Chapter 46: The knowledge of tuna

Of all the tuna, Xiao Peng has only eaten the cheapest bonito. The tuna is ranked according to economic value, the highest is bluefin tuna, followed by bigeye tuna yellowfin tuna albacore bonito. . . . . . Bonito is undoubtedly the lowest.
The tuna is also divided into two lineups, the blue fin lineup and the yellow fin lineup. The bluefin lineup includes Pacific bluefin tuna, Atlantic bluefin tuna, southern bluefin tuna, bigeye tuna, albacore tuna. The yellowfin lineup includes yellowfin tuna, long waist tuna, and blackfin tuna. The price of the bluefin lineup is higher. The economic value of albacore tuna is not as good as yellowfin tuna, not because of its taste, but purely because it is a small tuna, the longest is only one meter long and weighs tens of kilograms.
It looks like a yellowfin tuna. Xiao Peng caught this one more than two meters long and more than 300 catties.
Ye Yuli walked into the kitchen and brought out two large plates, one plate of sushi and one plate of sashimi. The pinkish color made people look appetizing. Xiao Peng picked up a piece of sushi and tasted it. It was refreshing.
"This is frosty'big fat', it can be said to be the most delicious and one of the most expensive positions on tuna." Ye Yuli introduced.
"'Dafei'? Frostfall? How come eating a fish to eat the twenty-four solar terms?" Xiao Peng puzzled.
Ye Yuli hid her mouth and chuckled: "The price of the fish in different parts of the tuna body is different, even the meat of the left and right body, the price is also different. Generally, tuna will be cut along the spine into four fish and two backs. The two belly meats have different prices."
"The left and right prices are different?" Xiao Peng asked.
"Yes, because the tuna is transported with one side facing down, the weight of the fish will squeeze the body on the downward side, and the meat will be easily damaged. Therefore, the upward side is more expensive, and the downward side is more expensive. The price is low."
"The price of belly meat, because of its rich fat, is much higher than that of back meat. Similarly, because of its different location, the price of belly meat is different. The most expensive position of belly meat is the belly meat near the softest fish belly. These meats are called 'Dafei'.'Dafei' is subdivided into snake belly and frost drop. The'big fat' at the front and middle part of the fish's belly is called frost drop'big fat', and the'big fat' at the bottom of the fish's belly is called snake belly. Because of the snake belly' There are obvious tendons in'Dafei', and the price is lower than Frost's'Dafei'."
Xiao Peng was shocked when he heard it, "Is this eating fish? Isn't it too troublesome?"
Ye Yuli smiled: "So when I go to a Japanese restaurant, salmon is the first choice, followed by tuna. The knowledge in tuna is too deep."
Xiao Peng nodded: "Then why is bluefin bigeye tuna so much more expensive than yellowfin tuna?"
"Fat content. The fat content of bluefin tuna can reach 15%, bigeye tuna can reach 8%, and yellowfin tuna is only 2%. In the world of tuna, fat is king. It is also'big fat', The price of yellowfin tuna and bluefin tuna is only one percent of the latter, and the difference is huge! Unfortunately, this is only yellowfin tuna. If it is bluefin tuna, it is delicious. "
"It turned out to be like this." Xiao Peng suddenly realized that he was about to taste the tuna shreds again, but when he lowered his head, he saw only two empty plates.
Looking at Fang Ranran and Yang Meng, the cheeks are full. "Hey, are you two really not keeping us?"
Fang Ranran smiled: "Looking at you guys having a good chat, I thought you didn't want to eat, so I'll help you solve it. Do you refuse to be extravagant."
Yang Meng didn't know what to say. Ye Yuli smiled slightly, walked back to the kitchen, and brought out two plates of sushi and sashimi: "Also, let's eat this way. It would be nice to finish this fish in half a month."
Ye Yuli also took out a plate with two grilled meats on it: "What is this? Roasted rabbit legs?"
"Salt-grilled tuna jaws. Although the muscles are tough, they are rich in flavor and delicious."
"Can you eat your chin?" Xiao Peng scratched his head, how much food was saved by this Japanese.
"Actually, the most commonly eaten part of the people in the Japanese country is called Zhongluo, which is the minced meat near the fishbone. The price is much more reasonable. It is suitable for ordinary people to relieve their greed."
Xiao Peng was helpless: "I didn't think this tuna was so delicious, is it so crazy?"
"For the Japanese people, as for!" Ye Yuli nodded and said, "How do you taste this plate of sashimi?"
Xiao Peng looked at the sashimi coming out from behind Ye Yuli. It looked a little darker in color and looked rather rigid. It tastes a bit more fishy than "big fat", but it can stimulate people's appetite more.
