And the most important thing is that red tide is divided into four stages. The process of red tide can be roughly divided into four stages: starting, developing, maintaining and extinction.

Initiation stage: There are a certain number of red tide species in the sea area, and the various physical and chemical conditions of the water environment at this time are basically suitable for the growth and reproduction of a certain red tide species.

Development stage: also known as the formation stage of red tide. When a certain population of red tide organisms in the sea area has a certain number of individuals, and the external environment such as temperature, salinity, light, nutrition, etc. reaches the optimal range for the growth and proliferation of the red tide organisms, red tide organisms can enter the exponential proliferation period and may develop into red tides faster.

Maintenance stage: The length of this stage mainly depends on the physical stability of the water body and the richness of various nutrients, as well as the rate and amount of supplementation when the nutrients are consumed in large quantities.

If the sea area is calm at this stage, the water body is mixed with the horizontal mixture poorly, the water mass is relatively stable, and nutrients, etc. can be supplemented in time, the red tide may last for a long time.

On the contrary, if there is a typhoon, rainy rain, poor stability of the water, or is consumed due to nutrients and is not replenished in time, the red tide phenomenon may disappear quickly.

Epiration stage: The so-called expiration stage refers to the process of the disappearance of the red tide phenomenon.

The causes of disappearance may be wind, rain or exhaustion of nutrients. It may also be because the temperature has exceeded the appropriate range of the red tide organism. It may also be due to the increased tide, the red tide is spread, etc. The disappearance of the red tide is often the most serious stage of the harm of red tide to the fishery.

After hearing this, the audience in the live broadcast room could not have thought that a Chi Tide had so much knowledge. They were very curious. The island owner's head didn't seem to be very big, but why did he know so many things?

They even split the island owner's head to see if the structure inside is different, which is why the difference between people is so big.

But this must be just thinking about it!

Soon the audience in the live broadcast room saw dead fish and shrimps floating up on the red sea water, and they were still in a continuous manner.

As time goes by, more and more marine creatures are constantly dying. If this continues, it will probably not take long for the entire marine creature to die!

"Is there any way to prevent this island owner? Otherwise, if this continues, all the creatures in this large area of ​​sea will die! It makes people feel a little unbearable to see it."

"I don't know if there will be people without conscience who salvage these dead marine creatures directly and buy them as ice cream. I just heard the island owner say that this red tide is also poisonous. If others eat it, it will probably be a big trouble."

"Oh, it's true that the pollution is too great, otherwise such a thing wouldn't have happened. If such a red tide continues to occur in the sea, it will probably not take long for all the marine creatures to die!"

.........

Xiao Hai saw these barrage and said, "You are indeed not wrong. The ocean is a complex ecosystem where creatures and environments are interdependent and restrictive.

The material circulation and energy flow in the system are in a relatively stable and dynamic balanced manner. When a red tide occurs, this balance is disturbed and destroyed. In the early stages of plant red tides, due to the photosynthesis of plants, the water body will have high chlorophyll a, high dissolved oxygen, and high chemical oxygen consumption.

This change in environmental factors has caused some marine organisms to fail to grow, develop, and reproduce normally, causing some organisms to escape or even die, and destroy the original ecological balance."

Moreover, international countries are also paying great attention to this red tide. They have also carried out research on the formation mechanism, prediction and prevention and control application technologies of red tide, which is a good way to treat both the symptoms and the root causes.

The impact of red tides on biological resources has become one of the global issues that the relevant United Nations organizations are concerned about. Several international seminars on red tide issues have been held and long-term research plans have been formulated, focusing on the mechanism of red tide generation, monitoring and forecasting of red tides, and methods for controlling red tides.

However, for how to manage it, but from the current technology perspective, there is nothing effective to suppress the large-scale red tide, but for small-scale red tides, there is still a certain ability to manage it.

Although many experiments have been conducted, the effect is not ideal. The main purpose is to use chemical drugs to kill red tide organisms, but the effect is poor, the cost is expensive, and the economic and environmental benefits are not good. Some use net tools to catch red tide organisms, or use isolation to protect the breeding area; some are experimenting with insect control methods, breeding ridges and two shells to prey on red tide organisms, etc.

These methods have not made great breakthroughs in the experiments. From the perspective of development trends, biological control methods, that is, isolate appropriate control organisms for red tide algae to regulate the eutrophication environment in seawater, will be a better choice.

The Chinese country's red wave is also very serious. Since 2002, it has developed from fifty or sixty times a year, and now it has three or four hundred times a year. The number of occurrences has increased a lot.

If an effective solution cannot be found, the situation will probably continue to worsen. However, so many countries around the world have been studying for so many years, but there is not even a solution.

Xiao Hai also said at this time: "It can be seen that the global research on the ocean is not deep enough, so in order to protect our beautiful earth, everyone must protect the environment and not just say it."

"Otherwise, our descendants may never see such a vast and beautiful sea again, or even such a beautiful environment," he added.

After hearing this, the audience in the live broadcast room wondered whether they were usually considered an environment-protecting person and whether they had littered everywhere.

Soon everyone has an answer in their hearts! If everyone could be so conscious, the current environmental problems would not be so serious!

It has been nearly an hour since the formation of the red tide! Now the marine creatures in this sea should have almost died!

Because the dense corpses can be seen everywhere on the sea. If someone with dense phobia is intensive, he will probably not even sleep well tonight!

There are countless marine creatures on the sea surface now. They have lost their lives in just one hour. Maybe they don’t even know why they die!
