To talk about this problem, we must first understand this point? Blue tears? What is this? Speaking of. Blue tears? Believe the answers and real answers that most netizens think of? Far apart? Yes, it may be considered as colored diamonds, jewels or blue liquid. But none of this, but? Blue tears? There is indeed blue in the middle.

Blue tears? It's actually a microorganism that emits blue light. The light emitted by this microorganism is beautiful? Blue tears? With the high tide waves, a string of blue cold light hits, which is romantic and novel under the starry sky! It has also become one of the most beautiful scenery on the earth where we live. However, if this microorganism breaks out in a large area, it will form a red tide and endanger the fishery.

Speaking of red tide, I believe many friends know it. Mozi gives a brief introduction here and will talk about it in detail later. If a large number of red tides occur, it will lead to a large number of fish deaths. Here, let's talk about a cause of death. A large number of red tide organisms will gather in the gills of fish, which will lead to hypoxia and suffocation of fish and eventually die.

Next, shall we meet? Blue tears? What is the scientific name? Greek curved-throated firefly? . ? Blue tears? This is an ostracod, firefly for short, a 3 mm microorganism. It is a plankton living in the bay and a fluorescent animal. Mainly distributed in Japan, Malaysia, China, Taiwan Province Province, Fujian coastal areas, Qinhuangdao, Zhejiang and other regions.

There is a structure called light-emitting gland in this microorganism, which will produce light blue light when stimulated by waves. For example, when we stand by the sea with this firefly at night and beat the sea water, it will make them emit blue light, which is vividly called in Malaysian and China Taiwan Province Province? Blue tears? .

This firefly usually lives near the beach. It lies in the daytime and comes out at night. It lives in the sand layer at the bottom of shallow water. Be stimulated at night, will you? Afraid? , causing fear to secrete luminescent substances. At night, the light emitted by fireflies is a great spectacle at sea.

But this kind of microorganism must survive in seawater, because they need energy from seawater to survive. If you leave the sea for less than 100 seconds, you will die. With the disappearance of energy and light, life will eventually end.

How does this microorganism glow? Because it contains fluorescein, ostracods will secrete yellow fluorescein and colorless luciferase after being disturbed by waves or other factors. The reaction between fluorescein and luciferase will transform chemical energy into light energy through chemical reaction, resulting in light blue light.

However, personal energy is relatively small and belongs to cold light. So it's called? Blue tears? . Have they all appeared in Pingtan East Peninsula in Fujian and Xiangshan in Zhejiang? Blue tears? Phenomenon. ? Blue tears? The occurrence period is unstable, usually from April to July, and the average occurrence will generally disappear within 2-5 days.

Blue tears? It is a noctilucent algae, and its fluorescent band will appear on the beach or on the sea. It is said that noctiluca scintillans is a worldwide red tide organism. If there are too many noctilucent algae, it may mean that there will be red tides there.

According to experts, actually? Blue tears? With what? Red tide? They are all natural phenomena that pollute the ocean and threaten the fish ecology.

Is it a lot? Blue tears? Its appearance will pose a great threat to fish and endanger fisheries. ? Blue tears? What is behind the beautiful scenery? Hidden trouble? .

Blue tears? It may lead to red tide, which is very harmful to fish. According to historical records, red tide is a historical name and a disastrous water color anomaly. Not all red, but also green, yellow, brown, blue and so on. , is a general term for many red tides.

According to records, red tide was discovered in China more than 2000 years ago, and it is also recorded in some historical books or ancient books. For example, Pu Songling in Qing Dynasty vividly recorded the luminous phenomenon related to red tide in Strange Tales from a Lonely Studio.

Red tide will destroy the normal ecological structure and production process of the ocean, thus threatening the survival of marine life. Destroy the bait base of fishing ground, leading to the reduction of fishery production. Fishermen who do mariculture will suffer losses because of red tides. However, the self-pollution caused by mariculture is also one of the factors that induce red tide.

Scientists believe that red tide is caused by organic pollution of coastal seawater. Under normal circumstances, the content of nutrients in the ocean is low, which limits the growth of phytoplankton. However, when domestic sewage, industrial wastewater (mainly food, paper-making and printing and dyeing industries) and agricultural wastewater containing a lot of nutrients flow into the ocean, nutrients will be enriched in the water body, resulting in eutrophication of the sea area.

At this time, the contents of nutrients such as nitrogen and phosphorus, trace elements such as iron and manganese, and organic matter in the water body are greatly increased, which will promote the reproduction of red tide organisms. When other physical and chemical factors in the sea area are conducive to the growth and reproduction of organisms, red tide organisms will multiply rapidly and form red tide.

A large number of red tide organisms gather in the gills of fish, causing fish to die of hypoxia and suffocation. After the death of red tide organisms, algae will consume oxygen in the water during the decomposition process, leading to the death of marine organisms such as fish due to hypoxia. The occurrence of red tide will also increase the viscosity of seawater, lead to the death and attenuation of plankton in non-red tide algae, and finally cause serious damage to the normal ecosystem of the ocean.

That's not true. If the fish swallow a lot of toxic algae, it will lead to the death of the fish, but? Blue eyes? This is non-toxic algae. However, toxic algae will secrete toxins, which will seriously threaten our health and life safety if they finally reach our human mouth through the food chain.

Blue tears? It may cause a red tide, which is a signal of marine pollution. The effective measures to prevent red tide are to prevent nutrient pollution, especially to control a large number of nutrient elements such as nitrogen and phosphorus from entering the water body. Could it be this? Misfortune depends on happiness, and happiness depends on misfortune? All right! ? Blue tears? The scenery is amazing, but there is probably a crisis behind it!

Is everyone okay? Blue tears? What do you think of this beautiful scenery? Do you like it? Leave a message below to discuss.
