The wind blows the lake, making it look green.

Unlike natural green, when cyanobacteria appear in large quantities, the water surface is covered by thick algae, and endless small algae gather together, which looks disgusting.

Moreover, when the wind blows the lake surface and creates waves, the cyanobacteria float from south to north, like a layer of green putty powder piled up by the lake, carrying a foul smell, making people feel uncomfortable.

It can be said that natural green is US dollar green, and water green is green on the top of the head, giving people a completely different feeling.

Ao Muyang felt that this thing had nothing to do with Wangjia Village. Water blossoms were a natural disaster. Although it happened violently this time, it should be that the water in Ambergris Lake is rich in nutrients, which led to the outbreak of cyanobacteria as soon as it reproduces excessively.

Ao Mudong didn't think so. He said, "Longtou, I told you that there will definitely be someone who caused trouble. Think about it, you just contracted this lake, but it ended up in such a mess. There hasn't been such a water blossom in ten or twenty years before. If you say that no one is making trouble, then I don't believe it."

"No one has to do something wrong, and no one can do something wrong. There is poisonous fish meal, but there is no algae to enrich the powder." A voice sounded, and Ao Muyang turned around, but Su Penghui came.

Su Penghui looked at the lake with a relaxed expression on his face: "This is the early stage of the outbreak of Shuihua, and it is not serious, but there are many fish, shrimps and crabs in your lake, so you have to deal with it quickly."

Cyanobacteria are the food for fish, shrimps and crabs, but they are also killers. The collar algae in them can quickly produce lethal factors, destroy the gill tissue of fish, interfere with the normal progress of their metabolism, paralyze the nerves, and cause them to die.

In addition, some species of cyanobacteria are not only poisonous, but also decompose the dead individuals to produce biological toxins cyanobacteria toxins, microcystis toxins, etc. When the amount of these toxins is large, they can directly cause poisoning and death of breeding objects, and can also harm breeding objects through the accumulation effect of the food chain, until the human body is endangered.

What Ao Muyang is afraid of is their consumption of oxygen and its barrier to sunlight. If there is not enough sunlight to shine into the lake and enable the vegetation in the lake to photosynthesis and release water-soluble oxygen, then the Yexian crabs, pearl mussels, and various fish in the lake will have problems.

Su Penghui is worthy of being a relevant expert. He quickly formulated a handling plan: "First of all, Xiao Ao, please contact silver carp and bigfish fry quickly and put them into the lake. Silver carp and bigfish are fond of eating cyanobacteria, which kills two birds with one stone. It not only allows them to eliminate cyanobacteria, but also feed big fish."

Ao Mudong scratched his head and said, "Is it too late to cram the Buddha's feet for a while? How many days does it take for the fish fry to eat these things?"

Su Penghui smiled and said, "Yes, so I said 'first,' this is a natural prevention and control method. The green tide phenomenon is mainly prevention and it is repetitive. Raising silver carp and bighead carp is for the sake of future considerations."

Ao Muyang waved his hand to Ao Mudong and said, "Brother Dong, don't interrupt, let Teacher Su say, go and contact fish fry. I remember there is a state-owned fish fry farm in the county, but it has not gone bankrupt, right?"

"No, but Longtou, this big man is together, why don't he interrupt?" Ao Mudong said with a smile.

"When is it time for Mala next door to talk to me?" Ao Muyang was angry for a moment, kicked him in the butt and kicked him into the lake.

Ao Mudong screamed and braked all the way, and almost fell into the lake and got covered in blue algae.

Su Penghui also said: "Secondly, you need to buy Bacillus algae and Bacillus sprinkled with about one pound of water. This thing is a microbial preparation and has not had that much impact on the environment."

Ao Muyang asked, "Do you want to turn on the aerator? I'm afraid that the fish, shrimps and crabs in the lake will die of hypoxia."

Su Penghui smiled and said, "The fish, shrimp and crabs in the lake are considered wild, they are not so delicate."

Ao Muyang explained: "I have seen reports about this thing before, and I always say that it will cause losses in freshwater aquaculture, so I'm more afraid."

Su Pengyu nodded and said, "Yes, they are indeed prone to hypoxia in the water. But that means that in the breeding state, artificial breeding density is high, and the density of fish, shrimp and crabs in wild lakes is reasonable. They will actively surface or live in waters where water blossoms are not polluted so much. In short, this problem is not big."

There are other methods next, such as balancing the nitrogen and phosphorus ratio. He asked Ao Muyang to buy water-soluble inorganic phosphorus to change the nitrogen and phosphorus ratio in Ambergris Lake, and accelerate the cultivation of beneficial algae such as green algae and diatoms to quickly grow into dominant algae species to inhibit the growth of cyanobacteria and thus improve the overproliferation of cyanobacteria.

After proposing a series of measures, he sighed: "Now the global greenhouse effect, no matter how big the weather is, the temperature and water temperature are a little high. If it exceeds 25 degrees, the growth rate of cyanobacteria will be greatly improved compared with other algae. I have to tell the Fisheries Bureau that they will issue a high-temperature warning to prevent other farmers from losing money."

Ao Muyang smiled bitterly and said, "Hurry up, our Ambergris Lake has provided you with a vivid example."

From the end of May to the beginning of June, Longtou Village revolved around Ambergris Lake.

All the boating activities on the lake have stopped. How to do this?

However, the boats were not idle, so Su Penghui arranged for everyone to use the small-eyed fishing net to drag the cyanobacteria on the lake surface, gathering all the cyanobacteria to transport them to the garbage ship.

This is a very effective way to treat symptoms but not root causes. Hundreds of small boats and rafts take plowing and trawling nets. After three or two times, the lake surface becomes clearer again.

On Children's Day on June 1st, even primary school children came to help. Of course, Ao Muyang gave a reward, and each child who helped collect blue-green algae could get a shopping reward of fifty yuan.

Children can go to the small supermarket in Aomucheng to buy things, and they can only be settled within fifty yuan.

For a moment, the lake was in full swing. Ao Muyang felt that the green tide did not cause much disaster, but instead increased the cohesion of the village.

Ao Wenchang also had this view. He wrote a picture of "Duan Xingbang" hanging it on the village committee. Mr. Ao Zhiming thought it was unlucky, so he took it home and made a table mat...

Ambergris cannot receive tourists for the time being, so the tourists in the village spend more time on the sea.

In order to express apologies for tourists who came to the village but experienced the Shuihua incident, and to express gratitude for parents who brought their children to travel on Children's Day, many activities at sea in the three days of early June are not charged or half-price. For example, the boat seat for whales is half-price, the fish used to feed whales is free, and the tickets for Ming Dynasty warships are also free.

Du Tanzhi, who came to the village to check the progress of the resort decoration, read the announcement, and said happily: "Lao Ao, you are such a clever little ghost, you are a good way to engage in tourism business."

Ao Muyang smiled helplessly and said, "Just be willing to bear the losses, what is this good method?"
