The giant grouper was hoisted onto the Lixia and frozen.

Chen Yuan and Zhou Sheng helped build the fish collector, and all the accessories of the fish collector together have more than 20 tons.

It was busy at noon, the sun was about to set, and the fish collector was built. A group of three pontoons, each with a long rope hanging from it, and the long rope has anchor claws...... Strings of oyster shells are also tied to the rope.

A total of three groups of pontoons, spaced about 100 meters apart, form a triangle.

Lin Xinhai's fishing boat arrived late, and shouted over the intercom, "Luo Laosi, why are you here?"

"My fishing boat is always nearby." Luo Laosi said, "Are you going to sink to the bottom?"

"Huh?"

"How big is your net?"

"1,700 meters long."

"It's so long...... Some of the net circles are engaged, can your two apprentices do it? Otherwise, with my net, my net is only 1,100 meters wide and 170 meters wide."

"It's okay, we'll go back after this net." Lin Xinhai smiled, "Don't worry."

"I have a miserable harvest here, can you ask your two apprentices to help me make a net and share one-fifth of their catch." Luo Laosi said.

"One fifth, you're pretty good."

"A quarter."

"One-third, I'll help you ask. If it's missing, don't talk about it."

The most important thing in purse seine operations is to find fish.

A modern purse seine fishing vessel has to take up 50 to 80 percent of the entire operation time to scout the fish.

Before the negative tropical high pressure, Luo Laosi's fishing boat was suspended, and now the harvest is miserable.

Now the sea has just opened, and after a long period of recuperation, there are now many fish.

But for several days, they have not found a large school of fish.

There are a lot of fish, but they are all small schools.

Sinking purse seine nets can gather schools of fish, and most of the fish that gather are schools of high-value fish. For example, sea bream, there are a lot of brown plum sea bream here, as well as red sea bream, snapper family, and so on.

I made a fish collector, and as long as I was lucky, I could attract octopus and a small amount of tuna.

Sinking purse seine nets are no strangers to old fishermen, and they are traditional purse seine nets in offshore areas. In the domestic waters, the offshore fishery is not to say that it is depleted, but the sea area suitable for sinking purse seine nets is now depleted. The sinking purse seine was also eliminated very early in China.

This method of operation is still used in some Southeast Asian countries.

Offshore, the place where the fish are hidden is hidden in the coral reef, and the bottom of the sea with many rocks is not suitable for sinking purse seine nets. Even if there were divers going down to assist, those places would be very difficult.

There are many fish in Nansha, and there are many places suitable for sinking purse seine nets, but divers are required to go down to assist in the operation.

Divers dive to a depth of more than 100 meters, or even more than 200 meters, and operate around fishing nets, not to mention the danger factor, but also require divers to participate in higher intensity of physical work. Such divers are hard to find......

Lin Xinhai opened his mouth to catch one-third of the fish.

Luo Laosi was silent for a while before he said, "Let's take a look at the catch of your net."

"By the way, we found a Rocket-Eater gathering area earlier, and there are still a lot of Rocket-Eaters there. It is conservatively estimated that there is no problem with three to five tons of nets." Lin Xinhai said, "Why don't you go over and try it."

"Three or five tons in one net?"

The current price of rockets can still be sold for 70,000 or 80,000 yuan a ton.

There are so many rockets, Lin Xinhai don't do it themselves? Luo Laosi was a little unconvinced.

"I really don't lie to you."

"There are so many, why don't you do it yourself?"

"I was going to do it, but I came to the tuna school last night." Lin Xinhai said depressedly: "The strength of my ship's bracket is too small, and most of the tuna ran away last night. If you're lucky, you might be able to catch tuna at night."

"Okay, thank you. Give me the coordinates, I'll go over and see now." Luo Laosi said excitedly.

"The coordinates are for you, tomorrow afternoon

Come and help." Lin Xinhai said.

"Okay."

Lin Xinhai smiled and gave the coordinates of You Yuqun to Luo Laosi.

You fish are an alternative for Lin Xinhai and them, if they find a good location for sinking the bottom purse seine net, then they will not catch You fish.

The fish collector has been arranged, and Chen Yuan drove the fishing boat to the side of the Xinhai, and hung down the iron cage, rope, and float...... and frozen Antarctic shrimp.

It's getting dark.

Lin Xinhai came to their fishing boat: "Have you explored this location, is it good to collect the net?"

"It's okay, there's a piece of gravel flat land of dozens of acres down there." Zhou Sheng said, "By the way, there is an ancient shipwreck down here."

Lin Xinhai was stunned for a moment: "Are you sure it's an ancient shipwreck?"

"Eight, nine, not far from ten." Chen Yuan said and took out a few pieces of ceramic shards picked up from the bottom of the sea and looked at Zhou Sheng.

Zhou Sheng's face twitched slightly, and he went back and took out the silver ingot: "There is also a silver ingot."

Silver ingots in ancient times were of average value.

If you take it out, it will be tens of thousands of dollars at most. Silver is not gold, and now gold is hundreds of dollars per gram, and the price of silver is a few dollars per gram.

If you really want to put yourself in it for this benefit, there is no need.

"Where can I report the discovery of an ancient shipwreck? Can I get a bonus?" Zhou Sheng said with a smile.

"There must be a bonus." Lin Xinhai said: "I don't know which department to report, just the Maritime Safety Bureau, and contact the Maritime Safety Bureau when we close the net."

Lin Xinhai doesn't care about the shipwreck on the bottom of the sea, it's illegal for that thing to be salvaged privately.

No matter how high the value of the shipwreck is, if you put yourself in it, you can't make a mistake. It's not that they don't have the ability to make a lot of money by legal means.

Lin Xinhai came to the fishing boat and helped put the bait cage.

This time, I came out and brought more than 2,000 catties of Antarctic shrimp, some of which I used before, and it is estimated that there are still 2,000 catties left.

Some Antarctic shrimp are packed inside an iron cage and sink to the bottom of the sea. There are also pontoons attached to fish collectors to lure surface fish.

These are Antarctic shrimp used for feed, just a shrimp head, and shrimp shells. It's only a few dollars and 1 catty.

It's past nine o'clock in the evening. Sending Lin Xinhai back, Chen Yuan fixed the fishing boat next to one of the pontoons, and the Lixia drove to the middle of the three groups of pontoons and turned on the fish trapping light.

At night, Zhou Sheng made a potato beef stew, and he has to work tomorrow, so he will have a good meal in the evening.

This night, the fishing boat was fixed on the pontoon, and Chen Yuan and Zhou Sheng both slept soundly.

When he woke up early the next morning, Chen Yuan turned on the fish detective, and the picture was densely packed with fish.

"Master, how many fish do you see over there?" Chen Yuan took out the walkie-talkie and contacted Lin Xinhai.

"Many." Lin Xinhai said with a smile, "It's still a little short of exploding. Have you seen any big fish over there?"

"No, it's mostly small fish."

"Wait, wait for the tide, wait for the big fish to come." Hayashi Shinkaido.

"Prepare yourself to go to the net." Chen Yuan said.

"I'm preparing."

As soon as it was dawn, the Lixia left the center of the pontoon and joined the Shinkai on the periphery
