Chapter 103 Fish Finder Improvement

The old fisherman who followed him heard what Wang Jiankun said and quickly operated the machine to lower the fishing net into the sea.

Wang Jiankun felt relieved when he saw his skillful operation. To be honest, he had no idea how to put such a big fishing net. Although he had asked Captain Zheng before, he explained it very simply. Just like that, the fishing net was lowered to the bottom of the sea.

Wang Jiankun was still confused after hearing this, so he decided to ask Liao Jun to invite an experienced fisherman to come on board to help with fishing.

Fortunately, he was there, otherwise it would be difficult for Wang Jiankun to operate alone.

After the fishing net was lowered, Wang Jiankun used his superpowers to observe the movements of the fish while driving the boat to chase the school of fish. Because the boat was faster than the fish below, after about 10 minutes, the fishing net caught the fish.

Seeing that most of the fish had entered the net, Wang Jiankun quickly asked the old fisherman to pull the net up.

When the old fisherman heard that he was in such a hurry to pull up the net, he said quickly, "Boss Wang, the net was just cast down not long ago. It would be better to wait another hour before pulling it up. Otherwise, there won't be many fish in the net. It would be a waste of time and diesel!"

"Old Yu, listen to me. The fish finder on my boat has detected a school of fish. It is estimated to weigh at least 5 kilograms, and it is likely to be large yellow croaker. We must quickly pull up the net to check, otherwise it will be crushed by the fish that enter the net later."

When the old fisherman heard him say this, he felt very strange, wondering how the equipment could be used to see schools of fish under the sea. Moreover, the boss said that they might be schools of yellow croakers.

But he did whatever the boss said. He was paid high wages, 10 yuan per trip out to sea, which was more than three times what other fishing boats made. He just hoped that the boss would hire him for a few more days.

After the veteran fisherman started the net-pulling machine, Wang Jiankun also slightly slowed down the boat speed, while also paying attention to avoiding other fish on the seabed, because his main purpose was not to catch fish, but to improve the fish finder. Once the improvement was completed, he could form a fishing team to carry out targeted fishing.

The fishing net was quickly pulled up under the control of the old fisherman. Seeing that the bottom of the net had reached the sea surface, the old fisherman asked Wang Jiankun to stop the boat and prepare to use the fish bag to lift the catch onto the boat.

Wang Jiankun performed this operation very carefully because he was afraid that the fishing net would be rolled into the machine due to improper operation.

When the fish bag was brought onto the deck, the veteran fisherman discovered that the net was full of golden fish, which looked like yellow croakers.

Currently, the price of this fish in Shanghai Jinshan Fish Market is 1 yuan per catty for 2 to 1 catties, 2 yuan per catty for 4 to 2 catties, and it is more expensive for those above 4 catties, and it is also very rare. Sometimes if the amount caught on the same day is small, it can be sold for 7 or 8 yuan per catty, and if the amount is large, it can be sold for about 4 yuan per catty.

When fishmongers distribute the fish to various vegetable markets and hotels in the city, the price will increase by 1 or 2 times, and the larger the fish, the higher the price. Even during the yellow croaker season, the price remains very high.

According to Liao Jun, this kind of fish was still very cheap five years ago, only 5 or 1 cents per pound, and the quantity was also large. But in 2, many people began to contract fishing boats, and then they fished too aggressively, resulting in a significant decrease in production during the flood season each year, and each year is less than the previous year, so the price is getting higher and higher.

Of course, this is also somewhat related to the low reproductive capacity of this fish. For example, the hairtail here is caught in large quantities every year, and the output does not drop much during the flood season.

After opening the fish bag, the old fisherman was so shocked that he was speechless when he saw the net full of rhubarb that filled half the deck.

"Hey, Lao Yu, come back to your senses. Hurry up and put the fish away and put them in ice. The quality will deteriorate if left for too long." Wang Jiankun called out to the shocked old fisherman.

"Hey, okay, Boss Wang, you may look like a novice fisherman, but you are quite good at fishing. This net is exactly what you said, a school of big yellow croakers!"

