"There are no injuries to the fish, and it's not because of a lack of oxygen. Pen~Fun~Pavilion www.biquge.info So how did it die?" Shuichi Minamino lay on his chair and couldn't think of a reason why his head exploded. He has been out fishing for a few days, and he has known that there are some fish in the ocean that are more special, also called ashore death. That is, as soon as you go ashore, you will die in less than a minute.

But this wrought-iron butterflyfish doesn't look like the kind of fish that dies when it comes ashore. If that's the case, how can you sell ornamental fish? If you go ashore and die instantly, this kind of fish will definitely not be used as an ornamental fish. As an ornamental fish, it dies immediately when it is salvaged, how can it be sold to those buyers?

Shuichi Minamino, who couldn't figure it out, knew that he continued to experiment, and he planned to try a few more times to verify where it appeared!

"Deep-sea hunting beasts, catch another one this time. Remember to be gentle, drop slowly, and don't hurt them!" said Shuichi Minamino to the deep-sea beasts.

The deep-sea hunting beast seemed to feel that its master was very serious at this time, and it also knew the powerful relationship.

So it slowly approached the wrought iron butterflyfish, and then gently netted one of them into it with a net bag. After the net is entered, it slowly swims to the side of the fishing boat.

During this period, Shuichi Minamino also switched visuals to pay close attention, and it was a little funny to see the gentle movements of this big guy. You can imagine this big guy like a hill doing this with clumsy actions, and it's cute to listen to it.

At this time, the deep-sea hunting beast was still 2 nautical miles away from the fishing boat, and it did not dare to swim too fast, because its master told it not to shoot a gun, but to work quietly.

The deep-sea hunting beast slowly floated up from the sea more than 100 meters deep with a net bag, and it planned to float to a depth of several tens of meters before heading straight to the fishing boat.

Shuichi Minamino now stared at the wrought iron butterflyfish in the net pocket with wide eyes, staring closely at the black jewel-like butterflyfish. At this time, the fish was shrouded in the net and looked unusually panicked, and it scurried left and right in the net to escape. But the net pocket can actually escape?

"Well, it's not dead yet. Shuichi Minamino stared at himself and muttered, it was still jumping around.

As the deep-sea hunting beast slowly ascended, it reached a depth of more than 100 meters to 100 meters.

90 meters deep ......

80 meters deep......

As the deep-sea hunting beast ascended, Shuichi Minamino found something that shocked him, that is, the wrought iron butterflyfish seemed to become a little painful as it rose, and the original lively struggle turned into a sluggish feeling.

When he reached a depth of 70 meters, he was surprised to find that the wrought iron butterflyfish was a little more bloated than before, and it seemed to be dying!

When it reaches a depth of 50 meters, it seems to have lost its breath of life, and even the belly of the fish has turned over.

"Nima, it's dead!" Minamino Shuichi was dumbfounded.

"Just dead?"

"What's going on!"

Minamino Shui's face was stunned, he watched this wrought-iron butterflyfish die. It knew that the death of the wrought-iron butterflyfish had nothing to do with the deep-sea hunting beast. Because it didn't touch it.

"And how the hell did it die?" said Minamino Shuichi, lost in thought.

"Before it died, it slowly became weak from liveliness, as if it had suffered a great deal of pain. Its body slowly became bloated. At the end, it seemed to have a feeling of exploding...... "This is the change he just observed."

"Deep-sea hunters, throw away the fish. Grab another one. Remember, it must be slower than just now!" Minamino Shuichi commanded the pair of deep-sea hunting beasts. In the dark, he seemed to grasp a trace of inspiration and doubt. But when he tried to figure out why, he couldn't!

After the next few experiments, it was the same as the previous one, and the wrought iron butterflyfish hung up before it came out of the water.

"Smack!" Shuichi Minamino suddenly patted his head and shouted, "I know, I know the reason for their death." It must be because of the water pressure! They are deep-water fish, and if you get from the deep water to the dive area quickly. The sea pressure must change from large to small. The pressure is different, and the pressure on wrought iron butterflyfish is definitely changing. In this way, it suddenly goes from the pressure to which it was adapted, to the environment to which it is not adapted, and there will definitely be problems! That's why it died. Minamino Shuichi said secretly in his heart. No wonder he noticed why the fish's body slowly became bloated and swollen as it floated. That's because as the pressure of the sea water decreases, it doesn't adapt, causing its body to open and explode on its own!

If it is a large fish, such as tuna and sperm whales, there will be no such problems at all. They are large, and this change in sea pressure is not fatal to them.

But this wrought iron butterflyfish is only the size of a palm. Such a problem arises when its body's endurance changes too quickly.

