What kind of fish is the natural predator of the blackfish? Do blackfish have predators? What are th

In our hometown, because there are many rivers and abundant water resources, there are a lot of black fish, and when someone clears the fish pond, they also found more than ten or twenty catties of big black fish, and the head bowl is so big!

However, in our place, the old people call the black fish "filial piety fish", the reason is very unbelievable, that is, the female black fish will become blind for a period of time after spawning, and cannot see things, so the female black fish can not find food at this time, after all, the black fish eats meat, and it is very difficult to catch other fish to eat, and it is very difficult to see it, so at this time, there will be a lot of black fish seedlings into the mouth of the female black fish and become food to repay their mothers.

Blackfish are very reproductive, and can hatch hundreds of blackfish at a time, but in reality, the number of blackfish in a pond is very small, and part of the reason is that the blackfish seedlings are eaten by their mothers. Because the black fish is destined to be eaten by his mother from birth, the black fish has a very ** personality, and those who can survive are powerful. Small black fish usually move around the pond and eat small shrimp and other creatures, but they are also eaten by other large black fish and white fish.

When the blackfish grows up, they will live in the middle and depths of the fish pond, and at this time the blackfish will begin to kill in all directions, even the catfish will not escape death. The most powerful thing is that adult blackfish will also catch blackfish seedlings to eat, so although blackfish have strong reproductive ability, they are under great pressure to survive and compete, and they can survive all the way. The biggest natural predators during the hatchling period are their mothers, adult blackfish, catfish and other fish, and the adult blackfish mainly die at the hands of other blackfish and people.

The underwater food chain is connected layer by layer, real and brutal.

The blackfish itself is also at the top of the pyramid in the entire water food chain, but that is limited to the big blackfish. In the beginning, the little black fish did not have any effective means to defend against the enemy. When encountering other carnivorous fish, they can only turn around and flee, and if they can't escape, they can only become the mouths of other fish.

In addition to those carnivorous large fish, there are many other animals in the water body that pose a great threat to the small black fish. For example, rats, frogs, snakes, water birds, etc., they will treat those small black fish that have lost the protection of the broodstock as a good meal.

In addition, the blackfish also suffer from another threat as they grow - food shortages.

In the same water body, there are more carnivorous fish, and such a situation will be formed in the later stage - there are not enough small fish to eat.

If there is no food, then the whole food chain will collapse, the skin will not remain, and the hair will be attached? What awaits the blackfish is only death.

Blackfish are freshwater fish and have no natural predators in freshwater. The natural predator of the blackfish is the two-legged animal on land - man! Because people (especially Cantonese people) think that eating black fish is very "supplemental", if you are injured and hospitalized, eat black fish to build muscle quickly, and the wound recovers quickly, so black fish is also known as raw fish.

As a result, blackfish are overfished and killed, and there are fewer and fewer blackfish in the wild in nature.

The salmon grows at a fast rate and develops at an equal rate, making it a large economic fish. Generally, individuals are more than 3 kilograms, and the largest ones can reach 50 kilograms, and they are more than 1 meter long. The meat is delicious and tender, and it is a nutritious fish, and it is also a specialty of the alpine region, and it is a precious food in the production area.

In addition to the northwest and southwest of China, the water tiger fish has its distribution in most areas, and its main distribution area is in various rivers, mainly living in the middle and pelagic layers of rivers, his swimming speed is very fast, his action is very agile, and its main food is also a variety of freshwater fish, including the extremely fierce black fish.

The giant salmon is a rare cold-water carnivorous fish in the north, with a body length of several meters and a weight of up to 100 kilograms. Fierce and alert by nature, it hides in deep water for many years, and its body is reddish-brown during the breeding season, and it is known as a big red fish. Today, it is extinct in most parts of the world, with only a few remnants remaining in Kanas Lake in Xinjiang.

Look at the individual of the black fish, the newly hatched black fish, or the small black fish fry, the black fish at this stage, generally have the protection of the parents of the black fish, if the parents are in the basic survival rate at this stage, there is no so-called natural enemy, of course, it is possible to give a few pecks to the birds in the sky by chance. If there is no parental protection, it is generally considered that everyone is dead. When the black fish grows up, in nature, the fish of the same size basically have no natural enemies, and if you want to say that there is a real fight, I think there is only a eel.

