"I found a school of fish, get ready to work! It's probably a tuna chasing a group of stonefish."
It turned out that it was Gu Kun who was driving the boat in the cab while paying attention to the fish detector and discovered a valuable fish school.
Some people may wonder: Gu Kun obviously has excellent underwater hearing, but he hasn't even entered the water yet. How can he find fish schools that others can't?
This starts with the principle of sonar. The essence of sonar is just a wave-to-electrical converter of underwater sound. The sonar listeners in submarines also need to have strong hearing in order to hear the subtle features of the returned sound.
In this way, Gu Kun doesn't have to go into the water. Just using a receiver on the boat to listen to water sounds can increase the resolution a hundred times.
Similar to a chicken player, his hearing is so sensitive that he can hear the sound of someone climbing in the grass hundreds of meters away.
After a few seconds, everyone ran into the cockpit.
Gu Pan trimmed his hair: "Brother, what should I do?"
Gu Kun quickly assigned tasks: "Sister Chen is steering, little sister, you keep an eye on the fish detector. Long Wu will winch the net, and I will change clothes and go into the water to pull the net."
"Okay," Chen Li took the steering wheel respectfully.
However, Long Wu suggested straightforwardly: "You are the leader, so you should control the net winch on the ship, and leave it to me to pull the net in the water."
Everyone is knowledgeable, and naturally knows that the work of entering the water and pulling the net is more tiring.
Generally speaking, if it is a two-boat trawl operation, there is no need for people to go into the water to pull the net. Because the two boats can each pull one end of the trawl net, and the troops can be divided into two circuits to wrap the fish in dumplings.
But Gu Kun only has a single boat here, and the cross-sectional area of the trawl under the water is not large enough. At this time, having a good water towing can significantly increase the harvest.
If no one holds the net, fish that swim faster than the boat can escape by turning around, so only slow-moving fish can be caught.
Tuna swims very fast, with a top speed of nearly 50 knots, which is half as fast as dolphins. Therefore, catching tuna requires either sea fishing or encirclement and suppression.
It is almost impossible to catch tuna if a single boat trawls the net from one direction.
Gu Kun was very doubtful about Long Wu's swimming speed and underwater agility, and originally wanted to refuse directly.
But after thinking about it, this trip to sea will take many days. I must give him a chance to convince his boss.
So Gu Kun changed his mind: "I told you there are tuna, are you flexible enough underwater? When the time comes, the containment speed is not fast enough and the angle is not good enough, so you will just run away."
Long Wu replied straightforwardly: "Uncle Liu has hired so many crew members, and none of them can swim faster than me. If I can't catch it, you can't catch it either. Besides, why did you just say so flatly that there are tuna? This is not true at all.
Maybe you can hear it!"
Chen Li was speechless for a while: Did you talk to the captain like this?
"Haha, okay, I'll give you a chance. Anyway, there are many opportunities to go to sea this time." Gu Kun directly threw the frog web to the other party.
Long Wu didn't bother to wear a diving suit, so he only wore flippers, dragged the rope, and plunged into the water in the direction pointed by Kun Kun.
Gu Kun was observing on the boat while directing Chen Li to steer, and then controlled the trawl winch.
The two women on the boat also looked at the situation in the water with concern. When Long Wu just left and when he finally closed the net, they could clearly see the speed of Long Wu's swimming.
Naturally, Gu Kun could see clearly, and he silently calculated in his mind: "This guy's water skills are pretty good. He can swim up to five knots while dragging a rope with only flippers. Among normal sailors, his physical fitness is considered to be very good."
It’s outrageous.”
When dragging the rope, at least one hand cannot paddle, and neither hand can wear hand fins, so it cannot be compared with the speed of a fin swimming competition.
After more than ten minutes of containment work, slowly setting up an ambush, and quickly closing the net, everyone finally worked together to haul up a good net.
The harvest weight is not big, but they are some valuable fish and the size is good.
Long Wu panted and climbed onto the deck, exhausted. After all, high-intensity swimming and diving for more than ten minutes in a row consumed a lot of physical energy.
Chen Li quickly brought a bottle of cheap high-quality liquor to her husband, which could be used to drive away dampness and cold and add some calories.
Long drank three ounces of soju by the ton, wiped his mouth and asked, "What did you catch?"
While they were drinking to ward off the cold, the Gu brothers and sisters had already counted the fish, so Chen Li could answer directly:
"It's a small group of stone fish, 22 of them, weighing 58 kilograms. The largest one is four kilograms, and the small one is one and a half kilograms. There are also three green fish and a bunch of miscellaneous fish. The captain said that the miscellaneous fish will be cooked and eaten in the evening
Already."
