Large freshwater fish
When shopping, many people like to eat big fish because they have more meat and fewer bones. It is easier to remove the bones from larger fish than from smaller fish. That’s why large freshwater fish often have higher prices than smaller fish. However, few people know that most large freshwater fish weigh only about 1.5-2kg and have been raised for many years with a lot of care. But there are also larger fish weighing from 4-7kg that are being sold.
For this type of fish, you should not buy them because they may have been injected with growth hormones or have lived for a long time in muddy areas, which increases their chances of accumulating pollutants. In particular, for these fish to reach such sizes, the fish farmers have to feed them with a lot of growth-stimulating substances for a long period of time. If we regularly eat these types of fish for a long time, it can lead to many dangerous chronic diseases.
Poisonous snakehead fish that should not be eaten in any form
Swollen fish belly
When going to the market, if you see dead fish that are not moving but have a very swollen belly, it means that they have been dead for a long time. The prices of these types of fish are usually cheaper. At the same time, the internal organs are damaged, causing gas to accumulate, resulting in a swollen belly. According to nutrition experts, when fish die, their immune system weakens and free-floating bacteria thrive. The decomposition process produces organic acids that create a foul smell and change the color and protein content of the fish.
Also, when dead fish have been lying for a long time, their flesh decomposes and produces toxins. People who eat this type of fish can experience acute poisoning, such as digestive disorders, bloating, indigestion, abdominal pain, diarrhea, etc. Therefore, these types of fish, even if they are cheap, should not be purchased.
Catfish/mandarin fish

Catfish from Vietnam is considered dirty and should be avoided. Therefore, you should not buy these types of fish for daily consumption to prevent potential chronic diseases.
