After dinner, the Lixia turned on the fish luring lights, hoping to see if they could attract fish.
But after several hours of driving, only a few fish gathered.
The Shengyuan is drifting on the sea.
The wind picked up at night and the fishing boat turned on the stabilizer, but it still shook violently.
However, Chen Yuan slept peacefully and woke up the next morning.
In the cabin, Yang Xun was sleeping on the bench, and He Fei was preparing breakfast on the back deck.
I was in a hurry this time and only brought a few cans of lard.
In the evening, Yang Xun, He Fei and the others were on the night shift. Last night, the Lixia turned on the fish luring lights, and only a few fish gathered.
Yang Xun and the others were bored at night, so they took their fishing rods and caught a few fish.
I cooked fish porridge in the morning.
"Is it cooked?" Chen Yuan walked over.
"immediately."
Chen Yuan went back to wash his face and brush his teeth and then came out. The fish porridge had been cooked.
He Fei also woke up and was holding the Dragon Gate Formation with Zhou Sheng.
After dinner, Chen Yuan went to the cab of the Lixia, looked at the ocean currents and meteorological data of Xisha and Nansha, then returned to the Shengyuan and set out to look for fish.
Chen Yuan and his crew's boat speed is just over 18 knots, in order to save fuel.
The Lixia can cruise at about 20 knots, but in order to save fuel, it usually only runs at 14 or 15 knots.
Not long after setting off, the Lixia was left behind by Chen Yuan and the others.
However, Chen Yuan and the others had to search everywhere. Until after three o'clock in the afternoon, the distance between the Lixia and the Shengyuan was not more than 10 nautical miles.
No seabirds were seen, and no floating fish were found.
The weather is very good today, and the sea is rippling.
Chen Yuan once again released the drone, the M300rtk drone, with a maximum flight time of 55 minutes.
However, every time Chen Yuan releases his drone, it can fly for about 40 minutes at most.
The maximum flight altitude is 7,000 meters, and the maximum flight speed is 23 meters per second.
This is almost the best-performing drone that Chen Yuan can buy on the market.
When the drone rose to an altitude of about 2,700 meters, the sensors carried on the drone received intensive signals.
"Stop the boat." Chen Yuan shouted.
After sailing for a day, Zhou Sheng was bored to the point of pain. When he went out to sea, he looked at the Shengyuan and found that he felt uncomfortable everywhere. He felt that it was too depressing in the cabin.
It was sunny now, and he was still controlling the fishing boat from the bridge outside the cabin. When he heard Chen Yuan's voice, Zhou Sheng quickly slowed down: "Is there any fish?"
Chen Yuan controlled the drone to lower its altitude. At 2,650 meters, the biological signal source became a little weaker. Then he controlled the drone to fly levelly to find the location of the signal source: "There are fish, and there are a lot of them. Inform the Lixia to come at full speed."
.”
Zhou Sheng quickly ran back to the cabin and contacted Lin Xinmin: "Uncle Xinmin, I received your reply."
"Received." Lin Xinmin heard Zhou Sheng's anxious tone: "What happened."
"We found a school of fish, a big school of fish. Your fishing boat is approaching us quickly."
Lin Xinmin waved his arms excitedly: "Okay, we'll come here at full speed. Are there any other fishing boats around you?"
"There is a small fishing boat, but they probably didn't find the fish. Come over quickly."
“Can you estimate the number of fish schools?”
"Chen Yuan said it was a larger school of fish. I guess it's okay. There are a lot of fish." Zhou Sheng came over and took a look at the monitor and said, "Densely packed biological signals."
Chen Yuan has found the location of the fish school, at the two o'clock direction, at least five kilometers away.
An old-fashioned trawler can be seen on the sea, located at eight or nine o'clock from them, several kilometers away.
In other words, the fishing boat was at least 10 kilometers away from the fish school. The fishing boat was not heading in the direction of the fish school, which meant that it was a group of ownerless fish.