Stonefish can be sold for 40 ling per catty in the country of origin, and the unit price of large fish is even more expensive, 60 per catty in Tsing Yi.
Therefore, these fish, which are valued at about three thousand ringgit, will be more expensive when sold to non-originating countries in the north.
Long Wu couldn't help but be jealous: "The captain's hearing is really amazing. This net is full of valuable and rare fish? This net is worth three months' salary of us and my wife?"
Chen Li: "How can the account be settled like this! There is no charge for the ship, and there is no charge for the diesel supply and maintenance."
Long Wu also knew that what his wife said was reasonable, but he still couldn't help being proud: "Anyway, the harvest from this net is very good. Tsing Yi is also a very flexible fish. I can pull all the Tsing Yi into the net, which shows that we
I'm still good at underwater skills. We'll see if the captain gives me a raise or not when the next three months are up."
"It seems that you are very confident in your performance." A lukewarm voice sounded next to him. It turned out to be Gu Kun who was walking over with his right hand behind his back after inspecting the fish.
Long Wu couldn't help but get angry after hearing this, thinking that the boss was targeting him: "Aren't you satisfied with this efficiency?"
Gu Kun: "You seem to have forgotten. I told you that I heard a tuna. Where is the tuna now? You were under the water and finally closed your head. Did you really not notice that the big fish slithered away?"
Long Wu's momentum was slightly suffocated. His vision was naturally poor when underwater, and he couldn't see clearly seven or eight meters away. However, based on the shadows and currents, he did feel that a big fish was slipping past, and the speed was not too slow.
But it’s a bit far-fetched to say it’s tuna.
What's more, he felt that the performance of this net was already very good.
Taking this kind of 200-ton fishing boat out to sea, the cost from renting the boat to depreciation to diesel, supplies, and maintenance is only 600 ling in one day. If you are not satisfied with the harvest of 3,000 ling, then the captain is too harsh.
Thinking of this, Long Wu could not help but get angry: "I think you are a cheerful person, do you dare to touch your conscience and promise that you can really distinguish tuna by sound with this kind of precision fish finder? I have traveled to sea for ten years.
I have never seen anyone with such sensitive hearing in all my years! This is simply impossible!"
Gu Kun said proudly: "Of course I am sure, because I can hear that the target is an object weighing about a hundred kilograms, and it is moving at a speed of more than 40 knots. When the two indicators of size and speed are combined, it is definitely a tuna."
Long Wu: "Hahahaha, if you insist on saying that, I can't help it. Anyway, it's empty talk. I think you are just angry that I just advised you not to do business in China, so you want to take revenge."
Seeing that they were about to have a stalemate, Gu Pan and Chen Li quickly tried to persuade each other.
Gu Pan said anxiously: "Brother, you are not usually so harsh on others. Long Wu is already working very hard."
Gu Kun gently patted his sister with his left hand and told her to calm down: "I'm not harsh, but I can't let others bully me for being young and disobeying my orders. The sea is changing rapidly, and orders and prohibitions must be enforced. If the captain has no authority,
, how can we achieve great things?"
After saying this, he decisively raised his right hand that had been placed behind his back, and a dead fish was thrown towards Long Wu with a "whoosh".
Long Wu caught it subconsciously and was too confused to react.
Gu Kun pointed at the dead fish: "Look at the bite surface and the tooth marks for yourself. Don't tell me that you have been running in the sea for ten years and you still can't recognize the mouth shape of a tuna."
It turned out that what he threw was a stone fish weighing more than three kilograms. The fish was bitten to death, and only half of the body was left.
Long Wu took a closer look and had to admit that the captain's eyesight was good, because from the look of this stone fish, it looked like it had been half eaten by tuna.
Gu Kun struck while the iron was hot, pretending to have no plans left, "You look like a reckless man at first glance, and you don't know enough about the habits of various marine creatures. How can ordinary stonefish have such a tight school?"
When I heard it on the fish finder, I felt something was wrong, and later I realized that these stonefish were surrounded and driven by large predators, so they gathered closer than usual, and we just happened to catch them all."
Long Wu suddenly felt his face burning.
What's more, this captain is also very experienced, and he combines theory with practice, like a university expert who has studied marine biology.
He is also a cheerful person. After being impressed by Gu Kun's strength, he had to admit defeat: "Captain, I was wrong just now. I was not modest enough. I have been at sea for ten years and I have never seen anyone as sharp as you. Today I
I am convinced. Please forgive me. I will work harder."
"Now that I've admitted my mistake, I won't argue with you. I'll just tell you that on my ship, you must obey all orders and prohibitions. From this time on, you will do whatever I ask you to do."
