Dogfish, because of its "hungry food" and "no refusal to come" characteristics, is nicknamed "underwater mad dog".
was originally the "overlord" of the Heilongjiang water system, but now in 2021, it appeared in the Yellow River, 2,000 kilometers away.
As the local anglers caught this unexpected fish, everyone present fell into deep thought.
And what impact will the invasion of pike have on the waters of the Yellow River?
- Mad Dog Underwater ·
Dogfish, as the name suggests,He has a mouthful of dog teeth, and was called "dog name"., however, the temperament of this freshwater fish is far less docile than that of dogs.
They are hunting their prey,Not only does it bark like a mad dog, but it also bites the prey that has just entered its mouth along with the water.
With a strong ability to survive and hunt,It has become a predatory beast in the northern Asian water system, and is a medium to large predatory species.
Because it has a flat fish lip that resembles a duck's beak,This allows pikes to better catch and swallow prey into their mouths.
And the sharp upper teeth can not only help it easily bite through food or the body of enemies,You can also hook the uneaten food to your teeth and become "combat rations".
Adult pike can grow into a behemoth with a body length of 1.4 meters and a weight of more than 70 poundsIt is an inevitable choice for northern anglers to exercise their arm strength and experience the feeling of fishing.
I thought I had such a figure,Dogfish are like land beasts, Siberian tigersAs a result, they choose to live in groups and rely on the cooperation between teammates to increase the success rate of hunting.
Of course, the cruelty of the pike is not only for other fish species, as long as they are hungry and can't find foodThey will also choose to eat juvenile fish, fish eggs, or the elderly, the sick and the sick.
is so fierce and cunning, how can he not be worthy of the name of "underwater mad dog"?
——Dogfish has a long lifespan·].
As for how long pikefish live, some say,They range from 10 years to "unlimited".Why do you say that?
It turns out that as of now,Among the pike found in our country, the longest lifespan is 70 years old
And that's not all, in the 70s of the last century, in a lake on the territory of Russia,I even caught a pike in his 200s.
It is reported that this dogfish was actually put into the lake by the Tsar back then, although there is no definite evidence for this legendBut this also indirectly shows that the longevity of dogfish is not a secret in the eyes of people around the world.
So why did it live so long?Naturally, it is inseparable from the "dog". They muddy the water with their fins and then set them asideWhen the small fish want to compete, they swallow it at a very fast speed, so that many fish die before they can see who their opponents are.
In addition, pike is also an "omnivorous" fish species, in addition to eating fish and shrimpThey will also challenge themselves to catch frogs, waterfowl or rats prowling on the shore.
Dogfish are very intelligent when they see prey on the shoreThey hide their bodies with the help of aquatic weeds and siltWhen the prey does not perceive the danger and walks to the water's edge, they will use the powerful tail of the fish to make a lunge and grab the prey.
It doesn't matter if these prey are sometimes bigger than it, as long as they are dragged underwaterDogfish can bite and swallow in a hidden place.
It is precisely this appetite that makes the dogfish grow quickly into a hegemon, and without the bullying of other fish, it can naturally live a long life.
——Why do pikes appear in the Yellow River Basin?—
The hometown of pike in China was originally the Heilongjiang River Basin, as an invasive speciesDogfish are large and hardyAnd in the northeast of our country took root.
It stands to reason that there are no connecting rivers or culverts between the Yellow River and the Heilongjiang RiverSo why can the pike appear in the Yellow River along the Heilongjiang River?
In fact, most of it is caused by human factors.
When people are accustomed to seeing freshwater fish such as carp and crucian carp, they will be curiousBring the rare pike to your home to watchSome fish sellers will also be attracted by the market and raise more pike.
And when it comes to heavy rains in the summer,The pikes will flee as the water risesIt then follows the rivers of the provinces into the Yellow River.
Because the Yellow River is located in the warm Central Plains, there are abundant freshwater fish resources here, and the pike seems to be hereFoodies have gone to heaven.
Except for the fact that the higher water temperature than Heilongjiang can control the pike a little, the pike has no opponent here at all.
The dogfish's strong predatory ability will soon reduce the number of fish in local rivers, disrupting the original species balance and eventually leading to the endangerment of some species.
Then someone said:Don't they all say that Chinese "foodies" can eat it?What's the point of a few pike?
However, even if the people can eat it again, they will not eat the pike to extinction, not to mention the impact of an adult pike on the aquatic environmentIt's enough to keep other fish species from finding a habitat for a short time.
In addition,Dogfish also carry parasites and pathogens in their bodiesOnce spread, it poses a health threat to other aquatic species, affecting the entire ecosystem.
Finally, like the huge size of the pike, it is also extraordinary in terms of edible and medicinal value.
——The edible and medicinal value of pike·].
First of all, pike is rich in vitamins, and its flesh is very goodIt has the effect of moisturizing yin and dryness, strengthening muscles and bones.
In addition, the jawbone of the pike is widely used in the field of traditional Chinese medicineIt has the effect of hemostasis, fever reduction and antidiarrheal.
And the heart and bile of the pike,It can alleviate the gastrointestinal discomfort of the human bodyImproves digestive function.
Pike, like other freshwater fish speciesRich in protein and unsaturated fatty acidsAfter eating, it can supplement the nutrients needed by the human body, enhance physical fitness, and improve immunity.
Because the pike meat is smooth and tender, the pike that is served to the table is also "in a variety of forms".There are those that are braised or sliced with sashimi, stir-fried, simmered, and even grilled over a fire.
No matter what kind of pike it is, after it is made, it is fleshy and tendonous, and there are many aquatic products that have begun to breed a large number of pike, so it is the best in the marketIt has also remained at about 20 yuanIt has become a home-cooked dish everywhere.
Of course, we still don't want pike in the Yellow RiverThere will be a situation like "Yangtze River eel overflow".
After all, at that time, it will not be the cry of the Yangtze River, but the cry of the Yellow River.
