My Deep-sea Fishery

Xiang Yang feels that the most fundamental way to deal with the thorn ball is to protect and vigorously cultivate the thorn ball's only natural enemy, the Dafa snail.

Because other methods, such as improving the natural conditions of fish life, or reducing the input of nutrients in the sea, or even artificially changing the temperature of sea water, have no effect on the spiny ball.

If only changing the environment of the seawater can eliminate the thornball, then the thornball will not be considered a natural disaster. This kind of thing is so urgent that it can even leave the seawater to survive on land.

Xiang Yang grabbed the thorny ball and put it in front of his eyes for a closer look.

Its thorns are very long and densely packed, and each thorn is more than one centimeter long. At the bottom of the thorns, there is a very smooth fleshy wall. If you don’t consider its harm to other marine organisms, let alone, Its appearance is still very good-looking, and it can be raised in a sea tank as an ornamental fish.

Of course, Xiang Yang only dared to think about this idea. If he really dared to take this thorn ball back to raise, he would definitely be in trouble.

In January 2012, researchers found nearly a thousand spiny balls on a sandy beach about 300 meters long on Ishigaki Island. Almost all of these spiny balls crawled from the sea to the beach for food because of their unbearable hunger.

In fact, earlier, local fishermen on Ishigaki Island discovered that the nearby spiny balls were growing explosively.

In just a few years, those spiny balls gnawed away all the marine life in the waters around Ishigaki Island, and then began to slowly move towards the beach.

Since the main food of the thorn balls is coral, scientists later speculated that it may be because of the explosive growth of the number of thorn balls that the nearby coral polyps were eaten up, so the remaining thorn balls had to move towards the beach.

But scientists have not understood the reason for the explosive growth of spiny ball football until now.

Xiang Yang looked around again.

Under Xiang Yang's deliberate search, as expected, Xiang Yang soon found several thorn balls.

These spiny balls are gray-black and green, as if covered with moss.

Not far away, Xiang Yang saw a pure white ball of thorns with a diameter of more than fifty centimeters, like a huge spider web.

After seeing the huge thorn ball, Xiang Yang breathed a sigh of relief.

The number of thorn balls at the bottom of this sea seems to be very large. In fact, there are many thorn balls of various types, and the number is relatively rare. This shows that the thorn balls are only multiplying naturally, not growing explosively.

This can also be seen from the side on the surrounding corals that are still growing.

Corals in Antarctica are relatively rare, but also not impossible.

Although most of the coral reefs are distributed in tropical seas, coral polyps are actually only suitable for living in sea areas with a water temperature below 28 degrees Celsius, and some can only survive below 4 degrees Celsius. Excessively high temperatures will cause a large number of corals to bleach and die.

So today's global warming has led to rising water temperatures, which will also accelerate the demise of coral reefs.

Of course, most corals still like to grow in warm waters with a water temperature of around 20°C. 23-27°C is the best water temperature for the growth and development of reef-building corals, so corals are relatively rare in Antarctica.

These corals that grow in the extremely cold waters also have different appearances, and more colors, and the clusters are very beautiful. Seeing them, Xiang Yang seems to have arrived at the Dragon Palace on the bottom of the sea.

Xiang Yang was worried that crew members who did not know Thornball would be in danger at the bottom of the sea. He didn't dare to stay on the bottom of the sea for a long time, and he didn't even bother to appreciate the beautiful corals. He stuffed the coral group into the net bag, and then Xiang Yang quickly moved towards the seabed. The boat swam past.

"Captain, why did you come up so soon?" Some crew members were a little surprised when they saw that Xiang Yang had come up only a few minutes after going into the sea.

"I found this under the bottom of the sea. As soon as someone emerges from the bottom of the sea, call them over. I have something to say to them." Xiang Yang took off the net bag at his waist and took out the thorn ball.

When the crew heard this, they were immediately excited. It must be a treasure that Xiang Yang can attach so much importance to.

A crew member asked: "Captain, what is this? Is it worth money?"

As he said that, the crew member stretched out his hand, wanting to touch the thorny ball.

"Snapped."

Xu Fang on the side directly patted the crewman's hand back, and then scolded: "Can't you see so many thorns? How dare you reach out and touch it, are you looking for death?"

"I brought leather gloves." The crew member immediately aggrieved.

Xiang Yang shook his head, "This thing is called a thorn ball, and the thorns on it are very sharp. The main function of the leather glove on your hand is to keep out the cold, and it cannot resist the poisonous thorns on this thorn ball."

"This thing is called a thorn ball? Is it worth it?" the crew member asked.

"It's worthless, and it's a terrible thing. I've seen this thing in the East China Sea, but I didn't expect it to be found in the Antarctic." Xu Fang frowned, "Captain, are there many such thorn balls under the sea?"

Xiang Yang nodded, "Yes, I found several of them, otherwise, I wouldn't have swam back to the boat to draw everyone's attention."

When Xu Fang heard this, his face immediately became serious.

Others don't understand the threat of the Thorny Ball, so how could he, Xu Fang, not understand?

Every year, a large number of diving enthusiasts die on this thorny ball.

The thorny ball contains a large amount of neurotoxins. Once stabbed by the thorny thorns of the thorny ball, the person will immediately lose consciousness, and then suffocate to death in the bottom of the water.

"Captain, can the thorns of this thorn ball pierce our diving suit?" Xu Fang asked with a rather ugly expression.

In Xu Fang's view, if the thorns of the thorn ball could not pierce the diving suit, then Xiang Yang would definitely not come up.

However, now Xiang Yang is holding a thorny ball with his hand. Judging from this, the thorny ball should not be able to break through the diving suits Xiang Yang bought.

"I tried it. Wearing my diving suit, if I don't kill myself, there will be no danger under normal circumstances, but I'm afraid that some crew members don't know this thorn ball, and they still hold it as a baby. Hitting up, the small ones won't pierce, which doesn't mean the big ones won't pierce either, I just saw a thorn ball with a diameter of about 50 centimeters under the seabed." Xiang Yang said.

Hearing this, Xu Fang breathed a sigh of relief.

As long as it cannot be pierced under normal circumstances, the crew members underwater will not be in too much danger.

But after hearing what Xiang Yang had said, Xu Fang suddenly became nervous again. A prickly ball with a diameter of 50 centimeters would not even dare to provoke a prickly turtle, would it?

Although the diving suit on their boat is said to be indestructible even by sharks, can it possibly withstand the poisonous needle of the thorn ball?
