Everyone knows halibut vs flounder are among the most delicious sea fish species out there. People don’t take time to think about what separates these two tasty (and healthy) fishes, so I’d like to talk about some of the differences between them and which is generally better.

Halibut and flounder differ in their taste, color, and the way they are prepared. Halibut is flat and dark with a grayish hue, while flounder is usually lighter with a creamy white color. Halibut can be found in the north Atlantic ocean, Pacific Ocean, and Baltic Sea.

On the other hand, you might only be able to get your hands on flounder when dining out since it is more widely distributed than its cousin halibut.

What Is Halibut?

Halibut is a flat, white-fleshed fish that lives in the northern Pacific and Atlantic Oceans. It’s an incredibly popular dish among seafood lovers because of its delicate, buttery taste and versatile cooking qualities.

Halibut has a mild flavor and a firm, meaty texture that allows it to stand up to various cooking methods. Halibut can be pan-fried, baked, broiled, grilled, steamed, or poached, and it pairs well with many different seasonings.

A four-ounce portion of halibut contains roughly 25 grams of protein and just 130 calories. It also provides several important nutrients, including vitamin D, magnesium, and phosphorus.

Fresh halibut fillets are available throughout most of the year. However, there are strict regulations regarding the size and number of halibuts caught each year.

For this reason, large halibut fillets can be quite expensive; smaller fillets are more readily available and affordable.

What Is Flounder?

Flounder is a type of flatfish, which means it has two eyes on one side of its body. This curious feature evolved because flounders spend most of their time lying on the seafloor, waiting to ambush their prey.

They are typically grayish or brownish and have a relative smallmouth. Flounder is a firm-fleshed fish with a mild flavor and medium texture. It can be prepared in many ways, including pan-searing, grilling, baking, broiling, frying, and even making it into fish sticks.

Flounder is also commonly used in chowders and soups. Flounders can be found anywhere in cold coastal waters, including the Mediterranean Sea and the Atlantic Ocean.

The flounder you find at your local seafood market will likely be caught off the coasts of North Carolina or Massachusetts, though some may come from as far away as Iceland or Norway.

Halibut Vs Flounder: Key Differences

Today, we’re looking at two very similar fish: halibut and flounder. These fish are flatfish, which means they swim on their sides. But that’s not the only similarity.

They both live in the ocean and are found in waters worldwide. They both have a very mild flavor (sometimes described as savory) and a soft, flaky texture when cooked properly. So what’s the difference? Which is best? Let’s take a look!

Halibut is larger than flounder, which means that it takes longer to grow to its full size, which can be enormous! Halibut can weigh up to 500 pounds and measure almost 8 feet long.

Flounders are much smaller, rarely growing more than 3 feet long or weighing 15 pounds. Halibut has a leaner body type with fewer fat deposits, while flounder is usually fattier.

This makes halibut less forgiving if you overcook it, while flounder still tastes great even if you give it an extra minute or two on the grill. Halibut is also more expensive than flounder, so go for the flounder if you’re looking to stretch your dollar.

Both types of fish are low in calories and high in protein, and they are both excellent sources of vitamin D, omega-3 fatty acids, and selenium.

Halibut is a leaner fish than flounder — it has about 20% fewer calories and nearly twice as much protein — but flounder has almost twice as much selenium and more vitamin B12.

Frequently Asked Questions

Why Is Halibut Fish So Expensive?

If you’ve ever tried to buy halibut fish, there’s a good chance that you were shocked when you saw the price tag. There are many reasons why halibut is so expensive, and all of them add up to make this one of the most expensive types of seafood you can buy.

First, halibut fish take a long time to mature and begin producing eggs. This means it takes a long time for halibut populations to recover from fishing expeditions, contributing to its high price tag.

Additionally, there are strict limits on how many pounds of halibut can be caught each year, making it even more difficult for anglers to continue catching.

Are Halibut Bottom Feeders?

Did you know that halibut is a bottom feeder? When food sources in the sea are low, they go down to lower levels of the water column and feed on squid, shrimp, and other crustaceans. That is why halibuts are called bottom feeders.

What Is The Healthiest Fish To Eat?

If you’re looking for the healthiest fish to eat, it’s best to look at types of fish that are high in omega-3 fatty acids and low in toxins. Salmon, sardines, mussels, and rainbow trout are some of the healthiest fish to eat. They have a good balance of omega-3 fatty acids and are low in mercury.

In addition to healthy fats, seafood is rich in vitamins and minerals such as vitamin B12, selenium, and iodine.

Today, I hoped you’d learned a thing or two about Halibut vs Flounder. The number one thing these fish have in common is that they are both flatfish, which means they are both saltwater dwellers.

However, they differ in appearance and more, as you can see above. If you’re a serious fishmonger, you should choose Halibut over Flounder. It’s not that hard to tell them apart: Halibut looks flat, the eyes are all on the left side of its face, and lives in the sea.

The flounder is rounder and has its eyes on both sides of its face, and it swims in freshwater.
