Zhao Hai and the others finished harvesting the fish and prepared to set the hook again.
Big Fish and Gao Laogao also came.
"How was the fish?" Lin Xinhai asked on the radio channel.
"The quantity is huge, and the harvest is... average." Zhao Hai said.
"They are all tuna between 20 kilograms and 70 kilograms, and there are more tuna between 30 kilograms and 50 kilograms. These tuna have less oil." Qian Degui said.
"How big is the amount of tuna?" Luo Hao's voice came out.
"The catch rate of tuna is about 4-4.5. I put 2,000 tuna hooks here, and 84 tuna came up, weighing about 40 kilograms. There were hundreds of tuna caught in the shallow water hook, but there were many
It's too small, only a hundred and fifty are left," Qian Degui said.
“How big are the baby tuna?”
"The ones left behind are all more than ten kilograms, and some are more than twenty kilograms. The average weight is about 16 kilograms per tail."
Small tuna is mainly albacore tuna, which is the largest in number.
"Try to find better punctuation points later, mainly fishing for tuna."
With 200,000 meters of rope and about 22,000 fish hooks, the fish catch rate can reach 3% through precise techniques such as water layer temperature and moon phase.
"Low grease."
The moon phase and different line casting times in longline fishing have an impact on the catch rates of bigeye tuna and yellowfin tuna.
Luo Hao asked Xu San and the others again and found that they were not much different.
Luo Hao said 'hmm'.
In other words, in addition to water temperature, the depth of the longline fishing hook must also be determined according to the moon phase.
Qian Degui also said: "Okay."
"Hello, Chen Yuan." Early this morning, Chen Yuan received a call from Wang Peng.
Big tuna can always be found at depths of one to two hundred meters, or even hundreds of meters...
Then there are the moon phases...
For Chen Yuan and the others, finding fish was easier and they were free.
"The quality of the meat is not good?"
When they arrived in Varuatu, Chen Yuan and his friends found that their fishing boat was no longer of much use.
The fleet has started an assembly line operation mode, and the placement of fishhook is also relatively secretive.
These fish catches are mainly worthless fish catches, mainly small tuna, wolffish, bonito, etc.
"I'm free." Chen Yuan smiled and said, "I'll be there right away."
The fishing boats had enough bait (mackerel). Under the command of Luo Hao, the six fishing boats took their respective positions, put down the auxiliary boats, and began to set the hook.
The fish catch rate of Chen Yuan and the others was mainly due to finding areas with more fish instead of setting hooks everywhere.
Among them, albacore tuna is one of the most caught fish species in the world, ranking among the top ten.
Small tuna and cheap fish are all sent to the nanny.
There is still a lot of tuna caught today. If we use 30 kilograms as the dividing line, it will be about 4,500 kilograms. If it costs more than ten yuan per kilogram, the cost will be recovered.
Yellowfin tuna and bigeye tuna have overlapping activities, but they are in different water layers.
During the operation of six boats, the total daily fish catch was about 70 tons. Among them, large tuna and some valuable fish were left in the ultra-low temperature of the longline fishing boat.
Albacore tuna is relatively small, with a large one weighing more than forty pounds. As a commercial fish, there are not many requirements for fishing standards for albacore tuna, as long as it is not particularly small.
A fish catch rate of three percent is already very impressive. Like some longline fishing boats that catch large tuna, the fish catch rate is calculated on a per thousand basis. It is probably within two thousandths.
Wang Peng has been on the boat for several days and is going back to China.
Bigeye tuna, yellowfin tuna, albacore tuna...the habitat depth of these three types of tuna is mainly related to the water temperature.
"Okay." Liu Sidao.
The radio channel was silent for a while.
"The canning company I contacted here, yellowfin tuna, is US$2,260 per ton. Albacore and bigeye tuna are slightly cheaper, but they are still around US$2,000."
There are many fish here, and the place to set the fishhook is easy to find. They are all big islands, and the best location is the sea area between the two islands. The water flow in the sea between the islands is obvious, and there are more fish.
"If you have time, take me to Port Vila."
With the help of the auxiliary boat, each fishing boat lowered two ropes. The short ropes were pulled by the auxiliary boat and extended out to sea. The long ropes still had some twists and turns...
"Okay." Qian Degui said.
Luo Hao added: "For small tuna, we will give you US$1,200 per ton."
Qian Degui calculated that it costs more than ten yuan per catty...
The current time is after 4 pm, mainly to catch up with the opening period in the evening.
Six fishing boats continued south and began to set hooks.
For example, the total fishing quota for yellowfin tuna in the Indian Ocean is about 400,000 tons, but the actual fishing volume should be greater than the quota. The vast majority of yellowfin tuna in the Indian Ocean weigh only thirty to fifty kilograms.
Small tuna are active on the surface and are easy to catch.
Many people think that there are very few tuna, but it depends on the species. The number of bluefin tuna is relatively small, but the number of albacore and yellowfin tuna is large.
Now, they also mainly fish for tuna, only albacore tuna. The daily catch of a boat is usually more than 6 tons, and as many as more than ten tons.
"Ultra-low temperature, freshness level 1, should cost more than ten yuan per catty, RMB. The specific price depends on the price after the port." Luo Hao said: "If the oil is particularly low, it can only be sent to the factory."
Chen Yuan drove the boat and went to pick up Wang Peng: "How many fish are there on the little nanny?"
Tuna weighing more than 20 kilograms, thirty or forty kilograms are considered small tuna. In the tuna fishing industry, there are not many tuna weighing hundreds of kilograms.
"Canned tuna, how much does it cost per ton?"
Albacore tuna is seasonal. At this time, there are more albacore tuna in Varuatu. This is a top-level fish, and the hook is relatively simple.
The fishing boat retracts and releases two ropes every day, with a total length of 200,000 meters. But the long rope is only 110,000 meters... It takes about 4 hours to release 110,000 meters of rope. After releasing the rope, the fishing boat goes to the little nanny.
Get close and carry the previous catch to the little nanny boat.
"Here, what are you doing?"
There are many fish and the fish catch rate is high.
"Okay." Zhao Hai said: "What's the approximate price for tuna over 30 kilograms?"
Some small fish such as mackerel are not caught if there is enough bait.
The little nanny also sailed out from Port Vila and worked with the fleet.
There are so many small fish that the processing rooms of longline fishing boats are overwhelmed. For some cheap small fish, longlines are frozen and then kept fresh with ice cubes.
"If the fat of the tuna is low, we will sell it to canning factories if it is less than thirty kilograms. If it is more than thirty kilograms, we will send it back to the country... Anyway, I will give it to you at 50% of the selling price, okay." Luo Hao asked.
.
"More than three hundred tons." Wang Peng said: "They are all worthless fish."
“Where are you going to send it for sale?”
"In maritime trading, there is a company in Guangdong. They have a factory in Fiji, mainly engaged in canned fish processing." Wang Peng said.
The fish on Little Nanny is worthless. If it is sent back to China, the journey is too far and it is not cost-effective.
