MTL - A Day In a Japanese Fishing Village-Chapter 43 light fishing

   (Thanks to the readers of 'Juekou p' for the 600 starting point coins!)

   "Switch vision!" Minano Shuichi said silently in the system, and his vision suddenly switched from the scene to the sea.

   "Extend to the northwest!"

   As Minamino Shuichi meditated, his vision soon moved towards the sardines in the sea.

   The bottom of the sea is currently dark, but Minamino Shuichi's special vision has no effect at all, and it is no different from the daytime.

   "Is this a spectacular school of sardines? It's really crazy."

  I saw that Minamino Shuichi's vision appeared in a sea that was about tens of meters deep, and in front of him was a school of sardines. Sardines belong to the upper class of fish in the ocean, so the waters where they are located are not very deep, and they all like to follow the currents.

   Nearly 60,000 sardines play in the sea and eat plankton in the sea. They are fast and almost every fish moves in a very uniform way! They go, move, turn, sink, go forward. It looks like a unified action anyway. It's like the phalanx of those soldiers who were in formation in ancient times!

   They seem to have been rehearsed thousands of times, and they are very tacit. The huge shoal of fish was black and pressed, and it suddenly changed into a ribbon shape, suddenly into a spherical shape, and suddenly changed into a vortex shape. They are like an infinitely changing flame, like magic, magical and fast.

   Anyway, it was the first time Minano Shuichi saw such a shocking picture, and he couldn't close his mouth in shock. This kind of situation is not seen on the sea surface, you have to be in the bottom of the sea to see such a spectacular picture.

   "It's a bit like watching a sci-fi movie." Minano Shuichi exclaimed.

   "Switch vision." After looking at it, Shuichi Minano took back his vision, and he was about to prepare.

   Fishing for sardines is not the same as fishing for other fish. It is a little special. Another is that Shuichi Minano felt that he had caught fish a bit too abruptly several times. As soon as I asked Kimura old man to change his route, he found that the school of fish was too strange. If it sounds good, it means luck, and when you change direction, you will find a school of fish. If you say it badly, it is a bit weird.

   This kind of thing is okay a few times, after all, luck can’t be stopped by anyone. But it’s not good to be like this every time. Although it won’t be caught and sliced, no one will grab themselves to slice. But this will inevitably make others think more. This kind of thing can be avoided.

   "Tanimura Ueno, go and take out all the fishing lights I bought before, and install five lights on each side of the boat. In addition, let Xiaokimura prepare the same way." Minamino Shuichi found Tanimura Ueno and instructed him.

   "Boss, are we going to try this light fishing?" Tanimura Ueno asked.

   "Yes." Light fishing was seen by Shuichi Minami from a documentary in his previous life. It tells how to use lights to fish on the ocean by fishing boats. He did not know when the light fishing started to be invented. It is also unknown when mass adoption will begin. Anyway, he saw that the fishing boats around him didn't seem to be in use.

   Actually, Minamino Shuichi didn't know that in the 1950s, light fishing on the ocean was not used by people, but less used, so he didn't see it. It is estimated that it will be more and more widely used after entering the development period of pelagic fishing in a few years.

   "Okay, I'm going to ask someone to help with the installation." Tanimura Ueno hurriedly went to work.

  All animals have a tropism for some substances, and fish are no exception. Some fish have a tropism for light, so you can use this to fish. Light purse seine fishing is based on the characteristics of the phototaxis of the upper layer of fish, using lights to lure fish groups and round up.

  Totaxis means that organisms with free movement ability cause movement in response to external stimuli. When this movement has a certain direction, it is called tropism. Movement can be divided into positioning movement and non-positioning movement and non-directional movement.

   Simply put, the lights can attract some schools of fish!

  In the ocean, many fish in the upper layer of the sea are attracted by lights, and sardines are one of them.

   Soon, fishing lights were installed on both sides of the Junxi fishing boat. In fact, these are not regular fishing lights, but an enhanced version of high-power special lights. Nemuro Fishing Port does not sell professional fishing lights. So he didn't know where to sell it. As for Nemuro City, he has not visited. The main is in a hurry to go to sea, and there is no time to inquire.

   The voltage of lamps and lanterns bought by Shuichi Nanye is more than 200V, as for the wattage, of course, it is not as good as later generations. The lighting industry in the 1950s was still developing.

   The lighting range is estimated to be about 50 meters. The light is not very strong, the penetration ability under water is not deep, and the aperture is small. It's a lot different from the documentary that Hideo Minami watched.

   "The underwater penetrating power of the light is estimated to be about ten meters deep." Nanye Xiu took a look at the effect at this time and estimated. The working depth of professional fishing teams like later generations has basically reached about 20 meters to 30 meters, and some are even deeper. Of course, the price of lamps is also more expensive.

For example, after the development of light fishing in the previous life was relatively advanced, we were looking for sea areas with complex underwater landforms and large changes in reciprocating currents, such as underwater uplifted sea ridges, mountains, concave trenches, large differences in topography, large differences in water depth and edges of deep lines. waters. In these sea areas, due to the large changes in water depth, it is easy to form upwelling, impact plankton and small fish and shrimps to float up, forming a good fishing ground for fish, which is an ideal place to turn on the lights to lure fish.

   After finding such a place, use sonar to detect the fish school or use a fish searcher to search for the fish school, and then choose a place with a better fish school image to turn on the lights to attract. Then put a net to round up when the fish is denser.

   However, the sonar detection of fish is not yet mature, and the fish search instrument has not been invented. The scientific and technological product of the fish search instrument will not appear in this era. But Minano Shuichi doesn't need these, because his peculiar ability to locate fish is more powerful than the above two technologies!

   Another is that if the light is used for 1 to 1 hour and the fish is still not attracted, the location must be changed. However, it should be noted that sometimes fish swim at the edge of the lighted area, and the light intensity can be reduced for testing; if there are fish at the edge of the lighted area, due to the phototaxis, the fish will quickly swim to the light source, and the image will be displayed on the fish finder screen, you can continue to turn on the light to attract set.

   Don’t pay attention to these Minamino Shuichi, the current light fishing is just an auxiliary tool for him to catch sardines, and his use of light fishing can explain that he did not find the fish by luck. Another is to prove that he is really good, haha.

  Although the effect of this fake fishing light is not very good, but this is not important. The lighting range is too small, and the light does not penetrate deep enough into the sea to attract fish? These are just minor problems. When the time comes to drive the fishing boat to the top of the fish, Minami Shuichi is not afraid that the fish will not come.
