Fish is delicious and healthy, but there are certain types of fish that will do you more harm than good. Below you will find 9 kinds of fish that you should only eat on the odd occasion, or not at all.
Imported Catfish

Consumption: Not recommended
Catfish can grow to quite a considerable size. However, to accelerate their growth, many fish farmers feed them growth hormones, especially those from Asian countries. Free-grown catfish are a lot less dangerous and have more nutritional value.
Mackerel

Consumption: Adults 200g, children 100g per month
Mackerel contains mercury, which is a disease-causing chemical that the human body cannot eliminate. The Atlantic mackerel is the least dangerous in this regard, and you're safe to eat as much of this as you like.
Tuna

Consumption: Adults 100g per month, not recommended for children
Tuna has a lot of mercury, especially blackfin and bluefin tuna. Furthermore, there's precious little free-grown tuna in stores as it is near extinction in the wild. All the tuna you will find comes from farms where it has been fed antibiotics and hormones.
Tilapia

Consumption: Not recommended for those with heart disease, asthma, or arthritis
There aren't many healthy fatty acids in tilapia, yet its concentration of unhealthy fats is almost as high as in lard. Excess consumption of this fish leads to an increase in cholesterol levels and makes the body more prone to allergens.
Ele

Consumption: Adults 300g, children 200g per month
Eels contain a lot of fat and, as a result, they easily absorb any industrial and farm waste that is in the water they live in. American species of eel have the highest levels of such toxicity. Furthermore, European eels are well known for being contaminated with large amounts of mercury.
Pangasius

Consumption: Not Recommended
Most of the pangasius that we can buy in our stores come from Vietnam, namely from the Mekong River – one of the most contaminated bodies of water in the world. Moreover, this fish contains an elevated level of nitrofurazone and polyphosphates, which are known carcinogens.
Tilefish

This fish contains more mercury than any other fish, and it is often caught in breach of health and safety rules, leading to an increase risk of food poisoning.
Sea Bass

Consumption: Adults 200g, children 100g per month
Sea bass also contains a lot of mercury. Furthermore, if you order this somewhere as a filet, there is a very high chance that you will be given pangasius or some other cheaper fish.
