Do blackfish have predators? What are the predators

Blackfish have natural predators, and the natural predator of blackfish is the salmon.

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, except for Kanas Lake in Xinjiang.

There are still a small number of remains.

Salmonidae belongs to the order Salmoniformes, Salmonidae, Salmonidae, Salmonidae, and Zoroichthys. Commonly known as Zheluo fish, Zheluo fish, Zhelu fish (northeast), and big red fish (Xinjiang), it is a critically endangered fish. The body is long, slightly flattened, cylindrical.

The head is flattened, the snout is pointed, the mouth is large, and the mouth is disposed. Maxilla.

distinct, free, extending posteriorly behind the posterior margin of the eye.

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.

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.

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.

The natural predators of blackfish are sharks, swordfish, yellowfin tuna, etc.

1. Sharks. The shark is one of the main predators of the blackfish. Sharks are one of the apex predators in the ocean and quickly prey on blackfish by sensing information such as their movements, smells, and electric fields.

2. Sailfish. Sailfish are also one of the natural predators of blackfish. The swordfish is a carnivorous fish that swims at high speeds and is well suited for hunting down small fish. They use their fins to bring small fish close to the surface, and then use their tails to strike quickly to prey on them.

3. Yellowfin late tuna.

Yellowfin tuna is also one of the natural predators of blackfish. The yellowfin tuna is a high-speed swimming carnivorous fish that can chase prey in the ocean at speeds of more than 50 kilometers per hour, and can visually detect the surrounding electric field to facilitate prey.

The environment in which the black fish grows:

The blackfish is a carnivorous fish that lives in the ocean. They are mainly distributed in the South China Sea, the East China Sea and the Yellow Sea. Blackfish prefer to inhabit waters with overgrown aquatic weeds or silt bottoms, and usually live in waters such as sandy beaches, coral reefs, rocks, and gravel.

These environments are very important for the survival of blackfish.

Blackfish can adapt to a wide range of water depths and temperatures, preferring warm, nutrient-rich water bodies. In search of food, they swim into the shallows and flick the sand with their tails to spot prey lurking in the sand.

However, human activities are becoming more and more frequent, environmental pollution is becoming more and more severe, and the living environment of blackfish is becoming more and more harsh. Therefore, human beings must protect the environment and protect these precious marine biological resources.

1. The black fish is the king of freshwater fish, and it is not afraid of any fish, so the black fish generally cannot be kept with other fish.

2. The snakehead is a carnivorous fish, fierce by nature and has a large appetite. Predators generally vary depending on the size of the fish. Juvenile fish mainly feed on rotifers, flexopods, cladopods and midnight mosquito larvae. Juveniles are mainly known for feeding on the larvae of aquatic insects, small fish and shrimp, etc.; Adult fish feed on a variety of small fish and shrimp.

The predatory fish species vary greatly from body to water, but are usually the dominant population in that area.
