Enteromorpha is a grass-green algae that generally grows on tidal flats and gravels in mid-tidal zones. Many people may not know much about Enteromorpha, especially the causes of Enteromorpha. Let me introduce to you in detail the knowledge about Enteromorpha Enteromorpha below.

Reasons for the formation of Enteromorpha

Due to global climate change, water eutrophication and other reasons, the green tide outbreak of the large marine alga Enteromorpha has occurred. Large amounts of Enteromorpha enteromorpha float and accumulate on the shore, blocking waterways, destroying marine ecosystems, and seriously threatening the development of coastal fisheries and tourism. Most types of seafood are widely distributed in oceans around the world, and some species can also be found in brackish water or rivers. Enteromorpha is a genus of the green algae Ulvaceae. There are about 40 species, and there are about 11 species in China.

Common species in China include Enteromorpha marginata, Enteromorpha flatis, and Enteromorpha stripes. Most types of seafood are widely distributed in oceans around the world, and some species can also be found in brackish water or rivers. It grows on rocks in the intertidal zone, on the gravel of mud beaches, and sometimes on the algae of large seaweeds. Although its plant body is very slender and looks like green filaments to the naked eye, it is composed of multiple cells. The ecological hazards of Enteromorpha

Although Enteromorpha is non-toxic, like red tides, mass-proliferating Enteromorpha can also block sunlight and affect the growth of seabed algae; dead Enteromorpha will also consume oxygen in seawater. ; Other studies have shown that chemicals secreted by Enteromorpha may also have adverse effects on other marine organisms.

The outbreak of Enteromorpha will also seriously affect the landscape and interfere with tourism and water sports. This is the biggest negative impact that people want to try to eliminate this time. Therefore, foreign countries have called the outbreak of large green algae such as Enteromorpha "green tide" and regarded it as a marine disaster like red tide. In order to appease people's hearts, some experts said that the Enteromorpha Enteromorpha outbreak has no negative impact, which is strictly speaking incorrect.

Fortunately, it is relatively easy to control the outbreak of Enteromorpha. As long as you continue to salvage the green tide, the green tide will naturally subside when the nutrients in the water are almost consumed. In contrast, red tide control is much more difficult. Because of this benefit, scientists hope that large green algae can multiply and suppress the occurrence of red tides, as long as some of them can be salvaged in time before the green tide breaks out. Of course, the most effective way to control it is to prevent seawater from eutrophication and fundamentally cut off the human factors that cause red tides or green tides? However, this is a major difficulty in environmental protection work.

Since mid-June 2008, a large amount of Enteromorpha has drifted from the central waters of the Yellow Sea to the waters near Qingdao. The offshore waters and coasts of Qingdao have encountered a sudden and unprecedented natural disaster of Enteromorpha. Qingdao is the venue for the 2008 Summer Olympics sailing competition. Enteromorpha once affected sailing athletes' training at sea. As of July 5, more than 400,000 tons of Enteromorpha have been cleared by Qingdao Sea and Land. By July 15, more than 1 million tons of Enteromorpha prolifera had been removed. The Qingdao Olympic sailing competition waters and the enteromorpha along the Qingdao coast have basically been cleaned up.

On May 28, 2011, the North Sea Forecast Center of the State Oceanic Administration discovered Enteromorpha enteromorpha on the eastern coast of my country. At that time, a green tide of Enteromorpha Enteromorpha was discovered off the coast of Yancheng, Jiangsu Province (120?29?E-120?35?E, 33?52?N-34?20?N), covering an area of ??about 6.8 square kilometers and a distribution area of ??about 340 square kilometers. . Subsequently, the coverage area and distribution area of ??Enteromorpha green tide continued to expand, and drifted northward with the sea current and wind direction.

