Zhao Hai and the others finished harvesting the fish and prepared to take the bait again.

The Big Fish and Gao Lao Gao also came over.

"How's the catch?" Radio channel, Lin Xinhai asked.

"The amount is great and the harvest is ...... So so. Zhao Hai said.

"It's all tuna between 20 catties and 70 catties, and there are more tuna tuna from 30 catties to 50 catties. These tunas have less oil. Qian Degui said.

"The amount of tuna, it's not big." Luo Hao's voice came out.

"The catch rate of tuna is about 4-4.5. I put 2,000 tuna hooks here, and there are 84 tuna that weigh about 40 pounds. There were hundreds of tuna caught in the shallow water hooks, but many were too small, leaving only a hundred and fifty. Qian Degui said.

"How big is a baby tuna?"

"The ones left are more than ten catties, and some are more than twenty catties. The average weight is about 16 pounds a tail. ”

"The meat is not good?"

"Low in grease."

Luo Hao asked Xu San again, and they were not much different.

"If the tuna is low in fat, less than 30 catties, we are ready to sell it to canning factories. More than 30 pounds will be sent back to China...... Anyway, I'll give you 50% of the selling price, okay. Luo Hao asked.

"Okay." Qian Degui said.

"Canned tuna, how much is 1 ton?"

"The canning company I contacted here, yellowfin tuna, is $2,260 per tonne. Albacore tuna and bigeye are slightly cheaper, but also around $2,000. ”

The radio channel was silent for a while.

Luo Hao said again: "For small tuna, we give 1,200 US dollars per ton." ”

"Okay." Zhao Hai opened his mouth: "What is the approximate price of tuna over 30 catties?" ”

"Ultra-low temperature, freshness level 1, it should be more than ten yuan and 1 catty, RMB. Specifically, it is necessary to see the price after the port. Luo Hao said: "If the oil is very low, it can only be sent to the factory." ”

"Okay." Liu Sidao.

Qian Degui calculated it, more than a dozen yuan and 1 catty......

There are still a lot of tuna caught today, and if you use 30 catties as the dividing line, it will be about 4,500 catties. If it is more than ten dollars and 1 catty, then it will earn back the cost.

Qian Degui also said: "Okay." ”

"Try to find some good punctuation in the back, mainly fishing tuna."

Luo Hao let out an 'um' sound.

It's more than 20 catties, 30 or 40 catties of tuna, which is considered a small tuna. In the tuna fishing industry, there are not many tuna of hundreds of catties.

For example, the total catch of yellowfin tuna in the Indian Ocean is about 400,000 tons, but the actual catch should be greater than the quota. The vast majority of yellowfin tuna in the Indian Ocean are thirty or fifty pounds of individuals.

Small tuna are active on the surface and are easy to catch.

Big tuna, at every turn, is two hundred meters below the water, or even hundreds of meters deep......

Six fishing boats continued south and began to hook.

The fishing boat had plenty of bait (mackerel), and under Luo Hao's command, the six fishing boats took their own positions, lowered the auxiliary boats, and began to hook them.

The current time, after four o'clock in the afternoon, is mainly in time for the opening period of the evening.

With the help of auxiliary boats, each fishing boat lowered two ropes. Among them, the short rope extends to the open sea under the pull of the auxiliary vessel. The long rope still has a certain twist......

When they came to Waruatu, Chen Yuan's fishing boat was not very useful.

Here, there are many fish, and the location of the hook is easy to find. Both are large islands, and the best location is in the sea between the two islands. There is a clear flow of water in the sea between the islands, and there are many fish.

For Chen Yuan, it was easy to find fish, so they were idle.

There are many fish and the catch rate is high.

The little nanny also drove out of Port Vila and worked with the fleet.

There are too many small fish, and the processing room of the longline fishing boat is too busy. For some cheap small fish, longlines are frozen and then kept fresh with ice.

The fishing boat retracts two ropes a day, with a total length of 200,000 meters. But the length of a rope is only 110,000 meters...... Release 110,000 meters of rope, which is about 4 hours. After the rope is released, the fishing boat approaches the nanny and carries the previous catch to the nanny's boat.

These catches are mainly some worthless catches, mainly small tuna, wolffish, bonito, etc.

Some small fish, such as mackerel, are not caught when there is enough bait.

Small tuna, in turn, is dominated by albacore tuna, which is the most abundant.

Now, they also mainly fish for tuna, only albacore, and the catch per day in a boat is usually more than 6 tons, and more than 10 tons.

Many people think that tuna is rare, but it depends on the species. The number of bluefin tuna is relatively small, but albacore tuna and yellowfin tuna are abundant.

Among them, albacore tuna is one of the most caught fish in the world, ranking within the top ten.

Albacore tuna is relatively small, and the large one is more than 40 catties. As a commercial fish, there are not many requirements for the fishing regulations for albacore tuna, and it is not particularly small.

】

The fleet began to operate in an assembly line mode, and the hooks were placed more secretively.

200,000 meters of rope, about 22,000 hooks. By precisely measuring the temperature of the water column, as well as the phases of the moon, the catch rate can reach three percent.

Bigeye tuna, yellowfin tuna, albacore...... The depth of these three tuna habitats is mainly related to the water temperature.

And then there's the moon phase......

The moon phase and the different timing of longline fishing have an impact on the catch rate of bigeye tuna and yellowfin tuna.

In other words, in addition to the water temperature, the depth of the longline hook should be determined according to the moon phase.

Albacore tuna is seasonal, and at this time, there are more albacore tuna in Varouatu. This is an upper-layer fish, and it is relatively simple to hook it.

Yellowfin tuna and bigeye are active and overlapping, but they are not in the same water layer.

Three percent is already a pretty good catch. Like some longline fishing boats that fish for big tuna, the catch rate is calculated in thousands. That's about 2 out of 1,000.

Chen Yuan's catch rate is mainly due to the fact that they have found a sea area with more fish. Instead of taking the bait everywhere.

Six boats, during the operation, the total catch of fish per day is about 70 tons. One of the big tuna, and some valuable fish, are left in the ultra-low temperature of the longline fishing boat.

Small tuna and cheap fish, all delivered to the little babysitter.

"Hey, Chen Yuan." Early this morning, Chen Yuan received a call from Wang Peng.

"Here, what are you doing?"

"If you have time, take me to Port Vila."

"Free." Chen Yuan smiled and said, "Go over immediately." ”

Wang Peng has been on the ship for several days and is about to return to China.

Chen Yuan drove the boat and went over to pick up Wang Peng: "How many fish are on the little nanny?" ”

"More than three hundred tons." Wang Peng said: "It's all worthless catches. ”

"Where are you going to sell it?"

"In the maritime trade, a company in Guangdong, they have a factory in Fiji, which mainly does canned fish." Wang Peng said.

The fish on the little nanny is not worth much, and if it is sent back to China, the journey is too far to be cost-effective.
