Although Enteromorpha prolifera is non-toxic, a large-scale outbreak is not a good thing. Like red tide, prolific Enteromorpha will block the sunlight and affect the growth of algae on the seabed: dead Enteromorpha will also consume oxygen in seawater; Other studies show that the chemical substances secreted by Enteromorpha prolifera are likely to have adverse effects on other marine life.
The outbreak of Enteromorpha prolifera will also seriously affect the landscape and interfere with tourism and water sports, which is the biggest adverse effect that people want to eliminate. Therefore, large-scale green algae outbreaks such as Enteromorpha prolifera are called "green tides" abroad and are regarded as marine disasters similar to red tides.
It is generally believed that the eutrophication caused by human discharging a large number of pollutants containing nitrogen and phosphorus into the ocean is not only an important cause of many red tides, but also an important cause of many green tides.
Enteromorpha hit the Yellow Sea again;
Recently, Enteromorpha prolifera broke out along the coast of Qingdao, and some netizens described it as "the sea turns into grassland every second".
This is actually a green tide disaster of Enteromorpha in the Yellow Sea. According to public information, Enteromorpha prolifera, as an algae, will absorb a lot of oxygen during its growth, threatening the survival of other marine animals and plants, and will stink after losing water. A large number of Enteromorpha floating on the shore will also block the waterway and affect coastal fisheries and tourism.
According to the news from emergency headquarters of Enteromorpha prolifera, 202 1 Enteromorpha prolifera emergency response has been launched in Qingdao, and four lines of defense have been set up, including pre-salvage line at sea and clearing line at shallow sea shore. Recently, a staff member of Qingdao Ocean Development Bureau told this newspaper that the salvage and clean-up work in this sea area is still going on.
According to Qingdao Science and Technology Bureau, the scale of Enteromorpha prolifera disaster in 20021Yellow Sea has far exceeded previous years, reaching the historical maximum. According to CCTV news, as of July 3, Qingdao has dispatched more than 7,300 ships and salvaged about 240,000 tons of Enteromorpha.