Ye Yuli went on to explain: "This is the meat behind the gills. Because it is less, it is the most expensive place on the tuna. It is slightly more expensive than'big fat'."
"Well, I start to admire the Japanese people, they really did their best to eat fish." Xiao Peng curled his lips.
"Yellowfin tuna is okay. After all, the yield is higher and the fat is lower. Bluefin tuna can make the Japanese people really crazy. In 2013, in the Japanese tuna auction market, a 222 kg bluefin tuna was actually Sold at a high price of 1.8 million U.S. dollars. Even if the bluefin tuna of more than 100 kilograms is not auctioned, it can be sold for millions of Chinese coins."
Xiao Peng was taken aback. How could this be selling fish? It was faster than grabbing a bank. No, you have to get some bluefin tuna in the fishery too!
Yellowfin tuna is there, is bluefin tuna far away?
Fang Ranran went to school after playing on the island for a few days. She had a good time on the island and shot a lot of videos. I was so anxious to go back to school to show off before my classmates.
Fang Ranran left Qianliyan, and the island was much calmer. Xiao Peng was also a lot more relaxed, otherwise Fang Ranran was pestering him every day, the little girl was definitely full of vitality! The kind that doesn't take a break.
And Yang Meng, a guy with muscles in his head, is practicing Wu Qin Xi hard every day after putting feed in the fishery. He doesn’t know when he will fix the fitness equipment on the beach and practice hard every day.
It seems that losing to Xiao Peng really hit him hard.
Xiao Peng understood him too. The two had known each other for so many years, Yang Meng had been protecting Xiao Peng, and suddenly realized that Xiao Peng was better than himself, which was a big blow to Yang Meng.
Feeling that what I have done for so many years is useless? Xiao Peng felt a little apologetic for being uncomfortable with anyone else.
Xiao Peng often secretly input witch power to him. Now Yang Meng's physical fitness is very different from before.
Ye Yuli is now the steward of the island, and she takes care of everything on the island in an orderly manner.
In comparison, Xiao Peng is an idler.
Except for a whim and took out the golden nanmu in the warehouse to carve a tea table, he had nothing to do every day.
The teapot found in the submarine has now become Xiao Peng's favorite. Every day, Xiao Peng holds the teapot and lays in the hot spring and smokes his pipe.
In fact, this is not to blame Xiao Peng, Xiao Peng seems to do nothing every day, in fact, he is always observing the conditions of the seabed fishery.
The development of fisheries is very rapid. The released macroalgae have now grown to more than ten meters long. This attracts a lot of marine life here.
What made Xiao Peng even more happy was that the bigeye tuna and yellowfin tuna that were driven by the dog eggs had settled in the fishery.
This is good news. You must know that tuna is a cruising fish that travels around the world with food. So far, only a very small number of people have the means to cultivate tuna artificially.
The Japanese people have been committed to tuna farming technology for decades. Today, they have achieved success. They are divided into three methods: short-term breeding, breeding, and complete breeding.
Short-term stocking is a way to grow up the tuna quickly after several months of rearing the small tuna that has been caught in the tens of kilograms.
Breeding is to raise the newly born wild tuna fry in captivity for two or three years before selling them.
Complete breeding is the whole process from hatching fish eggs to breeding. All are done manually. The difference between this method and the first two is that he no longer breeds wild tuna fry. It is of great significance for the protection of wild bluefin tuna resources.
Of course, these three breeding methods have big problems. That is, the cultivated tuna are all small. Because tuna needs to maintain a high-speed movement to ensure that there is enough oxygen to flow through the gills, otherwise it will suffocate and die. So tuna needs a lot of food and living space. Artificially farmed tuna is limited to these two, so the body is small. The same bluefin tuna fry can grow up to three meters in length in the wild, and it is good to grow up to one and a half meters in captivity.
And this also requires God’s blessing, for these three years, do not have any accidents, so that they can live to three years.
There is a huge risk in this, and it is definitely a money-burning project. If there is no return for a few years, if there is a small mistake, it will lose money. But even so, there are still many Japanese marine scientists who have joined in this scientific research project.
So, the Japanese people really had enough to eat tuna.
But these situations encountered by their scientific research species did not exist in Qianliyan Fishery.
Xiao Peng put a large amount of Enteromorpha feed in the Qianliyan fishery. These Enteromorpha feeds have become food such as small fish schools in the fishery.
This promotes the growth of fish schools and also changes their meat quality.
And they have become the best food for tuna. The reason why tuna cruises around is because of the high requirements for sea water and food quality. For tuna, the food here is unprecedented.
The nutrient-rich feces of tuna become food for plankton and macroalgae, and then one after another, the entire fishery constitutes a huge biological chain.
In such a living environment, let them go, they don’t go--these fish are not stupid, right? Where can there be better living space?