In July 2011, large areas of Enteromorpha entered the coastal waters of Shandong such as Qingdao, Yantai, Weihai, and Rizhao. Thick Enteromorpha is accumulated on some beaches, and the bathing beaches are shaped like prairie, which has a negative impact on coastal aquaculture and tourism. Since July 6, 2011, enteromorpha has appeared in varying degrees on the beaches of various bathing beaches along the coasts of Qingdao, Weihai, and Rizhao. Shandong coastal areas are organizing relevant departments to carry out enteromorpha salvage and cleanup work. According to on-site conditions, the scale of Enteromorpha along the coast today has increased significantly compared with the previous two days. Enteromorpha can be seen everywhere in the shallow sea, and most of the Enteromorpha has landed.

Enteromorpha enteromorpha has landed in major bathhouses in Qingdao. Qingdao Bathhouse personnel have organized personnel and large equipment to clean up 24 hours a day, and they will clean up whenever enteromorpha enteromorpha comes ashore.

Judging from the situation in previous years, coastal tourism will be affected by the large-scale invasion of Enteromorpha Enteromorpha. If there is a large area of ??Enteromorpha, visitors should try to avoid going into the water. Enteromorpha Enteromorpha is harmful to the body to some extent. In response to questions from all walks of life about whether the subsidence of Enteromorpha will cause water pollution and cause secondary disasters, relevant Chinese marine experts said that there is no evidence to prove that the settlement of Enteromorpha will cause pollution and will not cause secondary disasters in Qingdao's coastal waters. .

In July 2012, in Qingdao, Shandong Province, enteromorpha enteromorpha struck again. There are patches of Enteromorpha prolifera on both sides of the trestle, just like a meadow. On the 10th, Qingdao Municipal Public Utilities Bureau launched an emergency plan for the disposal of Enteromorpha and immediately moved into the temporary storage site of Enteromorpha.

Up to now, 161 trucks of Enteromorpha have been received, totaling 5,151 tons. Qingdao has experienced large-scale Enteromorpha enteromorpha landings for six consecutive years. Qingdao is also constantly improving its early warning mechanism and treatment methods, but unfortunately, the interception and management of the source of Enteromorpha is still an intractable "deadlock". Enteromorpha invaded wildly, and Qingdao for the first time built a human wall and pulled a net to clear out the invasion.

June 2013

According to the comprehensive analysis results of monitoring data from the North Sea Forecast Center of the State Oceanic Administration on June 14, the area covered by Enteromorpha Enteromorpha in the waters under Qingdao's jurisdiction north of 35°27° north latitude 38 square kilometers, with a distribution area of ??6,727 square kilometers, reaching the disaster level IV early warning (blue) standard in the "Qingdao Marine Macroalgae Disaster Emergency Response Plan". Accordingly, Qingdao City has officially launched the Level IV emergency response procedure for the Enteromorpha Enteromorpha disaster on June 15.

July 2013

On July 3, 2013, Qingdao City, Shandong Province, affected by ocean currents and wind directions, the largest wave of Enteromorpha began on July 2. The sea drifts towards Qingdao. Early on the morning of the 3rd, Qingdao's coast was generally covered by a large area of ??Enteromorpha, and its severity was comparable to the first Enteromorpha disaster in 2008. It is understood that from the research, Enteromorpha was first formed off the coast of Jiangsu. As time goes by, it enters its peak period from June to August every year. At this time, it just floats to the Shandong Peninsula, and the terrain of the Shandong Peninsula just intercepts Enteromorpha. , causing disaster.

The district emergency headquarters launched an emergency plan and mobilized forces to prepare for war. The two marine Enteromorpha unloading points located at the central fishing port of Shazikou and the Wharf of Maidao Island have been put into use. Nearly a hundred fishing boats take turns to salvage and block the Enteromorpha every day.