"The sonar fish finder on my boat is very useful. I just saw a school of fish on the sonar, and then I analyzed that there is an 80% probability that it is a school of yellow croaker, so I asked you to cast the net quickly."

"This sonar fish finder is really good. Boss, is this machine expensive?" said the old fisherman while sorting yellow croakers.

"There are several models of this machine. The most basic one can detect fish schools within a radius of 50 meters and about 100 meters below the sea surface. It costs 1000 yuan each. There is also a model that can detect fish schools within a radius of 100 meters and about 300 meters below the sea surface. It costs 1500 yuan each."

"1000, 1500? That's too expensive. I heard before that a 16-meter motorized fishing boat only costs about 3000 yuan. This machine is worth half the boat. Those boat bosses may not be willing to buy it!"

"It's okay. They just don't know what's good. This sonar fish finder can not only tell whether there are fish below, but also roughly identify what kind of fish it is. This will greatly speed up fishing efficiency. Look at my targeted fishing. Isn't it much better than Captain Zheng's luck of finding a needle in a haystack?"

After listening to the old fisherman, he thought for a while and said, "Boss, what you said does make sense. It seems that this sonar fish finder is really worth the money!"

Wang Jiankun heard that he wanted to own a fishing boat instead of working as a boatman for others, so he asked, "Old Yu, if the Hong Kong Fisheries Company cooperates with you, would you be willing?"

"Cooperation, how can I cooperate? I don't have much money now, so I can only do this much!"

"You have rich fishing experience, you know this sea area very well, you know the best time and place to fish during the flood season, and you are familiar with the equipment on the boat. These are all very valuable."

"Boss, now that you mention it, I seem to have quite a bit of capital. Can I cooperate with the Hong Kong fishing company you mentioned?" the old fisherman asked unconfidently.

"I was sent by this fishing company to conduct an inspection. You can work with me for two more days and tell me everything about the situation here. I will apply to the company after returning to Jinshan. It should be possible. You don't have to worry about the benefits. It will definitely be more than what you earn on other ships, and it will be very stable. Even if you are not at sea, you will still get a basic salary."

"Hey! Thank you for your help, boss. I am willing to cooperate with the company."

As they were talking, the fish scattered on the deck were sorted, put into bamboo baskets and chilled with ice.

This old fisherman is really efficient at his work. The big yellow croakers are packed into baskets according to their weight and stacked up separately. Other fish weighing around 40 kilograms are also packed into separate baskets.

王建昆数了下，大黄鱼中有12条是6斤以上的，4到6斤的有36条，2斤到4斤的有62条，1斤到2斤的126条，半斤到1斤的有200多条，总共大概有7百斤，比王建昆估计的还多一点。

If all these fish were sold at Jinshan Fish Market, this net would earn about 1500 yuan, which is equivalent to a week's fishing for others.

The old fisherman knew he would make a fortune with this net when he was sorting them. Now that he has calculated it, he feels that the sonar fish finder the boss mentioned is really useful. Even though it is expensive, it is worth it. Not to mention catching a school of yellow croaker every day, if he can catch a school of yellow croaker in a week, that would be a fortune!
Moreover, according to the boss, many kinds of fish can be identified, so targeted fishing can be carried out, and the efficiency will be greatly increased. When he thought of this, he was even more looking forward to the cooperation with this Hong Kong fishing company that the boss mentioned.

After moving all the fish to the insulated ice room, Wang Jiankun continued to drive the boat towards Captain Zheng. He kept the fish finder on during the trip and also used his super power to keep an eye on the fish situation on the seabed.

Because the information of the yellow croaker had been analyzed and updated in the sonar detection system, information of the yellow croaker would be detected from time to time along the way. Wang Jiankun would use his superpowers to confirm and strengthen the correct information and eliminate the wrong ones.

After more than half an hour, the accuracy of the fish finder in detecting yellow croaker was close to 90%, and Wang Jiankun decided to solidify the data.

Because the fish detected were only very small schools of yellow croaker, Wang Jiankun felt that time should not be wasted, so he did not let the old fisherman cast the net.

