Recently, Chongqing media reported that an abandoned reservoir in Nan 'an District of Chongqing was gradually being built.
After drying up, hundreds of wild betta fish living in the reservoir are facing difficulties in survival. It is said that this kind of fish
It's rare in the local wild. Some people abroad pay a high price for it, but it's not taken seriously at home. Two netizens
To this end, the "Save the Wild Bettas in the South Bank" campaign was launched, hoping to find a new one for these wild bettas.

It is probably the first time that many people have heard of the name "fighting fish with fork tail", and they think it is something rare.
Rare fish, after seeing the photos, suddenly realized that this is not our Bodhisattva fish, the old man who burns the fire,
Three boring women, frank and boring, broad-skinned, mother-in-law fish, lion-haired fish, towel flower, pengpi cymbal, flower orchid fish,
Strange brake woman, Kyubi no Youko Niang ... (it seems that every place has its own name), our pond there,
Paddy fields and ditches are everywhere. I caught them and played with them when I was a child. Laughed at the news as speculation.
As a result, a netizen also left a message sarcastically saying: "What a fuss, we have a lot of family, do you want to go?"
Where can we buy it? A dime a piece will ruin you. "
The netizens who left these messages came from Guangdong, Guangxi, Fujian, Jiangxi, Hong Kong and other places. In China
In South China, fighting fish with fork tail is very common indeed. This is a small fish (about 6 ~ 8 in length)
Cm), the meat is terrible, and it is just for children to keep and play, a little boy living in towns and villages.
Most children have caught and raised it, which constitutes an interesting part of childhood memory. The reason why it is so
Popular, one is easy to catch in the wild, and there is no need to spend money to buy it; Second, it is easy to raise, using a can.
Bottles can be kept, flies, mosquitoes, earthworms, shrimps and small fish will eat everything, and they will be hungry for a month.
Can't die; Third, he is good-looking, and the male fish has red and blue stripes, which makes him more gorgeous.
It can be regarded as the most beautiful wild fish in South China. Fourth, the male fish is extremely aggressive, putting two male fish in
Together, we will fight to the death, so we should raise them separately. Put a mirror in front of the fish tank, and the male fish also
Will keep attacking his own shadow. The common name of this fish in Minnan and Taiwan Province is "San".
Spot ",but our children there also call it" playing tin ",which is probably to describe its aggressive nature.
Grid.
Because of these reasons, betta has become the second species introduced to the west after goldfish.
China ornamental fish. Swedish Linnaeus, the father of modern taxonomy, published his masterpiece "Since" in 1758.
However, it was described scientifically for the first time in the 10 edition of the system, and the Latin that is still in use today was determined.
Scientific name. Linnaeus may have just seen a specimen. It was first introduced to the west in 1869, France.
The consulate in Ningbo ordered a French official to bring 100 betta back to China. Travel long distances
After that, 22 of them survived, of which 17 was given to the famous Paris breeder Carponier.
He succeeded in breeding. This is the first kind of freshwater tropical fish that has been farmed artificially.
Later, it became a very popular ornamental fish in the west, and it has a beautiful name-"Paradise Fish".
Although many people have raised this kind of fish, not many people try to breed it, so there is no such thing.
I noticed that it has very strange reproductive behavior. When the weather gets warmer in spring, the male fish will swim to the surface.
Inhale, then sink into the water and spit mucus while blowing, forming countless small bubbles and sticking together.
Floating on the water. This is the nest prepared by the male fish for the next generation. After the nest is built, the male fish goes to the female fish.
Demonstrations, dancing, courtship, if the female fish refuses her courtship, or the female fish is not mature and old.
The angry male fish will attack her and even kill her. If the female fish accepts the courtship, the male fish will
Entangle her, turn her body over, lay eggs with her abdomen up, and the male fish lies under the female fish.
When the fertilized egg sinks, the male fish will hold it in his mouth and stick the egg to the nest. Female fish production
After the eggs are finished, the male fish will drive them away, and he will keep the nest and drive away anyone who tries to get close.
Fish. After about a day or two, the young fish hatched and temporarily lived in the nest. The male fish continues.
Guard, if a young fish falls, he will drag it back to the nest. After another three days, the young fish can
Free to move, then the male fish pulled them out of the nest.
Because of this nesting habit, the betta fish needs a calm water surface and can only live in ponds.
Reservoirs, ditches, rice fields and other still and stagnant water. Besides, there is nothing critical about the environment,
It can survive in water with low dissolved oxygen, because the betta has two sets of respiratory organs, except gills.
Absorbing oxygen in the water, there is also a special auxiliary respiratory organ-the labyrinth, on the back of the gill.
Capillaries on the surface can inhale oxygen in the air when they come into contact with air. So fork-tailed fighting fish often
Quickly put your head out of the water to breathe air, sometimes moving too fast, even jumping out of the water, jumping
Outside the fish tank, people thought it was suicide.
There are so many bettas in the wild and their vitality is so tenacious that it seems that they will not be destroyed.
The disaster. However, in 1990, Taiwan Province Tsinghua University conducted an investigation and found that it was originally in Taiwan Province.
The widespread fork-tailed betta (Taiwan Province called the goby) is due to the loss of habitat, pesticides and labor.
Industry pollution and other reasons have actually been on the verge of extinction, prompting the Taiwan Province Agriculture Committee to announce on August 3 1 day of that year that it would
It is included in the rare and precious conservation wild animals to be protected, and the rehabilitation plan is implemented. Recent reasons
Yu noticed that wild betta fish especially like to eat jaguars (according to statistics, one tail can eat more than 300 fish a day)
It is helpful to kill mosquitoes, and some institutions in Taiwan Province systematically organize primary school students to breed and stock.
Observe this "environmental fish". Childhood play has been given a new meaning.
Those factors that lead to the endangered betta in Taiwan Province also exist in the mainland, and they are getting worse. continent
Now some people have begun to pay attention to the protection of this beautiful, interesting and beneficial small fish, which is actually worth it.
Encouraging.
