Introduction to Ning'an Rainbow Trout
Ning'an Rainbow Trout, a specialty of Mudanjiang, Heilongjiang Province. Rainbow Trout is a salmonid fish that is good at jumping and fiercely fighting after being hooked. Residing in lakes and rapids, with bright body colors. There are small black spots on the body and a red band on the side, resembling a rainbow, hence the name "rainbow trout". Ning'an rainbow trout is a geographical indication product for agricultural products.
In the mountains adjacent to the beautiful Jingbo Lake, there is a bay of clear water. The direction of this water flow is not fixed, and it flows sometimes east, sometimes west, sometimes south, and sometimes north throughout the day. Because of this, people call it Zhuanxin Lake. Some people also say that because water rushes out from the bottom of the lake, it should be called a "core drilling lake".
There are also millions of precious cold water fish breeding in Zhuanxin Lake. These fish are blue-green in color, with a spindle shaped body and a dark red rainbow like long bar in the middle, hence the name rainbow trout.Rainbow trout is a member of the Salmonidae family, with two types: one breeds in rivers and grows in the sea. This rainbow trout is a steel headed trout and belongs to the descending type; Another type is the cold water fish that never enters the sea and lives in mountain streams, called the land seal type. The artificially raised rainbow trout is the land seal type. In the 18th century, there was a wild rainbow trout in the streams of the mountains in northern California, USA. After World War II, it was artificially domesticated and became a captive fish.Rainbow trout grow the fastest in water between 16-18 ℃, and they have strict requirements for water quality. The water must be clear and flowing, with gravel at the bottom and no pollution. Because the water in Zhuanxin Lake is warm in winter and cool in summer, and does not freeze even in severe winter, it is abundant in water and fresh in water. After being filtered by underground karst caves, it flows through mountains and rocks like a spring to the ground, forming a mountain lake that is far away from cities without any pollution. Therefore, the water quality of Zhuanxin Lake is most suitable for rainbow trout growth. After more than ten years of breeding, rainbow trout have taken root in Zhuanxin Lake. The Zhuanxin Lake of Bi 1 has become a breeding base for rainbow trout in China. The Zhuanxin Lake Rainbow Trout Breeding Farm was built and put into operation in 1985, with a standard fish pond of 10000 square meters and supporting production, living facilities, feed processing, fish fry hatching and other facilities covering an area of 4.3 million square meters. It is the largest rainbow trout breeding farm in China. In 1990, it won the Silver Award of the Ministry of Agriculture's Spark Plan, with an annual output of 5 million eye eggs, 600000 juvenile fish, 15000 kilograms of fish species, and 100000 kilograms of commercial fish. On the basis of rainbow trout, excellent varieties of cold water fish from abroad have been introduced, such as salmon, golden trout, Dow trout, high white salmon, and salmon, which can provide various excellent varieties of salmon and trout as well as high-quality fish eggs and seedlings to all parts of the country. Zhuanxin Lake has beautiful scenery, beautiful environment, and abundant resources, with 24 species of wild forest frogs and various fish. With superior geographical location and abundant tourism resources, Zhuanxin Lake relies on natural scenery and rainbow trout farms to plan and construct a rainbow trout park. The construction plan for the park has been approved. The construction project includes a central service area (Rainbow Trout Garden Restaurant, Rainbow Trout Fish Exhibition Hall, etc.); Water activity areas (fishing and camping areas, boat docks, water parks, etc.); Leisure vacation villa area, etc; Volcanic lava viewing area; Rainbow trout aquaculture area; Rainbow trout hatching in six major areas, an ecological park integrating tourism, sightseeing, fish tasting, fishing and other functions.Regional Scope