Of course there were other fish as well, but they were not very single and were rather mixed. Wang Jiankun decided to wait until he encountered a relatively single school of fish before casting the net to catch them, which was also to facilitate data recording.

When it was almost 3 o'clock in the afternoon, Wang Jiankun finally saw a large school of fish, which was about 60 meters long. Looking down at the sea from the cab, he could almost see a long shadow moving under the sea.

Wang Jiankun operated the fishing boat to follow the school of fish, asked the old fisherman to cast the net, and recorded the data of the school of fish. At the same time, he called Captain Zheng on the radio, telling him that there was a large school of fish here, and if the net had not been cast yet, he should come and cast the net quickly, because Wang Jiankun calculated that his net could only catch one-fifth of the fish, and if it caught more, the net lifting machine would not be able to lift the net.

Captain Zheng was just about to cast the net when he heard Wang Jiankun shouting on the radio that there was a large school of fish. He quickly replied that he would be there soon and asked Wang Jiankun to take it easy and not to scatter the school of fish.

At this time, Captain Zheng's ship was only more than 1 nautical mile away from Wang Jiankun's, and it was approaching very quickly. Wang Jiankun therefore slowed down the speed a bit and waited for Captain Zheng to arrive before trawling side by side.

"Boss Wang, are the fish in front of you? Can you see the fish?"

"Captain Zheng, the fish school is right in front of me. Please align your boat with mine, about 15 meters apart. After we drop the net, we will speed up together. Look at the direction I'm heading and follow me. I guarantee you'll fill the fish hold with one net."

"Okay, Boss Wang, I'll listen to you. I'll adjust my position and cast the net right away."

As he spoke, he adjusted the driving of the fishing boat to sail side by side with Wang Jiankun's fishing boat, and at the same time directed the boatman to cast the net quickly. He was also afraid that if he took too long he would lose the school of fish or that the fish would be frightened and scattered.

After Captain Zheng's fishing boat had lowered the net, Wang Jiankun asked him to help increase the speed of the boat, and reminded him from time to time to turn or adjust the depth of the net.

When the fishing net caught the school of fish, Wang Jiankun clearly felt that the resistance of the boat had increased. Captain Zheng also shouted: "Boss Wang, we have caught the school of fish. They should be entering the net. Now the resistance of the boat has obviously increased."

"Yes, my sonar fish finder has shown that the fish has entered the net. At this speed, we should start to raise the net in ten minutes. I'm afraid the net lifter won't be able to lift the net."

"Will you raise the net in ten minutes? Why not chase them a little longer and catch more? It's still early."

"Captain Zheng, there is only one boatman on my boat. If the net is too heavy, the net-lifting machine may not be able to lift it."

"It's okay, Boss Wang. Just keep directing the fish. No matter how many fish you catch, don't be afraid. I have a lot of boatmen on my boat. They can help you put the fish on the boat in batches using nets."

"That's fine, but the fish school is huge. Don't let too many of them go into the net, or the fish hold won't be able to hold them all."

"It's okay. If the fish can't fit in the hold, we can put it on the deck. If that doesn't work, we can drag the net behind the ship into the harbor. Once we get to the harbor, we can ask a small boat to help net up the fish."

"Okay, Captain Zheng, you're really hardworking. Follow my instructions and move forward. This net will definitely exceed your imagination."

So Wang Jiankun drove the fishing boat and followed the school of fish. The school of fish felt uncomfortable with the two creatures that were following them and making loud noises, so they would change their direction from time to time.

However, Wang Jiankun was able to see the changes in the direction of the leading fish in front of him from the sonar fish finder, and his superpowers also assisted in observation, so he did not lose them.

It was not until two-thirds of the fish had disappeared that the remaining fish under the sea sensed something was wrong and began to split into small groups and swim in different directions.

Wang Jiankun had no choice but to face the situation. There were a large number of fish in the fishing net, so the speed of the fishing boat could not be increased. It was also difficult to chase the fish after they were dispersed because the direction changes were faster and more flexible.

