Sailing is very important. Although there are no modern large sailing ships and no modern navigation equipment at present, navigation classes are necessary when taking the A-class sailing captain's license. How to use simple tools to determine the correct course and the geographical location of the ship by observing the position of the constellations, the moon and the sun is also a must-have exam. If you fail the exam, you will fail. This is because you are afraid that once the equipment on the ship fails, the captain will catch it. At least you can know the correct direction and direction, and wait for someone to rescue you, so don't run farther and farther.

What can this thing do in the Song Dynasty? It can sail far away! As long as you can sail long, you are a talent! The long-distance trade in this era is very, very profitable, but the limitations are also very, very large. Only a small part of this limitation comes from pirates and weather, most of which are due to problems of power and routes. Many long-distance fleets can only use the monsoon to run once a year, and they have to have a fixed route. If you change a little, you will not dare to go because you don’t know how to go to this place. The secrets of each route are hidden in the hands of those big families who control the fleet.

If you can open up new routes and create sea ships that can sail against the wind and sail faster, then ocean trade is not a dream. As long as you can run more times and faster than others, then being a sea merchant is not a dream. At that time, it will still be popular and spicy, and when you arrive at the sea, it will be your own world. However, this thing is still a bit far away now. First of all, you have to have a ship. How to build this ship, whether anyone can build it, and how to build it, and you still have to plan slowly.

The only thing that can make you live a good life is fishing! What does the chan family rely on to live? Fishing! Their boats can only stroll along the shore near the coast, and they can't go far away, and the nets are also very simple, so the daily catch is very small. The rice I ate yesterday was exchanged for fish and natives on the shore. This was to entertain Hong Tao, a guest, and they specially prepared to take out the inventory. If they were usually only able to eat taro to satisfy their hunger, and even taro had to exchange fish and shrimp with natives on the shore. They would not be full if they only ate fish and shrimp.

Before dinner, Hong Tao saw the net at Bofu's house. It was a net with a diameter of more than four meters. This thing was only suitable for shallow water. After it was sprinkled, it was a large circle, and it was tied to the heavy iron blocks around the fishing net, making the net cover like a large cover. It happened that the fish in the middle of the cover was frightened and bumped back and forth, and the fins would hang on the net, and were pulled up by the fishing net.

This kind of fishing method is too primitive and backward. It depends entirely on confusion. If you keep casting nets and closing them, the chance of being concealed is not too high. If you catch up with the reefs under the water, you have to go into the water to pick them up, which is both laborious and inefficient. Hong Tao’s improvement methods are divided into three types, all of which are tailor-made after fully considering the current era and economic conditions.

The first method is a ground cage. This kind of fishing method has been used in later generations and is especially suitable for lazy people. What is a ground cage? It is to roll the fishing net into a cylinder, which is usually more than ten meters long, and use materials such as iron wire in the middle to keep the barrel in shape and not to be deflated. The two ends of the barrel are not sealed, and a funnel made of a fishing net is sewn. The large mouth of the funnel is rushed out and the small mouth is towards the inside of the mesh barrel. Several such funnels can be opened on the mesh barrel, which is the passage where the fish enters. Then tie the mesh barrel with heavy objects and sink it to the bottom of the sea. A strong rope is attached to a float as a marker.

How do you fish this thing? You don’t have to take the initiative to fish. You just need to row a boat and throw this long net barrel into the sea. You can throw as many as you want. The more you want, the better. Fish have a habit of looking for hidden objects to hide. If these net barrel fish don’t know what they are, they will turn around and see that they have an opening, and will get in.

However, fish have no memory, or their memory is very short, only a few seconds. After drilling in, they forget the location of the exit and only know how to drill in the net barrel. Those funnel-shaped imports are easy to enter and difficult to get out because the fins grow along the way and will not hang on the net when they walk in. It is very troublesome to get out of the small mouth. It happens that some small fish can drill out, and most of them are trapped in the net. Depending on the number of fish in this water area, a few hours, half a day, one day or a few days, rowing to pull the ground cage onto the boat, and the fish inside will belong to you. The float tied on the water is a marker for fishermen to discover the location of the ground cage.

Can it work? Hong Tao can guarantee that this is 100% effective. This is not his invention, but the essence summarized by the Chinese working people from generation to generation. Whether it is fresh water or sea water, it can be killed! If you want to catch big fish, you can enlarge the mesh, and if you want to catch small fish, you can shrink the mesh, which is very flexible. The most important thing is that this fishing method does not take any effort or waste time. If you throw the ground cage, you can do whatever you need. When you collect it, you will work together.

If the productivity level is high enough and with the help of mechanical equipment, this kind of ground cage can be improved and turned into a large ground cage called the Maze Array. That thing is amazing. For middle and upper-level fish, it cannot get out if it goes in. A Maze Array can catch tens of thousands of kilograms of fish at a time. Many waters in later generations are not allowed to use this kind of thing, and it has too much lethality.

The second method is a crab cage. Hong Tao asked Bofu and their answers to catch crabs. Hong Tao was helpless. They dived down and grabbed them with their hands! It was so hard. Even if they saw a crab, they could not catch them even if they drilled into the cracks of the reef. Hong Tao's method was very simple. Just like making a ground cage, just stop using fishing nets. Use bamboo to weave a cage the size of a fruit basket, leave a round hole at one end, then tie a funnel made of a fishing net, and then attach a heavy object. It's OK. When using it, hang a small pile of fish or other meat in this bamboo cage, tie the crab cages one by one with rope, and throw them into the sea while rowing, throw as much as you want. After a day and a half, row and fish it up.

If there are many crabs in this sea area, there will be one or two in each cage, not only crabs, but also octopus, lobsters, pilosula, pilosula, and some benthic fish may go in and eat meat, but they cannot find the exit and become prisoners.

The third method is to deal with big fish specifically, called roller hooks! What is roller hooks? It is probably a thick rope that is more than one meter long is tied to a thick rope every one or two meters. A palm-sized iron hook is tied to the head of the rope, and a small fish is hung on the hook. At the same time, tie the thick rope to a float every few meters, and then row the boat to the sea where big fish often appear. Tie the hooks as long as the rope is. Don’t leave after putting it, and row the boat a hundred meters and stare at it.
