When a person knows that there is someone behind him who is watching, the potential that is stimulated.

It is completely different from when he was leisurely and slowly farming.

Long Wu and Chen Li, when they set sail this time, not long after they went to sea, they felt that Gu Kun had a serious energy that they didn't have before.

From listening intently to every tiny echo in the fish detector, to changing into a diving suit and going into the water to check it out for yourself at the slightest clue. Every link is meticulous and very diligent.

Therefore, when Gu Kun ordered Long Wu to release the bottom trawl net for shrimp fishing, Long Wu and the others had a premonition of a good harvest.

"Looks like we won't be able to drive far this morning. If you focus on catching lobsters in the future, it is estimated that it will take more than ten days to go to sea this time, maybe longer. Long Wu put the net while chatting with Chen Li.

Chen Li's work did not slow down at all, and sighed softly: "The boss has no choice, he is targeted by Chen Mingcheng, who doesn't want to accumulate some capital and strength quickly." This net costs 8,000 orders, how can you get back if you don't do it well.

After all, lobsters are expensive, even if they are cedar lobsters, if Boss Xu receives the goods, they will not worry about sales. Napoleon wrasse, Tsing Yi, and other tropical fish, after all, the audience is narrow, and most consumers still want to pretend to be fresh. If the amount is too large, it will depreciate. ”

It turned out that this special bottom trawl for catching shrimp was also temporarily purchased when they were preparing to go to sea again in the past few days.

This time, we will be able to catch seafood such as cedar lobster, which is a specialty of the South Seas, in batches.

This kind of professional net is not cheap, 8,000 reams to convert into 20,000 yuan. However, the fishing nets are all detachable, and Liu Min's boat will not be rented in the future, and if he wants to change the boat, Gu Kun can also dismantle the nets.

When he went to sea for the first time last time, Gu Kun didn't buy another shrimp net and modify it to the boat, firstly, because his capital was relatively tight, and secondly, because the first time you were just exploring the way, he wanted to make the trip as soon as possible. Besides, if he hadn't met Xu Feng later and knew the scale of Xu Feng's business acquisition, Gu Kun wouldn't have dared to spend a lot of effort on lobsters and other categories, for fear that he wouldn't be able to sell them out.

The trawl net was soon released to the bottom of the sea, and the man who put the net could also free up one.

Gu Kun came out of the cab and ordered, "Chen Li, you go in instead of the helm." Long Wu, you watch the condition of the net alone, don't let the hook break. I'll go into the water to see what is going on, and then you can steer and adjust the towing direction and speed according to my instructions. ”

"Okay captain, don't worry. Long Chen and the others agreed.

Gu Kun changed into a diving suit, put on a headlamp, and jumped into the water.

Long Wu watched Gu Kun go into the water, made a bet with Chen Li and asked, "How much do you think this net can be dragged on, how long will it take?, can it be 200 pounds if it is dragged until noon?"

Chen Li was speechless for a while: "This is to catch the cedar dragon! It's not that kind of fish, you can make a fortune if you can have 100 pounds in a net." ”

Ryugo: "But he's the captain, he's already created so many things." ”

This "scum" is equivalent to "unbelievable" or "incredible". Long Wu was because he read the cultural class poorly, and he couldn't remember the lack of vocabulary for a while, so he replaced it with a groove.

Chen Li is more logical, and after thinking about it, she still disagrees with her husband's point of view: "The captain is amazing, of course I have seen it." His ear voice is really good, and the accuracy of listening to the fish detector is much higher than yours. But you don't know that catching lobsters and other aquatic products that stick to the bottom is not very useful. The reflection interference on the seabed is so bad, it is all mixed in clutter. ”

It turns out that instruments such as sonar are relatively accurate in direction and ranging for sound sources suspended in the water, but for things that are attached to the seabed, even if there is a sound, it is difficult to measure accurately.

This is because the impact and reverberation between the seawater and the seabed will cause great interference.

It's a bit like the down-looking radar is difficult to spot an aircraft flying close to the ground if it doesn't have a terrain cancellation function. In the water, submarines can also often avoid detection by sinking to the bottom. Especially in the sea area with a lot of corals, because the seabed terrain is inherently complex and abrupt, you don't know which ones are corals and which are other animals.

That's why lobsters, abalone, and sea cucumbers are so difficult to catch and so expensive. It's not that they're really that rare, it's because they're all attached to the seabed and hard to find. Sometimes, if the shallow sea has good light transmission, it is even up to the diver to find it visually.

Ryugo: "Of course I know what you said, but that's science, and the captain is not scientific at all." ”

Neither of the husband and wife persuaded anyone, so they set up a bargaining chip, and the two bet on smoking for a day - if the final harvest is close to Chen Li's guess, then Long Wu will not be allowed to smoke for a day, otherwise he can have two packs a day.

The couple was busy for a while, and were worried about whether they should reduce the speed of the boat again, lest Gu Kun, who was diving to adjust the trawl, not be able to keep up, but Gu Kun surfaced, jumped back to the boat, and ordered the net to be closed.

"It's okay, close the net. Gu Kun ordered while drying his hair.

