To catch this fish, Qin Shiou chose to use a double-boat bagless seine to fish, and then replenish it with longline fishing. Shaq, the sea monster and others nodded after hearing his orders, saying that this is very suitable.

The English name of double-ship bagless seine fishing is to-boat-pue-seine-ishing, referred to as double-ship seine fishing, which once left a brilliant page in the world's ocean fishing history.

This technology was developed in modern times by Japan, Europe and the United States, but in fact, Chinese fishermen created this method as early as the mid-17th century. At that time, many fleets of ships along the coast of Guangdong Province in China used this method to catch fish, but because the ships were not mobility enough at that time and were not as convenient and safe as the single-ship motorized fence, they were eliminated.

Later, in 1837, after the United States began to successfully trial the double-ship seine fishing on the coast of Maine, the oil herring double-ship seine fishing industry was gradually formed on the east coast with steam engine fishing boats as the mother ships, and one mother ship brought two net ships to operate. By 1900, the double-ship seine fishing technology was introduced to the coast of Europe and Japan, and it was completely popular all over the world.

Compared with single-boat trawling fishing, this method is more efficient, but it is more difficult to use. At least it also requires two fishing boats with the same performance to round up fishing with long belt fences. It is best to have a female ship centering order, that is, three ships are required, two of which are independent working boats and one is a female ship.

Qin Shiou made preparations in advance. He used the Princess as the mother ship and drove two seine ships of the same size from the town to operate independently. The three ships were deployed at sea, as if the aircraft carriers were fighting with destroyers. 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 boat. Then Qin Shiou entered the cockpit and took a telescope and directed the Internet with a wireless phone. The two of them also followed back to the cockpit to watch the scene.

Shaq took a small boat with a few strong fishermen, including the bull, and first got into the water. He deployed a series of strong light fixtures on the sea surface. Deep-sea fish have a luminous ray and must concentrate them. Not only do they need to be driven away by sperm whales, but they also need to use strong light to lure them to the upper waters.

Before the fishing ministries in Europe and the United States introduced a restricted fishing policy, the double-ship seine fishing method once dominated the Atlantic fishing industry, such as mackerel, geese, herring, sardines and tuna. Almost all of them were caught in this way.

The reason why bluefin tuna is caught is almost completely unparalleled is also the reason why this fishing technique is.

Qin Shiou used the consciousness of the sea god to accurately locate the moving position of the fish, and then ordered two independent working boats to move slowly and put the fence into the water.

These two independent working boats are ordinary small fishing boats, about 14 meters long and 3.5 meters wide. The main engine is an 80-kilowatt gasoline engine with good mobility. The boat is equipped with a crimping machine and a power pulley, which is specially used to get off the net. In fact, there are also professional vertical fish detectors and positioning instruments on the boat, but it is not available if Qin Shiou directs the machine.

With such advanced modern technology, the captains of large fishing boats can still get high salaries. Why? The reason is that these captains have a good idea of ​​finding fishing catches and arranging networks. Their eyes and experience are often more useful than fish finders and are more helpful to large fishing boats.

Under Qin Shiou's command, the key task of fishing began. That is to lay the net.

Two independent working boats moved slowly but flexibly on the sea surface, and a super long fence was pulled open. The fence had a total of 2,500 feet, or more than 760 meters. It was the largest fence, specially used to catch tuna.

The sea monster in the cab saw the slowly unfolding super long seine. He showed a remembrance expression on his face, saying, "Sheet, how long have you seen this damn eyes giant? Oh, Sheet, Sheet. Since tuna banned in the Bay of St. Lawrence, I thought I would never see this eyes giant again. I didn't expect to be lucky enough to meet this old guy today!"

The binocular giant is the nickname of the super-large seine. Fishermen hope to call it that because the wings of this type of mesh are long and symmetrical left and right, which can be compared to the two large eyes on a human face.

The corresponding one is the Cyclops, which is the independent trawl. The fishermen gave their tools various nicknames, just like the gang of the underworld, with many incisions, code words, slander, etc.

The two wings are closed to the middle. That is the position of the net bag. The net bag of the double enclosure is wide and short, and its mesh is straightened and lengthened by about 120 meters. Its upper and lower edges are equipped with the upper and lower edges, upper edges and upper edges and upper edges are floats made of small balls, while the lower edges and lower edges are tied to the plumb hammer.

In this way, when the two wings of the fence are pulled apart and connected to the traverse through the upper and lower forks, there is a triangular mesh garment in the middle of the upper and lower part of the net port. The float floats up and the lead sinks, and a net of heaven and earth will open.

The bluefin tuna swam on the water in panic, driven by the big whales, and there was a flash of strong light on the water surface. In fact, this light did not attract all tuna, but just attracted some fish. Tuna has a strong herd nature. Fish attracted by the strong light swim to the water, and other fish will also follow.

The fence was unfolded, and Qin Shiou used the consciousness of the sea god to observe the swimming situation of the bluefin tuna. They were swimming from the deep sea to the water surface, so the formation was a straight up and down arrangement, which was not usually arranged in parallel to stretch the line very long.

Looking down from above, the sea god's consciousness felt that the current distribution of fish was similar to cylinders, and of course it was not very regular. Some fish were too frightened and still fled around.

These fish will be fish that are missing the net. Qin Shiou will ignore them first. Later, longline fishing will be arranged to deal with fish that are missing the net. What we need to do now is to fence and harvest the big fish!

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

In addition to the lead sinker, the bottom line of the fence also has a bottom ring. As long as the mesh is to be closed, it can quickly settle and then close the bottom of the mesh ring.

The sealing of the bottom ring is normal, but it is difficult to close the fishing net from top to bottom. The driver on a boat shouted: "Wavess, no, the trend is too big, the net swings too much!"

The operating method of the double-ship seine is easily restricted by undercurrents, wind and trends in the fishing ground. First, the fishing boats operating independently are smaller and have slower speeds. Second, the fishing net is too large. Although it is mainly a large hollow hole, the net line is also very thick and the impact force of the sea current is also very strong. In addition, the tuna caught inside is strong and strong, and if you accidentally get a fishing net, you will be torn apart!
