"Brother, how can you say that? My eldest brother and sister are so good to me, why don't I think about you more?" Han Rongxia said.
"Forget it! As long as you don't count on Big Brother, that's fine. We don't expect you to be able to help," Han Kongque said.
"It's rare for me to say that I didn't help you a lot this time?" Han Rongxia said with a smile.
Han Kongque said: "It's a dispensable thing, it's the icing on the cake. With it, we will save some energy. No, it won't have much impact."
When Han Peacock said this, Han Rongxia immediately pouted.
"Okay, okay, Rong Xia has really helped a lot this time. Now it's hard to operate offshore fishing boats. In the future, there will be more choices for this kind of shrimp." Han Ronghua coaxed with a smile on his face.
Written by Han Rongxia.
"Well done, I will reward you with a big abalone tonight." Han Peacock saw Han Rongxia pouting at what he said, and immediately comforted him.
"I want a heavy single-headed abalone." Han Rongxia said immediately.
Han Kongque stared at her and said, "You really dare to think that I have never seen a single-headed abalone before! Just wait, I will look for it for you. If there is one, we will all try it."
"Brother, can you really find him?" Han Rongxia said with a surprised look on his face.
Han Rongxia has eaten a lot of seafood in the past year, so she naturally knows how rare a single-headed abalone is now. What impressed her most was the price of a single-headed abalone.
Single-headed abalone can be said to be an absolute luxury product. The price of each one is more than one million. This is really difficult for Han Rongxia to understand. It is just a bit of meat in a shell, how can it be worth millions?
Woolen cloth?
Han Peacock didn't care what Han Rongxia was thinking, he was studying the shrimp net carefully.
With this sharp shrimp fishing tool, not a single lobster in the dam can escape, no matter big or small, all are caught in the net.
"It seems that improvements are still needed. Such destructive fishing is not conducive to breeding." Han Peacock said.
"You don't have such scruples when it comes to offshore fishing," Han Rongxia said.
"You can't say that. All the shrimps in the ocean have been caught. What will we catch in the future?" Han Kongque said.
"Anyway, my shrimp net is a good thing." Han Rongxia said.
"Who said it's not a good thing? Go back tonight. I'll take you to see sharks and let you taste authentic shark fins." Han Peacock said with a smile.
Shark fins are the thin filaments of cartilage found in shark fins.
Sharks are cartilaginous fish, and their fin bones are shaped like vermicelli, but they are crisper and taste better than vermicelli.
From the perspective of modern nutrition, shark fins (i.e. cartilage) do not contain any nutrients that are easily lacking or of high value in the human body, so eating shark fins is a unique cultural phenomenon in China.
"I heard that shark hunting and whaling are both cruel." Han Rongxia said hesitantly.
"Of course it's cruel. With the development of the modern fishing industry, this kind of cruel behavior has been banned repeatedly." Liu Catkin said.
The ancients called sharks mackerel, and fish were also called sharks. They also had other names such as sea wolf, ship swallowing, and mountain swallowing. The dangers of catching sharks can be imagined, so no one in ancient times thought about catching sharks.
It wasn't until the Song Dynasty that someone accidentally discovered that the skin and lips of sharks were valuable. Some people fished sharks as amateurs. At this time, there was no professional shark fishing team. They only used large fishing boats to go to sea intentionally or unintentionally, and worked as a team to catch sharks.
In the Ming Dynasty, shark fin was born in my country, and there was a dedicated shark fishing team coordinated by shark teams, large ships, large harpoons, and large fishing nets (the shipbuilding skills of the Ming Dynasty reached its peak).
Dozens of large fishing boats and huge harpoons are the weapons of the shark fishing team. At that time, after the sharks were caught, people only cut off the fins and a few parts of the shark's body, and threw the rest back into the sea.
The specific method of hunting sharks should be similar to fishing. Later, the ships became larger, there were more people, and the fishing gear became more advanced.
Use a whaling ship with a harpoon launcher, and the harpoon shot out will hit the shark like a bullet from a gun, and then drag it up. It is quite cruel and inhumane, and very bloody.
After the shark's fins are cut off, it loses the ability to swim in the water. In order to escape legal sanctions and eliminate criminal evidence, fishermen throw the shark back into the sea. This is an extremely cruel and irresponsible act.
Sharks are cartilaginous fish and do not have a swim bladder. They mainly rely on their large liver to regulate their ups and downs. Sharks must keep swimming to let water pass through their gills, otherwise they will suffocate.
The difference between sharks and bony fishes is that they do not have swim bladders to control snorkeling. If they stop swimming, most sharks will sink. In order to reduce their weight in the water, sharks have a large amount of oil in their livers.
Han Kongque's laboratory has been studying sharks for a long time. With in-depth research, he has learned more and more about sharks. The more he knows, the more magical he feels about sharks.
In addition to the five sense organs of humans, sharks also have other organs. The most acute organ of sharks is the sense of smell. They can smell very small substances such as blood from several miles away and trace the source.