Long Wu was surprised: "Closing the net? It's only been half an hour, and the speed is only 4 knots." Captain, don't you really delay a little longer? I'm afraid I won't get much out of it now. ”

Gu Kun: "It's not much, but it won't be more if it drags on any longer, hurry up and close the net so that we can speed up, I don't have so much time to waste." ”

It turned out that in this kind of trawling operation of scraping the bottom of the sea, the speed of the ship had to be slowed down.

If it is a net that catches ordinary shallow water fish, the boat can be opened for 12 knots, or even faster, because there is no need to worry about hooking a broken net or missing the net.

When the special net for shrimp and crab fishing is released, the speed of the boat is basically reduced to two or three percent of the cruising speed. This is actually very understandable, because if you drag it too fast, if the net hangs on the reef, it will be wasted.

On the other hand, the edges of these special nets are equipped with counterweight bearings and special limit hook locks, which can be dragged slowly to keep the edges of the nets in line with the seabed at all times, so that the shrimp and crabs that have been caught cannot escape. If it is dragged quickly, the terrain with large undulating depressions of the coral on the bottom of the seabed will not be in sufficient contact with the seabed, and the lobsters that have been caught in the net may also escape from this pit.

All this leads to other captains going to sea, even if the level of fish exploration is against the sky, and the divers search for shrimp schools one by one, but the problem of time-consuming and laborious trawling operation still cannot be solved, and often the lobster is gone in half a day.

Like Gu Kun, it is like hanging and forcing to point where to hit and where to strike, and it only takes half an hour to catch lobsters, so there is no comparison at all.

It's like someone sweeping a car a few hundred meters apart with a big pineapple, so you have to pull the trigger and shoot all the 100 rounds out of the magazine.

And in Gu Kun's hands, he used the big pineapple as a sister control, and stopped after sucking 20 shots, and confidently collected the gun like the Beidou God Fist, adding "You are dead".

Long Wu took the net back suspiciously, and when he dragged it to the position just out of the water, he felt the heavy resistance in the net.

The old sailor can hear the weight of the harvest in the net by listening to the sound of the winch motor.

The fishing net was finally completely dragged out of the water, and Long Wu and Chen Li were amazed when they saw it:

"So many lobsters!"

"There are so many kinds of flounder! hundreds of pounds. ”

It turned out that in addition to cedar lobsters and pipi shrimp, there were also many tropical fish such as flounder attached to the coral sand on the bottom of the sea. Many of them are colorful, and some have long, showy flippers.

Not all of these fish are delicious, but the vast majority are delicious. The key is that it is very beautiful, if it can be raised in a living water tank until it reaches the shore, it can be sold as an ornamental fish.

And if it weren't for the kind of special nets that can scrape the seabed directly in the coral reef landform, these fish are difficult to catch in batches.

Both Long and Chen felt that the new net that the captain spent money on this time was too worthwhile.

Only Gu Kun himself knows that his success cannot be replicated, and if he is replaced by someone who has not been hanged, even if he has a good network, he will not have such a good harvest.

He was sure that he would do so.

Before going to sea this time, he felt that his grasp of the potential of this body had deepened. The first is his hearing, which can be heard and perceived by diving quietly for a period of time in the same shallow waters.

Then, he could pick out any echoes that were slightly different from the original terrain, knowing that there were sea creatures lurking there—in a word, his hearing was like a normal sonar with terrain contrast turned on.

Who made his ears the black technology of 2019, slowly adapting and exploring the potential, and always digging out more awesome performance details than the most advanced sonar in the 90s.

It is estimated that it will take a few months of adaptation and training, and it will be no problem to rely on this hanging skill to find ancient shipwrecks and salvage them in the future.

In addition to hearing, Gu Kun further discovered this time that his underwater eyesight was also much stronger than in his previous life.

This is not to say that his farsightedness resolution is stronger, but only that the viewing distance in a low-light environment is far away. A normal person may go 30 meters underwater without the help of a diving headlamp, because the sun does not penetrate the deeper seawater, and nothing can be seen. And Gu Kun found that as long as he concentrated and focused, it seemed to be no problem to go twice deeper. As long as the coral can grow, he can basically see it.

This also means that after he returns to the shore, his eyesight during the day is not much better than that of a normal person, but his night vision ability at night will be very exaggerated, like installing a simple version of a low-light night vision device.

All this has created his boring and boring harvest at the moment.

"Captain, it has been counted, there are more than 70 cedar dragons, more than 200 pounds, 350 pounds of tropical fish of various flounder genera, 170 pounds of southern mussels, 120 pounds of stonefish, a bumper harvest.

The lobster wholesale to Boss Xu is 50 yuan a pound, the stonefish is 100, and other flounder genera are cheaper, and these add up to 30,000 or 40,000 yuan, how long has it been. ”

After counting the harvest, Long Chen's admiration for Gu Kun increased to another level.

Gu Kun smiled lightly, and encouraged morale: "What is this, keep going." This time I'm hurting well, we're going to do a big job, I don't want to waste a day. Especially before we get to the Wissee Islands, there are a lot of tropical fish, and we have to take every opportunity. ”

(Today's second watch will not be sent until noon.) It's a new week, and it's finally recommended, asking for a recommendation ticket and a guaranteed reward of 1 yuan/person. Alas, it's time for a book to "prove to the editor that I'm still useful." It can also be regarded as a self-examination to see how the audience of this subject is. Please be sure not to fatten, keep chasing more, I will speed up the pace after the push, thank you. ）
