There is a kind of fish in my country, which is also gorgeous in color and is only a few centimeters in size, the largest being three or four centimeters. However, it is a unique fish in my country. It was common in streams in the past and was also regarded as a kind of small fish.
But now it can’t eat or catch it. Even if it catches it, it will release it. It is "Tangyu". Do you know it?
What kind of fish is Tangyu? Rare
, unique to my country, when it comes to Tangyu, we have to say that some places where Chinese people gather abroad are generally called " Chinatown ". The Tang people are also a name for Chinese people. Tang fish,
, has some connection with this. It is a rare fish unique to my country. It was previously introduced to foreign breeding and attracted much attention for its outstanding appearance, so the name "Tang Fish" was found.
Tang fish is also called many folk in my country. The common are golden silk fish, red-tailed fish, Guangdong fine carp, and Pan's fine carp. Because it was mainly distributed in Guangdong in the past, it was also called Baiyun Mountain fish, Baiyun golden silk fish, etc.
Tang fish is a small freshwater fish of the genus Tang fish family , Tang fish family. This fish generally does not grow big. The males are about 25 mm after adulthood, while the females are larger, that is about 30 mm.
At first glance, Tangyu looks a bit similar to squids, both of which have gorgeous colors, but their differences are still quite big because there are big differences in body shape. Everyone knows that the whip is flat and its body is round like a coin. Although Tang Yu's body is flat on the side, it is longer and its height is about the length of the head.
This fish has a round belly with no abdominal rim. The mouth is small, sub-upper, the kiss is short and round, the eyes are larger, and the length behind the eyes is significantly larger than the length of the kiss. It also has tiny round scales on its body, which will appear bright colors under the sunlight.
Moreover, this fish generally has a brown back and a silvery-white belly, and there is a golden or silvery-blue vertical stripe on the middle side of the body, with several dark brown lines on the top and bottom of the stripe. It is also because of this reason that some places call it "golden silk fish". In addition to this obvious feature,
also has red round spots at the base of its tail shank, and the base of the dorsal fin is also red, so it looks very gorgeous.
In addition, although the male Tang fish is smaller and much slimmer, its fins are larger and the color is brighter, which is also to attract female Tang fish.
This kind of fish generally grows in clear stream environments in mountainous areas. They are brave and lively. They mainly feed on zooplankton and humus. They are small omnivorous fish. The distribution of
in China is mainly concentrated in some mountain streams in the Pearl River Delta. For example, it was more common in Hainan and Guangdong provinces in the past.
Is Tang fish a protective animal? Nowadays, it is not possible to catch or eat
Tang fish is now National Second-Class protected animal , because wild Tang fish are rare, and its protection level in the "Red List of Biodiversity in China - Vertebrate Volume" is in a "extremely dangerous" state.
In the past, this kind of fish was quite common in some mountain streams. After all, it is small and rarely fishes for consumption. Most people regard it as ornamental fish for breeding. But later, the number of these fish became smaller and smaller, and now it is almost extinct in some places. There are many reasons for the sharp decrease in the number of Tang fish. The main reason for is that this fish has extremely high requirements for water quality. In recent years, the water quality environment of Tang fish's living habitat in many places has been polluted to varying degrees.
Although Tang Yu is very small, he is very delicate. It has high requirements for water quality and is suitable for survival in a water quality environment with a pH of about 7.0. At the same time, it is also relatively sensitive to water temperature. The most suitable water temperature is 25 degrees Celsius.
Only when water quality conditions can maintain such standards can Tangyu maintain stable reproduction. However, with the changes and destruction of the living environment around Tangyu in recent years, it has posed a great threat to its survival.
plus the reproductive ability of this fish is also very average. After all, it is very small. The fish can reproduce more than twice in spring and summer. Female parent fish only lays dozens of eggs at a time. and it takes two days to hatch if the water temperature is right, otherwise the hatching rate will be very low.
But Tang Yu seems to be a very stupid fish. The adult Tang Yu actually swallows its eggs. In addition, in recent years, the number of fish such as mosquito-eating fish in many places has increased significantly. They have strong reproductive ability and strong vitality, and they also love to eat eggs of other fish.
has weak survivability and average reproductive ability. In addition, the living environment is polluted, so this has led to a significant reduction in the number of wild Tang fish.
is written later
Don’t think that this kind of fish is small and think it has no value. In fact, as the diversity of in biological , it is also necessary to protect this fish. Even the smallest creatures have the necessity of their existence, not to mention that Tang fish is a freshwater fish unique to our country.
And it is worth mentioning that the ornamental value of Tangyu is also very high. This fish is small in size, but has a gorgeous color, and has a high ornamental value. Moreover, in recent years, major breakthroughs have been made in artificial breeding of Tang fish.
Nowadays, Tangyu has become a national second-class protected animal, but this is also limited to the wild state, and breeding is still available on the market. If you are lucky enough to catch or catch Tang fish in the wild, I hope you will release them in time, because they cannot catch them and eat them, so as not to suffer unnecessary imprisonment.