"Captain Zheng, we have already caught two-thirds of the fish. Seeing that the situation is not good, the remaining ones have split up and are swimming in different directions. Let's start fishing now. It will take a long time to get the fish from the net onto the boat."

"Okay, the diesel engine of my boat has been increased to maximum power, but the speed still can't be increased. I guess it's too slow. Let's slowly slow down while collecting the fishing nets."

So the two boats separated a little, and at the same time, the net-lifting machines began to pull the fishing nets with a clicking sound.

Wang Jiankun controlled the boat to slow down slowly while observing the old fisherman operating the net-lifting machine.

"Boss Wang, this is a great catch. Look at the net machine. It's so slow. We may not be able to get it on the boat later."

"It's okay. Try to make the net as short as possible first, so that it won't get stuck on the bottom when you stop. If you can't lift it up, use the fish-gathering net to get it on board little by little. Captain Zheng's crew will come to help you later."

"That's good. I can't handle all these fish by myself. It would be much better if someone can help me."

As the fishing net was gradually pulled up and got closer to the sea surface, the old fisherman became excited. Captain Zheng was also very excited because he saw a big bag full of fish, and almost all of them were small yellow croakers.

He estimated that such a large bag of fish must weigh about 2 kilograms. Now is the end of the yellow croaker season, so the price is much higher than during the season. It can be sold for about 1 cents per kilogram in the fish market. Roughly speaking, this net can be sold for about 5 yuan.

He couldn't help but be excited. He could earn a boat with this net. After selling the net, he could buy the boat.

After the excitement, he asked the boatman to quickly use the fish collecting net to lift the fish onto the boat. However, because the fish were too heavy, the net lifting machine was almost smoking at this time, so they could only use small fish collecting nets to lift the fish onto the boat one by one.

After Wang Jiankun parked the boat and sorted and analyzed the information of the small yellow croaker and entered it into the sonar detection system, he also helped to collect the fish under the command of the old fisherman. Because there were so many fish, the old fisherman had to collect them all by himself until late at night.

Captain Zheng was also helping to collect fish on a nearby boat at this time, while also chatting loudly with Wang Jiankun.

"Boss Wang, your sonar fish finder is really amazing. It seems that I was short-sighted before. After I sell the fish, can I ask you to buy a sonar fish finder?"

"Sure, Captain Zheng, but the one I introduced to you before, which costs 1 yuan, can't distinguish the types of fish. The one I use on my own boat now is our company's most advanced one, which can distinguish most commercial fish. This morning I used it to detect a school of yellow croaker and caught about 7 kilograms. If we go to Jinshan Fish Market, the yellow croaker we caught can be sold for about 1500 yuan."

"Ah? You used a sonar fish finder to track down a school of yellow croaker this morning? You caught more than 7 kilograms of yellow croaker? My goodness, Boss Wang, how much does that top-grade sonar fish finder you mentioned cost?"

"Our company is offering discounts and promotions, so I can give you 1500 yuan per unit. After the promotion period, it will be 2 yuan per unit."

"1500 yuan per unit? Will it increase to 2000 yuan after the promotion period? Then I will order one from you now, and I will pay you after I sell this batch of small yellow croakers. When can I get the sonar fish finder?"

"It will probably be available on the 7th. If you have friends who need it, please introduce them to each other and I can adjust the stock for you. Otherwise, you may have to wait for a while. I may also adjust the price to 2 yuan."

"Number 7? Sure. After I sell the fish tonight, I'll introduce it to my relatives and friends. I don't know if they're willing to buy it, but I'm sure I'll buy it."

After Captain Zheng agreed with Wang Jiankun to buy a sonar fish finder, he stopped talking and concentrated on collecting the small yellow croaker.

The fish collection lasted until after 9 o'clock that evening. The bamboo baskets that Wang Jiankun brought were only enough to hold 8 kilograms of small yellow croakers. The remaining 3 kilograms were scattered in the cabin, and more than 1 kilograms were also scattered on the deck. The boat was so full of small yellow croakers that there was no place to step.

When all the fish were on board, both boats started to rush towards Jinshan Fish Market.
