Zhang Hang and Lu Lu's longline fishing vessel is 24 meters long, with an ice room and an ice fish cabin.
This kind of fishing boat is suitable for coastal fishing. If you want to go far, you have to follow the fleet.
Chen Yuan asked Zhang Hang in detail about the parameters of their fishing boat and calculated them.
Their fishing boats use diesel engines, and their fuel consumption is calculated according to the fuel consumption of yachts. The length is only 24 meters, but the fuel tank is quite large...
For relatively high-intensity work, 21 tons of diesel fuel may only last seven or eight days.
Diesel is not only used for traveling, but also used to generate electricity.
The entire ship's operations are entirely supported by diesel fuel, which consumes a lot of fuel every day.
Chen Yuan then contacted the fishing boats of Lao Zhao and Lao Gao. They also had reserve fuel tanks on board. Because Chen Yuan and his fleet consumed a lot of diesel, Lao Zhao and his two fishing boats all carried diesel...
Their ship is much larger than the Big Fish, and its reserve fuel tank is also larger. The two ships together probably have nearly 60 tons of diesel fuel.
The sun was about to set. Chen Yuan and the others were drinking beer, eating meat, and watching the gorgeous sunset.
"Tomorrow morning." Chen Yuan said.
If the fish is too big, for example, tuna weighing more than 400 to 500 kilograms, it will take nearly ten hours to completely freeze. Larger tuna will take more than ten hours to completely freeze.
"Your speed is a bit slow."
Albacore tuna is very cheap. It is used for canning and is basically chilled. The cost of chilled tuna is low and the price is cheaper.
Nowadays, the fish catch is less, and the workers on the boat are very busy.
Lin Xinhai said ‘hmm’.
The sunset is the most beautiful on the sea.
"We have now increased the purchase price of tuna to 90% of the purchase price of Dongjiang Fisheries. Other fish are still purchased at 70% of the price mentioned before." The purchase price of Dongjiang Fisheries is based on the arrival price.
Fifty percent calculation...
"Aren't you looking for fish?" Yang Xun asked.
"Then catch it and send it to our ship. The price will be 3 yuan cheaper per catty." Lin Xinhai said.
"think."
Chen Yuan thought about it and found that it was indeed the case.
After five o'clock in the afternoon, Lin Xinhai contacted Chen Yuan by radio: "When will Zhang Hang and the others come?"
"Stop talking, we all know that you are notoriously slow." Lin Xinhai said with a smile.
Albacore tuna is considered large if it is over 1 meter.
After running on the sea for most of the day, I found a small school of fish.
Chen Yuan has no feelings about current movies, but likes to watch some old movies. I really feel that old movies still make me feel good when I watch them.
After a movie was played, Chen Yuan turned off the lights: "Sleep."
As for the oil used by fishing boats, it is marine diesel and has a higher fuel value.
Chen Yuan and the others went back to the bedroom early and found a movie from the memory card.
Freeze quickly to lock in the moisture and nutrients in the tuna as quickly as possible, so as to ensure the quality of the tuna as much as possible.
Lin Xinhai continued: "Let's talk about big eye tuna first, third grade is 27, second grade is 31.5, first grade is 36, RMB, 500 grams. Then there is yellowfin tuna, third grade yellowfin tuna is 40.5, second grade is 45, third grade
49.5 yuan. The best tuna is quoted separately...albacore tuna is the cheapest, 10 yuan, 15 yuan, 20 yuan."
If there is a freezing room, the tuna can be stored below minus 45 degrees Celsius on the fishing boat. But if there is no freezing room and it is directly put into the ultra-low temperature fish hold, then the temperature in the fish hold must be at least minus 65 degrees Celsius, and then it needs to be maintained above minus 50 degrees Celsius.
"We haven't started collecting the fish hooks yet. Let's start working after we have eaten." Gao congratulated.
While chatting, Yang Xun and the others woke up. It was now 5:20 in the afternoon.
The temperature in the freezing room is more than minus 70 degrees Celsius, which can freeze tuna more quickly.
Chen Yuan said 'hmm', nodded, and continued to brag with Lin Xinhai and the others. Looking at the time, he took out the pressure cooker and made a potato ton of beef.
Old Hong Kong movies, ghosts fighting ghosts...
"Do you miss your girlfriend?" Zhou Sheng asked.
"We can come here tomorrow morning." Zhang Hang and his crew also have radios on the ship, which are always connected to their channel.
For a short period of time, diesel is sufficient.
"There isn't much work on the fishing boats now. We can't help much if we get on board," Zhou Sheng said.
"The rope releasing machine broke down in the afternoon, otherwise we should have started harvesting the fish by now."
Albacore tuna are small and plentiful.
"That's okay. I hope I can get more yellowfin tuna here. By the way, what's the current price of yellowfin tuna?"
night.
"We don't have ultra-low temperature chambers on board." Zhang Hang said.
"OK."
"Me too……"
"Yes. There are yellowfin tuna, big eye tuna, and albacore tuna." Lin Xinhai said: "The yellowfin tuna are all good in size. The smallest one weighs more than 130 pounds."
Chen Yuan turned his head with an air-conditioned expression on his face: "I miss your sister."
"Go away." Zhao Hai said: "Did you catch more than 130 tuna with just one rope?"
Chen Yuan turned on the exhaust fan, put it down, and lit a cigarette: "We are idle now. Do you want to go to the fishing boat to help?"
"Then let's prepare fishing rods for fishing."
"Okay. From now on, we will set the hook near you."
The albacore tuna caught by Lin Xinhai and the others are only 60 to 70 pounds in size. Most adults weigh around 40 pounds.
"So many." At this time, Gao He also got up and was eating in the cab.
"Ninety percent of the purchase price of Dongjiang Fishery. Zhang Hang, are you here?" Lin Xinhai said.
"exist."
"By the way, this price must be the price after ultra-low temperature freezing." Lin Xinhai added.
As for long-term storage, it would have to be minus 60 degrees Celsius.
It is small in size and widely distributed, and is mostly used to make canned fish. Albacore tuna is also called white tuna and is mostly used to make canned tuna.
Most of the tuna caught this season is bigeye tuna, because the albacore tuna haven't arrived yet.
The sooner the tuna is completely frozen after it comes out of the water, the better.
"I'm not looking for you anymore."
"Turn on the exhaust fan." Zhou Sheng shouted, throwing a cigarette over.
Zhao Hai also spoke and said: "I haven't even finished releasing the second rope here."
"How are yours?"
"The tuna must be delivered to our boat within five hours after it comes out of the water, otherwise the meat quality will deteriorate over time." Lin Xinhai said: "During the preservation process, you have to stuff ice slag into the belly of the fish. The larger the fish, the better."
The fish needs to be delivered to our boat as soon as possible."
"There are quite a lot of fish now. We just collected more than 10,000 hooks and caught more than 130 tuna, including more than 20 yellowfin tuna," Lin Xinhai said.
Have you ever eaten frozen meat?
Like the refrigerator in our home, if a piece of pork is frozen for a long time, it will lose moisture after thawing and the taste will become very bad. But if it is ultra-low temperature and fast-frozen meat, the taste will be much better after thawing naturally.
"I'm thinking of your sister, Xinxin..." Zhou Sheng rolled his eyes.
"Go to bed early. Go to bed early and get up early..."
Zhou Sheng sighed: "I feel like time flies so slowly now. I didn't feel this way when I was in the ocean-going fleet."
"You are too idle. When you go to work on the fishing boat tomorrow, you will feel that time flies by."
