How much is a catty of Taishan red scale fish?

Red-scale fish in Mount Tai, the value of raising small fish is nearly 1,000 yuan. Between Mount Tai, the head of the Five Mountains, there is a kind of precious fish called red scale fish. Known as the spirit of Mount Tai. It is small in size, agile in water, and can only live in the streams of Mount Tai, so it is also called Mount Tai Elf. Red scale fish is a special food of Mount Tai. At present, the number of wild red scale fish in Taishan is less than 1000, which is listed as a protected species. In order to meet the demand of the consumer market, many farms in Taishan have begun to cultivate red scale fish artificially. Red scale fish grows slowly and has tender meat, which is deeply loved by consumers. In a restaurant, a 20-cm-long red scale fish can buy nearly 1,000 yuan. This has brought many benefits to farmers.

Mount Tai, the head of the majestic Five Mountains.

Blair: I cut my hand.

There are mysterious and rare fish.

Blair: Alas!

Wang Changyin: Yes. It is the incarnation of the dragon.

Why has it lived in Mount Tai for 30 million years?

Researcher Liu, Fisheries Department, Tai 'an Water Resources and Fisheries Bureau, Tai 'an City, Shandong Province: In this environment with an altitude of 270-800 meters, Taishan Spring must survive.

What makes it so expensive?

Su Yanyou, a professor at Taishan Medical College: DHA content is 40 times that of sharks.

Blair: Today I came to Mount Tai, the head of the Five Mountains. Speaking of Mount Tai, it is magnificent and picturesque. But the purpose of my coming here today is not to enjoy the scenery. This time, I will follow Mr. Wang to find the mysterious species unique to Mount Tai. It is said that a few years ago, every time I climbed a mountain, I could find it at most once.

Wang Changyin: Yes, it's not easy to see.

Brother Wang Changyin is the head of Taohuayuan Scenic Spot in Taishan Mountain. The mysterious species he mentioned is a kind of fish that can only survive in Taishan Stream in Tai 'an City, Shandong Province, China.

But most of these fish live in the deep mountains of Mount Tai, far from the scenic spots, so if you want to find them, you must go deep into the mountains.

This is a great challenge for our reporter Betty Wong.

Blair: My hand hurts.

Although Betty Wong cut his hand, he didn't flinch. Where is the fish we are looking for?

Wang Changyin: I saw it in this pond last year, but I haven't found it several times this year.

After climbing the mountain road for more than an hour, I saw this stream, which was crystal clear but also very fast. So can Betty Wong be lucky enough to see this mysterious fish in Mount Tai today?

Blair: Oh, there are two small fish. so this is it？

Wang Changyin: Yes, yes, that's right.

This is too small. If you don't look carefully, you won't notice them.

After such great efforts, our reporter Betty Wong was a little disappointed to see such a small fish.

Blair: Then I think it is no different from ordinary small fish.

Wang Changyin: It makes no difference if you don't look carefully.

Blair: What kind of fish is this?

Wang Changyin: This is a red scale fish.

It turns out that its name is red scale fish, which is a small fish of Tusnout unique to Mount Tai. It is said that the red scale fish has lived in the streams of Mount Tai since its formation and has evolved for 30 million years. Because of their small size, they are very flexible in water. Our cameraman followed them several times and almost lost the target. Brother Wang Changyin told us that red scale fish is sensitive and suspicious by nature. When they felt that we were on the shore, they quickly swam to the cracks in the rocks deep in the stream to escape. Therefore, it is difficult to observe them up close.

Blair: Brother, can I catch one and have a look?

Wang Changyin: No, wild red scale fish are protected locally. There are farmed ones ahead. If you want to see it, we can have a look.

In order to get a close look at this mysterious red scale fish, Betty Wong decided to explore the local farm.

Blair: Wow, there are so many fish here. I think there are almost hundreds. Compared with what we tried our best to find on the mountain just now, I'm really not used to seeing so many fish. Excuse me, big brother, are these fish red scales?

Farmer Tong Lihua: Yes. This is a farmed red scale fish.

Blair: Can you catch one for me?

Tong Lihua: Yes, it's not easy to catch anyway. I'll try.

Blair: Is there?

Tong Lihua: No.

There are many here, and they have run away again.

Brother Tong Lihua, who has five years' experience in red scale fish farming, told us that although these red scale fish are farmed artificially, they are also very flexible to swim and it is not easy to catch them with their hands, even in such a small pond.

Tong Lihua: Why don't you come down and we can cooperate.

Blair: Well, in order to catch this red scale fish, I'm going to change my pants and cooperate with my big brother.

