Science Story: 3 healthy fish to eat more often and 3 to avoid

As it turns out, some types of fish deserve more attention from us, while catching and eating other species can be dangerous for our health and the environment. Let's find out the truth.

We all know that fish is an excellent source of protein and healthy fats, but of course everything is not that simple.

Super healthy fish to eat more often:

#1 Albacore tuna

The Albacore tuna has lower mercury levels compared to other tuna species, but only when it's troll- or pole-caught, as only young fish can be caught this way. When caught in cold northern waters, the Albacore tuna is also very rich in omega-3.

#2 Farmed oysters

These mollusks aren’t just nutritional and super rich in protein but they are also great for the environment. Oysters can improve water quality by eating nutrients and algae found in water.

#3 Mackerel

This fish is rich in omega-3, vitamin D, and phosphorus. The only con to this fish is that it spoils easily. Mackerels should be properly refrigerated to avoid this. A fresh mackerel should be eaten on the same day it's caught.

And now, 3 fish you should avoid:

#1 Bluefin tuna

This tuna was put on the 10 for 2010 list of threatened species by the World Wildlife Fund back in December 2009. Despite this, one bluefin tuna can be sold for as much as $177,000. The Environmental Defense Fund doesn’t recommend eating this fish.

Bluefin tunas have high levels of mercury as well as high levels of polychlorinated biphenyls (PCB), which can cause developmental and neurological problems in babies and children.

#2 Chilean sea bass

This fish, also called the Patagonian toothfish, is known for its buttery meat. Trawlers and longlines are used to catch the Chilean sea bass, which is really bad for the environment. These methods lead to the damage of the ocean floor and can seriously hurt sea birds.

The Chilean sea bass also has high levels of mercury. Adults can only eat it no more than twice a month. Children aged 12 or younger can only eat it once a month.

#3 Mahi-mahi

The mahi-mahi is also known as the dolphinfish. The Environmental Defense Fund has rated it as one of the least eco-friendly fish. When people fish for mahi-mahi, they unintentionally catch other sea creatures such as sea turtles, sharks, and even sea birds. These animals get caught in the fishing gear.

The photo of "farmed oysters" are in fact Abalone, a sea snail type. Oysters have an enclosed 2 part shell and look nothing like your photo.

#1- Learn the difference between an Oyster and an Abalone. #2- I see no health considerations concerning eating Dolphin/Mahi Mahi. Just because the enviros say catching them can effect other species does not make them unhealthy to eat. And I thought that is what this article was about.

Only fish I like is white fish (cod, halibut etc.) deep fried in lots of batter - probably the least healthy form of fish, but the tastiest!

I love walleye dipped in egg batter with corn flake crums then fried a minute and a half on both sides in coconut oil. Add a side of baked beans and Texas toast and you're in heaven

I love almost all fish. But mahi is my favorite! Mackerel is awesome when hot or cold smoked.

Wayne Roberts

I no longer eat seafood due to over fishing. I will however eat it if I know for sure how it was caught. i.e. scallop diving, not dredged.

Good information, and helpful in my decision making. BTW, those are not oysters, they're Pauwa (aka Abalone). The indigenous people of New Zealand (Maori) make beautiful jewelry out of them.

I like Albacore tuna once in a while. Mostly I eat trout (farmed rainbow) and wild salmon, and haddock

Patricia Price

I’ll stick to salmon and trout thanks!😊

I love Oysters and the Photo you Show are not Oysters

When I go to a nice restaurant, I usually order the mahi mahi. I like a white clean fish that doesn't taste too fishy & the mahi mahi is very white & clean tasting. Here in Southern Illinois our favorite is fried catfish, pond not river cat. The river cat has a strong fishy taste & has those dark oily spots of meat. Back to the article. Interesting & I learned a lot. I knew that some fish were higher in mercury but didn't know which ones.

David Holmes

Usually I eat fish twice per week, normally salmon and haddock. Red meat very rarely.

Norma Murray

I was brought up in a fishing town and loved all fish. Later in my late teens I discovered shellfish. Not too keen on Osters. Haddock and Scallops are my favourite.

Carol Moore

gerald hardig, me, too.

Caroline Weis

Albacore tuna is the only form of tuna I eat as well as Atlantic Salmon and cod. Can't stand the smell of oysters raw or cooked. Cat fish and trout are good as well.

andrew anna

I enjoy eating my seafoods.

ninakamwene

I am a meat eater, and the only fish I like is salmon which I eat very rarely. This was educational and informative. Keep it up Quiz Folks, and be well.

Hey! Oysters are delicious, but they aren't fish. They can give you hepatitis too which is certainly not healthy. And mercury in tuna is still mercury.