They also have a sixth sense - the ability to sense electricity. Sharks can use this ability to detect weak electric fields several feet around objects.
They can also sense vibrations caused by fish or animals 600 meters away through mechanical sensing.
A shark can produce thousands of teeth in its lifetime. Many sharks, including great white sharks, have rows of sharp teeth in their mouths. As long as the teeth in the front row are lost due to eating, the teeth in the back will be replaced. The new teeth are larger than the old ones.
Bigger and more durable.
Sharks such as dogfish and spiny dogfish will replace their entire row of teeth.
Shark's teeth are serrated, so the shark can not only bite its prey, but also effectively saw it into pieces.
This makes the shark's hunting ability extremely outstanding. If there are too many sharks, it will naturally pose a great threat to other marine life.
This is what happens now in Han Peacock's Xuanyuan Water Control Flag, such as the Great White Shark.
Because the great white shark's upper and lower jaws are not tightly connected to its head, it can extend its upper jaw upward and forward to swallow prey, sometimes even swallowing the prey in one bite.
Therefore, the few seals in the Korean Peacock Xuanyuan Water Flag have become the staple food of sharks, which is something the Korean Peacock will never allow.
Generally speaking, sharks mostly live on carrion. Sharks live on injured marine mammals, fish and carrion, culling the weaker members of the animals.
Sharks will also eat garbage and other waste thrown off the ship, but the sharks in the Xuanyuan Water Flag can only prey on other marine life inside.
Since there are very few islands in Xuanyuan Kongshui Banner, and they are all coral reefs, the seals' habitat there is very small, which makes it easier for sharks to prey on them. In addition, with the large number of sharks, seals are no match for them.
.
In addition, some sharks also prey on various marine mammals, fish and animals such as turtles and crabs.
Some sharks can go several months without eating, and the great white shark is one of them. Sometimes the great white shark only eats once every one or two months.
The great white shark is a predator that is good at camouflage. Due to its large body, it is not as agile as other sharks. However, the great white shark is an excellent hunter because it can always take it by surprise.
Its upper body is very dark and its lower body is very bright. They can use this protective color to quietly approach their prey.
When it attacks from below, because its color is similar to that of the deep sea, it will not be discovered until it attacks.
It rarely attacks from above, but when it does, the white underside blends into the bright sky reflected in the water.
This kind of hunting ability makes the sharks in Xuanyuan Water Control Flag a big scourge. The last time Han Peacock went in, he encountered swarms of sharks.
In the outside ocean, sharks do not live in groups.
"The sharks in my Xuanyuan Water Control Flag are all swarming. If we don't kill them, the other fish inside will suffer." Han Peacock said with a smile.
"You don't have a complete food chain there? I heard that there are many marine creatures that eat sharks." Liu Catkin said.
"Octopuses, especially large octopuses, can prey on sharks." Han Ronghua said.
Han Kongque said with a smile: "There is also a kind of hagfish. As long as it gets into the shark's gills and slowly burrows into the shark's brain to eat, the shark will die. Usually it burrows into the shark's belly through the gills and eats first.
Eat the meat after the offal, leaving only the skin and bones of the shark."
"It's so disgusting, please stop talking." Han Rongxia immediately gave Han Kongque a slap to tell him to stop talking.
Han Peacock said with a smile: "It's a bit wasteful to raise those creatures, but there is an octopus in the Xuanyuan Water Control Flag, but it's not reliable to use octopus to hunt sharks. Unless it's a coincidence, octopuses generally don't prey on sharks.
of."
"Then this task will be left to you. Go and get me some shark fins. I heard that shark meat can also be eaten. Don't cut off the fins and throw the shark into the sea." Han Rongxia finally couldn't bear it anymore.
The temptation of eating shark's fin once.
"Can shark meat be eaten? I have never heard of anyone eating shark meat. Is it poisonous? It would be bad if it poisoned people." Qin Mingyue said.
"You did it on purpose, right? You live in a magical city and are close to the sea. You don't know that shark meat is edible, right? Not only does shark meat not kill anyone, but eating it is also good for the body." Han Peacock smiled.
Speaking to Qin Mingyue, all she got was a pair of blank eyes from Qin Mingyue.
Just hearing about hunting sharks made Qin Mingyue a little bit intolerant, so she said this just to scare Han Rongxia and make her give up the idea of eating shark fins.
Qin Mingyue, who has lived by the sea since she was a child, naturally knows that sharks are one of the edible marine fish. Nowadays, most of the sharks sold in the domestic market are farmed sharks specially for food. Sharks are a rare aquatic product on the table, but shark fins,
But Yuchun has long been famous.
Shark's fin is tender and smooth when cooked, soft, glutinous and refreshing. It is a precious food as famous as bird's nest, bear's paw, etc.
Shark's fin is valuable because of its rarity, but it is not particularly nutritious. Perhaps compared with other foods, it is a symbol of luxury and wealth. (To be continued.)