"It seems that the speed of the deep-sea hunting beasts is too fast, causing these wrought iron butterflyfish to hang up directly without adapting to it. "Shuichi Minamino found the reason.

"Deep-sea beasts, grab two and try again. This time you have to go up slowly, at your slowest speed!" Minamino Shuichi commanded the pair of deep-sea hunting beasts.

Soon the goods were ordered to leave. After directly netting two wrought iron butterflyfish with a net, it slowly floated up, and this time it floated N times slower than the previous times. Well, it should be described as turtle speed.

This time, Shuichi Minamino is still paying close attention to the movements of the wrought iron butterflyfish.

Sure enough, as the deep-sea hunting beasts floated up and down at the speed of the turtles, the two wrought-iron butterflyfish did not die, although they were uncomfortable! The ones who died before were all because the deep-sea hunting beasts floated too fast, causing them not to adapt to the pressure of the seawater and directly supported themselves to death.

"Haha, now the problem is solved. Shuichi Minamino smiled. He then ordered the deep-sea beasts to catch all the remaining wrought iron butterflyfish.

After a few hours of work, the deep-sea hunters caught a total of 40 wrought iron butterflyfish.

Above the fishing boat, there is a large glass fish tank with an oxygen supply machine providing oxygen. There are 40 wrought iron butterflyfish in the fish tank. At this time, these small fish are very active swimming around this big fishing port.

"Wow~ It's so beautiful. The two daughters of Iloti stood on both sides of the glass fish tank, staring at the fish in the fishing harbor with a pair of beautiful eyes.

"It's a precious ornamental fish, it's really beautiful. "Shuichi Minamino is also very fond of these fish. They are as beautiful and noble as the black swans among the fish! they are like a nobleman who makes people deeply loved.

"When the time comes, I'll buy a big aquarium when I go back, and I'll keep two!" Iloti waved his hand with a pink fist.

"No problem. Shuichi Minamino readily agreed, and this time he caught 40 fish, and he planned to sell 30 and raise two himself. Put another 8 to go to their own fishing grounds to breed. However, these fish are relatively expensive. He plans to get a separate cage for farming. If he is placed in the fishing grounds, not isolated in cages, and eaten by other big fish, he will lose a lot.

He knows that the conditions for raising this fish are harsh, and the sea temperature it needs is between 16 and 22 degrees, and if it falls below or exceeds these two temperature values, they will die. But the temperature of Shuichi Minamino's fishing grounds can be intelligently adjusted. At that time, the system will definitely adjust the appropriate temperature for them to live in the sea area where they live. That's perfectly fine.

If there is a lot of plankton in another fishing ground, there is no need to worry about their food.

After catching these fish, Minamino had no intention of looking for other fish. Instead, they hurried back to Nemuro Fishing Port. He was afraid that the fish would be left in the fishing port and he didn't know if there would be problems or death. Anyway, he hurried back now and sold them to Lip, they were the safest way. They must have a relative way of breeding ornamental fish companies.

At this time, it was only 100 nautical miles from Nemuro Fishing Port, and in the afternoon, Minamino Shuichi's fishing boat returned to Nemuro Fishing Port.

After returning to the fishing port, Shuichi Minamino took 5 fish directly to the purchase and trading street of Nemuro Fishing Port. Because he knew that the American Imperial Ornamental Fish Sales Company had set up a branch here a few days ago. The people in it are Lip and Cage. He didn't bring it all with him, because it was too expensive, and he was afraid that something would go wrong if he brought too much at a time.

When Shuichi Minamino and others came to this store with fish, he saw that this store was very large and decorated in a very stylish manner, and after entering, he also found that there were more than a dozen aquariums of all sizes inside. There are also some fish in it.

It seems that this store not only buys ornamental fish, but also sells ornamental fish. The decoration is so luxurious, and there are fish in it, which must be used for sale. It looks like a two-in-one storefront.

There were two welcoming girls standing at the door. When he and his second daughter arrived, the two welcoming girls welcomed them in with a smile. When I entered, I saw Lip and Cage talking to a few people. When Shuichi Minamino saw those people, it seemed that they were fishermen from Nemuro Fishing Port.

"Yo~ Isn't this Mr. Minamino?" Cage saw this very much, and immediately greeted someone when he saw someone coming in. When he saw that it was Shuichi Minamino, he was also surprised.

"Cage, this time you have a business. Shuichi Minamino grinned.

At this time, Cage noticed that two sailors behind Shuichi Minamino were holding a small glass fish tank, both of which contained fish.

His eyes widened when he saw the wrought iron butterflyfish in the fish tank that were as bright as jewels!

"Oh my God, it's a wrought iron butterflyfish!" Cage said in shock.

His shouting caught the attention of Lipp on the side, and the local fishermen who were talking to Lipu also noticed the situation and surrounded him.
