Speaking of fish, it is estimated that many people know more or less, and friends who like fish are not in the minority.
Even a few years old dolls will be quite interested in fish, especially the rural dolls who used to live in the countryside, and they are very fond of fish. At that time, there were still many fish in the countryside, and there were many fish in large and small puddles.
The most of them is a small fish the length of a thumb, which is particularly abundant in fertile rice fields, and dozens of them can be grasped at once with tools, and it is possible to catch hundreds or thousands of larger tools at once.
This fish is known as the wheat ear fish, it is not unique to the mainland, and it is not native to the continent, it is an exotic fish, and now it is "wanted" by countries around the world, it is a famous invasive alien species, which seriously endangers European and American countries, and is the number one "wanted criminal" in European and American countries!
Wheat ear fish has been popular in many countries as early as the last century, and has now invaded the world, 32 of which are particularly serious, many native fish are endangered due to the invasion of wheat ear fish, seriously affecting the local ecosystem.
Can a small ear of wheat endanger local fish?
Wheat ear fish is not large, generally about 10 cm, smaller only a few centimeters, this kind of unassuming fish, not simply vegetarian, more often, they are eating "meat"!
When the wheat ear fish is young, it mainly feeds on planktonic algae or aquatic animals, but after growing to 5 cm, it mainly begins to catch mosquito larvae or aquatic insects, and also eats the eggs of other fish.
It is precisely because it eats the fish of other fish that other fish are in danger of extinction in this water, and the wheat ear fish can spawn 3 times a year, and the number is large, and the reproductive ability is particularly strong.
A powerful "legion" of wheat ear fish can eat the eggs of most other fish, causing other fish to reproduce badly, and eventually leading to extinction.
Taking the mainland Yunnan as an example, around the 1960s, people introduced fish to plateau lakes such as Erhai, Fuxian Lake, Dianchi Lake, Lugu Lake, etc., but these fish were mixed with small fish such as wheat ear fish, resulting in heavy losses of local indigenous fish.
After 10 years, Yunnan native fish Erhai carp, Yunnan split-bellied fish, gray split-bellied fish, Dali carp, etc. are almost extinct, of which yunnan Dali split-bellied fish production in 1973 was about 15 tons, about 2 years only 0.5 tons, only a few kilograms after 3 years...
Therefore, when fish are introduced, small fish such as wheat ear fish are mixed in, which has a huge impact on the ecological environment. Of course, there is also an unshirkable responsibility for the large number of fishing, the big fish are caught, and the eggs are eaten by the wheat ear fish, resulting in inability to replenish and loss of balance. However, compared with European and American countries, the loss of indigenous fish in Yunnan is not very large.
The "hardest hit area" of wheat ear fish in Europe?
It is not only Yunnan that is disturbed by wheat ear fish, but it is not only the presence of wheat ear fish in many parts of the mainland, but compared to the United States, India, Russia, Vietnam, Myanmar, Australia and European countries, these are nothing.
The wheat ear fish is not large, and it has spread to various countries as an ornamental fish, or when importing other fish fry, and has invaded 32 countries and regions. Because of its particularly strong reproductive ability, it soon developed.
In addition to eating fish eggs, wheat ear fish also transmit some fish pathogens, which leads to infection of other fish and eventual extinction, such as the small red shoot fish in France.
In addition to affecting fish in natural waters, wheat ear fish will also cause harm to farmed fish, and the pathogenic bacteria and parasites it is infected in natural waters may cause aquaculture to be "completely destroyed".
More importantly, European and American countries do not like to eat freshwater fish, especially small fish such as wheat ear fish, there are many thorns, they can not cook at all, can only allow the wheat ear fish to flood, and eventually become their "heart trouble"!
Wheat ear fish "conquered" the magic weapon of Europe and the United States
Wheat ear fish used to be abundant on the mainland, especially those fertile rice fields, which basically had its presence. But in the cool and clean water, there is very little of its presence. After years of sewage treatment, ecological environment treatment, etc., the water quality on the mainland has become better, and the wheat ear fish has also become less.
The main reason is that today's big fish (most of the artificially farmed) are not delicious, and small fish such as wheat ear fish are more delicious, fried, and the taste is particularly fragrant. In the market, the wheat ear fish can also sell for tens of yuan a catty, and it is difficult to grow on a large scale in the mainland. But also pay attention to precautions, do not be careless.
But in Europe and the United States and other countries, wheat ear fish no one eats, and they lay a large amount of eggs, do not look at it small, a once can lay thousands of eggs, can lay 3 times a year, the key is that they themselves are particularly numerous.
Wheat ear fish eat the eggs of other fish, but they are particularly protective of their own fish eggs and will "escort" their offspring, including the juvenile stage. This is the rhythm of allowing their offspring to multiply widely, so that other fish "cut off their grandchildren" (wheat ear fish will eat the eggs of other fish).
Super reproductive ability, eating the eggs of other fish, super high survivability and adaptability to waters, is the magic weapon for wheat ear fish to conquer the world. It thrives in environments where other fish can't survive, and in dirty and messy waters.
Therefore, although the current breeding of wheat ear fish on the mainland is not particularly large, it is also necessary to pay attention to fishing, so as not to flood them, fortunately, the wheat ear fish taste good, if you let go of fishing, it will soon be reduced.
However, in some countries in Europe and the United States, the wheat ear fish has become a major problem for them, and they cannot take effective measures to prevent it, and they can no longer hold their positions! Wheat ear fish pose a serious threat to them, and if left untreated, it is estimated that after many years, only wheat ear fish will remain in those natural waters.
Conclusion
Although the wheat ear fish is small, it is indeed a globally recognized invasive alien species and is very harmful. If you can catch or catch a wheat ear fish, remember not to release it.
If the number is relatively large, you can also take it home to eat, it is also very worth eating, the meat is tender, the taste is also very delicious, the soup is very good, the frying is better, the rice is delicious, and the wine is more delicious.
Although the wheat ear fish has thorns, but the intermuscular spines are relatively small, and the thorns are relatively soft, fried, even the thorns with meat, even the bones can be eaten, and the bones are very crispy, especially delicious.
