The crew members of Xiang Yang's fleet are particularly looking forward to the diving operation.
Because as long as they go into the water, no matter what Xiang Yang's harvest is, the crew members who go into the sea will definitely get red envelopes.
It would be even better if the fishery resources in this area happened to be good and the crew members did not return empty-handed.
As long as Xiang Yang made money, he would never treat the crew members who ate on the same ship with him unfairly.
Soon, the crew was ready and Xiang Yang himself put on his diving suit.
"Get ready to go to the sea, in groups of two. No one is allowed to act alone and are not allowed to leave the fishing boat too far. Pay attention to safety." Xiang Yang finally reminded.
"Don't worry, Brother Yang, I can't wait any longer." Fang Youqun said nonchalantly.
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 like before. You must set an example for the other brothers on the ship."
Upon hearing this, Fang Youqun quickly put away his nonchalant look and said seriously, "Brother Yang, I understand. Don't worry, I promise nothing will happen."
Xiang Yang nodded. Although Fang Youqun was not very reliable at ordinary times.
But at critical moments, they are generally very reliable.
Otherwise, Xiang Yang would not have chosen Fang Youqun to be the third mate on the ship, and let him and Xia Pengjie assist Zhou Wang in completing the work on the deck.
In fact, Fang Youqun really took Xiang Yang's words to heart.
Fang Youqun kept telling himself in his heart that he was now the third mate on the ship and one of the managers on the ship. He was responsible for the people on the ship and for everyone's safety. Catching seafood was secondary. The main thing was to keep a close eye on the new crew members and prevent them from getting into danger.
Don’t be fooled by the fact that the water in this area is not deep and is very clear.
But Fang Youqun is also an old sailor who often goes to the sea with Xiang Yang. He knows that the more beautiful and charming the seabed is, the more potential dangers it contains. For example, various poisonous tropical fish or jellyfish are very fond of such coral seas with clear waters.
As a result, Fang Youqun turned his head and looked around, only to find that all those going to sea this time were old crew members, and there was not even a single new crew member.
Although the new crew members have learned about the benefits on Xiang Yang's ship and know that diving operations on Xiang Yang's ship are not as dangerous as diving operations on other fleets, they are still on the sidelines, just like Xia Pengjie and his team when they first arrived on Xiang Yang's ship.
When Fang Youqun noticed this situation, he immediately grinned.
No new crew is better.
Without new crew members, he could concentrate on searching for all kinds of valuable seafood on the seabed.
Although Fang Youqun became one of the managers on the ship under Xiang Yang's appointment, his thinking was still at the stage of an ordinary crew member. He had not thought about how to make the new crew members fall in love with diving operations.
Soon, Xiang Yang took the lead and went down to the seabed through the suspension ladder on the ship.
As soon as he reached the bottom of the sea, a blue jellyfish bigger than a rice cooker floated before Xiang Yang's eyes.
Xiang Yang's eyelids jumped with fright at the big blue jellyfish.
A jellyfish this big can easily kill a person on the seabed.
Of course, this jellyfish posed no danger to the crew on Xiang Yang's ship.
Because the diving equipment used on Xiang Yang's ship were all fully wrapped diving suits, these marine creatures that relied on toxins to attack humans could not cause any harm to the crew members wearing diving suits.
Xiang Yang swam quickly to the jellyfish, grabbed it in his hand, and stuffed it directly into the net bag.
Fang Youqun, who followed Xiang Yang closely into the sea, was frightened by Xiang Yang's actions. He immediately asked Xiang Yang with gestures and excitement why he would provoke such a dangerous thing.
In Fang Youqun's mind, all jellyfish are highly poisonous creatures, and most of their bodies are seawater, so they have no edible value at all.
Xiang Yang smiled slightly. If it was an ordinary jellyfish, Xiang Yang would certainly not provoke it, even if he was wearing diving equipment.
But this jellyfish is obviously not an ordinary jellyfish. It is the only edible jellyfish in the entire jellyfish family, except for the sea jellyfish, the moon jellyfish.
The moon jellyfish is a species of jellyfish in the genus Moon Jellyfish of the family Aequorea.
Although the appearance of this jellyfish is blue and transparent like ordinary jellyfish, it is completely different from the genetic point of view. It has four obvious horseshoe-shaped reproductive glands and tentacles that can be used to capture prey, but the movement of the tentacles is limited. They can only drift in the ocean and cannot swim freely.
The jellyfish has an umbrella-shaped membrane and tentacles attached to the bottom.
They have four distinct circular gonads beneath their stomachs, into which food enters their vertebrae, while radial water tubes help disperse the food.
There is a mesoglea layer in the stomach of the moon jellyfish, gastric skin and epidermis in the gastric circulatory cavity, and a neural network responsible for controlling muscles and foraging responses.
In addition, the diameter of the moon jellyfish can be as wide as 40 centimeters. Although this jellyfish does not have breathing parts such as gills, lungs or trachea, it can breathe by diffusing oxygen in the water.
In the gastric circulation cavity of moon jellyfish, they expel low-oxygenated water and pull in highly oxygenated water with ciliary action, thereby increasing oxygen diffusion to the cells.
In addition, the high surface area to volume ratio of moon jellyfish also helps them absorb more oxygen.
In addition, moon jellyfish lack excretory and circulatory systems, and the jellyfish body can be male or female.
The plankton has tiny ciliated cells and can float for up to a day before settling on a suitable bottom and transforming into a polyp. The polyp splits into tiny butterfly-like larvae through transverse fissures, which then grow into jellyfish.
In terms of living habits, moon jellyfish like to eat plankton, including mollusks, crustaceans, tunicate larvae, rotifers, larval polychaetes, protozoa, diatoms, fish eggs and other small organisms.
Sometimes moon jellyfish will also eat gelatinous zooplankton, such as hydromedusae and comb jellies.
The bodies and larvae of jellyfish of the genus Aurelia have stinging cells that can capture prey and protect themselves. The prey will be stuck to the mucus and then sent into the gastric circulatory cavity by the action of cilia, where digestive enzymes will break down the food.
From the digestive enzymes they possess, we know that they generally require carbohydrates, proteins and lipids, but little is known about the vitamins and minerals they need.
Moon jellyfish have a number of predators, including sunfish, leatherback turtles, and very large Aequorea victoria. Moon jellyfish are also preyed upon by seabirds.
Some parasites also attack moon jellyfish. (To be continued)
