Night.

Yang patrolled them on duty.

Chen Yuan: They went to the Xinhai.

It is really uncomfortable to be on a small fishing boat for a long time, and occasionally go to a large boat to breathe.

Rushed overnight, and the next morning, stopped the boat for dinner.

Chen Yuan also changed shifts with Yang Xun, and they were already on the north side of the Bass Strait, where the flow of sea water was obvious.

"How?" Zhou Sheng saw a fishing boat not far away and asked.

Chen Yuan took out the drone and flew it around, and there were obviously a lot more biological signals in this sea area: "The fishing boat on the opposite side is a gillnet? ”

"It should be." Zhou Sheng shrugged.

"Let's go somewhere else." Chen Yuan controlled the drone and flew north.

Zhou Sheng lifted the throttle and kept up with the drone.

The drone flew for more than half an hour, and when it was about to take back the drone, it suddenly received a large number of biological signals.

"I found it." Chen Yuan pointed in the direction to Zhou Sheng, remotely controlled the drone back, and waited for the ship to stop and replace the drone with a set of batteries, and continued to release the drone.

It's been so long.

Zhou Sheng also understood the working principle of remote sensing fish scouting.

Organisms emit electromagnetic waves, which are received by remote sensors and fed back to the display.

The advantage of remote sensing fish scouting is that the perception range is large. There are also disadvantages, you can't tell what kind of fish it is, and you can't even tell the approximate size of the fish.

Even a large school of tuna is no different from a school of small fish in the eyes of remote sensing fish scouts.

You can only see how much, you can't tell the size.

But just one has a large perception range, and this thing is an artifact.

As for reconnoitering the location of the fish, it is necessary to reduce the altitude of the drone to find the signal source.

Once you find a school of fish, you can calculate the size of the fish using the fishing boat's fish finder.

The fish exploration of the Shengyuan fishing boat is still very good, and it can be accurate to about 10 centimeters. This is much better than the radar fish scout used by fishing boats.

The signal source of remote sensing fish is densely packed, and it is a large school of fish.

But through the observation of the drone, Chen Yuan found that the fish were not concentrated, so he took the walkie-talkie: "Master, speed up." ”

"Found tuna?"

"I guess it's a school of flying fish." Chen Yuandao.

"What's the deal with the flying fish." Luo Laosi's voice came out.

"A big school of flying fish. The schools of fish are somewhat scattered, preferably with tuna purse seine nets. ”

"How big is it?"

"There are tons of nets."

"I don't want to do flying fish, it's too cheap." Lin Xinhai said. Frozen flying fish is very cheap, with a wholesale price of about five yuan per catty.

A few tons of flying fish are not worth a few dollars.

Lin Xinhai is now full of tuna, and he doesn't want to engage in any fish except tuna.

"There's flying fish, and there's usually tuna, so hurry up."

"It's already the fastest."

Since cooperating with Chen Yuan and them, Lin Xinhai doesn't like to use his brain now. He's also a captain of a ship.

Tuna like to eat flying fish, a large school of flying fish, which can easily attract tuna to come.

Chen Yuan: They haven't reached the top of the fish yet, so they don't know if there are any tuna. If you're lucky, you might end up with a big school of tuna.

"Shall I come here?" Luo Laosi asked.

"Just take your time, turn on the radar and scout. This school of fish is very scattered, and you can catch a net if you come over. ”

"Okay, I'll go over slowly."

The Xinhai was at full power, and it only ran a little more than 14 knots, just like an old lady walking.

The Shengyuan fishing boat had already come to the vicinity of the fish, Chen Yuan quickly put the drone back, took over the pilot's seat, and adjusted the fish exploration picture.

The vertical line shows that schools of fish are concentrated within twenty meters and that no large fish are seen.

Chen Yuan drove the fishing boat to the back of the flying fish, and finally a few big fish appeared on the screen. Seeing this, Chen Yuan suddenly became excited: "Master, there is tuna." ”

"It's coming, it's coming." Lin Xinhai said: "How much? ”

"Now there are only three of them, this school of fish is too scattered, there must still be one."

