Sea-hunting: With the system in hand, my eyes are the ruler

They clearly had a fish finder on their boat, so why weren't they staring at it?

Although Brother Cheng has many ideas, he is still relatively clear about his own positioning.

At best, he is a boat driver.

Jiang Han is the captain of the ship, and he drives the ship however Jiang Han tells him to.

He drove the boat as Jiang Han said, and under Jiang Han's step-by-step command, their boat finally arrived at where Jiang Han was.

Jiang Han continued to direct, "Adjust the boat speed to 8-9 knots, head southeast, and the crew will begin to release the line."

There are rows of hooks attached to the long fishing line, and small fish are hanging on the hooks.

This is why longline fishing boats are so labor-intensive.

It takes time to organize the line, it takes time to organize the hooks, and it takes time to hang the bait.

Now laying out the lines also requires manual participation.

More manual labor is required when pulling the wire.

The crew members were standing at their workstations pulling the lines, which were close to the edge of the ship and they could fall if they were not careful.

Throughout the long history of fishing around the world, there have always been fishermen who have fallen off the boat.

Many fishermen who fall into the water cannot be rescued even if they want to.

Fortunately, the security measures on his ship are good.

When the crew started working, Jiang Han made a special check to make sure that every crew member had a life rope hung on them.

This way, even if they accidentally fall, the rope can hold them back.

After all the hooks were released, Jiang Han stopped the boat and let it float on the sea.

Doing so can not only save fuel, but also avoid disturbing the fish while the fishing boat is working.

Jiang Han carefully observed the situation on the seabed.

Longline fishing can also be divided into two methods: bottom fishing and suspended fishing.

Jiang Han used bottom fishing this time because he wanted to catch silver cod.

Silver cod is also an Antarctic toothfish.

Jiang Han had caught some in the East China Sea before. Compared to the small number of silver cod in the East China Sea, there were far more silver cod in the Indian Ocean.

This kind of deep-sea silver cod is sold in supermarkets.

Fresh fish fillets can be sold for more than 400 yuan per kilogram.

Of course, the purchase price will be much lower, and the whole fish can be sold for more than 200 yuan per kilogram.

The weight of a silver cod is generally around 8 to 16 jin, and a larger one can reach 40 to 60 jin.

Where Jiang Han stopped the boat, the weight of the silver cod was over 20 kilograms.

That means he can sell a silver cod for at least 4000 yuan.

His boat is a longline fishing boat, which is different from a trawler.

The trawler drags its net over, catching all kinds of fish.

Longline fishing boats cause much less harm to fish. When ocean-going longline fishing boats go out to sea, they only target valuable fish.

For example, the silver cod he saw today, the tuna, and the high-end grouper...

Jiang Han felt that it was almost time, so he used the radio equipment on the ship to ask the crew to pull up the hook.

Old Zheng, who was in charge of the hooking, thought he had misheard. He ran over to confirm with Jiang Han, "Captain, are you sure you want to hook now?"

Jiang Han nodded, "I'm sure."

Old Zheng opened his mouth in surprise. Looking at Jiang Han's young face, he felt that Jiang Han must have little experience.

"Captain, have you ever used longline fishing before?"

"Yes, when I was driving a small boat, I used to put down several baskets of hooks to catch cutlassfish."

The longline fishing used at that time cannot be compared with the longline fishing used on modern fishing vessels today.

All the equipment on this boat is specially designed for longline fishing.

Lao Zheng wiped his sweat. "Captain, since you've used longline fishing before, you should know what's going on, right? It's only been a short time. Even for eels, it takes one to one and a half hours to reel in the hook. Tuna takes two hours, and croaker and hairtail take even longer. You're using a bottom line now, and the line is below 500 meters. No matter what fish you're catching, you'll have to wait a while, right?"
