The main meat we consume on a daily basis is chicken, duck, beef, sheep and pork, in addition to fish, which is also a common food we consume.
However, it should be noted that the heavy metals and parasites contained in some fish are very bad for human health, especially the last one, which is difficult to prevent!
Scavengers, considered the dirtiest fish in the world, are controversial, but their existence is not without value. Even if they are not edible, they can be used as an ornamental item.
However, the introduction of this fish has caused dissatisfaction and doubt.
When we first introduced scavenger fish, we were mainly attracted to their "eat everything" characteristic. As omnivorous fish, they eat waste from the tank, such as carrion and animal waste, thus cleaning the tank.
We brought in scavengers in the hope that they would become cleaners of the fish tank. However, we didn't expect that they would be so costly as cleaners!
The role of scavengers in fish tanks and fish ponds is not just "cleaners", they not only clean up the excrement in the fish tanks, but even sometimes swallow fish eggs. This kind of behavior of "cutting off children and grandchildren" has disappointed people's expectations, and the vitality that was originally regarded as an advantage has become a disadvantage.
Although the scavenger's tenacious vitality makes it almost ubiquitous in the country, it does not mean that it does not have natural predators.
American crocodiles and otters have a soft spot for scavengers and love to bite into their crunchy texture. However, in some parts of our country, the number of scavengers has reached the point of overflow.
But what is confusing is that since scavengers mainly feed on garbage, few people are willing to try their consumption. Even more worrying is the unimaginable number of parasites and bacteria in the scavengers.
Still, from a foodie's point of view, the poor quality of the scavenger's meat is also a problem that cannot be ignored.
You may not be familiar with the name, but it is actually a relatively common fish in China's Xinjiang, Inner Mongolia and Heilongjiang river basins. In Russia, pike is also a common ingredient.
Juvenile pikes have a docile personality, but when they become adults, they change their temperament and not only eat an amazing amount of food, but also hunt a variety of other fish. When caught, they bite like mad dogs, hence the name "pike".
Dogfish is highly prized for its rich medicinal properties and delicious meat. In addition to its effects on reducing fever and preventing plague, it is also highly valued for its unique organs such as the jawbone, heart and bile.
Compared with other fish, pike has very few spines and tender flesh, so it has become one of the economic fish. Still, there are many people who have a "not clean" view of dogfish.
This is because dogfish have a diverse diet, and in addition to preying on other fish, they also prey on animals such as frogs and rodents, which may carry bacteria and parasites.
However, most of the pike on the market today are farmed, not wild, so there is no need to worry too much about the health issues.
Tilapia, nicknamed "garbage fish", has a tenacious vitality and can survive even in stinky gutters. They are both exotic species and scavengers, and neither is afraid of the cold, but tilapia is afraid of being eaten.
Although tilapia is cheap and tastes good, due to the popularization of farming technology and the guarantee of cleanliness, there are still many people who misunderstand it.
Tilapia originated in Africa, and despite the harsh environment in Africa, tilapia thrives in stinky ditches. Tilapia can also be found in some of the country's most polluted areas, where water bodies are often polluted by factory sewage and domestic sewage.
Therefore, many people recommend eating less tilapia. However, the reality is that most of the tilapia sold in the market is farmed, so there is no need to worry too much about pollution.
A Commoner Delicacy with Deliciousness and Controversy Although silver carp used to be a regular at the family table, especially because of its affordability, you know what?
The bile of this fish is poisonous and must be thoroughly disposed of before consumption. Still, for fish lovers, this isn't a problem. So, why is silver carp considered "dirty"?
Silver carp is a filter-feeding fish that feeds mainly on phytoplankton and organic detritus, which may contain substances that are harmful to humans. Therefore, whether the silver carp is clean or not depends on the water environment in which it lives.
In addition, some people think that silver carp is "dirty" because of its earthy smell. In fact, silver carp is a medium-purine food, and for gout patients, it should be avoided.
Although the catfish lives in stinky ditches and polluted waters, and the food** is also garbage and carrion, he is not as disgusting as the scavenger who is known as one of the dirtiest fish in the world.
It turns out that the reason why people have a misunderstanding about the reputation of the catfish is because it has a layer of slime on its body, which looks disgusting and even makes people afraid to touch it. However, all we eat is farmed catfish, so we don't have to worry about the wild catfish we eat.
Similarly, despite the large scale of captive-bred eels, they are also very large"Dirty"。
The main reason why yellow eel is considered dirty is that its head may contain a large amount of pesticides and heavy metal residues. Therefore, when making yellow eel vegetables, decapitation is an essential step.
However, it is important to note that while decapitation can remove most of the dirt, it does not completely eliminate the presence of parasites. In order to protect our health, high-temperature sterilization is also necessary when cooking this type of dish.
In conclusion, the main reason why these fish are considered dirty is that wild ones are often dirty. However, the yellow eels on the market are usually farmed in captivity and are safe to eat after proper processing.
