Qin Shiou was not depressed when he found no solution. He had an idea, but it was a bit dangerous.
The biggest difference between sail jellyfish and marine fish and shrimp is that it has no brain, so they don't know when they are hungry or full and eat all their lives. This ensures their survival to the greatest extent, but also brings other problems. .
¡°For example, they cannot transmit information, and they have no way to adapt after encountering a crisis.
Qin Shiou wants to use Poseidon consciousness to spread consciousness on a large scale, so that fish, shrimps and crabs can gather in a sea area and conduct blind inspections of other sea areas.
Fishing nets are useless now, not because the sail jellyfish is powerful enough to escape immediately, but because the fishing nets have many restrictions to avoid catching fish and shrimps. These restrictions give the sail jellyfish a chance to escape.
If there are no fish, shrimps or crabs to get in the way, fishing for sail jellyfish will be much easier.
Qin Shiou was planning how to do this. The fishing ground is too large. Even if the four consciousnesses spread information at the same time, it would be difficult to cover such a large area of ??water.
At this time, Sanders came to him and said, "Boss, maybe I have a way to deal with these jellyfish."
Qin Shiou was startled, then overjoyed and asked, "What can we do?"
The old professor pointed to the waves in the sea and said: "You know, sail jellyfish have very strong senses and can detect the appearance of a storm five to six hours in advance. So how do they judge the appearance of a storm?"
Qin Shiou knows this. Storms do not form suddenly. They are the result of the aggregation of groups of airflows. When these airflows accelerate, they will violently rub against the seawater and produce infrasound waves of 8 to 13 Hz. Jellyfish judge by receiving infrasound waves. The direction and power of the storm.
Seeing Qin Shiou nodding, the old professor ignored the principle and directly said the countermeasures: "There are enough boats in the fishing ground, whether yachts or fishing boats. As long as we set similar sound waves to the sonar and sonic instrument, we can cause damage to the sail jellyfish." cheat."
"They have no eyes or brains, and they move by instinct. So we can use infrasound waves to drive them away, concentrate them in a sea area, and catch them all in one go?"
After hearing what Sanders said, Qin Shiou's eyes lit up. What a difficult problem it is. It's such a simple matter. Just use infrasound waves to drive them together and salvage them. You can even hold up the net when the time comes and let them fall into the trap directly.
"Good idea, Professor, you are really good! I'm going to find the fishermen to work. Anyway, our fishing ground has nothing else but a lot of boats." With that, Qin Shiou went to inform the fishermen.
Sanders grabbed him and said: "Don't worry, boss, there is still a problem, that is, what should we do with the salvaged jellyfish? It is currently estimated that there are at least five million of them!"
Jellyfish vary in size. The sail jellyfish is relatively small, with an umbrella diameter of eight to ten centimeters. However, because they are rich in water, they weigh quite a lot when alive. Besides, millions of jellyfish will take up a lot of space when gathered together. space? How to deal with it?
Qin Shiou scratched his head. Most jellyfish can be eaten by humans. Sail jellyfish can also be used as food, but unfortunately they are not delicacies. In China, some people used jellyfish skins to eat cold dishes. When he came to Canada, he didn't even see this way of eating. Pass.
This also means that at least these sail jellyfish cannot enter the ranks of Daqin seafood.
After thinking for a short time, Qin Shiou said: "Perhaps, we can dry it and grind it into powder and sprinkle it back to the fishing ground to provide nutrients for plankton. What do you think?"
Sanders nodded and said: "Although this is not a very good idea, it is indeed an idea. Jellyfish powder and jellyfish fragments can be used as nutrients for fishing grounds. But boss, have you ever thought about where we store them after we catch them?" "
The problem is still not solved, what is missing now is a storage place of suitable size.
Qin Shiou waved his hand, "We'll talk about this later. Let's find a way to catch these damn jellyfish first. If we continue to let them go, my fishery will collapse!"
The sail jellyfish has four ring-shaped stomachs. These guys have nothing to do but eat and eat. Maybe you are monitoring now and see that they do not eat small fish and shrimps, but this does not mean that they have closed their mouths: they cannot be seen by the human eye. Wherever they go, they are still eating plankton!
According to statistics, if a jellyfish stays in a cubic meter of seawater, 70% of the plankton in the water will be consumed by it in just one hour!
And these plankton are food for small bottom fish such as capelin, herring, and mackerel. If they lose food, it means that the cod will have no food, and the entire ecological chain of the fishery will be affected.
Having found a way, Qin Shiou shouted on the Radio Town channel and borrowed a sonic instrument. There are quite a few of these in Farewell Town, and people usually use them to stimulate Asian carp in Shenbao Lake for tourists to shoot fish.
After getting the sonic instrument, Shaq and Black Knife began to modify it, and then hung it on the ship like an outboard motor. Four deck boats, the Sea Fist, the Harvest, the Auerbach, and two open-headed boats, and even The Night Thor motorboat was also sent to the battlefield.
With great vigor, a night battle began.
In the villa, Winnie's grandparents didn't know what was going on. They looked like a war outside and turned on the iodine tungsten lamp to start the fishery. Someone kept yelling, and they suddenly became a little scared and asked: "Winnie, what's going on?"
Wei Ni said casually: "It's nothing, Qin is taking them to work."
Winnie's grandfather sighed: "It's not easy to do breeding. Look, Qin still has to be busy at this time. We only saw the side of Qin making money, but not the side of him suffering hardship. Winnie, you have to be right Qin is better."
The long-legged flight attendant nodded meekly, but secretly complained in her heart that she had known Qin Shiou for two years, and it was the first time she saw him working at night. In the past, he would come back to sleep and give birth to a child as soon as the sun went down.
At sea, the happiest family at this time was the leatherback turtle family. Turtles of all sizes ran out. The big turtle took the little turtles and taught them to hunt sail jellyfish.
From the southeastern corner of the fishery to the mouth of the river, leatherback turtles came in large numbers. Qin Shiou had been monitoring the situation of the sail jellyfish through his Poseidon consciousness. He was greatly surprised when he saw the leatherback turtles sweeping all the way.
I was so busy working just now that I forgot that there are natural enemies of jellyfish in the fishing ground - but by the way, are there so many leatherback turtles in the fishing ground?
He remembered that there were only more than 200 leatherback turtles in the fishery, but now it seems that there are more than 200 large turtles with a plate armor diameter of more than one meter, and there are five or six hundred half-large turtles. As for the palm-sized turtles, Little Turtle, you need at least a thousand to start!
If you sow melons, you will reap what you sow. Leatherback turtles were very successful in breeding in the fishery last year. These turtles were all hatched last year. There were more than ten or twenty turtle eggs in a nest. All the eggs hatched successfully. Of course, there are many. . (Remember the website address: www.hlnovel.com
