My Deep-sea Fishery

"Look at that." Xiang Yang pointed to the sea wolf seal and said.

A group of people looked over there and saw the sea wolf seal staring at a seagull about to move.

It crawled on the ground, approaching a little bit.

As a result, before it could launch an attack, the big seagull found something was wrong and fluttered its wings into the air.

The sea wolf seal immediately rushed forward angrily, but only rushed into the air. It could only roar, and then reluctantly shifted its target and stared at an unlucky seabird that had died.

"Captain, just ignore the sea wolf seal and watch the sea." Chen Qingsheng said at this time.

"The sea?"

Xiang Yang turned his head and looked at the sea.

I saw the silver light on the sea, reflecting light everywhere. Obviously, schools of fish appeared under the water.

But Xiang Yang was not moved, "Looking at the light refraction, it should be krill."

"Well, wait, it looks like a cross jellyfish." When Xiang Yang was on the brick, he suddenly saw an orange in the water, like an umbrella, with countless filamentous creatures floating under the umbrella tray.

The cross jellyfish is soft as silk and looks beautiful and docile, but in fact it is an extremely cold ocean killer.

However, compared with the transparent body of ordinary jellyfish, this jellyfish has a color on its body, which is very conspicuous when swimming in the sea, and will not let fishermen get caught in the seabed fishing without knowing it.

"It seems to be a cross jellyfish." At this time, Gao Chuang said solemnly.

Although the cross jellyfish has a color and cannot approach its prey silently, its predation technology is very superb. They use ancient predation methods and use drifting to forage. Creatures like krill inhale their whirlpool hunting grounds.

When the prey reaches the whirlpool hunting ground, the cross jellyfish can use the tentacles to deliver the food to its mouth and wrist, and then use the umbrella body to digest the food.

"Brother Yang, do you think these humpback whales are dangerous?" Fang Youqun was a little worried.

Xiang Yang frowned. Normal jellyfish, even if they were highly poisonous, would definitely not have much effect on whales with thick skins.

But the cross jellyfish is different.

The tentacles of the cross jellyfish are very long, the longest tentacles can even reach tens of meters, and their toxins are intense, if the number is sufficient, it may really affect the whales.

"Don't be afraid. These whales did not move by themselves, which proves that these jellyfish should not be able to threaten them." Xiang Yang said softly.

Fang Youqun heaved a sigh of relief when he heard it, and turned to observe his cross jellyfish carefully.

Seriously, this cross jellyfish is really beautiful when swimming in the sea.

On the umbrella-shaped body of this cross jellyfish, there are beautiful patterns composed of many colors.

When this cross jellyfish floats freely in the clear ice water, it is as gorgeous as fireworks and very beautiful.

Xiang Yang also noticed that this cross jellyfish not only has a variety of colors, but also has a strong or weak purple halo on its umbrella body. When it swims, it looks like a dazzling colored ball. At the time, Xiang Yang was a little dumbfounded.

It's really beautiful.

Of course, Xiang Yang is standing on the shore by the floating ice.

If it was underwater, Xiang Yang would definitely hide how far away this cross jellyfish would have been.

Because under the beautiful appearance of the cross jellyfish, there is actually a terrifying murderous intent.

The luminous cross jellyfish can often attract many marine creatures to watch with lights.

As everyone knows, this beautiful light is actually one of the predation methods of cross jellyfish.

With its beautiful halo, the cross jellyfish can often attract a lot of prey into its hunting range, and then take the opportunity to launch an offensive, and eat a full meal without any effort.

"It's not a good thing to encounter a jellyfish." Gao Chuang touched his eyes, a little unlucky.

Xiang Yang smiled, "But there is no way, jellyfish is not so easy to eliminate, the vitality of this thing is too strong."

After Fang Youqun heard this, he was very puzzled: "It's not easy to eliminate? Isn't this just a jellyfish? Let me catch it and it will be over?"

Xiang Yang rolled his eyes, "There are only jellyfish with or without, there is no less and more jellyfish. Since there are jellyfish in this sea area, it proves that there are jellyfish in this sea area. What's the use of fishing for this?"

The life span of cross jellyfish is very short, only about two months on average.

If you don't fish for it, it won't live long.

Once caught, it cannot change the fact that jellyfish appear in this sea area.

In addition, the cross jellyfish is a very ancient creature, its origin can be traced back to 600 million years ago, it has existed on this planet for longer than the dinosaurs.

Even years cannot eliminate them. It is too difficult to eliminate them by manpower.

Even jellyfish were once suspected of being an animal.

Although jellyfish are carnivorous animals, they mainly feed on fish and plankton, but jellyfish have no respiratory organs and circulatory system, only the most primitive digestive organs, they are not animals at all.

After research, biologists discovered that the food captured by jellyfish releases digestive juice from the stinging cells on the gastric filaments in the stomach cavity, and then is immediately digested and absorbed in the coelintestinal tract.

In addition, most jellyfish are very greedy, whether they are facing various plankton, crustaceans, or fish eggs, big fish, small fish, jellyfish are all comers, and they are directly absorbed.

And it may be the reason why jellyfish only possess primitive digestive organs. UU Reading www. uukanshu.com Therefore, the jellyfish eats very fast. It only takes a few hours to digest a complete fish in time, and the digested and absorbed substances are quickly transported through the intestinal cavity.

It is this almost terrifying absorptive capacity that makes the jellyfish eat a lot of food every day to be able to maintain their life characteristics.

Therefore, all fishermen, including those engaged in aquaculture, hate jellyfish.

Ignore these jellyfish, they will multiply in the sea in large numbers, wipe out all the fish, shrimp, crabs and even plankton and fish eggs in the nearby sea, and completely deplete the fishery resources in the entire sea.

If you pay attention to them, you might be stung by this stuff.

In many fishing villages, there are staff who specialize in fishing jellyfish. They usually work in groups of two. One person row a small boat, and the other uses a hook to hook all the jellyfish that they encounter to the small boat, and then they All the jellyfish are transported ashore for disposal.

Their wages are borne by the nearby fishermen. This is a very dangerous job. Whether it is a boater or a jellyfish fishing person, they will often be stung by the jellyfish.