The eel is known as the king of freshwater, and a cod of the same size is not necessarily a match for a black fish of the same size! The little black fish is basically not alive when it is attacked by the big eel! Eels are the most active species! Blackfish is just an ambush!

The blackfish is also a cannibalistic species, and the blackfish is very territorial, and the adult blackfish will ambush all kinds of fish that pass by its territory! So the little black fish who strayed into the territory is a little worried!

Salmon can eat blackfish, but it's rare. Generally speaking, blackfish have no natural predators in China except humans.

The natural predator of the black fish is all the ferocious carnivorous fish, the big ones eat the small ones, and of course the big black fish can also eat other small fish.

Freshwater eels will eat juvenile black fish, which will limit the reproduction of black fish to a certain extent.

There are special cases, such as bears nearby, bears, people, people, and most likely parasites.

After all, it's not small, and it doesn't live in shallow water, and it's not a marine fish, so it doesn't have anything to eat for a living.

Typing is not easy, such as satisfaction, hope.

Natural predators have appeared, and since there is a lure, there are fewer and fewer blackfish.

Adult eel have black fish on their menu.

The scientific name of the black fish is snakehead.

It is the most widely distributed and most productive snakehead fish, which lives benthic and mostly inhabits aquatic grasses.

Clumped waters, and black fish to the environment is highly adaptable, rivers and lakes are distributed, can grow in the water temperature environment of 0-41 degrees, the temperature below 0 degrees will be buried in the silt for wintering, in the process of breeding black fish, bait should be fed twice a day.

The black fish is also called snakehead, thunderfish, and mullet.

Wealth fish, fire head fish.

Snake fish, is the most widely distributed, the largest production of snakeheads, fierce nature, the front end of the body is cylindrical, the head is pointed, similar to snakes, the back part is flattened, the teeth are small, the body color is gray-black, the abdomen is lighter, and there are irregular patches on both sides.

Blackfish are demersal freshwater fish.

It inhabits the waters overgrown with aquatic weeds, has strong adaptability to the environment, and is widely distributed in rivers and lakes, and the black fish has low requirements for water temperature, and can grow in the water temperature environment of 0-41 degrees, and when the temperature is below 0 degrees, it will hide in the silt for wintering.

In the process of breeding black fish, bait should be fed twice a day, mainly small trash fish and shrimp, and the amount of feeding should be judged according to the growth situation, the period when the black fish is vigorous, the daily feeding amount is 10% of the body weight, and the growth is weaker stage, the daily feeding amount is 3% of the body weight, so as not to produce waste.

The natural predator of the blackfish is the salmon.

Zheluo salmon, commonly known as sea emperor beast, Zheluo dragon, water dragon (northeast), sea dragon (Xinjiang). It belongs to the salmoniformes order Salmonidae genus, which is a large carnivorous and ferocious fish, with a body length of 2-5 meters in adulthood, body length, slightly flattened, and cylindrical. The head is flattened, the snout is pointed, the mouth is large, and the scales are very small.

It is a second-class endangered protected animal in the world.

The salmon is very voracious and is one of the most ferocious species of freshwater fish. Foraging time is mostly before sunrise and after sunset, swimming from deep water to shallow water to the shore to hunt other fish and snakes, frogs, rodents and water birds in the water, and other times lurking in the shaded water on both sides of the stream.

Feed all year round, and when the water temperature is slightly higher in summer, the appetite is poor, and even there is a phenomenon of fasting; Feeding is not stopped during the winter season, and feeding is stopped only during the reproductive period.

Distribution of salmon

It is mostly distributed in the Heilongjiang, Tumen and Irtysh rivers in China. Abroad, it is distributed in the Lena River to the Pechora River in Siberia, Russia, and the upper reaches of the Volga River and the Ural River in Eastern Europe.

There is no detailed report on the abundance of salmon, but according to the Fishery Resources of Heilongjiang Province (1985), the number of salmon in the Chaxiang River of Heilong Orange has decreased significantly compared with the past, and the catch in the province is almost non-significant. It is mainly due to the overfishing during the breeding period, which has greatly reduced the insect catcher population, and the environmental pollution and pollution damage the environmental conditions for survival, resulting in a significant decline in resources. No effective protection measures have been developed.