Zhou Sheng patted Chen Yuan, and a few relatively large fish appeared in the picture: "What kind of fish is this?" ”

"It's supposed to be a ghost-headed knife." Chen Yuandao.

The shape of the fish cannot be displayed on the fish finder screen, only the length.

I just saw a few 'tuna', all of which are more than 1.5 meters long.

And now the several big fish that appear in the picture are 0.5 meters to 0.7 meters long, and it is estimated that they should be ghost head knives. Of course, in addition to the length of the fish, judging whether these fish are ghosts or a reason is the movement of the new big fish in the past few days.

If it's a tuna, it's not likely to do this kind of movement when it's not frightened.

There is a more important reason, there are many flying fish in this area, and there are also many ghost head knives.

As for tuna, it's really a matter of luck.

In the South China Sea, it is not uncommon to have 100 tons of tuna in a net, but it is not necessary to encounter it once a year.

Chen Yuan naturally has expectations, a net of 100 tons, or even 200 tons.

People always like to dream, and they have to have a good wish.

Chen Yuan reconnoitred a group of fish on the periphery, and only saw 7 large fish suspected of being tuna, then pulled down the throttle of the fishing boat, maintained a low speed, and drove the fishing boat into the center of the school.

"And the big fish." Zhou Sheng stared at the fish detective picture, a little excited.

"These big fish are too scattered."

"Gather in the shallow layer and shout to Uncle Luo to speed up."

Chen Yuan let out a 'hmm' and picked up the microphone: "Fourth Uncle Luo, I received a reply." ”

"Roger."

"You speed up, too, this school of fish is too scattered, there are tuna underneath the school, but they are all very scattered." Chen Yuandao.

"Okay."

The Luo Lao 4 has been cruising, but his cruising is a little more than 13 knots, which is not much slower than the Xinhai with full horsepower. At full power, it can run seventeen or eighteen knots.

After Luo Laosi accelerated, he arrived before the Xinhai.

"We're here to help Master get off the net. Fourth Uncle Luo, can you handle it yourself? Chen Yuan took the walkie-talkie.

"No problem, I'll put the assault boat down and I'll be able to complete the net."

There is a skill in putting fishing nets, if there is no big boat to assist, when putting the purse seine net, you must consider the wind direction, the current of the water, the use of the purse seine to bring the resistance of the fishing net, with the strength of the fishing boat itself to drag the fishing net down, to complete the encirclement.

"After the master comes, you will divide the work and go to the net at the same time." Chen Yuandao.

"Okay." Luo Laosi looked at the fish scout picture in the captain's room: "The big fish are too scattered. My purse seine is only 130 meters deep and 1,100 meters long, so I guess it can only enclose a large group of fish. ”

"Try to surround the two groups."

The tuna here is estimated to be a small group, mostly in groups of three or five, or even large fish of a single individual.

The largest group, as you just saw, has only 7.

However, Lin Xinhai's fence is large, and there is an area of several hundred acres in a circle.

If you fence it up, you should be able to get more than two dozen tuna.

Luo Laosi saw that Lin Xinhai hadn't come over yet, and complained on the walkie-talkie: "You hurry up, it's really ...... Luckily, there are no other fishing boats here, otherwise you wouldn't even be able to eat in time. ”

"You're just eating." Lin Xinhai sat in the captain's room, staring at the console and was also very anxious, the speed of this ship is really nothing to say.

I didn't think it was like that before.

Now follow Chen Yuan and them out to look for fish, every time Chen Yuan and they find fish, they have to wait for a long time.

"Hurry up." Luo Laosi has some extremes now.

There are no fishing boats in the near distance, but there are in the distance. The flying fish swims fast, and the trajectory of the flying fish happens to be the fishing boat in the distance......

Hearing Luo Laosi's strong urging, Lin Xinhai's mentality exploded a little: "Don't rush, it's the fastest." ”