Blair: I can't believe we can't even catch a fish in such a small pond. Let's go over there and get stuck in that place. There are so many fish! I can't catch this at all. I feel the fish slipping out of my hand.

Sure enough, as Brother Tong said, even if two people join hands, it is not so easy to catch these agile little guys with their bare hands. Looks like we're gonna have to fuck those guys

Blair: Wow, I finally caught one. It's struggling, it's too slippery! This fish is really slippery, but the first feeling when you get it is that the fish's body is particularly soft. I didn't dare to squeeze it with all my strength, and the fish's mouth was square, its head was slightly raised and bent, and then its whole body was golden yellow, its fins and tail were all golden yellow, but there was a little red at the back of its tail, which was a feature only found in red scale fish.

Tong Lihua: That's right.

In order to observe them more clearly, we put them in a glass jar. Under the irradiation of light, their scales are shining with golden light, which is very dazzling. Speaking of which, one thing has to arouse our curiosity. Since the red scale is gold scale instead of red, where did the name of the red scale come from?

Researcher Liu, Fisheries Department, Tai 'an Water Resources and Fisheries Bureau, Tai 'an City, Shandong Province: It is said to be a dragon with a square mouth and no horns, and it is one of the nine sons of the dragon.

It turns out that the real name of the red scale fish is Chilin fish, which is said to be the embodiment of the ninth son "Kiss" of the dragon. Therefore, the name of red scale fish is not determined by the color of its scales, but people misunderstand the word red scale, but even so, locals are used to calling it "red scale fish". Speaking of red scale fish, people say that it is mysterious not only because of legend, but because it has a special skill that most fish don't have.

Blair: It is said that this red scale fish has another amazing feature, that is, it will change color according to the change of environment. Look at this light pond. This fish is brown, and the fish I just fished out of a dark pond is black. Let's put this fish in and see what happens to its color. You see, the colors of these two fish are completely different. It's less than 20 seconds now, and the color of this snakehead has gradually faded. I don't think I can tell which fish I just put in. It's amazing.

It is understood that this color-changing characteristic of red scale fish is an important means for them to protect themselves in the natural environment. In addition, the red scale fish has another feature, that is, it has high requirements for the living environment.

Researcher Liu, Fisheries Department, Tai 'an Water Resources and Fisheries Bureau, Tai 'an City, Shandong Province: It is required to live at an altitude of 270-800 meters, and it must be Taishan Spring to live. Why do you say Taishan spring water is because it requires high dissolved oxygen in water, which is above 5 mg/L.

It turns out that red scale fish can only live at an altitude of 270-800 meters above sea level in Mount Tai, and the living waters must be Taishan mountain spring water, so the farms of red scale fish are built on the mountains of Mount Tai.

Blair: I'm in the upper reaches of this farm now. The water flowing down from this rock wall is the mountain spring of Mount Tai, so the red scale fish at the foot of the mountain are cultivated with this water. Then there is the saying that the red scale fish does not go down the mountain, which has a lot to do with its water quality. The water feels cold and cold, and it is so sweet. No, I can't bathe in this mountain spring here or the whole person will drown.

The spring water in Mount Tai is cool and sweet, and the excellent living environment breeds a unique and rare species, red scale fish. In addition, the temperature of the living waters of red scale fish must be between 4 and 28 degrees Celsius. In spring and summer, the temperature of mountain spring water is about 25 degrees Celsius, and in autumn and winter, the water temperature is low, the water fluidity of farms is poor, and the water surface will freeze, so farmers will also build greenhouses to keep the fish warm. It seems that in order to make red scale fish thrive, farmers really take great pains.

Blair: I'm in this pool now, and my big brother told me that this is the most special pool, because the fish in this pool is a little bigger, about 15 cm. Why are the fish in this pond a little big?

Tong Lihua: Because it is full of parent fish.

Oh, the hatched fish, right?

Tong Lihua: Yes.

Blair: Can we catch one here and have a look? See what this big fish looks like.

Tong Lihua: OK.

Blair: Wow, this fish is really big. The overall appearance characteristics of this larger red scale fish are more obvious. The color of the whole picture, this yellow is also obvious. It's really beautiful in the sun. Let's measure the length of this fish. 26 centimeters. Although it is relatively small for ordinary fish, it is quite large for red scale fish.

Tong Lihua: Fish is king.

Blair: Fish King, right?

Tong Lihua: Yes.

Blair: Wow, we caught the fish king. How old is this fish?

Tong Lihua: Fourteen or fifteen years old.

Blair: How much is it?

Tong Lihua: About fourteen or fifteen years.

Blair: Fourteen years or fifteen years?

Tong Lihua: Yes.

Blair: After all these years, it can only grow so big, right?

Tong Lihua: Yes.

