Although it looks unremarkable, it is a fish of CYPRINIDAE, Sapindaceae and Triticeae, and a distant relative of carp. If you look at it, it can be seen as a miniature version of herring or grass carp. It looks basically the same, except that its mouth is tilted upward to facilitate foraging.
We often see people catching a lot of things similar to small fry from some drained ponds on the Internet, and most of them are wheat-ear fish. The life span of stickleback is very short, generally only about 3~4 years. Due to the limitation of growth time, it generally does not grow too big, and it will grow to about 10 cm at most. This small fish originated in East Asia, but now it is found in most waters of the country, so it can be said that it has strong vitality.
2. Why are stickleback fish flooding in China?
In fact, this is true not only in China, but also in many countries in the world. The reason for this result is that everyone is deceived by its pure and harmless appearance.
In fact, ear of wheat is an omnivorous fish, which generally feeds on algae, zooplankton and aquatic insects larvae in water, especially mosquito larvae. Therefore, many countries have introduced wheat ear fish to reduce the number of mosquitoes to a certain extent, and wheat ear fish has done this; However, due to its strong adaptability and reproductive ability, it has spread in many countries and become one of the new problems.
The most troublesome thing is that the wheat ear fish also likes to eat all kinds of fish eggs, which makes it a fatal threat to the native fish in many countries. At present, many countries hate wheat-ear fish, but there is no particularly good solution at present, so we can only let it grow and develop.
3. What is the economic value of wheat-ear fish?
Although the wheat ear fish is very small, there is a saying in China that? Mosquitoes are meat no matter how small they are. Therefore, the edible wheat ear fish is naturally targeted by people. In many areas, there are many ways to eat wheat-ear fish, such as frying or making grilled fish, and the price is not cheap, usually 20 to 30 yuan a catty. Although the price is slightly expensive, the meat is really fresh and tender, which has been recognized by more and more people.
There are too many people to eat, so naturally someone has to cultivate them. The menu of wheat-ear fish is very extensive and easy to feed, so it has become an industry to cultivate wheat-ear fish in some places. Because the wheat-ear fish is rich in protein, some places also use the wheat-ear fish as feed, and the sales volume is quite good.
Generally speaking, this can only be attributed to the invasion of wheat ear fish in the wrong place. The last species that was eaten and needed to be farmed was crayfish, and this time it was the turn of the poor wheat ear fish. At present, the reputation of wheat ear fish is not enough, and the number of people who eat it is limited. Once the people of the whole country realize the delicious taste of wheat-ear fish, it is estimated that the demand for breeding may be in short supply.
