Fishing vessels, freight business, all under the management of Chen Erlei, so he knows this best, before this, the domestic use of drones, for fish fishing is still a blank, but in foreign fishing boats have used drones for precision fishing, the results are obvious.

Now, the drone has been tried on Mo Ye's ship, even so, Mo Ye is not satisfied with the performance of the current drone, this time, in fact, it is also a sea trial.

Although he tried it a few times, Mo Ye hadn't seen it with his own eyes, so he naturally didn't know if it was really easy to use.

Of course, you don't need to see it with your own eyes, Mo Ye also knows that it must be flawed, so Mo Ye has also begun the development of a new generation of "fish hunting drones".

The new model Mo Ye plans to expand directly to a diameter of 3 meters, with a time of more than 3 hours in the air, and a maximum flight distance of more than 100 kilometers.

This model can be developed and put into trial at the end of the year at the earliest, when a large number of distant-water fishing vessels equipped with UAVs "cruise" the ocean, the picture will become a reality.

And the reaction to Mo Ye is that it can make it easier for him to see the fish under the water, just like now, the drone has fed back the detailed information.

"I didn't expect there to be so many large prawns in Bohai Bay!" The super biodetector connected to the drone and accepted the data, plus the data from nearby scans, which made Mo Ye a little surprised.

"There are very few now, and there are almost no big schools of fish to be seen!" Lin Yumin shook his head and said.

Lin Yumin clearly remembers the scene of fishing at sea with his parents in the 90s of the last century.

"At that time, I was not idle all year round, catching clams and crabs, catching crabs and catching pomfret and catching pomfret and mackerel and jellyfish after catching pomfret and jellyfish...... When you look at the sea, there are groups of fish, and you can pull up thousands of pounds of palm-sized prawns, yellow catfish and mackerel more than one meter long, and now, there is no stock in this familiar sea. As he spoke, Lin Yumin sighed.

"Look, this isn't a prawn?" Chen Erlei said with a smile.

Lin Yumin laughed and said: "This is just prawns, but more are skin shrimp, these are crabs!" ”

Looking at the data on the tablet, Lin Yumin said: "In the 80s and 90s of the last century, wild shrimp more than two fingers long could be caught in the Bohai Sea, but this kind of shrimp has long disappeared. ”

Mo Xie knew that what Lin Yumin said was true, and now despite the implementation of the fishing moratorium system, it is still difficult to see a bumper harvest of fisheries in spring and autumn, let alone the fishing songs of the four seasons!

At present, there are only a very few species such as skin shrimp and crab with strong survivability, and the traditional fishery specialties such as hairtail, snake, red sea bream, wild flounder, and wild puffer fish are almost extinct. ”

For what Lin Yumin said, Mo Xie is of course very clear that the fishery resources of the Bohai Sea have been reduced from 95 species in the past to 75 species at present, among which the fishery resources with important economic value have been reduced from 70 species in the past to about 10 species at present.

Lin Yumin shook his head and said: "In the past 20 years, the well-known economic varieties of the Bohai Sea, such as pike crab, yellow croaker, squid, silver pomfret, and hairtail fish, as well as low-value resources such as hairy shrimp and cockles, have been depleted one after another, and the main economic varieties have been unable to form fish floods for a long time. ”

Fish flood refers to the period when certain fish are concentrated in a certain water, which is suitable for fishing operations, and now although the Bohai Sea is large, there are not many sea areas suitable for fishing operations.

The Pacific Ocean is very large and abundant, and there are abundant fish and shrimp, but it is difficult for fish and shrimp in the Pacific Ocean to swim to the shores of China.

In order to "intercept" more fish in front of others, fishermen can only desperately move away from the inland sea to the east, and finally go fishing near the border waters of China, Japan and South Korea.

Now, Mo Ye and the others have just left the port, and they can see the shrimp, which is not easy.

In recent years, in order to alleviate the pressure on fishery resources in the Bohai Sea, since 2005, several large surrounding provinces have organized the release of shrimp and crabs every year.

Since 2007, the system of fishing moratorium has been implemented, and it is only now that it is gradually showing results.

"Before the release and the suspension of fishing, the annual output of the Bohai Sea shrimp was only a few tons, and now the annual output of the shrimp can reach the level of several thousand tons, but in recent years, the effect of the release has become less obvious, although the release is more and more, but the output of shrimp and crabs has not increased accordingly." Lin Yumin said.

"Why is that? Isn't it true that the more you put it, the more you will reap? Chu Tianyi asked.

The release is not something that can be seen in a short period of time, but now the Bohai Sea area has also had some effect, otherwise they would not be able to see the shrimp.

"This is really not necessarily, the release needs to be carried out scientifically and rationally in combination with marine biological investigation and research, not the more the better, you two come over to help." At this time, Mo Ye spoke.

