Do you know? According to statistics, there are currently more than 6,000 kinds of freshwater fish in the world, in fact, in addition to the fish seen daily, there are many fierce freshwater fish in the water, and the news of fish attacking human beings is also endless. Some of them can even reach 100 pounds in size, and even experienced anglers may not know them when they see them. Take an inventory of some of the fiercest freshwater fish today.
The first type of blackfish
Blackfish is also known as mullet fish, also known as snakehead fish. This fish is gray-white, with irregular black spots, the body shape is like a cylinder, the head is relatively flat, this fish is not only very fierce by nature, but also reproduces quickly and eats a lot. If he is allowed to grow in a lake, he will eat all the fish in the lake, and if he is short of food, he will even eat his own offspring, which can be said to be "six relatives do not recognize".
And as a fish, why can blackfish be so domineering? That's because there are many small teeth in the mouth of the blackfish, these teeth are staggered, becoming a weapon for blackfish to attack other aquatic animals, when hunting, blackfish tend to hide in places where the water is turbid or aquatic weeds are intertwined, and then when other small fish pass by, they suddenly attack and swallow them in their mouths.
In addition, blackfish are also very adaptable, and some can even glide on land. When the river dries up, like hibernation, the blackfish will insert its tail into the mud, leaving only the head to exhale outside, leaving the body in a dormant state; When water is plentiful again, they will return to normal.
In the United States, blackfish have even begun to flood, eating up the rest of the lake's fish, and are called "water devils" by the Americans. However, in the mainland, because black fish is delicious and has high nutritional value, it has become a "delicacy" on the mainland table, and the quantity has been controlled.
The second type of horsemouthfish
Horsemouth is a freshwater omnivorous fish, but prefers to eat meat, they live in clear rivers, are social animals, and are 10-20 cm long. However, although the size is not large, this fish is very lethal, ferocious by nature, mainly other small fish and insects in the river, good at jumping, often jumping out of the water, preying on insects flying on the surface of the lake.
In addition, this fish is also very greedy, and when encountering food, it often "can't control itself" and causes excessive obesity. Although this fish is strong in the water, it still can't escape human chopsticks, and wild mouthfish are becoming increasingly rare due to overfishing this year.
Third place alligator eel
The alligator eel is a large fish, generally 1.2-1.8 meters long, the largest can even be up to 3 meters, and weighs 45-72 kilograms. This fish is known as a large beast of predation in the water that is more feared than man-eating sharks, and for the mainland, alligator eels are invasive species.
In the 80s of the last century, the alligator eel was introduced to the mainland. However, due to its large size, the possibility of domestication is small, so many alligator eels are released in wild rivers. This fish is a carnivore and is extremely destructive to rivers. Therefore, the released alligator eels frantically gnawed on the fish in the water, causing serious damage to the aquatic system of the mainland.
In addition, the eggs of the alligator eel are also highly poisonous, and if someone provokes him, he will attack him. Similar to snakes, alligator eels feed mainly by swallowing. It is known that they can swallow up to a quarter of their body size, so alligator eels are also known as "water killers". As long as you see traces of alligator eels in the water, you can basically determine that there are no other fish in this lake.
What is less known is that alligator eels are still "living fossils". According to statistics, with strong survival skills, alligator eels have survived on the earth for more than 100 million years and belong to prehistoric fish.
Fourth place giant ray
The giant ray, also known as the eagle tank, is a tropical fish, huge in size, up to 2 meters long, and its weight is amazing, and some can even grow to more than 200 pounds. It is currently the largest fish in the family Cerambycidae, and in terms of size, it is no exaggeration to say that the giant ray is the peak species among catfish.
This fish can live in fast-flowing rivers, just by his fat. After all, with more than 200 pounds of giant fish, ordinary rivers will definitely not be able to wash him away, and the body of the giant fish is streamlined, so that they can shuttle freely in the water. But the most frightening thing is his sharp teeth like nails.
Although the giant ray is large, dull, looks like a harmless look of humans and animals, but if you open his mouth, you will find that the teeth of this fish are thick and sharp, not at all like normal fish will grow, if the giant ray is put into the water, his hunting is even comparable to the eagle, because of the huge size, the giant ray is also known as "water tank", belongs to the mainland second-class protected animals.
The fifth species of Gero salmon
Gero salmon is a cold-water freshwater predatory fish found mainly in northern Asia. This fish has a long body, generally more than one meter, the longest can reach more than four meters, the body is slightly flat, cylindrical, generally living in the very low, turbulent river, has the habit of migrating.
This fish is very voracious and the dark periods before sunrise and after sunset are perfect moments for him to forage. In addition to the fish that prey on other fish in the water, frogs and snakes and rats near the shore are also included in his recipe. However, the appetite of the salmon is affected by the temperature, and this cold-water fish will significantly reduce its food intake in the hot summer, or even stop eating, and his appetite will return to normal in the cold winter.
The famous Kanas Lake monster is the Jero salmon. In the Altay region, locals often see large fish in the water, and locals also call this fish "big red fish". Rumors about the Kanas Lake monster have also been in the news many times, and it has later been confirmed to be a giant gero salmon.
The sixth species
Darcher's fish is one of the oldest fish, his origin can even be traced back to the age of dinosaurs, as a fish that lived with dinosaurs, Dar's Ray still retains the characteristics of primitive fish after hundreds of millions of years of evolution. This fish is huge, one of the largest freshwater fish, up to 5.6 meters long, and some even weigh up to 1,000 kilograms, which can be said to be a giant freshwater fish.
According to research, Darchen's rays are currently mostly distributed in Heilongjiang on the mainland. As freshwater fish, the Darlings are very "principled" and they will never swim into the sea. In addition, the lifespan of the Darchen is also very long, which can live for as long as fifty or sixty years. The fish are also active and foraging all year round, feeding mainly on small fish in the water and occasionally preying on some large fish.
The seventh species of catfish
Catfish have a wide distribution on the mainland, and they can be seen in various regions. This fish has a smooth body, a layer of mucus on the body, and four long beards, and its body is long and flat, which is very recognizable. In addition, catfish are huge, more than one meter long, and large catfish can weigh up to 100 pounds.
The huge size allows them to defeat most of the fish in the water, catfish are fierce and greedy, using other fish in the water as the main food, and catfish that grow to about 500 grams will attack and eat crucian carp, carp and other fish in the water, and some even prey on small birds or rodents.
