These measures have effectively reduced the pressure on the habitat of the fish, allowing it to survive the growing season and reproduce successfully.
With the acceleration of social development, people gradually realize the importance of environmental protection and actively devote themselves to the cause of protecting Huangyu. They disseminate conservation knowledge through various means, encourage everyone to care for nature and save water. With the promotion and support of the government, a series of strict regulations have been introduced, clearly stipulating fishing times and catch weights, with the aim of maintaining biodiversity in the lake area.
Only by strengthening the awareness of environmental protection, establishing and improving relevant laws and regulations, and severely punishing illegal acts, can we effectively curb the trend of endangered fish. At the same time, we should also step up scientific research efforts to explore more sustainable development methods and make greater contributions to the ecological protection of the Qinghai Lake area.
epilogue
The relationship between humans and fish is both a historical tradition and a practical challenge, and only by strengthening the understanding of environmental protection and actively seeking solutions can fishery creatures such as Huangyu be truly cared for and protected. In the long run, we should focus on implementing the concept of sustainable development, deepen the awareness of ecological protection, optimize the system of policies and regulations, and work together to build a world where people and nature coexist in harmony.
Everyone should be a part of the environmental protection action and participate in the protection of the fish and the environment in which they live in their own right. Let's work together to protect this precious treasure of the earth and ensure that it is respected and cherished in the future.
