Silver carp, bighead carp, grass carp, herring, catfish, loach......

Freshwater shrimp, crabs, hydroacoustic insects and even waterfowl......

Looking at these dead creatures floating on the water, Ao Muyang's face turned pale!

Yang Shuyong said cautiously: "This is poisoned, but who would do this? ”

There is another thing he didn't say, that is, people who do this are tired and crooked, this is blatantly pouring feces on Ao Cunba's face, the last person who did this raised chrysanthemums in prison, who was so bold?

Poisoning fish is not uncommon in rural fish farms, especially those contracted private fish ponds, which are occasionally sprinkled with pesticides by red-eyed or vengeful people.

Therefore, in the countryside, if someone has contracted a fish pond, the whole family will go to live next to the fish pond, and the people in the city think that they are afraid that someone will come to steal fish, but in fact this is not the case, they are afraid that someone will come to poison them.

The loss of stealing fishing is only a few fish, and when the owner finds out, it is at most a shout, and poisoning the fish pond is a dead nest, which can make people bankrupt.

Ambergris Lake has not been poisoned in history, perhaps because no one has contracted this lake before, and second, because the lake is vast and has a strong carrying capacity for pesticides, and no one has done such a thankless job.

Now, that's happening.

Ao Muyang reported to the police station as soon as possible, and Song Gongming drove over to take pictures to check the situation, and then asked: "How can you judge that the fish here were poisoned, not electrocuted?"

"It's poisoned, if this thing was electrocuted by the electric fish thief, then why don't they take it away? In addition, you see the death of these fish, and the dead water birds, they are definitely poisoned. ”

Song Gongming nodded yes, Ao Muyang asked him what to do, he said: "To poison so many fish, a lot of pesticides must be used, I will immediately check the pesticide station and store in our town when I go back, now the pesticide sales in the town must be registered, and whoever does it will definitely not be able to run." ”

"What if it's not the pesticides we bought in our town?" Ao Muyang asked again.

Song Gongming said: "Then go to the surrounding towns and even counties to investigate, and the people who poison the lake can't be outsiders, usually locals, and they want to buy pesticides locally." Even if you buy it from other places, you can find some clues, so don't get angry yet. ”

Ao Mukang, who heard the news, whispered to Ao Muyang: "Could it be an accomplice of the foreign electric fish thief?"

Ao Muyang also thinks so, the biggest suspect in committing the crime is the electric fish thief in the field, and the electric fish and poisonous fish are not separated, and the electric fish thief often does such a thing as poisoning the fish.

For them, anyway, the electric fish is already a matter of giving birth to a son, so it is nothing to have another poisonous fish, at most there is no little Jiji for the son.

After the police came to collect evidence, he asked the villagers to salvage these fish, ambergris lake belongs to the scenic area, there are tourists visiting the lake every day, if you see the lake full of dead fish, who is in the mood to go to the lake to play?

This incident alarmed many people, and Professor Yin, who has a habit of getting up early and walking, also came.

The old man walked around the lake for a while and then went to find Ao Muyang and said, "I heard from the people in the village that the police station has been here?"

"Yes. ”

"Are they going to look into this case from the pesticide approach?"

"Yes. ”

"You call them, this road does not work, the fish and shrimp in the lake are not poisoned by pesticides, but by the hands of poisonous fish vines. Professor Yin solemnly held up a tender green branch to show him.

Ao Muyang subconsciously asked, "Poisonous fish vine?"

Speaking of poisonous fish vines, he is no stranger to them, and the fishermen know that this thing is the nemesis of fish and shrimp.

However, there is no such plant growing in the Red Ocean, and the fishery is one of the pillar industries of the Red Ocean, and the local management of this plant is strict, and once someone is found to be planting or carrying, it will be immediately investigated and dealt with according to the law.

Professor Yin nodded, handed him the branch and said, "I looked around the lake, there are quite a few of these things on the ground, someone must have brought a large number of poisonous fish vines here." Tell the villagers that the root system of the poisonous vine is highly poisonous, and it will always discharge rotenone into the water, which will always harm the creatures in the lake. ”

Ao Muyang hurriedly gave an order, and the fishing boat replaced the dragnet with a trawl net to carry out investigations in several areas with a large number of dead fish.

He personally led people to collect poisonous fish vines along the lake, and Professor Yin came to help, and at the same time introduced him to the poisonous fish vine plant.

Poison fish vine is a leguminous vine, climbing shrub, all bald, leaves, rhizomes and fruits are poisonous, among which the roots of the plant are particularly toxic, because the root system contains a lot of rotenone.

Rotenone is highly toxic and very harmful to fish, but it is also an excellent insecticide, which can control more than 800 kinds of pests, and many pesticides contain rotenone and its species.

Professor Yin asked Ao Muyang to clean up the poisonous fish vine plants that fell on the edge of the lake first, in order to prevent them from being eaten by humans and beasts. The whole plant of the fish vine is poisonous, and the harm to humans and animals is not as terrible as that of fish and insects, but if it is eaten by mistake, there will also be a series of problems, such as abdominal pain, vomiting, paroxysmal spasms, slowed breathing, etc., if the rescue is not timely, it will also die due to paralysis of the respiratory center.

There are many kinds of fish vines, and Professor Yin told Ao Muyang that this is the hairy fish vine by their lake, which is the most toxic, and the content of rotenone in its root system is as high as 12%.

"If you find a pond in the Jiangnan water town, as long as you smash the roots of the hairy fish vine and put it into the pond to stir it up, then within a few seconds there will be fish floating heads, and within a minute, the surrounding fish will start to die in large numbers. Professor Yin said solemnly.

As soon as he heard that this thing was so terrifying, Ao Muyang frowned and said, "Professor, the poisonous fish vine is so harmful to the fishing industry, the state doesn't care about it?"

The old man shook his head: "I can't care, this is a wild shrub, there are many bushes along the riverbank, bushes on the seaside or mangroves near the coast, and there are many on the slopes and in the wild in some places, because it can reproduce by cuttings, and it can germinate in all seasons, and it is easier to survive in the rainy season." ”

"Moreover, this fish vine will not grow into the fish pond of the fish farm on its own, it is an insecticide extract for the scientific research department, it is a Chinese medicinal material, dried fish vine can treat eczema, rheumatic joint swelling and pain, and many villages in southeast China have planted this thing. ”

When Ao Muyang heard this, he understood that the Fisheries Bureau had already found out the source of these electric fish thieves, and their hometown was southeast China.

He believed that it was revenge from the electric fish thieves, who roamed the coastal areas and changed the sea area after harming one area, and there were many people.

There are at least hundreds of electric fish thieves who have come to the Red Ocean, and now they have not caught half of them, and there are still large groups of fish that have slipped through the net, and those people must have found out that their companions were caught by the people of Longtou Village, so they attacked Ambergris Lake to retaliate.