"Sail the boat, go over and take a look." Chen Yuan looked up at the sky. With his eyesight, the drone was just a slightly larger black spot.
As for Zhou Sheng's eyesight, he could no longer see the drone.
Zhou Sheng pushed the throttle lever and turned the horsepower to maximum.
Chen Yuan controlled the drone to descend to an altitude of 1,000 meters, and the signal source disappeared... This shows that the fish school is still far away, estimated to be eight kilometers away.
There are flying remote sensing fish finders that look for fish, which is like cheating.
However, remote sensing fish detectors also have disadvantages. If you fly too high and receive too many biological signal sources, the picture signals will be very dense.
This is a deep water area, and there are relatively few scattered fish. Suddenly there are many signal sources on the screen, so you can judge that there are fish schools around.
The drone descended to a high speed of about 200 meters, and Chen Yuan locked the fish school: "A big fish school."
"How many can there be?"
"There's a lot of it. But I don't know what kind of fish it is... If it's sardines, it's a small profit."
“What if it’s tuna?”
"If it's tuna, you'll get rich." Chen Yuan also relaxed and laughed.
Tuna, it depends on what kind of tuna it is.
There are only a few kinds of big fish in Xisha and Zhongsha, including sardines, Spanish mackerel, bonito, and pomfret.
In terms of fish school size, unless it is a mixed fish school, the only fish that can be excluded is pomfret.
Pomfret also likes to gather in groups, but the scale is not large.
The spawning period of bonito is from March to August, and now in mid-October, it is unlikely that there will be a large number of bonito.
Judging from the intensity of the signal source, it is most likely to be sardines.
However, the gathering of sardines can easily attract birds, but no birds were seen here.
The rest is mackerel.
As for yellowfin tuna, according to the received signal source, the number of fish schools is too large, and it is impossible to catch yellowfin tuna.
"Don't think about it, it can't be tuna." Chen Yuan became excited: "I hope it is Spanish mackerel. If it is Spanish mackerel, the net size will be at least several hundred tons, or even thousands of tons."
If it is Spanish mackerel, you will make a fortune if you catch it.
The main reason why Chen Yuan was excited was because he didn't see a flock of birds. So there was a high probability that they were Spanish mackerel.
Although Spanish mackerel can also attract birds, the temptation to birds is not that great.
Or a mixed school of fish.
Small fish schools will attract big fish to feed on them, just like the squid schools discovered earlier attracted tuna.
"Are there thousands of tons of Spanish mackerel?" Zhou Sheng asked doubtfully.
"Don't be so clumsy." Chen Yuan looked at the monitor: "Finally found a big school of fish."
As they were about to reach the fish school, Chen Yuan asked Zhou Sheng to stop the boat, take out the drone, and then place the sensor carried by the drone on the bow of the fishing boat.
"Has the fish detector been turned on?" Chen Yuan put away the drone and asked.
"It's opened." Zhou Sheng said: "No big fish were found. Not even small fish..."
"It's still far away from the school of fish."
Zhou Sheng started the fishing boat again and drove over at full speed.
Arriving at the outskirts of the fish school, fish finally appeared on the fish detection screen. These fish were very small.
"Sardines?" Zhou Sheng said.
Chen Yuan waved his hands vigorously, venting his frustration: "I guess so, but why are there no birds coming to hunt for food?"
"I'm so happy."
"There are a lot of fish, but you can still make money."
Chen Yuan was also a little disappointed. How could it be a large sardine school without flying birds?
Chen Yuan's fishing boat is just outside the fish school. Entering the fish school will disturb the fish, so they can only observe from the outside.
This school of fish is very large, and I am afraid that entering the central area will disturb these fish.
"Are you sure what kind of fish it is?" Lin Xinhai's voice came from the radio.
"Probably sardines."
Lin Xinhai was a little disappointed: "Are there any other fish?"
"We haven't found anything yet. We only observed from the outside and didn't go deep inside. We were afraid of disturbing the fish by getting too close," Zhou Sheng said.
