What is the dirtiest fish in the world when it comes to blackfish

There are two theories about the dirtiest fish in the world, one is catfish and the other is blackfish, but most say catfish.

The dirtiest fish is inseparable from the environmental impact of its survival, and the black fish can generally lie dormant in the mud and sand like a loach. Benthic fish, usually inhabiting still water or micro-flowing water with overgrown aquatic weeds and soft sediment. The habitat of black fish is found in lakes, rivers, reservoirs, ponds and other waters.

They often dive to the bottom of the water to swing their pectoral fins to maintain balance. It has strong adaptability to the changes of environmental factors in the water body, especially to hypoxia, water temperature and poor water quality.

When a body of water is starved of oxygen, it can expose its head to the surface of the water. Posterior lateral flattening. The head is long, slightly flattened anteriorly, slightly raised posteriorly.

Oxygen from the air is breathed directly with the help of a suprabranchial apparatus consisting of a piece of bone extending from the upper branchial bone and the lingual and jaw on the dorsal surface of the first branchial arch in the gill cavity. Therefore, it can survive for quite a long time even in humid areas with little and no water. The survival water temperature of mullet is 0-41, and the optimal water temperature is 16-30.

When the water temperature reaches more than 8 in spring, it is often active in the middle and upper layers of the water body. It is active in the upper layers of water bodies during the summer season; In autumn, when the water temperature drops below 6, it swims slowly and often lurks in the depths of the water. In winter, when the water temperature is close to 0, they will live in the bottom mud and stop eating. Has a strong jumping ability. When the weather is hot and humid, and the water is raining and rising, the blackfish will often jump out of the water and escape along the pond embankment. When there is an impact of flowing water, it will also provoke the fish to jump and run away.

If the pond where it lives is short of bait, it will also move to other ponds, and its body will resemble a snake and move forward slowly. When the temperature range is 10 to 15, it can leave the water for 3 to 4 days.

Blackfish is not the dirtiest fish in the world, and neither is catfish. Although there has been a rumor circulating on the Internet that "catfish, the dirtiest fish in the world". In factCatfishIt is an omnivore, and its main diet includes aquatic insects, organic detritus, etc., and also eats animal feces, small fish, and live animals such as rodents.

But in aquaculture, animal manure is a cheap, non-toxic natural fertilizer that is no problem as long as it is properly handled.

Although catfish can survive in a dirty environment, this does not mean that they "love to live in dirty water". If the water is particularly poor, the catfish will also not grow well, will be poisoned, and even die, and the farm will never do such a money-losing thing as "polluting the fish pond". Judging from the data, the vast majority of catfish in formal aquaculture and regular water bodies do not have safety problems such as excessive heavy metals, and they can be eaten with confidence.

A little common sense, according to what you said, you can't eat green vegetables, and manure and pesticides are involved.

Black fish is not dirty and can be eaten. Blackfish is a common food fish with a large body, fast growth, and high economic value. Black fish has fewer bone spurs, a high meat content, and is rich in nutrients, which is higher than the protein content of chicken and beef.

As a medicinal use, black fish has the effects of removing stasis and renewing, nourishing and recuperating, and surgery.

After that, the consumption of black fish has the effect of building muscle and nourishing blood, promoting wound healing, and has very rich nutritional value. In addition, black fish meat contains protein, fat, and 18 kinds of amino acids.

It also contains calcium, phosphorus, iron and a variety of vitamins necessary for the human body.

Many fish will eat carrion, such as catfish, as long as the water quality in the area where the fish live is normal, the fish will be fine.

Blackfish is not the dirtiest fish in the world.

The dirtiest fish in the world, in fact, there are two sayings, some say it is catfish, some people say it is blackfish, and people agree that catfish is the dirtiest fish in the world.

Blackfish is a freshwater fish of the family Snakehead, the scientific name is snakehead, also known as thunderfish, mullet, snakefish, raw fish, etc., because it likes to eat carrion and often lurks in the silt like a loach and is considered to be the dirtiest fish, in fact, it is not, compared to catfish may be dirtier, but whether it is a black fish or a catfish as long as it grows up in clean waters, it is not dirty.

The habits of the blackfish

Black fish is a benthic freshwater fish, all over the country is generally distributed or farmed, like to inhabit the aquatic weeds or silt substrate waters, dissolved oxygen, water temperature, water quality and other water environmental factors have a strong adaptability, such as hypoxia when the black fish can breathe with the help of auxiliary respiratory organs, and even crawl on the wet soil, winter water temperature close to 0 when buried in the silt for winter.

Blackfish is a typical carnivorous fish, ferocious and very large, mainly feed on small fish, shrimp, frogs, aquatic insects and larvae, among which the fry stage feeds rotifers, scratch pods, cladopods, midge larvae, etc., the juvenile stage feeds on aquatic insects, small fish, small shrimp, aquatic insects, etc., and in the adult stage, it preys on small fish, shrimp, frogs, etc.
