The thermometer showed that the temperature inside the processing room was only 7 degrees Celsius.
The workers were busy inside, but they were sweating.
The conveyor chute brought in fish one after another, and many fish were left on the ground, too late to be processed.
Chen Yuan and the others went to the ultra-low temperature chamber, which mainly contained tuna, swordfish and marlin.
After these fish are put on the boat, the gills and tails are cut off within 5 minutes, the internal organs are cleaned, and then sent to the freezing room to quickly freeze hard, and then transferred to the ultra-low temperature freezing ship, which can ensure the freshness of the fish to the greatest extent.
The ultra-low temperature chamber was very cold. After entering it for a while, ice shards appeared on Chen Yuan's eyebrows.
"Can you tell the difference between marlin and swordfish clearly?" Zhou Sheng asked, looking at the jaw sword of a big marlin.
"It's easy to distinguish."
Sailfish, marlin, swordfish, some people are stupid and can’t tell them apart.
Swordfish belongs to the order Perciformes and family Swordfish.
Both swordfish and marlin belong to the order Perciformes and the family Sailfish.
Judging from the jaw sword, swordfish has the longest jaw sword, and its length can account for 1/3 of the body.
Although swordfish and marlin also have jaw swords, their length is obviously much shorter than swordfish.
Judging from the dorsal fin, the dorsal fin of swordfish is small, has a short base, and is triangular in shape.
The dorsal fin of swordfish is tall, soft and sail-shaped.
The dorsal fin of marlin is long, but only the front end is high.
The more difficult to distinguish is probably marlin and swordfish.
Kiribati is tropical and located on the equator, so there are many marlins. It cannot be said that there are no swordfish, but there are very few.
Swordfish and marlin are less common in the market and are more difficult to catch, but their prices are much lower than those of tuna.
Sailfish and marlin are ultra-low temperature frozen, and the larger ones can reach the price of small yellowfin tuna. If they are fatter, they can catch up with the third-grade bluefin tuna.
Moreover, in the western part of the equatorial Pacific, there are more large swordfish. There are actually relatively few large marlin.
This time we caught several marlin weighing several hundred kilograms. It was really like a blind cat caught a dead mouse.
The largest marlins were estimated to weigh six to seven hundred kilograms. When they were sent back to China, each fish cost over one hundred thousand yuan.
The first fishing trip after launching the boat was a perfect start.
Chen Yuan's father and the others are breaking ice and transporting ice slag, and other workers are also busy.
The processing room was not big to begin with, so Chen Yuan and the others stayed inside for a while and then went to the deck.
The front deck, shipside groove, and rope hoisting machine can recycle the dry rope very quickly. If the fish is hung on the hook, cut the line directly, and the fish will fall into the conveyor trough, and then the fish will be sent to the processing room by the conveyor trough. In addition to
Some particularly large fish require the machine to be stopped, and the entire process is completed in one go.
The rope hoist suddenly shut down.
"Old Wang, bring the knife over here."
Another worker responsible for catching the fish brought a knife: "What kind of fish?"
"shark."
Chen Yuan and the others went over to take a look and saw that a great white shark was still alive.
The worker cut the rope with a knife, and the shark flicked its tail and disappeared from the sea.
The machine was started again, and several empty hooks and a fish head were retrieved. The body of the fish was eaten by an unknown fish, followed by another long string of fish.
Bonito, sea wolf, occasionally snapper, and some fish whose names I don’t know.
There are many types of marine fish, and even if you have been fishing for many years, there will still be many fish you don’t recognize.
It's getting late.
Chen Yuan and the others returned to the fishing boat, washed up, and went to bed.
When I woke up, it was already past nine o'clock the next morning.
The fishing boat collected all the fish hooks last night. After the fish were caught in the cabin, everyone took a rest.
At eight o'clock this morning, the first shift of work came out to work. They put the stem of the rope hoisting machine onto the rope hoisting machine and untied the fishhook or branch line buckle on it.
There are also several workers cutting the spurs of short-line fishing hooks.