On July 4, 2013, Qingdao Lao Yinjia Sea Cucumber Factory developed a method of using the summer enteromorpha in the breeding ponds to make winter sea cucumbers and abalone as winter food, which not only solved the problem of enteromorpha invading the breeding ponds It also solves the problem of feed for marine treasures in winter. The nutritional content of Enteromorpha Enteromorpha

Enteromorpha Enteromorpha is rich in carbohydrates, protein, crude fiber, amino acids, fatty acids, vitamins and various minerals. The iron content is recorded in the Chinese Food Nutrition Facts Table as one of the highest in Chinese foods. most. It also contains fat and vitamins. Enteromorpha enteromorpha protein has a complete range of amino acids and a high content of essential amino acids. Among them, the limiting amino acid of Enteromorpha marginalis is lysine, with an amino acid score of 79; the limiting amino acid of Enteromorpha stripes is methionine, with an amino acid score of 80. In the fatty acid composition of Enteromorpha prolifera, the contents of polyunsaturated fatty acids, monounsaturated fatty acids and saturated fatty acids are 50.5, 12.7 and 36.8 respectively, including nearly 4 fatty acids with odd carbon atoms. Therefore, Enteromorpha Enteromorpha is a natural and ideal nutritional food raw material with high protein, high dietary fiber, low fat, low energy, and rich in minerals and vitamins. Enteromorpha prolifera is edible. Fresh moss strips can be eaten after being dried. After being chopped and ground into fine pieces, it can be sprinkled on cakes and pastries to create a special aroma.

Enteromorpha is an alga that people along the coast often pick for food or use as feed. It can be eaten fresh, dried, stored or cooked. There are also people who mix moss strips into flour to make moss strip cakes, which not only adds color but also has a unique fragrance.

Known as "green seaweed" (あおのり) in Japan, it is a very popular seaweed food.

However, it is better to consume artificially cultivated Enteromorpha. Wild Enteromorpha has a very poor taste because it is mixed with other aquatic plants and sediment. Enteromorpha is used as condiments and food in southern Fujian. In Jiangsu and Zhejiang, Enteromorpha enteromorpha is called "moss strip" and it is a common food on the market.

Food moss; or processed into animal feed. However, this treatment method cannot consume a large amount of Enteromorpha and cannot achieve the purpose of controlling pollution. The price of bio-oil as a low-grade fuel on the market is about 1,500 yuan/ton, and the market value of this bio-oil after deep processing can reach thousands or even tens of thousands of yuan per ton. Even if we put aside the income from treating Enteromorpha pollution, once large-scale production is achieved and costs are reduced, the technology to turn Enteromorpha into bio-oil will be equally profitable.

Enteromorpha powder; Enteromorpha is rich in nutrients, including essential amino acids, fatty acids, vitamins and various minerals. Among them, the iron content is the highest in Chinese food. Making Enteromorpha into powder and using it as a food supplement can not only enrich the color of the food, but also improve the nutritional value of the food. Currently, Enteromorpha powder has been used in the production of flour and noodles. There are also manufacturers that use Enteromorpha powder as an important auxiliary ingredient in soup packets.

In the production process of Enteromorpha powder, drying and milling often have a negative impact on the color and nutrition of the product. The color-protecting agent formula used by the author effectively prevents the loss of chlorophyll while desalting. 35's low-temperature drying technology can not only prevent the loss of chlorophyll, but also effectively reduce the loss of nutrients.

The development of enteromorpha enteromorpha tablet food; the fishy smell of enteromorpha enteromorpha itself has caused resistance to the promotion of the original food of enteromorpha enteromorpha. Xu Dalun and others have developed soft-packaged enteromorpha soup snack food. On the basis of ensuring that the nutrients of Enteromorpha are not seriously lost, the Enteromorpha tablets are made into sheets and modulated into various flavors, positioning the Enteromorpha tablets as snacks and ready-to-eat foods. The sensory evaluation results show that corn-flavored Enteromorpha tablets are more acceptable to people.

Exploring effective ways to comprehensively utilize the material resources produced by marine green tides is of great significance for systematically solving the environmental, ecological and economic problems caused by marine green tides. gt; gt; gt; More exciting on the next page?
