Foreword:
Introduction: bamboo shoot shell fish , often regarded as native fish, but it is actually a "foreign household", and it will change color for hundreds of dollars per kilogram
Bamboo shoots are often seen in many vegetable markets in China.
Friends who know spring bamboo shoots know that spring bamboo shoots are different from winter bamboo shoots . There are many layers of thick bamboo shoots on the outside. This should be removed, otherwise it will affect the taste.
In some aquatic markets in the south, occasionally you will see an ugly fish that looks like a bamboo shoot shell, which is called "bamboo shell fish".
In China, many people don't know the bamboo shoot fish, and some people often regard it as a native fish. In fact, it is an invasive species and a delicious "foreigner".
When it was expensive in the market, bamboo shell fish sold for hundreds of yuan per pound.
Bamboo shell fish: delicious "foreigners"
The reason why many people often regard it as a native fish is because this fish is indeed very similar to a native fish in my country.
But bamboo shellfish is a genuine foreigner. It is native to Southeast Asian countries and the Australian mainland.
This fish has a big head and a small tail, and its body is very sturdy. It looks like a bamboo shoot, especially when it is caught, it will open its mouth, hold its head up, and open its two fins, like this. Extremely bamboo shoots, hence the name.
The bamboo shoot fish cultured in my country comes from Thailand, which was introduced in the 1980s, and is mainly cultivated in Guangzhou, Fujian and other regions with a small amount of commercial fish.
Of course,There is another reason why the bamboo shoot fish is mistaken for the native fish, that is, the existence of this fish is not strong, the popularity is not high, and the harm is not as great as the invasive animals such as crayfish, bullfrog, scavenger, so Many people ignore its existence.
Ugly, but also a ferocious fish
Bamboo shellfish is inconspicuous, even a little ugly. Many people are shocked by its "face value" when they see it for the first time.
In fact, bamboo shellfish is not only ugly, but also a ferocious fish.
The swimming ability of this fish is not strong, and it is often found on the bottom of rivers, lakes, ponds and other waters, and often inhabits sand and gravel crevices, caves and debris along the shore.
But the bamboo shoot fish is a kind of carnivorous fish, it is mainly in the fry stage of rotifers, cladocerans, copepods and benthic aquatic insects larvae and annelids_ span5span feeds, and when it grows up, it mainly preys on various small fish, shrimps, crustaceans, mollusks, aquatic insects and larvae in the water.
Just because this fish has sharp teeth in its mouth, and unlike most other fish, the bamboo shell fish not only has a mouth full of teeth, but also has a tongue, which provides it with food for prey. A nice convenience.
What's more worth mentioning is that the bamboo shell fish also has a strong ability to resist hunger. When they eat a full meal, they can not eat for a few days. Maybe this is also related to the fact that they don't like to be transported, and they are quiet when they are full. Stay still under the water, motionless.
In addition, the bamboo shoot fish has another ability, that is, it will change color. When caught, it will turn grey-black if it is on the surface for more than a minute.
and put it in the water, the color will gradually turn white, and the body will be grayish white.
In fact, there is still a big difference between the bamboo shoot fish and the native gobies in my country. Like the native gobies, they are generally small.The maximum is difficult to exceed half a catty.
But the bamboo shell fish is very big, and in the right environment, the largest can grow to more than 20 pounds.
High economic value, when it is expensive, it is hundreds of yuan per catty
Since it has been introduced in China, it must be because of its economic value, and it is also regarded as a special species of fish for promotion and breeding.
In many aquatic markets in the south, you can only buy this kind of fish with good luck, and the price is relatively expensive. When it is expensive, it costs hundreds of yuan per pound, even if it is usually 60 or 70 yuan per pound.
The reason why the price of bamboo shoot shell fish is so much higher than that of and the four major fish is because there are not many farmers who breed it, and secondly, the meat of this fish is very delicious, very nutritious, and has a high food value.
bamboo shoot shell fish contains more than 5 times the protein than milk, and it contains almost 18 kinds of amino acids that the human body needs, which has excellent health care effects, especially suitable for the elderly and children. It has edible value such as nourishing qi, nourishing deficiency, beautifying skin, improving memory and so on.
It is with these advantages that in some hotels in Guangdong a few years ago, bamboo shoots were sold for several hundred yuan per pound.
At that time, some farmers raised bamboo shell fish and achieved the goal of making 10 million yuan a year, just because of its large market demand and high profits, at the peak it was as high as 70%.
Some people may wonder, since it is an invasive species, why is the bamboo shell fish not flooding in the country?
In fact, bamboo shellfish has been introduced into China for thirty or forty years, but it is rare in the wild. There are three main reasons. The first is that it has natural enemies, such as carnivorous fish, and it is too delicious. , can not escape the fate of being caught.
The second is the lack of food. After all, bamboo shellfish is a carnivorous fish. If there is not enough food, it will be difficult to flood.
last bit,That is, because its meat is delicious and expensive, it has been artificially overfished in the wild. It can be said that if there was no artificial breeding, the bamboo shellfish in the wild would have long since become extinct.
Concluding remarks
People who don't know them will regard bamboo shoots as native fish, and even think that gobies have mutated. In fact, they are another kind of goby, a "foreigner" from Southeast Asia.
Unlike other invasive species, however, the bamboo shellfish is a delicious invasive species. It can be sold for hundreds of yuan a pound in the market, which is the best proof.
But we should also remind everyone that there are risks in farming. Don't blindly follow the trend when you see that the price of bamboo shoots is high and the profits of farming are also high. This kind of fish has a high threshold for breeding and is technically difficult, so it should not be farmed blindly!
