To catch this school of fish, Qin Shiou chose to use the double-boat purse seine fishing method, and then supplemented it with longline fishing in the back, Sha Ke and the sea monster and others nodded after listening to his order, saying that this was very suitable.

The English name of two-boat-purse-seine-fishing, referred to as double-boat purse seine fishing, has left a glorious page in the history of the world's deep-sea fishing.

In modern times, this technology was developed by Japan, Europe and the United States, but in fact, as early as the mid-17th century, it was created by Chinese fishermen, when many fleets along the coast of Guangdong Province of China used this method to fish, but it was eliminated because the boat was not maneuverable enough at that time, and it was not as convenient and safe as a single boat mobile purse seine net.

Later, in 1837, after the United States began to experiment with two-ship purse seine fishing along the coast of Maine, the two-boat herring fishing industry was gradually formed on the east coast with steam engine fishing boats as the mother ship, and one mother ship led two net-releasing boats to operate. By 1900, the technique of double-boat purse seine fishing was introduced to the coasts of Europe and then to Japan, and it became popular all over the world.

Compared to single-boat trawling, this method is more efficient, but it is more laborious to use, at least it requires two fishing boats with the same performance to use long strip purse seine nets to round up fish, and it is better to have a mother ship in the center, that is, three boats, two of which are independent operating vessels, and one is a mother ship.

Qin Shiou made preparations in advance, he used the Princess as the mother ship, and drove two purse seine boats of the same size from the town to carry out independent operations, and the three ships were deployed at sea, as if an aircraft carrier was fighting with a destroyer, and the scene was very exciting.

Zhong Dajun and Mao Weilong experienced such an occasion for the first time, they followed Qin Shiou to patrol the stern of the ship, and then Qin Shiou entered the cockpit and took the telescope and used the wireless walkie to command the net. The two followed back to the cockpit to watch the scene.

Shaq and a few strong fishermen such as bulls were launched in small boats first, and a series of strong light fixtures were deployed on the surface of the sea, and the deep-sea fish were phototropic, and to concentrate them, it was not only necessary to expel the sperm whales, but also to lure them to the upper waters with strong light.

Before the fisheries ministries of Europe and the United States did not introduce fishing restriction policies. Double-boat purse seine fishing once dominated the Atlantic fishing industry, and mackerel, mackerel, herring, sardines and tuna were almost always caught in this way.

The reason why bluefin tuna is almost cut off is also the reason for this fishing technique.

Qin Shiou used the Poseidon consciousness to accurately locate the movement position of this school of fish, and then ordered the two independent operation boats to move slowly and put the purse seine into the water.

The two independently operated vessels are ordinary small fishing boats, about 14 meters long and 3 meters wide. 5 meters, the main engine is an 80 kW gasoline engine, and the maneuverability is very good. The ship is equipped with a winch machine and a power pulley. This is specially used to lower the net, in fact, there are professional vertical fish finders and locators on the ship, but there is no need for this machine under the command of Qin Shiou.

With such modern technology, the captain of a large fishing boat can still get a high salary, why? The reason for this is that these captains are very good at finding catches and arranging nets, and their eyes and experience are often more useful than fish finders, and they are even more helpful to large fishing vessels.

Under the command of Qin Shiou, the key work of this fishing began. That's the netting.

Slowly but nimble, two independent vessels moved across the surface of the sea, and an extra-long purse seine was pulled apart. The fence was 2,500 feet long. At more than 760 meters, it is the largest purse seine net, which is specially used to catch tuna.

The sea monster in the cab saw the extra-long purse seine slowly unfolded, and he showed a nostalgic expression on his face, and said, "Shet, how long has it been since I saw this damn two-eyed giant?" Oh. Shet, Shet, since the ban on tuna fishing in the Bay of St. Lawrence, I thought I would never see this two-eyed giant again, but I didn't expect to be lucky enough to meet this old fellow today. What a blessing! ”

The Cyclops is the nickname for the oversized purse seine net, as the fishermen want to call it because the wings of the net are long and symmetrical, which can be compared to the two large eyes on a human face.

The counterpart is the cyclops, which is the independent trawl. The fishermen gave their tools all sorts of nicknames, just like the mafia, with a lot of cuts, code words, black words, and so on.

From the two wings to the middle, that is the position of the net bag, the net bag of the double purse seine is wide and short, and its net coat is straightened and elongated about 120 meters, its upper and lower edges are equipped with edge net clothes and upper and lower classes, the upper edge and upper class are attached to the float made of small leather balls, and the lower edge and the lower class are tied with a plumb weight.

In this way, when the two wings of the purse seine are opened, and the upper and lower forks are connected with the trolling gang, the middle part of the upper and lower parts of the net mouth is equipped with a triangular net coat, and the float floats up and the lead sinker sinks down, and a heaven and earth net is opened.

Driven by the big whales, the bluefin tuna school swam into the water in panic, and there was a strong light flashing on the surface of the water, but in fact, this light did not attract all the tuna, but only some of the fish. Tuna have a strong herd nature, and when fish are attracted by bright light, other fish will follow.

The purse seine net was unfurled, and Qin Shiou used the sea god consciousness to observe the swimming situation of this bluefin tuna school, they were swimming from the deep sea to the water, so the formation was the kind of straight up and straight down arrangement, not the usual parallel arrangement of fish stretched the team very long.

The Poseidon consciousness looked down from above, and felt that the current distribution shape of the fish was similar to that of a cylinder, of course, it was not very regular, and some fish were too frightened and still fled around.

These fish will be fish that have slipped through the net, Qin Shiou will ignore them first, and will arrange longline fishing to deal with the fish that have slipped through the net, and now what we have to do is to purse seine and harvest the big fish!

When the fish entered the sea area controlled by the fishing net as a whole, Qin Shiou snapped his fingers and said to the intercom: "Okay guys, prepare to close the door and welcome the harvest!" ”

In addition to the plumb sinker, the lower part of the purse seine is also equipped with a bottom ring, as long as the net is to be closed, it can be controlled to quickly settle and then close the bottom of the net.

The closure of the bottom ring was normal, but it was difficult to close the nets from top to bottom, and the pilot of one of the boats shouted: "Boss, no, the tide is too big, and the net is swinging too much!" ”

The operation mode of double boat purse seine is easy to be limited by the fishing undercurrent, wind current, and tide, one is that the fishing boat operating independently is smaller, and the speed is slower, and the other is that the fishing net is too large, although it is mainly a hollow hole, but the net line is also very thick, and the current impact force is also very large, plus the tuna caught inside is strong and strong, and a careless fishing net will be torn apart!
