A Day In a Japanese Fishing Village

   (Thanks for the 2000 starting point coins of Pinellia Sadness!)

   Minano Shuichi guessed that when the system was upgraded to level 5, he believed that the system would not give him the ability to upgrade the fishing grounds. It should give him a new ability upgrade! This is all a guess in his own heart. It is the system that has the final say on what new abilities to upgrade when the time comes.

   After washing up and having breakfast, Shuichi Minano's fishing fleet arrived in the sea to the southwest an hour later.

  The North Pacific Ocean is located between Asia and North America, between north of the equator and near the poles. The Bering Strait is connected to the Arctic Ocean in the north, and the sea surface temperature gradually decreases with the increase of latitude.

   In addition to being a very important fishing ground, it is also a major shipping route in the world. Many cargo warehouse cruise ships pass through the North Pacific Ocean!

   When Minamino Shuichi came here, he found that the fish that he had discovered before had already gone by the time he arrived. However, at this time, the system reminded again!

   "Ding dong... A bonito school was found 9 nautical miles from the host in the due north direction. The fish school's coordinates are 155.8 longitude and 41.3 latitude. The number of fish schools is 4027!"

   "More than 4,000 tuna!" Minami Xiuyi gasped, my God, more than 4,000. This belongs to the super large school of tuna.

   After getting this explosive reminder, Shuichi Minano immediately drove the fishing boat towards the position of the fish school due north. At the same time, he also switched his vision to see what this group of tuna was doing!

   Soon after switching his vision, Hideo Minano entered the sea, and it didn't take long for him to find the location of the tuna school. I saw the depth of the sea here is about one thousand meters deep.

   A group of huge bonito is gathering ahead!

   "Hey...what is this! Tuna school tornado?" Minami Shuo was stunned by this sight! It was the first time he saw such a scene. I saw more than 4,000 bonito fish slowly swimming in circles in the seawater ahead. They slowly rolled around, forming a fish tornado composed of fish!

  This tornado is seven or eight meters in diameter and dozens of meters long. It's like a tornado on land, only this one is in the water, or is it made up of these tuna!

   "It's so spectacular!" Minano Xiuyi's eyes widened in disbelief. It was the first time he saw such a shocking picture.

   "Isn't the tuna swimming very fast? Why is it so slow now." Minami Shuuichi said incredulously.

   The tuna tornado in front of me slowly swept through the water, and the tornado composed of more than 4,000 fish slowly drifted along with the ocean current. Their speed is very slow, and it feels like they are foraging and migrating, and they seem to gather together to exchange information. But what puzzled Minano Shuichi was that they were too slow.

   shook his head, Minamino Shuichi couldn't understand, but it would be great if this shocking picture of the fish tornado could be photographed, it was really shocking.

   Actually, Minamino Shuichi didn't know that the sea area where tuna spawned and migrated was affected by various natural factors. During the spawning period of tuna in suitable waters, their migration speed is very slow unless the sea conditions change abruptly.

  Many masters of tuna fishing are based on frequent observation, understanding and mastery of the direction and speed of the ocean current, which is conducive to tracking and chasing the fish group and increasing the catch.

   According to the production practice over the years, many experts in later generations have found that the tuna that swarms for bait have the laws and habits of drifting downstream and chasing bait against the current.

The direction of the current is stable and the flow rate is stable, that is, when the flow rate is 0.5~1.5 knots, the central position of the tuna swarm feeding is not much changed, and the fish generally drift downstream about 16,000 meters every day; the flow direction is stable, and the flow rate is 1.5~2.0 knots , it is more difficult to track the fishing group. There are many planktons and small fish in the sea currents with large changes or at the confluence of sea currents, which are the fishing grounds for tuna bait. Current direction and velocity greatly affect tuna longline operations.

The migration of   tuna can be divided into two forms: one is that in the same ocean current system, the local migration mostly belongs to the same ecological migration, but there are also ecologically different groups. In this case, its migration is dominated by the ebb and flow of ocean currents. The second is the transitional migration between different ocean current systems, which is caused by the needs of fish ecological changes, and then prompts the fish to start to migrate automatically and actively.

   Now, what Minano Shuichi encounters is the tuna rafting downstream, so their speed is very slow, and they only travel about 16,000 meters in a day. If they're counter-current bait, they can swim terribly fast! This is one of the reasons why tuna appears from one ocean to another within a year.

  Counter-current bait fishing. Many fishing masters in later generations used this feature to fish tuna with trolling and trolling! Because this kind of trolling is a type of retrograde bait. As long as those tuna find it, they will definitely catch up and hunt for food!

