Yuncheng Salt Insurance Center launched the Salt Lake Water System Survey on the 305th day

The brine is a "resident resident" in Yancheng Yancheng.

Although the brine in the salt pond in Yuncheng does not belong to the microorganism, its shape is small and the development value is extremely high. It is a natural advantage species in salt ponds.

Brine (also known as saltwater infected yearworm)

Traal insects, also known as salt water, are a small -sized and low -sized chito animals with high salt resistance. They are classified as the family of nodes, crustacean, gill footal sterilization, nail -free, and salt water. Both the world's coastal and inland salt lakes are distributed.

As a living animal opening bait of juice fish and shrimp, it started to find larvae and apply it in the United States in the early 1950s.

What can brine can be used for?

Experts from Yuncheng College said that the marinat eggs are easy to collect and processed, and can be stored in dry. When used, it is incubated into an unclear larvae for open bait for juvenile fish and shrimp. At the same time, the nutritional value of marine eggs is very high. The newly hatched larvae has a high yolk content, and it is rich in protein and fat.

The bait made of brine wormworm

According to reports, the adults of brine also have high nutrition, with nearly 60%of protein in dry substances, and about 18%of fat. It can also be used as a good bait for adult fish, shrimp, crabs and ornamental fish.

In addition to its important significance for aquaculture, brine worms are good experimental animals in genetic studies such as genetics. They are called the "fruit flies" of the ocean by experts. Pay attention to.

So, what are the characteristics of brine in Yancheng Salt Pond?

According to reports, there is no obvious difference between the morphological characteristics and the salt field brine worms in my country in terms of morphological characteristics. Essence

Yuncheng Yanchi brine has two ways to produce ovarian and ovarian birth, which can breed 6 generations each year. Among the brine groups, the number of male and female individuals is roughly equal, and the change of male and female ratio is roughly between 1.01-1.3. Therefore, the brine in the salt pond in Yuncheng has a slightly more male worm than a female, and has the result of the high yield of brine adults and the low egg yield of brine.

Fishing of brine

According to reports, the salinity is the best environment for the growth of brine for the growth of brine. We also saw the fishingman of the brine in the investigation. They use homemade insect nets, the length of the net is 20 meters, the front mouth is 3 meters wide, and the tail mouth is 1 meter wide (open the tail to put the brine into the bag). I saw the fish that took the net and walked back and forth in the water. Because of the buoyancy of salt water, the baggage was floating on the water.

Different experts have different opinions on the causes of "colorful salt lakes" that we are proud of.

Some experts believe that the formation of "colorful salt lakes" landscape is directly related to brine. Because, whether it is magnesium sulfate or magnesium chloride, it is colorless in the water and does not make the lake red. In the salt pond of Yuncheng, there is a salt -loving green microalgae called Du's salt algae. Under certain conditions, hemoglobin will be produced, and the algae body is red. After a large amount of brine, after eating this algae, the lake will be red.

Other experts believe that the lake becomes reddish caused by organic microorganisms. The expert discovered a red microorganism -wheel worm that rarely seen in salt pond brine. It can be seen under the microscope that there is a circle of halo around the body of the wheel worm, reflecting pink light in the sun, and the shades of the color will also change with the strength of the light.

Wheelworm (one of the food sources of brine)

According to reports, wheel worms are microorganisms smaller than brine, about 0.5mm, and the length of adult brine is about one centimeter, which will devour the wheel worms. few. The wheel worms are widely distributed in various types of light and salted water in lakes, ponds, rivers, and offshore. Due to its extremely fast breeding rate, the production volume is high, it is the bait of most economy aquatic animals. It has great application value in fishery production and is of great significance for the research of ecological structure, function and biological productivity.

When investigating the brine breeding base on the east side of Yanchi, our city proposed that it is necessary to scientifically and reasonably do a good job of developing and utilizing brine worms to maximize ecological and economic value. In the context of "returning salt to the lake", how to give full play to the ecological and economic benefits of brine is worth thinking about.