In the case of artificial breeding, it takes two years for red scale fish to grow to more than 8 cm before it can be put on the market. Although they are not big and grow slowly, their food requirements are not low. In a pond with a density of 1000 fish, not only about 4 Liang of feed is fed every day. Three months before the fish went on the market, a secret weapon was specially prepared for them.

Farmer: Look, Blair, this is our secret weapon.

Blair: Secret weapon?

Farmer: Yes.

Blair: I just feel stupid. What's in this?

Farmer: This is live bait.

Researcher Liu, Fisheries Department, Tai 'an Water Resources and Fisheries Bureau, Tai 'an City, Shandong Province: By feeding biological bait for two months, the conditions of imitating wild can basically be achieved, and the quality of red scale fish has been greatly improved.

In addition to feeding fish with proportional feed, live bait should be supplemented. It seems that the food of these fish is really good. It is understood that the feed cost required for a fish to leave the pond for two years is around 5 yuan. So where are these red scale fish sold?

Tong Lihua: sold to restaurants or hotels, mainly for food.

Li, Director of Water Resources and Fisheries Bureau of Tai 'an City, Shandong Province: Red scale fish is a specialty of Tai 'an.

When it comes to the authentic Shandong cuisine of red scale fish, we have to mention the local chef Cheng Xiangshou. Many people come to Taian to taste his red scale fish dishes. Among them, the most popular is dry fried red scale fish.

Blair: The dish in front of me is called dry fried red scale fish, which is the most distinctive local practice of red scale fish in Tai 'an. Let's try it quickly. This meat is really tender. I haven't chewed it yet. I feel it will melt in my mouth. Besides, this meat tastes rich and delicious. Then I didn't get any thorns when I ate this fish. Even if there are thorns, they are soft and can be eaten together. It's delicious. In fact, when food is made of a good ingredient, we often feel its texture first. When its texture and delicacy can be combined, it really completes a very beautiful experience and feeling in our taste buds. If you want to taste this dish, you must return to its essence. (www.nczfj.com) I don't think you will be disappointed when you come to the local area to taste the most distinctive local practices.

Red scale fish is delicious and has been a tribute of the imperial court since ancient times. So what's so special about the nutrition of red scale fish?

Su Yanyou, a professor at Taishan Medical College: DHA in unsaturated fatty acids is the most important cost in the nutrients of red scale fish. DHA is rare in general freshwater fish, and its content is 40 times that of big sharks.

According to Taishan medical records, red scale fish is warm, sweet and clear, and has the effects of nourishing brain and intelligence, nourishing face and invigorating qi. Although the red scales are not large, they are sold locally in Tai 'an, and it is still necessary for 68 yuan to eat such small ones. Although it is expensive, many people come to taste this delicious dish specially, because it is a precious fish unique to Mount Tai.

Consumer: The meat is tender and tastes good.

Consumer: There is no fishy smell.

Consumer: The meat is tender and the thorns can be eaten. There is a slippery feeling in my mouth.

Consumer: Only 68 yuan, and all ten of us are from 680 yuan. The price is a bit expensive, so it would be better to make it cheaper.

With the vigorous development of red scale fish industry in Taishan, some enterprises also aim at business opportunities and make red scale fish into ready-to-eat products, so that people all over the country can taste the delicious food from Taishan.

Consumer: I want to travel to Mount Tai. I saw this red scale fish clearly. I bought it for my family to taste.

Consumer: Buy a box. Try it first.

Consumer: Everyone in Tai 'an knows Taishan red scale fish, but I have never heard of any ready-to-eat fish. I saw some ready-to-eat fish today, so I bought two boxes to try first.

Zhang Xindong, Mayor of Jin Linlin, Tai 'an City, Shandong Province: At present, we have developed instant red scale fish and red scale fish wine.

Now, through the protection of the wild red scale fish population by relevant departments, the number of wild red scale fish in Taishan has reached nearly 10,000, and through artificial breeding, red scale fish have also swam to the dining table of the people and become a local business card in Tai 'an.

Red scale fish farmers in Taian City, Shandong Province have Weidong farmers: I have 70,000 to 80,000 red scale fish here, with an annual income of about 300,000.

Wang Canliang, Director of Zhi Lin Fish Farm in Tai 'an City, Shandong Province: Every year, the number of fish coming out of the pond can reach about100000, and each fish is sold to 20 yuan at the market price, with a sales income of about 2 million yuan.

Li, Director of the Water Resources and Fisheries Bureau of Tai 'an City, Shandong Province: There are 130 red scale fish farms around Tai 'an area, with an annual output of1000000, which drives the output value of surrounding areas, including catering, tourism and related output value of more than one billion yuan.