At this time, what Mo Xie wanted to start was another advanced equipment on the ship-sea motorcycle, which was originally an ordinary thing, but it was improved a lot by Mo Ye, and it became advanced, and of course, the price also soared.

"What is this for?" Deng Chuge touched his chin and asked.

"Diving motorcycle!" Mo Xie said with a smile.

If you don't go to sea, you don't know the size of the ocean, you don't go out, you can't see the magic of this world, and when you come to the sea, Deng Chuge and they can be regarded as having increased their knowledge, and then they know that there are motorcycles that can dive in this world.

"You wait, I'll get some Bohai pairs for you to taste!" Mo Xie smiled, and controlled the motorcycle to row under the fishing boat, where a floating dock was prepared, which was specially prepared for small boats such as speedboats and motorboats.

"You just went into the sea like that?" Seeing Mo Ye dressed in casual clothes, Chu Tianyi said strangely.

"Haha, forgot to change clothes!" Mo Xie hurriedly changed into a diving suit and brought an oxygen tank, of course, he hadn't forgotten to take a few nets.

There are really not many shrimp schools in this sea area, and as the fishing boats speed up, there are fewer and fewer shrimp schools found now, and if it is later, it will not be easy for him to chase after he goes to sea.

The diving motorcycle is an internal electric power, and the noise is very low after starting, but the power is not small, so the speed under the water is very fast, but in this way, no matter how Mo Ye modifies, the range of this diving motorcycle is not large, and at this time, this improved model will run out of power after driving a maximum of 100 kilometers.

Of course, Mo Xie also has a solution, that is, to add a few more motorcycles, so that he can always race on the ocean by rotating them.

In fact, the water in the Bohai Sea is not deep, and there are not many waters more than ten meters deep, so even if Mo Xie does not enter the water, the super biological detector can catch all the fish and shrimp within the range it passes.

However, it is difficult to explain what is done, there is no way, Mo Ye can only let the motorcycle dive.

Of course, if it was in the open sea, Mo Ye would not need to do this, he could have fished freely, but here, he couldn't, because the little aquatic products here were all the fruits of other people's release.

The state releases 1.5 billion shrimp seedlings into Bohai Bay every year, and as of the end of December every year, fishermen have recaptured more than 1,000 tons of Chinese shrimp, and the refishing rate has only reached 2.24%, but even so, the total output value has reached 240 million yuan, and the input-output ratio has reached 1:11.21.

While increasing the economic income of fishermen, it also protects the biological resources of the Bohai Sea, and has achieved a win-win situation of economic and ecological benefits, which is already very good.

This time in the water, Mo Xie wanted to prepare some fish, shrimp and crabs, after all, he was going home, how could he bring more seafood, he was going to vomit when he ate this thing, but in his hometown, it was still a good thing.

It turned out that the ones he caught, after half a year of consumption, have been almost processed by him, and now he catches some fresh goods, just for his parents to taste.

Of course, this is also Mo Ye's filial piety, after all, now that the super biological detector space can store living creatures, naturally he can't let his parents eat dead seafood.

Chinese shrimp is a special product of Bohai Bay, rich in nutrition, delicious and soft meat, because of its special preciousness and relatively small quantity, for this year, the autumn and winter catch of Chinese shrimp is rarely directly marketed, but is bought and frozen by some large aquatic enterprises, and then sold during the Spring Festival.

Therefore, Mo Xie personally went into the water, just to get some of the freshest delicacies, of course, he also wanted to catch some big prawns, the kind of prawns that were born back then, and he didn't see them in his eyes.

As soon as he entered the water, Mo Ye stared at several big ones, which were really big, each of them stretched out in the seawater, and their size reached thirty centimeters.

This is definitely a veritable "Bohai pair", such a prawn, the whole body is composed of more than 20 segments, the general body can reach more than 20 centimeters, more than 30 centimeters of large size, even the local fishermen are not easy to eat.

In recent years, due to seawater pollution and overfishing, wild Chinese shrimp is almost extinct, in 2006 the city carried out the breeding and release, up to now, has accumulated more than 5 billion Chinese shrimp and other seeds, before gradually forming a shrimp flood.

It is also because of the formation of shrimp floods that Mo Xie can find the shrimp school so quickly, which is the role of unmanned helicopters.

The unmanned helicopter searched for fish and shrimp on a large scale, and when the search was found, it was the turn of the diving motorcycle and the super biological detector to show their skills.

With such a targeted entry into the sea, Mo Ye's harvest will naturally not be less, just ten minutes, Mo Ye caught thousands of kilograms, which is a ton.

Of course, compared to other fish stocks, this receipt is nothing at all, but with Bohai shrimp, this kind of production is quite a lot.

You must know that after the start of fishing this year, the maximum daily output of a single ship will only reach 300 kilograms, which has not been done for many years.

A boat, only 300 kilograms a day, is only one-third of Mo Ye's, and this is because of Mo Ye's picking, otherwise, Mo Ye's harvest will be higher.