Short rope fishing hooks and fish hooks can be recycled. The rope that catches a fish is a one-time consumable.
After being proficient in using the hook tying machine, one person can tie 100 fishhooks an hour without much problem.
There are currently 30 people on the nanny. Except for the necessary duty positions, the rest of the people are tying fish hooks. Even if there are 20 people, 100 fish hooks an hour and working eight hours a day, that is 800.
20 people, 16,000.
These things are all consumables.
Nannies are not just called casually, they can really ensure the stable operation of the fishing boat.
In the future, the nanny will not only supply the consumption of Chen Yuan and their fishing boats, but also provide it to Zhao Hai and Gao He.
…
Yang Xun and the others prepared breakfast.
After dinner, I changed shifts with Yang Xun and others.
Chen Yuan sat in the driver's seat and picked up the radio: "Master, has the shift changed?"
"Just changed my shift."
"Is the fish hold full?"
"It's full. Yesterday's two ropes caught more than 200 tons of fish."
"Where are Lao Zhao and Lao Gao?" Chen Yuan asked.
"Their harvest was pretty good. They finished harvesting the fish just after seven o'clock. They also caught a lot of fish, with dozens of tons in total."
"Have Lao Guo and Zhou Jianguo reunited? How many fish are there in Zhou Jianguo's place?"
"It's about a hundred tons. The nanny can go back after loading the fish." Lin Xinhai said: "I feel a little numb at this efficiency."
"This efficiency is normal. How many nautical miles per hour does the nanny cruise at high speed?"
"Festival 17 or 18."
"It's a big head. It takes a month to come and go."
It would take an estimated 11 days to return from a high-speed cruise.
This time cannot be calculated by dividing the distance by the speed. The ship's trajectory must be taken into consideration, and some unexpected situations must also be considered.
Go back to unload, fill up the tank, and run over again...
All things considered, it would take a month to go back and forth.
"One nanny ship is too few and not enough. I feel like we need to buy a few more refrigerated ships..." Lin Xinhai said and laughed.
“How many refrigerated transport ships does Dongjiang Fishery have?”
"I heard that five fish are coming. Their refrigerated transport ship has not arrived yet, and it will take a few days. Our fish catch can only be sent back by ourselves."
Chen Yuan said ‘hmm’.
Lin Xinhai then gave a list of coordinates and said: "We will go to the nanny and Zhou Jianguo's location first. You go out and look for them. If you can still find fish schools, we will continue to find fish schools."
Chen Yuan also gave Lin Xin a few coordinates on the poster: "The last coordinate is outside the lagoon, and there are quite a lot of tuna. The nanny has returned with a full cabin, and we will catch tuna, grouper, and lagoon fish later."
Lin Xinhai thought for a while and said: "If there are schools of fish, we should build fish schools. Once the warehouse is full, we will sell it to Dongjiang Fishery, and the refrigerated transport ship from Dongjiang Fishery will arrive in a few days."
"Okay, let's continue looking for fish schools."
The 80-meter-long big nanny that Dongjiang Fishery followed was a freezing processing ship. It was the same type of fishing boat as the little nanny...
It’s just that the big nanny is bigger and has more advanced equipment.
The freezer processing ship follows the fleet, and its main function is not to transport frozen fish, but to process it. The fish must be eviscerated and then frozen or ultra-low temperature frozen.
Of course, if there are not enough refrigerated transport ships, refrigerated processing ships can also play the role of transporting fish. However, these large ships mainly transport high-value fish, such as tuna.
It would be uneconomical if the freezing processing ship sent a boatload of bonito back.
Chen Yuan's Big Fish is only 37.6 meters long. Although the space layout is good, there is a lot of equipment on board. This results in a relatively small processing room.
Judging from the efficiency of fishing last night, it is too difficult to complete all the fish catch processing on big fish. At most, the high-value fish are processed. The other fish are just bled and kept fresh with ice slag.
These fish are cheap, just waiting to be handed over to the little nanny.
It seems like I have sun again. I had a fever two days ago...
