"Okay, let's go fishing for lobster this afternoon and eat lobster and abalone in the evening. Now let's get ready. Let's take a look at the professional fishing nets Rong Xia brought back. △↗," Han Jianguo said.
"It's not a fishing net, it's a shrimp net. It was bought from abroad and is specially used to catch lobsters," Han Rongxia said.
"No matter what kind of net it is, as long as it works, let's go, let's go with the whole family. We couldn't catch a few big lobsters like that in the village. If this shrimp net is really useful, then it will save trouble in the future." Han Jianguo was happy.
The way.
"It would be great if there were shark fins. When I grew up, I heard people talk about abalone and shark fins. Now I want to eat abalone, but I haven't seen shark fins yet!" Han Rongxia said as he stood up.
"Are you really greedy? You don't know that sharks are protected animals? Without greed, there would be no killing. The massive decrease in the number of sharks is caused by foodies like you." Han Rongguang looked at Han Rongxia with contempt and said.
"Third brother, are you looking for a fight? There are not enough sharks for brother to do experiments? I am reminding brother to be less greedy and not to hunt sharks in large numbers in the name of scientific research." Han Rongxia looked at Han Rongxia.
Rongguang, with a righteous expression on his face.
Han Peacock couldn't laugh or cry: "Most of my sharks are raised by myself, right? It's not easy to eat shark fins. I will take you to hunt sharks in the evening."
"Shark hunting? This is not easy. Shrimp hunting is so troublesome. Don't you need to be well prepared for shark hunting?" Liu Xu frowned.
"Don't worry, you won't be in danger as long as I'm here." Han Peacock said with a smile.
"It's up to you, as long as you know what's going on," Liu Xu said.
"Haha, it seems that I ate shark's fin at night, so I will exercise hard this afternoon and try to eat more at night. I haven't eaten shark fin once!" Han Rongxia said with a smile.
"You'd better be prepared! I heard that it's not easy for professional shrimpers on large fishing boats to catch lobsters. Do you think your so-called shrimp net can work?" Han Ronghua said at this time.
Han Rongxia said: "Of course, you just watch."
"Don't be too blunt, but I know that shrimps are not easy to catch. Most people don't know how to catch shrimps even if they go fishing." Han Peacock said.
Fishing for shrimp is very troublesome, otherwise anyone with a discerning eye would know that a pound of cod can be sold for more than ten dollars in the international market, and a pound of vannamei shrimp, the largest one, only costs about seven or eight dollars.
Shrimp requires less feed, has a higher feed conversion rate, and is more expensive. Why are there fewer and fewer shrimp farmers?
It’s just that once you plant the seedlings, you can’t get them back!
The shrimps will run away if you cast a net to lure the shrimps, but the shrimps will not come up if they are smart or don't want to eat them. Nowadays, there are various shrimp lures sold online, but the effect is not very good.
Before the development of shrimp fishing technology, shrimp fishing even required people to dive into the bottom of the water, push away the gravel with their hands, and then catch them directly...
This is much more difficult than picking clams and geoducks, because the latter two basically cannot move, while shrimps are more flexible than ordinary people underwater.
Looking at a pile of things, Han Peacock was thinking about how to use this thing, and the flatbed truck was already pushing it to the dock.
The pier in the village is very small, and the boats are even smaller. They are just flat-bottomed boats that are four meters long and a little more than one meter wide.
The shrimp net must be installed on a powerful fishing boat to work. This thing has great resistance and is difficult for a small boat to move. But with just one look, Han Peacock knew that Han Rongxia was not messing around.
Han Kongque followed him with a calm face. Although his expression was not revealed, the three Liuxu girls knew that he was in high spirits at the moment.
When we arrived at the dock, Han Rongxia had already asked someone to bring the boat over.
"I had someone refit this boat in advance. It has high horsepower and is enough to drive this shrimp net." Han Rongxia said.
"Okay, what to do next?" People like Han Kongque couldn't handle this "net", so they had to ask Han Rongxia.
"I've prepared it in advance. I just need to assemble it a little. When the time comes, load it on the boat and just launch it directly into the net." Han Rongxia waved his hand, and several crew members came to help. Two people worked together to put the things on the ground.
Soon, something like a football goal appeared!
This thing looks like a big forklift, and it’s the kind with a cover on it!
At the front of the shovel, poke out a probe half a meter apart like this. The probe is slightly rolled up, so even when it is started, it will not catch anything and cause it to be unable to be pulled...
The most amazing thing is that there are wheels under the shovel, presumably to prevent wear and tear when mopping the floor.
But this can’t catch the shrimps on the bottom of the sea at all!
"This thing can only be used in relatively flat fishing grounds. If there are shrimps, you can definitely catch them. If you put them in deep sea fishing, they will be easily damaged." Han Rongxia said a little excitedly.
There was a black box next to Han Rongxia. She pressed hard and opened it!
"I thought it was something, but it turned out to be an electric fish device!" Han Peacock was looking at it carefully, and when he saw it was an electric box, he jumped up.
Everyone was staring at Han Rongxia, mysteriously, you actually took out this thing?
