Seal fishing is a technical job, and you cannot be forced to do it. Two fishing boats move slowly on the sea surface, gently controlling the fishing nets swing with the undercurrent, and they are not encircling for a long time, waiting for Qin Shiou's command.

The two old fishermen who drove the fishing boat were Zach and Alder. Their choices were very correct now. They used tacit cooperation to drive the fishing net to rotate, so that even if they could not surround the fishing net, the fish would not escape.

Qin Shiou frowned and looked forward thinking hard. Zhong Dajun didn't dare to disturb him, so he asked Mao Weilong in a low voice: "What's wrong? Do you know what to do now?"

Mao Weilong scratched his head and said, "I don't understand. I am a farmer and I only have some understanding of crops and animals. I can't tell you what's happening at sea."

Hearing the words of the two, Qin Shiou smiled and turned around and said, "Okay, ask me directly. I'm not in the college entrance examination, so it doesn't matter chatting casually. There are two main ways to close the fence. One is mainly based on the fence and the other is based on the fence. I have to think carefully about which method to use to close the web."

In winter, fishing mainly uses a main operation method. The direction of the net is placed according to the wind direction, flow direction and the direction of the fishing object. The net port is slowly dragged for half an hour to keep the net fully extended and the fishing school is surrounded and closed.

But now the wind direction and flow direction are not good for them to close the net, so this method cannot be used. Qin Shiou thought about it and directed the two fishing boats to use another operation method to fish, which would require more gasoline and manpower, but it is more secure.

Qin Shiou kept issuing orders on the radio, and the two ships below set up a main ship and a sub-ship. The two ships had about the same horsepower. Zach's bottom was wider and his ability to resist waves was stronger. So his ship became the main ship, and Alder's ship had better flexibility and became the sub-ship.

At Zach's order, the fishermen on the boat began to cooperate with the work, and they fixed the net on the starboard deck. Someone specifically watched. If the fishing net was stretched and deformed, he had to relax the fishing net to prevent the fishing net from breaking.

At this time, the upper and lower lines of the fence are fully expanded. The right net wing is in front and the left net wing is behind. The main ship breaks down and the secondary ship faces the starboard side facing the main ship, and then rotates while closing the net.

Qin Shiou monitored the convergence of the fishing nets in the water through the consciousness of the sea god. When he arrived at the sea area where the current flow was relatively light, he ordered the net to be closed.

At this time, the main and auxiliary ships gradually moved closer. The two ships met on port side. After handing the auxiliary ship to the main ship, they adjusted the ship's position and turned to pull the net wings on both sides with the main ship.

Both ships had winches on them. As the winch turned, the steel cable dragged the fishing net and began to gather.

The Melon Princess was far apart, and Mao Weilong and Zhong Dajun couldn't see clearly the situation on the two ships, and did not understand why the fishermen around him had serious expressions on their faces.

Qin Shiou immediately explained to them that the bluefin tuna is a big wild fish. They can grow up to three or four meters long because they are in the shape of a bomb. If they exert force, the impact force is really similar to a bomb. If the net is not good, they may be torn to pieces by the fishing net.

Zhong Dajun was incredible, and pointed to the fishing net and said, "Damn, this fish has such a strong force? I see that the net rope of the fishing net is as thick as my thumb. Even a car can live in the net, right?"

Qin Shiou said: "If it's just one impact, then the fishing net is not afraid, but once the bluefin tuna goes crazy, they will continuously impact. When the impact force is superimposed, it will be more destructive to the fishing net."

In this case, the direction of the fence does not need to keep the net port and flow direction consistent. During the net collection process, the two ships will drag the fishing net along the current for a period of time. With the help of the trend, the net tool will be fully opened to increase the living space of the fish, and try not to let the bluefin tuna feel panic.

The three ships went to sea this time and brought almost all the fishermen. More than fifty people participated in the fishing operation. Except for Zach and Alder, five people were each taken to get off the net and close the net, the rest were all on the Melon Princess.

They were fully equipped, like soldiers waiting for the battle. With the order, the entire army attacked!

The order they were waiting for was to prepare for longline fishing.

When the two ships started to close the net, they left the sea area along the current. There were some fish that were missing from the net around them. They relied on longline fishing.

Qin Shiou waved his hand, and the fishermen sorted out the trunk lines on the stern of the boat, and they started working.

Longline fishing is the most important operation method in fishing gear, with the widest distribution surface and the highest quantity and output. This thing is to tie many equal-distance branch lines on a trunk line, with hooks and bait at the end. It is laid on the surface, neutralize the bottom layer with floating and sinker devices, and connect a series of fish hooks below to attract the catch to hook.

The direction of the line release is preferably cross-flow or oblique flow. Generally speaking, tuna likes to feed against the current, so that the direction of the line release is perpendicular to the direction of the sea current, which can better attract tuna.

Longline fishing is also a very test of manpower. A trunk line is often five or six kilometers long or even longer. For example, the trunk line on the Melon Princess is eight kilometers, and there is a branch line ten meters above it. People need to hook and bait to the connected branch line.

In other words, there are 800 branches on a trunk line, and two hooks in front and behind a branch line. A total of 1,600 hooks and bait are hung, which is quite a lot of work!

However, this work must be carried out on site. It is impossible to hang hooks online in advance. The eight-kilometer-long trunk line cannot be rolled up at all. Once it is rolled together, it will cause rope entanglement, which will not be able to be untied at that time.

The Melon Princess advances at a constant speed of six knots. The fishermen work quickly at the stern, like a production line. The main line falls into the sea. They must hang hooks and baits on the branch line before falling into the water, otherwise the resources of the rope will be wasted.

In addition to the hook and bait, there is also someone responsible for hanging float balls. There is a branch line every ten meters, and two floats are required to maintain buoyancy at about every five branch lines. Every time two floats are installed, a pressure alarm is required.

This alarm is the most important thing. When the fish are hooked, they will pull the branch line down. The alarm feels the pressure changes and will flash a dazzling light, so that the fisherman can find the fish in time to catch them.

Tunas are fierce and fierce. If they cannot be caught in time after they are hooked, these guys will find a way to escape. Even if they do not escape, they will struggle wildly to lead the trunk line to entangle. Once the hooks are entangled into a ball, it will add a lot of labor to the fishermen.

Twenty fishermen were divided into two groups, one worked and the other rested. They were like mechanical arms on the assembly line, skillfully and accurately hanging fish hooks, baits, floats and alarms on the ropes.
