Chapter 693:My Deep-sea Fishery


If the place where combustible ice is found is not in the Antarctic, Xiang Yang will definitely report the discovery to the country.

But even if it is in Antarctica, Antarctica is rich in various resources, but they are not yet able to be exploited.

Xiang Yang threw away the combustible ice and continued to search for traces of Antarctic deep-sea crayfish on the bottom of the sea.

In fact, Xiang Yang was extremely curious about this sea area in his heart.

Because the seawater around the Antarctic continent is rich in nutrients, coupled with the clean seawater, the number of life in the seawater is generally extremely high, but the number of life under this sea area is extremely scarce.

There must be a reason for this.

Xiang Yang is looking for Antarctic deep-sea crayfish while also looking for the reason for the scarcity of living things in this sea area.

"Is it because of combustible ice?" Xiang Yang couldn't help but think of the combustible ice he had discovered before.

However, there are many places with combustible ice on the seafloor, and Xiang Yang has never heard of the impact of combustible ice on marine life.

"Huh? This is?" Xiang Yang, who was walking on the seabed beach, suddenly felt as if he had stepped on a hard object. He quickly raised his foot, squatted down and looked in that direction carefully.

I don't know this, but I was shocked when I saw it.

Xiang Yang's forehead was cold and sweaty, and he was too careless, and stepped on this thing. Fortunately, his diving suit has a thicker protection design on the soles of his feet. Otherwise, his little life may have been explained here today. .

I saw a gray-black semi-spherical creature with bright red spines on the side of Xiang Yang's feet.

The name of this thing is the spiny ball. In a very popular cartoon "The Adventures of Little Carp" in our country, the direct reason why the protagonist Bubble leaves the carp bay to find the real dragon is this spiny ball. It is the nemesis of most aquatic creatures. , The vitality is extremely tenacious, and there are not too many natural enemies in itself.

However, spiny ** are generally distributed in the tropical coral environment of the Red Sea, the Indian Ocean and the Pacific, and it is very rare to find them in the Antarctic.

But it does not mean that spiny ** cannot grow in Antarctica.

Even if the spiny ball lives in tropical waters, it hides under the icy rocks or corals of the sea, and feeds on sea cucumbers that also like the cold environment.

Xiang Yang grabbed the spikes on the surface of the spiny sphere, and he was relieved to see that the spikes did not pierce his gloves.

The spines on the surface of the spiny ball contain very severe neurotoxins. Once they are stabbed by it, they will basically be poisoned to death. If the poisonous spines of this spiny ball can pierce Xiang Yang's protective clothing, the Yang only Able to recall all diving crews immediately to prevent accidents.

But since this spiny ball can't penetrate Xiang Yang's protective equipment, there is nothing to worry about that Yang, and there is time to study this spiny ball.

The spiny ball in front of Xiang Yang's eyes was about 20 centimeters in diameter and had fifteen arms and legs.

The largest spiny ball is said to be able to grow to one meter in diameter. The spiny ball of that size must have sharper spines. Whether the protective clothing can be defensive or not.

But with such a big spike, if the crew were accidentally stabbed, that Xiang Yang could only say that the man was blind.

Finding this spiny ball, Xiang Yang immediately knew why the fishery resources in this sea area were so scarce.

Echinococcus not only dislikes marine animals, but also marine plants and even marine insects.

In the coral reef sea, spiny * gnaw on corals. Under natural conditions, they will pose a serious threat to coral reefs, and will destroy most of the marine life in the entire coral sea except for spiny * themselves.

In waters where there is no coral reef, spiny ** are even more domineering. They wantonly gnaw at the roots of algae and seaweed, and completely destroy all the animals and plants within the reach.

In 1970, the Australian Great Barrier Reef, which was more than 2,000 kilometers long and more than 50 kilometers wide, was damaged by spines.

At that time, about one-fifth of the entire Australian Great Barrier Reef was covered with spines.

Those spiny ** swallowed the coral polyps on the Great Barrier Reef in Australia, leaving behind countless white coral skeletons.

A spiny ball with a diameter of only 20 centimeters can eat two square meters of coral in one day, and the appetite is surprisingly large.

Moreover, the eruption of spines is a natural disaster without any regularity, and it is not caused by human factors.

Scientists have discovered after research that as long as the salinity of the sea water is suitable for the growth of spines, no matter the environment is good or bad, the temperature is high or low, they will reproduce in large numbers.

The spiny ** just born are not spherical.

When spiny ** are small, they are a kind of plankton. At this stage, most fish can destroy them to prevent future troubles.

The growth process of spiny ** is actually extremely difficult. It needs to pass the most fragile initial stage, the easy to die second and third instar stages and fish favorite prey.

However, once the spiny ball has passed the terminal larval stage, the spiny ball is almost invincible in the world. In the entire ocean, except for the big snail which can prey on the spiny ball, almost no creature can prey on the spiny ball.

If there are no natural enemies, the spines are not terrible. The ocean has a very strong ability to self-regulate, and there is always a way to kill the spines.

But the problem is that while there are almost no natural enemies, the spines still have vitality that scientists find incredible.

When food is sufficient, spiny ** can eat several square meters of polyps or other equivalent foods in a day.

When food is scarce, a spiny ball will not starve to death in the first half of the year, and it will still live and live freely.

The most important thing is that the spiny ball has a very strong regenerative ability.

Another name for the spiny ball is also called the spiny sea star, because it has the same ability as the starfish. When it is removed by the NPC, each piece can grow into a complete spiny ball.

With strong reproductive capacity, strong vitality, and with cell-like division functions, such organisms cannot be controlled by nature through self-adjustment.

Even if humans want to inhibit the growth of spiny balls, there are many difficulties.

Someone once thought of a deadly way of injecting formalin into the spines to inhibit the growth of spines.

But this method is tantamount to catching the mosquito and feeding it mosquito medicine.

Some sea areas have indeed been attacked by spiny balls. Humans can use this method of treating the head and feet to control the reproduction of spiny * in a short period of time, but the spiny * do form on a certain sea area. Before the threat, using this method to deal with the spines of the entire ocean is simply nonsense.
