Golden Fishery

To catch this school of fish, Qin Shiou chose to use two boats to fish with a purseless seine, and then supplemented with longline fishing. Shaq, Kraken and others nodded after listening to his order, saying that this is very suitable.

The English name of double-vessel purse-free seine fishing is --purse--, referred to as double-vessel seine fishing, which once left a glorious page in the history of world ocean fishing.

This modern technology was developed by Japan and Europe, but in fact, as early as the middle of the 17th century, Chinese fishermen created this method. At that time, many fleets along the coast of Guangdong Province in China used this method to fish, but due to the maneuverability of the ships at that time The performance is not enough, and it is not as convenient and safe as the single-boat motorized seine, so it is eliminated.

Later, in 1837, the United States began to try two-ship seining herring off the coast of Maine. Net boat operation. By 1900, the two-boat purse seine fishing technique was introduced to the coast of Europe, and then to Japan, and became popular all over the world.

Compared with single-vessel trawling, this method is more efficient, but it is more laborious to use. At the very least, it also requires two fishing boats with the same performance to use long belt purse seines to round up fish, and it is best to have one The centering order of the mother ship means that three ships are required, two of which are independent operation ships and one is the mother 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 carry out independent operations. The three ships were deployed at sea, as if an aircraft carrier was leading a destroyer to fight. 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 with a telescope and used a wireless communicator to command the net. The two also followed back to the cockpit to watch the scene.

Shaq took the bull and several other strong fishermen into the water in small boats first, and deployed a series of strong light lamps on the sea surface, because deep-sea fish are phototropic. To concentrate them requires more than expelling sperm whales. Bright lights are also used to lure them to the upper waters.

Before the Ministry of Fisheries of European and American countries introduced fishing restriction policies, the double-vessel seine fishing method once dominated the Atlantic fishing industry, such as mackerel, trevally, herring, sardines and tuna, which were almost all caught in this way.

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

Qin Shiou used the sea god consciousness to precisely locate the moving position of the fish school, and then ordered the two independent operation boats to move slowly and put the seine net into the water.

The two independent operating 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 maneuverability. The boat is equipped with winches and power pulleys, which are specially used for netting.

In fact, there are professional vertical fish finders and locators on board, but with Qin Shiou directing them, they are useless.

With modern technology so advanced, the captain of a large fishing vessel can still get a high salary. Why? The reason is that these captains are very good at finding catches and arranging networks. Their eyes and experience are often more useful than fish finders, and they are more helpful to large fishing boats.

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

Two independent operating ships moved slowly but flexibly on the sea surface, and an ultra-long seine net was pulled apart. The total length of this fence is 2,500 feet, or more than 760 meters. It is the largest of the seines and is specially used to catch tuna.

The sea monster in the driver's cab saw the super long seine slowly unfolding, and he showed nostalgic expression on his face, saying: "Snow, how long has it been since I saw this damn giant with two eyes? Oh, Xue, Xue, since After tuna fishing was banned in the Gulf of St. Lawrence, I thought I would never see this giant-eyed man again. I didn’t expect to be lucky enough to meet this old man today, what a blessing!”

Two-eyed giant is the nickname for oversized seines. Fishermen prefer to call it that because the nets have long, symmetrical wings. It can be compared to two big eyes on a human face.

Corresponding to the Cyclops, that is independent trawl. Fishermen have all sorts of nicknames for their tools, like a gangster mouth, with lots of cuts, code words, slang words and the like.

From the two wings to the middle, that is the position of the mesh bag. The mesh bag of the double fence is wide and short, and the net is about 120 meters long when straightened. Its upper and lower edges are equipped with edge nets and The upper and lower lines, the upper edge and the upper line are attached with floats made of small balls, while the lower edge and the lower line are tied with plumb weights.

In this way, when the two wings of the seine net are pulled apart, the upper and lower fork lines are connected with the drag line, and the upper and lower middle parts of the net mouth are equipped with triangular net clothes.

Driven by the big whale, the school of bluefin tunas frightened and swam towards the water. There was a strong light flashing on the surface of the water. In fact, the light did not attract all the tunas, but only a part of the fish. Tuna has a strong herd, and the fish that are attracted by the strong light swim to the water, and other fish will follow.

The seine net was unfolded, and Qin Shiou observed the swimming situation of the school of bluefin tuna with the consciousness of the sea god. They swim from the deep sea to the water surface, so the formation is the kind of straight up and down arrangement, not the usual parallel formation of fish schools to pull the team Stretched very long.

Looking down from above, the Poseidon consciousness feels that the distribution of the fish school is similar to a cylinder. Of course, it is not very regular. Some fish are too frightened, so they still flee to the surroundings.

These fish will slip through the net, Qin Shiou will ignore them, and will arrange longline fishing to deal with the fish that slipped through the net later. What we need to do now is to seine the net and harvest the big fish!

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

The lower outline of the seine net is equipped with a bottom ring in addition to the lead pendant. As long as the net gear is to be closed, it can be controlled to settle quickly and then close the bottom of the net circle.

The sealing of the bottom ring was working normally, but it was more difficult to close the fishing net from top to bottom. The driver of a boat shouted: "No, the tide is too big, and the net swings too much!"

The operation method of the two-boat purse seine is easily restricted by the undercurrent, wind current and tidal current in the fishing ground. First, the fishing boats operating independently are small and the speed is relatively slow. Second, the fishing net is too large. It is thick, and the force of the impact of the ocean current is also very strong. In addition, the tuna rounded up inside is strong and strong. If you are not careful, the fishing net will be torn to pieces!
