I have a sea in ancient times

Chapter 305 Fish Detection Sonar
After the fishing boat arrives at the pier.

The primitive people were summoned, each of them carried a fish, and first put the fish in the acid discharge room of the cold storage.

Generally, the cold storage used to store seafood and beef will have an acid discharge room.

The so-called acid discharge, in simple terms, is to discharge the lactic acid in the meat.

The general operation method is to quickly cool down within one hour after the fish dies, and control it at an environment of about 0-4 degrees for a period of time.

Usually 24 hours.

During this period, a dry oil film will form on the surface of the meat, which can not only resist the invasion of bacteria, but also lock the water and prevent it from losing.

At the same time, the enzymes in the meat will decompose the protein in the meat into amino acids during this period; myosin and myosin combine to form myosin, which finally makes the muscle contract.

This stage is called mortis.

The water retention of fish in the rigor stage is reduced, the muscle fibers are thick and hard, lack of elasticity, difficult to chew, difficult to digest, and low in edible value.

At this time, it is called raw meat.

Wait until the rigor dissolves.

It is soft to the touch. At this time, it is "cooked meat". The taste will be much better, and the meat will become soft, juicy and elastic.

The seafood that is usually used for cooking is not so troublesome. Generally, the ones that need to be drained are these large deep-sea fish.

Most tuna is eaten raw, so more attention is paid to the taste. If there is no bloodletting and acid discharge, the taste will be greatly reduced.

Lu Hai put Niugang trevally and tuna into the acid discharge room, and moved them to the cold storage at minus 60 degrees when he came the next day.

Lu Hai specially told Xiaobai that the seafood caught in general can be put in the acid discharge room.

If you must put it in a cold storage at minus 60 degrees, you must be careful, and you must wear gloves on your hands.

In the past two days, one of Star's employees didn't abide by the rules and regulations. When he entered the cold storage to carry things, he didn't wear gloves, and his hands touched the iron rack on which the products were loaded.

Due to the ultra-low temperature, the palms and flesh were 'sticked away' by the iron frame under the extremely low temperature, and they are still lying in the hospital.

Well done, after the tuna.

Lu Hai looked at the task.

Task countdown: 1 day, 10:23.

After deducting tonight, there is only tomorrow left. If you can meet a sailfish, then the mission will be completed. If not, the chain mission will fail.

It's useless to think too much, the most important thing now is to eat well and rest well.

Lu Hai grilled an abalone.Two oysters, a two-pound lobster, and some sparkling wine bought from Brother Da Xiang.

After eating and drinking.

Lu Hai suddenly remembered something, hurried back to the real world, and hurriedly called Lao Jin's phone number. He knew the most ship bosses, and he might be able to get the goods for himself in a short time.

"It's late at night, what are you calling me for?" Lao Jin, who was lying down just now, was a little impatient.

"Is there a portable fishing sonar, help me get one."

"When will it be?" Lao Jin asked.

"It's better now, or before tomorrow morning." Lu Hai replied.

Lao Jin on the other end of the phone was stunned: "It's the middle of the night, where can I get you this stuff, we'll talk about it tomorrow."

"Tomorrow will be too late. Comrade Lao Jin, please work hard. Do me a favor. I will buy the head office at a high price."

"Ugh."

Lao Jin sighed, feeling like he owed the father and son, that Lu Paotou robbed him of his old job and suppressed him to the point where he could only become the boss of the ship.

This Lu Hai came to torment him every now and then, but when he thought of how much he had helped him.

Now my son is living well on the other side of the ocean, but spending money is a bit extravagant. He really needs money.

Lao Jin got up and put on his clothes again, took some tools, and came to the pier.

"There is no portable fishing sonar, but I can disassemble it for you."

Chuan Lao boarded a fiberglass fishing boat, which was rented to others for a long time before, but now the fishery resources are scarce.

The tenant couldn't hold on anymore, so he returned it. There is a fishing sonar installed on it, which is relatively easy to dismantle.

See the boss of the boat took out tools to dismantle.

Lu Hai thought for a while, and asked directly: "Old Jin, can you sell this boat?"

Lao Jin, who was squatting, was stunned for a while.

"You want to buy?"

Lu Hai said seriously: "Don't dismantle it yet, let's make a price. If it suits you, I'll buy the whole fishing boat for you."

"Do you really want to buy it?"

Lu Hai nodded.

"For the sake of acquaintances, I'll sell you a 50 fishing boat, including all the equipment on board."

Lu Hai thought the price was okay. This fishing boat was much better than the tugboat he bought last time, and the equipment was complete. The entire hull was made of fiberglass, so it was indeed worth the price.

"The deal is the same card as last time."

Lao Jin couldn't react, so Lu Hai bought his fishing boat just like that, which was too fast.

"I'm leaving the boat too."

"Aren't you registered?"

"No, there is no need to transfer ownership."

"If you don't register, then I will cancel the account."

"can."

Standing on the pier, Lao Jin looked at the text message he had just received on his phone, and couldn't believe that 50 had just been transferred.

Looking at the fishing boat that disappeared into the sea, Lao Jin sighed, not knowing whether to call Lu Hai reckless or arrogant.

What's happening on the island these days.

He had heard about it to some extent. He had a good relationship with Lao Gao of the breeding factory. Now he would boast about how awesome his new boss was to everyone he met.

Not only are there various seafood channels, but they have also brought in a huge sum of investment.

"Ugh."

Lao Jin sighed, transferred 2 yuan to his son on the other side of the ocean, and said, "Don't save too much, just buy whatever learning materials you need."

"Thank you dad."

The other party replied in seconds.

Lao Jin wanted to reply to him: Go to bed early, but thinking about it, it should be daytime on the other side of the ocean at this time, so he didn't reply.

The next day, early in the morning.

The fishing boat sailed to the blue sea, using the land and sea fishing sonar, and found that it was really convenient to find fish.

I searched for more than four hours.

I found a lot of fish schools, including mackerel, mackerel, and even tuna schools.

But there was no sign of the sailfish, and the sound of beeps was made again with the fish detection sonar.

Lu Hai found a large number of fish schools at the stern of the boat, but when he looked back, he turned out to be a school of dolphins.

Hundreds of dolphins followed the fishing boat.

Many fishermen know that dolphins like to go with boats, but it's not that they like humans and fishing boats.

Instead, during the sailing process of the fishing boat, a pressure circle will be formed around the hull, and pressure waves and pressure flows will be generated around it.

Dolphins travel along these waves and currents with far less physical exertion.

Most of the marine organisms aim to survive. Things like this can hitch a ride and reduce physical exertion. Why not do it.

But they hitchhike like this.

Land and sea are really a headache. Where there are these things, where are there any fish? Face smart predators like dolphins.

It is estimated that the sailfish will also have to hide far away.

Lu Hai had no choice but to stop the fishing boats and wait for them to leave before looking for sailfish again.

Task countdown: 21:11.

There is not much time left for Lu Hai. Although he is ready to fail, he is still a little unwilling.
