What Is Grouper?

Grouper is a type of fish known for its large mouth. These fish are part of the same family as sea bass, and the largest variety of grouper is the Atlantic Goliath Grouper. The largest one ever caught was nearly 700 pounds. 

When it comes to enjoying seafood, grouper is one of the most popular types of fish. As a white fish, grouper has a mild flavor, which makes it perfect to serve with a variety of seasonings or sauces since the flavor of the fish isn’t overpowering.

There are hundreds of varieties of grouper, and each one has a slightly different flavor. While grouper is a safe and healthy fish to eat, you do need to pay attention to the amount you’re consuming due to the presence of mercury. This is especially true for pregnant women or young children since they’re more susceptible to mercury poisoning.

Due to the amount of mercury in grouper, it’s recommended that most adults avoid eating it more than twice a month. Also, it’s not recommended for young children to consume grouper more than once a month. If you still want to eat fish twice a week, you can occasionally switch grouper out with lower-mercury fish like tilapia.

What Is Snapper?

Snapper is also part of the sea bass family. The most common type of snapper to eat is red snapper.  It’s also one of the most popular types of white fish. While you can find snapper all across the globe, most of the snapper we eat comes from the Gulf of Mexico.

Red snapper is a delicious fish you can cook in a variety of ways, but one of the best ways to cook snapper is to throw it on the grill. You can also purchase snapper in filets or whole, although grilling a whole fish may seem intimidating at first.

Much like grouper, snapper is a mild-flavored fish that goes well with different sauces and marinades. One of the issues, however, is that snapper has become more of an umbrella term for white fish. Other types of white fish are often mislabeled as snapper, and this has led to price increases in many cases.

Snapper is full of healthy omega-3 fatty acids, but like most other fish, it’s important to consider the amount of mercury in red snapper. Although snapper does have less mercury than grouper, and it's normally safe to eat once or twice a week.
