Zhao Hai and the others used all their strength, and at noon the next day, several ships arrived at Port Vila.
It took until evening to complete the formalities.
Chen Yuan gave them the location and four boats, and went there overnight to put the fishhooks.
There are a lot of fish on the west side of Mangao Island.
Gao He instructed them on the radio how to set the hook. According to the type of fish and the depth of the fish layer, six shallow and four deep.
"The proportion of tuna hooks within fifty meters should be more than half." Zhou Jianguo said: "Tuna hooks should not be placed too deep."
"Are they all small tuna?" Zhao Hai asked.
"There are many small tuna, but few big tuna." Zhou Jianguo added: "Besides, it is night now, and big tuna will also go to the upper waters."
"Okay. Let's put half tuna hooks and half mackerel hooks on the boat."
Zhou Jianguo said "hmm": "There are a lot of fish here, mainly concentrated near the island."
If you put more hooks, you can catch all kinds of fish.
"Specific circumstances."
Zhao Hai was counting the fish catch, but today's fish catch was numerous and miscellaneous, making it difficult to calculate.
In the public mind, pomfret is very cheap, probably just over ten yuan per pound. But pomfret also depends on the species and the way it is processed.
"Fetch some more crushed ice cubes. There are no more ice cubes in the cooling tank."
Zhao Hai took the time to take a look at the processing room: "Prioritize the snapper, and those worthless fish will be processed later."
The ultra-low temperature can lock the moisture in the fish cells, making it especially fresh after thawing.
"In my area, as long as it's valuable fish, any fish that can survive ultra-low temperatures are frozen at ultra-low temperatures," Xu Sandao said.
It is relatively close to the island and there are many fish. Four boats are operating in the same sea area, so they put the fishhook in a roundabout way. That is to say, put a single rope...
However, Zhao Hai did some calculations and found that although there were many fish caught, there were too few valuable fish.
But no matter how you calculate it, if you want to make money, you have to catch more tuna, catch big tuna...
Although their longline fishing boats are more than 40 meters long, they are still not very big. Generally speaking, it is best to cool down the fish caught in tropical waters first and then freeze it.
"I have recycled more than 30,000 meters of rope here, and there is only one tuna that meets the requirements of Dachao, and it is still a big-eyed one." Xu San said: "There are more tuna this time, but the meat quality is very average. They are going to be sold to the factory.
still?"
Zhao Hai smiled, looked at the fixed stainless steel tank behind the workbench, and then looked at the ice room: "How many more ice cubes are needed?"
Zhou Jianguo turned on the radio: "Lao Zhao, Lao Qian, Lao Liu, Lao Xu, how was the harvest?"
After catching the fish, the crew members also had happy smiles on their faces.
At the end of the day today, Chen Yuan and the others found a shoal of tuna in the open sea. There were dozens of them. Judging from the depth, they should be big-eyes. The shoal of big-eyes also swam to the east of Mangao Island. Because there was plenty of food, in the evening
At that time, they all dispersed.
There were too many fish caught today, and the stainless steel tank was almost full of fish.
Chen Yuan and the others were not far away and could see Zhao Hai and his fishing boats.
"Just over 1 ton."
Longline fishing boats do not have low-temperature salt water tanks, so they use ice water to cool down the fish in stainless steel tanks.
The night passed quickly, and the next day came morning.
In fact, 95% of the yellowfin tuna caught worldwide does not weigh more than 70 kilograms. And the majority of yellowfin tuna weighing around 40 kilograms account for the majority.
Chen Yuan got up very early. After washing, he came out and took a look at Zhao Hai's fishing boat. They were already collecting fish hooks.
The mackerel in schools are usually not very big, and after removing the internal organs, they cost more than 2,000 fish per ton.
If a particularly small tuna is still alive after being caught, it is returned to the sea.
"It depends on the amount of catch. If the quantity is large, it will be sent to the factory. If the quantity is small, it will be sent back to the country. If the quantity can be ultra-low temperature, it should be ultra-low temperature as much as possible...it is also sold to canneries and fish processing plants." Zhou Jianguo said.
“No matter what kind of fish, if it’s fresh, the price will always be higher.”
Mackerel is so cheap, at sea, it costs less than two yuan per catty. The workers in the processing room are busy processing valuable fish, and they only process the cheap fish when their hands are free.
The catch is mainly mackerel, pomfret, a small amount of snapper, pipefish, and other fish.
Fish on the upper layer, small fish hooks, mostly small fish, mainly mackerel. There is no need to untie the fish hook, there is a blade on the dry rope to directly cut the branch line. The fish and branch line enter the fish tank and fall directly into the fishing boat
In the processing room, there is a conveyor belt that takes the fish to the processing station.
"Most of the tuna here weigh between 20 and 50 kilograms, and there are also a few kilograms and more than ten kilograms," Zhao Hai said.
Mackerel, sold to Fu'an Fishery, is considered good for 2,000 yuan per ton. Not only Fu'an Fishery, but also sold to other freezer ships that buy fish at sea, the price is similar.
Yellowfin tuna, the price of ultra-low temperature is relatively high. But these are limited to large individual tuna...
Large fishing boats mostly use low-temperature salt water to cool down the live fish before processing them.
Pomfret is also plentiful.
"immediately."
Valuable fish such as snapper are processed directly upon arrival, then packaged and sent to the freezing room or ultra-low temperature fish cabin. The ultra-low temperature cabin has a lower temperature and can freeze the fish as quickly as possible.
The rope lifting machine rotates very quickly, about 5 meters per second.
Zhao Hai stood on the observation deck outside the cockpit. The dry ropes were being recovered below. All the tuna ropes were collected. Now the upper fish hooks were collected...
Xu San laughed and said: "Great harvest. The catch rate of mackerel hooks should be close to 25%. The catch rate of tuna is also very high, 4%, it should be there."
One of the main reasons for the high price of ultra-low temperature tuna is the high cost of ultra-low temperature. Yellowfin tuna is actually not expensive.
In the processing room, the temperature is kept below 6 degrees. This is the tropics, and the fish being shipped has a high body temperature...
There are 11 people in the processing room and it is extremely busy.
Zhao Hai and the others are placing fishhooks over there.
"There are quite a lot of tuna, but most of them are albacore tuna, and there are some big-eye tuna. There are not many yellowfin tuna... and they are not big."
If the meat quality is better, yellowfin tuna of about 40 pounds, conventional ultra-low temperature, will cost five to six thousand US dollars per ton.
The pomfret here is mostly ordinary white pomfret, which is a cheap type of pomfret. But there is also silver pomfret, which is more expensive. The price in China is tens of yuan per catty.
"Priority is given to valuable fish catches."
If there are no ultra-low temperature, sea-frozen yellowfin tuna and ordinary frozen yellowfin tuna, these are mainly used for canning... The price per ton is more than two thousand US dollars.
There are two types of pomfret here. After being sorted and processed, they are placed directly on the shelves, arranged layer by layer, and then sent to the freezing room. In this way, the pomfret in the ultra-low temperature freezing room will still have a good selling appearance after returning to China.
Sea purchase price...
One ton of mackerel costs RMB 3,500, while one ton of white pomfret costs about RMB 6,000. The price of silver pomfret is much higher, but the quantity of silver pomfret is small.
If it's a large yellowfin tuna with medium meat, this kind of tuna is very common in Tuvalu... One hundred kilograms is a lot, almost 40 yuan per kilogram, one piece is 4,000 yuan.
It looks like a bumper harvest today, but it's all worthless fish.
