Purse seine fishing is a technical job, can not be hard-pulled brutal, the two fishing boats do slow movement on the sea, soft control fishing nets swing with the undercurrent, delay in closing the encirclement, waiting for Qin Shiou's command.

Piloting the fishing boat are two old fishermen, Zach and Alder, who have made the right choice now, using tacit cooperation to drive the fishing net to rotate, so that even if they can't close the fishing net, they won't let the fish escape.

Qin Shiou frowned and looked ahead and pondered, 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'm a farmer, and I only know a little about crops and livestock, so I can't tell you about this sea thing." ”

Hearing the words of the two, Qin Shiou turned around with a smile and said, "Okay, ask me directly, I'm not in the college entrance examination, it doesn't matter if you chat casually." There are two main ways to operate the purse seine close, one is to enclose the fence and the other is to use the sheet, I have to think carefully about which way to use to close the net. ”

Winter fishing, mainly using the operation mode based on Zhang, the direction of the net according to the wind direction, flow direction and the movement of the fishing object, keep the direction of the net mouth to the fishing object, slow drag for half an hour, keep the net fully extended, all the fish are enclosed and reeled.

But now the wind direction and flow direction are not good for them to collect the net, this method can not be used, Qin Shiou thought about it, and commanded the two fishing boats to use another operation method to fish, which requires more gasoline and manpower, but it is more secure.

Qin Shiou kept issuing orders on the radio, and the following two ships once again set a main ship and a secondary ship, and the two ships had about the same horsepower. Zach's boat has a wider bottom and is more resistant to the waves. So his ship was made the main ship, and Alder's ship was more flexible. I made a side boat.

Zach gave the order, and the fishermen on the boat began to cooperate, they fixed the nets on the starboard deck, and someone watched them, and if the nets were stretched and deformed badly, he had to loosen the nets to prevent them from breaking.

At this time, the upper and lower sections of the purse seine are fully deployed, with the right wing in front and the left wing behind. The main ship anchors and stops, while the auxiliary boat turns the starboard side facing the main ship and turns while reeling in the net.

Qin Shiou monitored the merging of the fishing nets in the water through the consciousness of the sea god, and when he reached the sea area where the current speed was relatively gentle, he ordered the nets to be collected.

At this time, the main and auxiliary ships gradually approached, and the two ships met on the port side, and the auxiliary ship handed the towing plan, the support plan, and the belt program to the main ship, and then adjusted the position of the ship, and turned to retract the net wings on both sides with the main ship.

There were winches on both ships. As the winch turned, the steel cable dragged the net and began to retract.

The Melon Princess was far away, and Mao Weilong and Zhong Dajun couldn't see the situation on the two ships clearly, and they didn't understand why the fishermen around them had serious expressions.

Qin Shiou immediately explained to them. Bluefin tuna is a large wild fish that can grow up to three or four meters long because of its bomb-shaped size. If they charge with all their might, the impact is about the same as a bomb. If the nets are not good, they may shred the nets.

Chung Dae-jun was in disbelief. He pointed to the fishing net and said, "Damn, this fish has so much strength?" I see that the rope of the fishing net is the thickness of my thumb, even a car can catch 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 continue to attack." When the impact is superimposed, the damage to the fishing net is relatively great. ”

In this case, there is no need to keep the net mouth and flow direction consistent in the direction of the purse seine net, and during the net collection process, the two boats will drag the net downstream for a period of time, with the help of the tide, so that the net can be fully opened to increase the living space of the fish, and try not to panic the bluefin tuna.

The three boats took almost all the fishermen with them this time, and more than 50 people participated in the fishing operation, of which except for Zach and Alder, who each brought five people to lower and collect the nets, and the rest were all on the Melon Princess.

They are fully equipped, like soldiers waiting for the rest of their lives, and at the sound of an order, the whole army will assault!

And the order they were waiting for was to prepare for longlining.

When the two boats began to reel in their nets, they left the area with the current, and there were some fish that slipped through the net, and these fish were caught by longlining.

Qin Shiou waved his hand, and the fishermen sorted out the coiled trunk lines on the stern of the boat, and they began to work.

Longline fishing is one of the most important types of fishing tackle, with the widest distribution and the highest quantity and yield. This thing is to tie a number of equally spaced branch lines on a main line, with hooks and bait at the end, and use floating and sinking devices to lay them on the surface, middle and bottom layer, and connect a series of hooks below to attract the catch.

Generally speaking, tuna like to feed against the current, so that the direction of the line is perpendicular to the direction of the current, which can better attract tuna.

Longline fishing is also a very manpower fishing method, a trunk line is often five or six kilometers long or even longer, such as the melon princess on the trunk line is eight kilometers, there is a branch line separated by ten meters, and personnel need to hook hooks and bait on the connected branch line.

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

But this work must be carried out on the spot, it is impossible to hang hooks on the line in advance, and the eight-kilometer-long trunk line cannot be coiled up at all, and once coiled together, it will cause rope entanglement, which cannot be untied at that time.

The Melon Princess moved at a constant speed of six knots, and the fishermen worked quickly at the stern of the boat, like a production line, and the main line fell into the sea, and the hook and bait had to be hung on the spur line before falling overboard, otherwise the resources of this rope would be wasted.

In addition to the hook and bait, there are also people who are responsible for attaching floating balls, which are about one branch line every ten meters, and two floats are added every five branches to maintain buoyancy. And every time the float is installed, a pressure alarm is also installed.

This alarm is the most important, when the fish are hooked, they will pull the branch line and sink down, the alarm will feel the pressure change, it will flash a dazzling light, so that the fisherman can find the fish on the bait in time to catch them.

Tuna are fierce and fierce, and if they don't catch them in time, these guys will find a way to escape. Even if they don't escape, they will struggle frantically to entangle the main line, and once the hooks become tangled in each other, it will add a lot of labor to the fishermen.

Twenty fishermen are divided into two groups, one working and the other resting, like mechanical arms on an assembly line, skillfully and precisely hanging hooks, bait, floats and alarms on ropes.
