My Deep-sea Fishery

The crew of the Xiangyang fleet are all looking forward to diving operations.

Because as long as they go into the water, no matter what Xiang Yang's harvest is, the crew who go into the sea will definitely get red envelopes.

It would be even better if the fishery resources in this area of ​​water happened to be good, and the crew who entered the water did not return empty-handed.

As long as Xiang Yang makes money, he will never treat the crew members who are eating on the same boat as him badly.

Soon, the crew got ready and Xiang Yang put on his diving suit himself.

"Get ready to go to sea, two people, everyone is not allowed to act alone, not too far away from the fishing boat, pay attention to safety." Xiang Yang finally reminded.

"Don't worry, Brother Yang, I can't wait a long time ago." Fang Youqun said indifferently.

Xiang Yang raised his eyebrows, and said in a low voice: "Fang Youqun, you are now the third mate on the ship, you can no longer act impulsively and recklessly as before, and set an example for the other brothers on the ship."

When Fang Youqun heard this, he quickly put away his foolish look, and said seriously: "Brother Yang, I understand, don't worry, I promise there will be no accidents."

Xiang Yang nodded, although Fang Youqun is not very reliable in normal times.

But when it matters, it is generally very reliable.

Otherwise, Xiang Yang would not choose Fang Youqun to be the third officer on the ship, and let him and Xia Pengjie assist Zhou Wang to complete the work on the deck.

In fact, Fang Youqun did take Xiang Yang's words into his heart.

Fang Youqun kept telling himself in his heart that he was now the third mate on the ship and one of the management personnel on the ship. He had to be responsible for the people on the ship and everyone's safety. Fishing for seafood was secondary. Yes, the main thing is to keep an eye on the new crew members to prevent them from getting into danger.

Don't look at the water in this sea area is not deep, and it is very clear.

But Fang Youqun is also an old crew member who often goes to sea with Xiang Yang. He knows that the more beautiful and charming the seabed is, the more dangers there are hidden. Like all kinds of highly poisonous tropical sea fish, jellyfish, etc., he likes it very much. Such a clear coral sea area.

As a result, Fang Youqun turned his head and looked around, but found that all the old crew members went into the sea this time, and there was not even a new crew member.

Although those new crew members have learned about the benefits of Xiangyang’s boat, and know that diving on Xiangyang’s boat is not as dangerous as diving in other fleets, they are still on the sidelines. Just like when Xia Pengjie and the others first arrived on Xiangyang's boat.

Fang Youqun grinned when he discovered this situation.

No new crew is better.

Without new crew members, he can concentrate on searching for all kinds of valuable seafood on the bottom of the sea.

Although Fang Youqun became one of the management personnel on the ship under Xiang Yang's designation, his thinking was still at the stage of an ordinary crew member, and he didn't think about how to find a way to make the new crew members also love diving operations .

Soon, Xiang Yang took the lead through the hanging ladder on the ship and descended to the bottom of the sea.

Just after going down to the bottom of the sea, a blue jellyfish bigger than a rice cooker floated in front of Xiang Yang's eyes.

Xiang Yang's eyelids twitched when he was frightened by this big blue jellyfish.

Such a large jellyfish can easily kill a person on the bottom of the sea.

Of course, this jellyfish is no danger to the crew on Xiang Yang's boat.

Because the diving equipment used on Xiangyang's boat is all wrapped diving suits, these marine creatures that rely on toxins to attack humans cannot cause any harm to the crew wearing diving suits.

Xiang Yang quickly swam to the jellyfish, grabbed it with his hand, and stuffed it directly into the net pocket.

Fang Youqun, who followed closely behind Xiang Yang before going down into the sea, was taken aback by Xiang Yang's actions. He hurriedly asked Xiang Yang why he had nothing to do with such a dangerous thing.

In Fang Youqun's consciousness, all jellyfish are highly poisonous creatures, and most of their bodies are seawater, so they have no food value at all.

Xiang Yang smiled slightly, if it was an ordinary jellyfish, of course Xiang Yang would not provoke it, even if it was wearing diving equipment.

But this jellyfish is obviously not an ordinary jellyfish. It is the only edible jellyfish in the entire jellyfish family, the moon jellyfish.

The moon jellyfish is a kind of jellyfish under the genus Moon jellyfish in the family Aquaphyceae.

Although the appearance of this jellyfish is blue and transparent like ordinary jellyfish, it is completely different genetically. It has four obvious horseshoe-shaped gonads. The tentacles can be used to catch prey, but the activities of the tentacles are limited. They It can only drift with the current in the ocean, and cannot swim freely.

The jellyfish body of the moon jellyfish has an umbrella-shaped membrane and tentacles attached to the bottom.

They have four distinct ring-shaped gonads under the stomach, and food enters their vertical ducts, and the radial ducts help to spread the food.

There is a layer of mesogelatin in the stomach of the moon jellyfish. There are gastric skin and epidermis in the gastric circulation cavity. The neural network is responsible for controlling the muscles and foraging responses.

In addition, the diameter of the jellyfish body can be as wide as 40 cm. Although this jellyfish has no breathing parts such as gills, lungs or trachea, it can breathe by diffusing oxygen in the water.

In the gastric circulation cavity of the moon jellyfish, they expel hypoxic water and pull in hyperoxygenated water with the action of cilia, thereby increasing the oxygen diffusion of cells.

In addition, the high ratio of surface area to volume of moon jellyfish also helps them absorb more oxygen.

In addition, the moon jellyfish lacks an excretory system and a circulatory system, and the jellyfish body can be male or female.

Planktonites have tiny ciliated cells that can swim for a day, then colonize the appropriate substrate, and transform into polyps, which divide through transverse fissures into tiny sphenoids that grow into Become a jellyfish body.

In terms of living habits, the moon jellyfish likes to eat plankton, including molluscs, crustaceans, tunicate larvae, rotifers, juvenile polychaetes, protozoa, diatoms, fish eggs and other tiny organisms.

Sometimes moon jellies also eat gelatinous zooplankton, such as hydroids and ctenophores.

The jellyfish and larvae of the genus Luna have cnidocytes that can capture prey and protect themselves. The prey will be stuck by mucus, and then sent to the gastric circulation cavity by cilia, and digestive enzymes will break down the food.

From the digestive enzymes they have, we know that they generally need carbohydrates, proteins and lipids, but little is known about the vitamins and minerals they need.

The moon jellyfish has a large number of natural predators, including sunfish, leatherback turtles, and the very large Victoria jellyfish. Moon jellyfish are also preyed upon by seabirds.

Some parasites also attack moon jellyfish.
