The double-layer fishing net has a variety of textures, divided into different prices according to different materials, and although it is two kilometers long, it can be converted into different breeding areas, about ten hectares can be used as a breeding area, so that even if a section of the net breaks, it will not cause all the fish to escape.

"In fact, the quality of these nets is absolutely excellent, do you want to raise them by sea or by lake? If it's sea-raised, you have to pretend to be shark-proof nets, after all, no matter how good the quality of the nets is, they can't withstand the sharp teeth of those sea monsters, right? ”

Wang Bodao: "I am a lake raiser, have you heard of Hawea Lake?" It's farmed there. ”

Raymond looked at him in amazement and said, "Lake Hawea? Of course I know, Twin Lakes isn't it? I remember it was a private domain, and the owner of the lake belonged to a stubborn old nobleman, and you got the right to develop it from him? ”

Wang Bo spread his hands and said, "So to speak, it can also be said that now I am the master there." ”

Raymond gasped: "The sun doesn't set, it fell into your hands?" ”

Wang Bodao: "Now it's called Sunset Town, I'm trying to make it an excellent town, are you interested in taking a look?" ”

Raymond's face was suddenly full of envy, jealousy and hatred: "God, you must have been favored by God!" Did you get that vast land? Ha, I'm sure now, you're not kidding me, you can easily buy my store. Go ahead, pick up these fishing gears, and I'll be happy to send them to your town and visit Sunset Town. ”

The next step is to select fishing nets, mainly to select materials, which Bo Dad is very interested in, Wang Bo and his father began to discuss.

Fishing net is a very ancient tool, in ancient China most of the use of hemp rope to weave nets, and then gradually use cotton yarn to weave nets, but these are only suitable for fishing but not suitable for captive net fish, because cotton thread and hemp rope are not resistant to water soaking.

In modern times, during the Industrial Revolution, people recognized the development of petroleum and the extraction of polymers from it, which led to the beginning of purse seine culture in the strict sense.

Raymond can provide a variety of materials for fishing nets, such as nylon thread, polyester thread, polypropylene thread, polyethylene monofilament thread and so on.

"I suggest you get to know the polyethylene monofilament thread, which has very good strength and aging resistance, and it has excellent dewatering properties, so it doesn't matter if you soak it in water for a long time, because it is insulated from water." Raymond recommended.

After discussing with his father, Wang Bo decided to buy a fishing net of this material, and chose the material of the fishing net, and also had to choose the wire diameter.

The thickness of the net line directly determines the performance of the fishing net, of course, the thicker the better, but if it is too thick the net line, it will cause waste, because after a period of use, the fishing net must be completely replaced, otherwise there will be a wide range of damage, and it is useless to repair and repair alone.

Modern purse seine nets are woven in a combined way, according to scientific statistics on the degree of wear and tear of different parts, and then use different thicknesses of mesh wires to weave.

For example, the top part of the net of the current universal fishing net, the top of the net down to the surface of the water is rarely damaged, it is exposed to the air, only through the wind and sun, there is no fish, shrimp and waterfowl impact.

However, the distance from the surface of the water to the bottom of the water is 2.5 meters, because it is often hooked by tree branches and reeds, so it is relatively easy to damage.

The most susceptible to damage is within four to five meters of the lower layer of the net, where the nets are often hit by big fish, and the bottom stones, grass roots, and aquatic weeds will also collide and scrape the nets, which can easily lead to serious damage.

Therefore, according to this situation, the top part of the general fishing net, that is, above the water surface, will be woven with four or six strands of polyethylene monofilament thread, while the first underwater area will use eight or ten strands of polyethylene monofilament thread, and at the bottom will be used more than twelve strands of high-grade polyethylene monofilament thread.

As for the color of the fishing net, Wang Bo chose the red, yellow, orange and purple four color exchange, the fish in the water has a very wide field of vision, and the bright color of the fishing net will stimulate the fish at a long distance, so it is necessary to be as eye-catching as possible to make them vigilant to avoid colliding with them.

Choose a good fishing net, and then choose crab pots and shrimp pots, which have higher requirements for materials, Bo Daddy recommends him to use chrome-plated stainless steel cages, which can be soaked in water for one year without rust, three years without deformation, and five years without breaking.

If the fishing net is 12 meters high, it is 44 yuan per meter, and 2,000 meters can be discounted, and in the end it cost him 80,000 yuan, a shrimp pot is 400 yuan, 50 yuan is 20,000 yuan, a crab pot is 550 yuan, and 50 is close to 28,000 yuan.

In total, it cost him 128,000 yuan to buy fishing gear alone.

Fortunately, there is no need to pay for transportation, and the fishery has a trailer that can haul the nets and cages through, which can be disassembled on all sides and reassembled at the lake.

Crab pots and shrimp pots have to be raised with crab fry and shrimp fry before being put into the water, while fishing nets are not good and have to be put into the lake first.

For purse seine farming, building nets is the most troublesome, it is very simple to say, just let go of the nets, and then hang the stones on the lower layer of the nets, so that the stones sink and drag the nets down.

But in fact, it is very troublesome, someone must follow in the water all the time, in order to avoid the fishing nets entangled, but also to inform the water surface of the depth of the lake in time, otherwise the depth is different, the fishing nets are tilted, and it is easy to destroy the nets under the action of buoyancy.

In the summer, the water temperature is high, but now in this season, the water temperature is below 5 degrees Celsius, even if you wear a warm wetsuit, you can't be underwater for a long time.

Raymond is a good businessman, he found a business opportunity from this aspect, the thief smiled: "I can help you find a few good divers, you know, we don't have any specialties here, but there are many good divers, how about it, the commission is very cheap, how many do you need?" ”

Wang Bo smiled: "Thank you very much, but I don't need this, I believe my luck will not be bad, just put the fishing net down, it won't be damaged." ”

He has the heart of a lake and can control the entire lake, even if the fishing nets are entangled, he can operate it through the sand table, which is easier than manually solving it underwater.

Raymond cleverly wanted to recommend his friend, but Wang Bo refused to agree, and after buying these fishing nets and fishing gear, he called Cousins and asked him to drive over and pull them back.

The big truck rumbled back and forth, and finally stopped on the shore of the lake and began to unload.

You have to hire Maori, and now the people who are most satisfied with the town are the people of Aturu, there are so many odd jobs in the town, they can do a little work every once in a while, they can support themselves, and they can go to the bar to enjoy it, and it is not too pretty.

Before sinking the nets into the lake, Wang Bo had to do one more thing, and that was to conduct field investigations. (To be continued.) )
