My deep sea fishery

Fang Friends gathered, and suddenly.

Chen Qingsheng also surprised his eyes, "50 meters? The captain, are you joking?"

Xiangyang shake his head, and truthfully said: "I am not joking, the tentacles of jellyfish can be longer to 50 meters."

In many people's impression, jellyfish is a simple, cute, but simple marine life with toxins.

But the familiar Xiangyang knows that the terrible level of jellyfish is far more than that.

Especially in recent years, the more precautions that appear in the eastern sea area.

The more the more the jellyfish is more tired than other jellyfish.

Moreover, the more the jellyfish is terrible.

The maximum, the more the parents can be as long as the umbrella diameter, and weigh two hundred kilograms.

A adult, the more the jellyfish can eat all the floating creatures in a large swimming pool within a day, and as long as it is the place where the jellyfish appears, there is no fish survival.

Thinking of this, Xiangyang shakes his head, quite emots: "In the big ocean, fish has been survive in the top of the food chain, even if there is dinosaur with straight shell, there is also fish to dominate, hundreds of millions In the past, fish never lost to any other marine life. I didn't expect that it is actually lost to the jellyfish due to the appearance of the jellyfish. "

"This is also something wrong, the more the jellyfish is really terrible." Xia Pengjie said.

In fact, the more the more the jellyfish is also there.

The more the jellyfish is known as Shahai Yu, and there is also frequent in my country's sea area.

Because the more the more the destructiveness of the jellyfish on my country's fishery resources is too big, my country has long, the Academy of Sciences, the more precautions, the jellyfish, the mainly study, and the main research.

After research, scientists found that the more the water of the jellyfish, in addition to the same amazing predation ability, there are also very amazing reproductive capabilities.

Different jellyfi, there are different reproductive methods, and the more the jellyfish can also reproduce in the foot capsule.

When the jellyfish's water sinks into the sea, they can move on the shelf, while they can leave some organizations, the researchers are called a sugar, and these bag caps can breed more water.

This kind of self-replication, asexual breeding, is enough to make the initial 100,000 fertilized eggs, and finally evolved into billions of water.

When the water is further grown, a stack of small jellyfish will split by one, and the final quantity will reach billions.

The more the prior front jellyfish has such a propagation method, and it is definitely an important reason for the explosing of joy in these years.

However, Xiangyang feels that this is definitely not the main reason for the big outbreak of the jellyfish.

Because the more the more the jellyfish is a newly discovered jellyfish, it is not a new type of water, and it has been expensive in the ocean.

If it is necessary to reproduce the breeding, it can cause the jellyfish to break out, then this ocean is given by the jellyfish as early as 100 million years ago.

Of course, not all the jellyfish is like the more predecessors.

Some jellyrs are very small and amazing.

Xiangyang has seen a jellyfish called lighthouse.

Compared with the huge body of the jellyfish, the head of the lighthouse is very small, and there is only 5 mm in diameter.

Lighthouse jellyfish is very magical, is a true longevity, they can return to the old bodies, become a young body, and then grow, it is very incredible.

Many scientists in the world are studying the life of the lighthouse, why can you have a long life, and a life is concerned.

Of course, compared to the rumor of the lighthouse is not old, first solve the harm of the jellyfish to humans, this is the first thing to do.

After analyzing, scientists found that the jellyfish's water bodies not only had a characteristic of large numbers, that is, sleep.

When the external conditions are not suitable, the water can be hibernated in the seabed for decades, waiting for the opportunity to mature and start the activity.

According to this feature of the water, Xiangyang believes that the main cause of the ambient burst in recent years, or the environmental changes.

There is a tendency to rise year by year, and there are some subtle changes that have been continued for many years.

From 1980 to now, the average eutrophication of my country's offshore seawater has increased three times, and Xiangyang feels that this is one of the main causes of jellyfurt.

In the past sixty years, human beings have obtained hundreds of tons of fish from the ocean, which are wild animals, not human farming.

At the same time, human beings put more than 10 billion tons of garbage to the ocean, resulting in a large change in the entire ocean.

Human society has rapidly developed, producing a large number of industrial and domestic garbage, and there is more nutrients that have fallen over the ocean.

In this way, algae plants are flooding, red tide, and squats.

As a result, algae plants provide sufficient food for floating creatures, and the floating organisms are multi-breeding, and the floating creatures are a jellyfish, they begin to cross overbearing.

In the past, the marine food chain has always been a pyramid structure, from the bottom of the bottom of diatom, single cell plants to the top of large fish and marine mammals, this structure has stabilized hundreds of millions of years.

But the outbreak of the jellyfish breed, so that they have a big floating creature, so that the fish lacks the source of food, the ocean food chain is broken.

Xiangyang said: "No matter how the jellyfish is warming or excessive fishing, it is caused by eutrophication of the ocean rich, I feel that human beings are responsible for the future, so these , I have encountered, So, in any case, you have to catch some. "

"I support the doctor's approach." Chen Qingsheng's first statement.

"I also support it." Fang Friendou shouted loudly.

Xiangyang smiled slightly, "In this case, then start fishing, remember, must pay attention to itself, in the process of salvage, you must wear protective clothing from start."

Said, Xiangyang himself took a helmet and took a fish and went to the neighborhood.

These is actually very fishing.

Their body is very soft, just like plastic bags, at least 90% of the whole body is water.

Near, use a long rod with a hook to fish, as long as the jellyfish is hooked by the hook, then hold the pole directly, pull it up to the deck is, it is definitely not possible to run away.

The amount of jellyfish in this watery is very much, and only the body is more fat, it is the best in the jellyfish.

Soon, Xiangyang waves the fish, and has a dozens of jellyfish from the sea.

Because this is there, there is no technical content, it is the reason for physical activity. Chen Qingsheng is more than even more than Xiangyang, soon, there are several water tanks filled with jellyfish.
