9 Types of Fish You Should Eat in Moderation

Last Updated on

Fish is one of the healthiest, naturally-occurring foods for humans. The good fat contained is fish is beneficial for your health. However, there are certain types of fish you should stay away from—fish bred in farms and fed antibiotics—that are harmful to your health.

FeedFond has collected a list of 9 types of fish that you can do without.

#9 Oilfish

Also known as the dollar fish, this type of fish contains a waxy substance called gempylotoxin, which may cause indigestion. If you must have this fish, it’s best to have it fried or grilled.

#8 Seabass

Seabass contains mercury, which is harmful to the nervous system. Instead of sea bass, opt for other types of fish for consumption. For adults, it is recommended to take a max of 200g of sea bass, while for children, the recommended intake is 100g.

#7 Tilefish

Tilefish is one of the fish with the highest mercury content. They are sometimes caught without paying attention to the rules of tilefish fishing. This may lead to food poisoning. Tilefish is not at all recommended for women and children. Men are allowed to have only a max of 100g of tilefish.

#6 Pangasius

Pangasius originated in the Mekong River in Vietnam, one of the most contaminated rivers. This fish contains high levels of cancer-causing elements like nitrofurazone and polyphosphates. This fish is not at all recommended for human consumption.

#5 Eel

The fat in eel easily absorbs industrial and farm waste found in water bodies. The American species of eel has the highest level of contamination and their European counterparts have high levels of mercury. Monthly consumption of eel for adults is recommended at 300g while for children, it’s 200g.

#4 Tilapia

Tilapia fish don’t have the good fats associated with fish. So, it’s not healthy for people with heart diseases, asthma, or arthritis. Tilapia fish can raise cholesterol levels and makes the human body more sensitive to allergens.

#3 Tuna

Blackfin and Bluefin tuna contain high levels of mercury. Tuna doesn’t occur naturally in freshwater and are bred in farms where they are given antibiotics and hormones that are not healthy for humans. Tuna is not recommended for children and for adults, a monthly consumption of 100g should be the limit.

#2 Mackerel

Mackerel also contains very high levels of mercury and should be avoided. However, the Atlantic mackerel is the least harmful and can be consumed as much as anyone wants to. For adults, a monthly consumption of 200g of mackerel is recommended and for children, the limit is 100g.

#1 Imported catfish

Catfish are fed hormones in farms, especially in the Asian countries where they are bred. If you can find free-grown catfish, that should be selected over imported catfish.


How to Choose Good Fish

Fresh fish vs. spoiled fish

Fresh fish have clear eyes, shiny scales, bright red fins and gills, and a tail that is not low. Spoiled fish have clouded eyes, gray fins and its gills and tail hang weakly.  

Fish tank

Live fish in a tank that is closer to the surface and is in clear water are better than the one which is not in clear water and closer to the bottom of the tank.

Caught live

If you catch live fish and cook it, check the level of mercury in the water from where you’re catching the fish.

Salmon steaks

Choose salmon steaks that have white marks. If the steak is excessively red, chances are that they have been dyed. Don’t choose fish with white spots on the skin as it indicates they have been caught in the spawning season, and so, it will not taste good.
