Everyone is familiar with the silver carp, this fish head is relatively large, and the fish head of the fish is relatively few, the meat is tender, it is very good to make chopped pepper fish head, but the following silver carp is very special, because of the duck beak.
Blogger @皖R posted a video on September 21 with the caption: "The first time I saw this fish mouth". So what's so special about the mouth of a silver carp? Here's a GIF of the video, and you can see how strange these silver carp are.
In the video, when the blogger was fishing in his own fish pond, he caught a few silver carp, but what he didn't expect was that the mouths of these silver carp were very strange, and I saw that the mouths of these silver carp were very wide, especially the lower lip was like a growth.
It is very different from our common silver carp, and the body color of these silver carp is also relatively dark, what is going on? After this video was released, many netizens replied.
Some netizens replied: "This kind of duckhead carp raised a lot of fish ponds in front of my house when I was a child, why can't I see it now." It seems that this kind of broad-mouthed tarpon is not an exception, and the fish pond in front of this netizen's house used to have a broad-mouthed tarpon.
Judging from the video, this kind of wide-mouthed tarpon is the same size as the normal tarpon, and the body is not much different, but the mouth is wider and the color is black, which are two differences.
Some netizens replied: "What disease is this caused by"? It is true that it is not all smooth sailing for fish to survive in the water, and they need to face not only the attacks of various predators, but also various diseases.
For example, ichthyosis, the scales on the surface of the fish body are like exploding; Anchorhead eel, anchorhead eel is a parasite that parasitizes the body surface of fish; Noodle worms, noodle worms are parasites that live in the stomach and intestines of fish; rotten gills, slow festering of the gills and so on.
If the density of fish farmed in the water area is relatively large, the fish are easy to get sick, sometimes it is the bacterial infection caused by the poor water quality, and sometimes it is the parasitic infection, so netizens wonder if it is normal caused by disease, so is it really caused by disease? Not really.
Some netizens replied: "Discover new species"? It is not a new species, but caused by the living environment, mainly in two aspects, the first is hypoxia, and the second is that there is too much cover on the surface of the fish pond, such as lotus leaves and duckweed, etc., these fish are likely to be caused by lack of oxygen.
Those who have lived in the countryside know that there are ponds in the rural villages, these ponds are not naturally formed, some are taken from the soil to burn bricks, etc., digging a big pit, and some are why the water is collected and drained, and the deep pits dug in the village, these deep pits slowly become ponds.
This is how the four ponds in my village were formed, and in the last century these four deep pits were connected by drainage canals to the small river outside the village. Whenever it rains, the water in the pond is discharged into the river, and the fish in the river swim upriver and settle in the pond, and there are a variety of fish in the pond.
However, some shrewd villagers contracted ponds to raise fish, although they were very shrewd and related, but they did not know how to breed. The fry stocked are mainly raised by nature, and a few hundred yuan of fry is enough, but the rate of return is very large.
However, because they don't know how to breed, they only put fish fry, the aquatic plants in the pond are relatively dense, and the silver carp in it often breathes outside the water.
The main reason for this is the lack of oxygen, because there are too many aquatic plants in the pond, and the contact surface between the water surface and the air is insufficient, resulting in insufficient oxygen in the water, and the silver carp often floats its head and its mouth becomes wider.
And due to the cover of aquatic weeds, the water quality is relatively fat, the water quality is blackened, and the body color of the silver carp changes with the color of the water body, becoming darker, so there is a black "duck-billed silver carp", which is exactly the same as these silver carp in the video.
Finally: the man's pond fishing, the big head of the big head fished out is wide, like a duck's beak, this is not a new species, but a lack of oxygen in the water body, due to the lack of oxygen caused by the deformity of the silver carp.