"Using electricity is extermination fishing. Is it illegal? Even if it is not illegal, do you still want to destroy your own farm?" Han Peacock asked after taking a look at Han Rongxia.
"No, I can't kill the fish with electricity." Han Rongxia said proudly.
Han Peacock's eyes lit up and he understood immediately!
"The fish won't be electrocuted? Then you are too weak. We used to electrocute fish, and even people could be electrocuted frequently." Han Rongguang curled his lips and said.
"..."
"..."
"..."
After laughing for a while, Han Rongxia explained the principle of this device to everyone. When she told everyone about the distance, everyone couldn't help but marvel!
This is a shrimp net specially designed for ocean shrimp fishing. It is the best for catching various shrimps in the ocean.
As long as there is movement, the first reaction of shrimp is to hide in the sand. This is a very timid creature, so ordinary trawl nets do not work well in ocean fisheries to catch shrimps. The shrimps will bury themselves with just a few brushes.
.
Using trusses is time-consuming, labor-intensive and expensive, and the effect may not be as good.
The "probe" of this net will emit a weak current. This current will not kill anything, but it will make the shrimp feel that there is something in the damn sand...
Then he jumped out and was caught in the trawl net!
Through the mesh of the trawl net, the size of the captured shrimp can be controlled. After catching, it is enough to do a little size classification, thus avoiding "one pot".
Cold-water shrimps such as Arctic sweet shrimps are 10 grams each and no one eats them here. They are all made into dried shrimps and sold for takeout. Sometimes they are strictly controlled and even refuse to trade shrimps of this size, but 45 grams each
All kinds of cold water shrimps sell for nearly ten dollars a pound.
Global cold-water shrimp production was in short supply last year, and prices may even increase this year!
About 40 to 45 grams of shrimp are the most cost-effective, but shrimp of this size are already very smart...
When the last box was opened, it was a computer. According to Han Rongxia, as long as it was connected to this computer, she could accurately control the current intensity at the tip. As long as the tool was not damaged, this shrimp net could even be used at a depth of 300 meters!
There are some things that require special attention. One is the structure of the network, and the other is the computer.
Everyone was stunned for a moment, and Han Ronghua strongly suggested trying it.
Now Han Peacock's ocean-going fleet's harvest is all handled by Han Ronghua. If this kind of shrimp net is really that good, there will definitely be a dramatic increase in shrimp in the fleet in the future, so she will have to deal with it accordingly.
The factory makes adjustments.
It is easy to eat shrimp but difficult to catch shrimp. This saying is that shrimp is the easiest to eat among seafood. There is no special method to cook it. You can eat it one bite at a time, but catching...
The general method of fishing for shrimp offshore is to drag shrimp with a beam.
Several people hold a steel pipe of at least 20 meters to set up the nets, and then use nylon ropes to slowly surround several nets. It is more difficult to open and close the nets, and the workmanship is very intensive.
The most important thing is that the cost is extremely high. In the end, a bunch of small shrimps are caught, which reduces the profits of each net, and may even lead to the extinction of fishing. For example, it was difficult to find shrimps during the fishing moratorium in Cambodia last year.
China's management is so strict. At least a thousand fishing boats are lined up every time, which causes great damage to the sea.
Han Ronghua didn't believe that just this small device, with a little modification, could optimize the shrimp fishing effect several times, so he took advantage of his free time to try it out now.
The method of catching shrimp is trawling, as long as the speed is faster than the shrimp, some fast fishing boats can even catch tuna and sailfish with trawling.
Everyone installed this device on the ship. This was a test product brought by Han Rongxia. The size was a bit inappropriate, but the problem was not major.
This thing is easy to assemble and unload, and the current intensity is easy to control.
The fishing boat must follow the "back-shaped" structure and circle around the largest dam in the village. Not to mention 100%, at least 95% of shrimps of the right size can be caught. According to Han Rongxia, this boat is a bit small, two hundred
Ton-sized fishing boats are more flexible in this regard.
After walking less than a hundred meters, Han Rongxia asked the boat to stop for inspection.
"Two hundred pounds! They are all big!" Han Ronghua flipped through the shrimp net, his face full of surprise.
If a fishing boat with a displacement of 200 tons is used to collect shrimps, the water surface can be cleared in about ten minutes. In this way, no matter how many shrimps are raised, the manpower will be enough to collect them!
Of course, this is not a small fight in the village, but in the waters of Peacock Island, or even extended to the entire Peacock Kingdom.
Korean peacocks now occupy more waters than even the two superpowers China and the United States. In such a large area of water, there are too many places suitable for breeding marine shrimps.
It's just that it used to be difficult to harvest shrimps, and the Peacock Islands lacked manpower from the beginning. Now that there are such professional shrimp nets, the situation will be different in the future.
Several people on the boat were very excited. In the future, diving for shrimps and dragging shrimps with a boom will become a thing of the past.
"Rong Xia, your invention is no small matter." Han Peacock said with a smile.
Han Ronghua said: "I'm afraid Rongxia made it specifically for the two of us to see."
"Otherwise, with her cleanliness, she would come and help us catch shrimps?" Han Kongque said. (To be continued.)