  Don't underestimate the currents, if you can identify the currents, it will be very useful for you to hunt for fish in the ocean! Just like sardines are one of the fish that drift with the ocean currents. They also like to drift with currents in shallow waters because they are pelagics.

   For Minami Shuuichi, these kinds of experiences are not very helpful to him. He has system prompts to find them, and he can just kill them directly.

   "Now that we encounter such slow-moving tuna schools, trawling will be even easier!" Minano Shuichi laughed.

  When the fishing boat approached, Minami Hideyoshi could see at a glance that dozens of meters ahead, there were fish schools and some tuna spinning at the top of the tornado.

   He would like to ask if you are not dizzy walking around like this?

   Just now, he observed that there are many small fish in the place where this group of bonito fish is, and they are lazily migrating and eating lazily. In fact, this is also a kind of transgender rest.

  Tuna can't stop for a lifetime, and as soon as it stops, it will die, it will suffocate to death! It has some similarities with sharks. Sharks can choke if they stop swimming.

   "Draw down the net!" Hide Minami said to Ishida Yu who was beside him.

   "Boss, have you found a school of fish?" Ishida Xiong squinted and dozed next to him.

   "Nonsense, hurry up! The fish is right there." Minano Shuichi pointed with a finger.

   "Boss, how did you find out?"

   "Hehe, of course it's based on experience, have you seen the ocean currents here..." Minano Shuichi started talking nonsense with his eyes open again, but this time he was really right.

  When the trawling nets were put down and surrounded by the tuna school, the group of more than 4,000 bonito fish were still drifting slowly along with the slow current.

   The trawl nets, which are tens of meters wide and tens of meters high, come directly toward the bonito school.

   The fishing boats are fast, and so are the trawls!

  The next second, the trawl port came to the front of the fish school. At this time, the huge trawling net bit into the fish like a swallowing giant beast.

The part of the bonito that started    was swallowed without a response. The bonito fish in the back immediately realized that something was wrong and started running around.

   This huge fish tornado was scattered all of a sudden.

  Minano Shuichi switched his vision and stared at the movement of the fish, generally driving a fishing boat to chase.

   The originally slow bonito, under the pursuit of the trawl net, accelerated in vain and kept fleeing.

   "Hmph, don't try to escape!" Hideo Minami's Falcon's speed has been increased to the maximum, and the fishing boats dashed in from left and right, closely following the large group of bonito fish.

   "Whoosh whoosh!"

  The speed of the tuna in the sea water is so fast that it scurries around like bullets. However, there was absolutely no chance of escape under the huge trawling net. Some of the bonito also ran back stupidly, only to crash into the fishing net and wait to die.

   Minano Shuuichi's pursuit lasted for more than half an hour before it came to an end.

   He only caught about 3,000 of the more than 4,000 bonito, and about 1,000 escaped. There was nothing to do about the part of Shuichi Minano who escaped. Who called tuna speed is too fast. This time he caught about 3,000 fish and was very satisfied.

  The next step is to start the net!

  3,000 bonitos were hoisted out of the water and turned into a huge net of fish! Due to the large number of fish, the cranes are running at full load.

  It is impossible for so many fish to be hoisted to the deck at once. Only half of the net can be hoisted to the surface, and then the sailors use harpoons or small nets to drag the bonito to the deck one by one for bloodletting.

  The trawl net can only be hoisted onto the deck at one time after the weight is reduced.

  The weight of bonito is tens of kilograms, so it is much easier to handle than the large-scale tuna. The other three fishing boats also approached to help deal with the situation.

  After 4 hours, nearly 3,000 bonito fish were processed! Everyone is tired of back pain.

   "Boss, I caught a lot of tuna this time. I've caught so much at once. I'm so busy." The old man Oda wiped the sweat from his forehead. Don't look at this old guy as an old man, but he doesn't have to be young at all to work.

   "Yeah, it's too much!" Minano Shuichi was also tired. He has been helping with bloodletting and handling internal organs. He is either squatting to work or bending over. He is really exhausted.

   "Okay, it's already afternoon, take a little break, we'll go longline fishing at night, and get up tomorrow to salvage. Continue to look for fish in the morning!" Nanye Xiu said.

"Yes!"

   Catching tuna is what Minami Hideyoshi hates and loves! The tuna was valuable, of course he liked it. What he hates is that every time he catches tuna, he has to bled and clean the internal organs. It's just too time consuming. And every one of them should be treated like this! Otherwise, the quality and quality of the fish will be affected.
