9 Kinds of Fish You Shouldn’t Eat

Dollarfish

The dollarfish contains gempylotoxin, a substance that is hard to metabolize and may cause indigestion. Luckily, grilling or frying the fish can reduce the levels of the toxin.

How to choose fresh fish?

You can easily tell fresh from bad fish from the shiny scales and clear eyes. Just take a piece in your hands and check the tail – if the fish is spoiled, the tail will be lowered. Gray grills and dry fins also indicate that the fish is bad.

When buying live fish, you should get them from a tank with clear water and pick the fish close to the bottom. If you’re into fishing, make sure to fish in waters that aren’t contaminated with mercury.

Many people love salmon, but aren’t even aware of the quality of salmon fillets served in front of them. The piece of salmon you ordered should have chunks and white threads. If the meat has bright spots on the skin, the fish has been caught during its spawning season and won’t taste much good.
