Bluegill (Lepomis macrochirus) is a freshwater fish specie belonging to the Sunfish family native to North America. It’s pretty popular for cooking due to its firm and mild meat. Moreover, it’s also available in abundance in the US and the neighboring countries. You may hear people call it with other names, like bream or coppernose.

Bluegill has a deep-bodied appearance like that of a panfish. It consists of a long dorsal fin, along with a small mouth. However, the unique feature of bluegill is its dark ear covering. Additionally, its dorsal fin consists of a distinctive dark spot.

Note that the body color of bluegill is highly dependent on its age and habitat. Typically, it is green or dark olive.

Sunfish isn’t mainly a type of fish. Instead, it signifies a family, also known as Centrarchidae, of almost 34 fish species. Some of the popular sunfish include:

  • Smallmouth Bass
  • Largemouth Bass
  • Black Crappie
  • Bluegill
  • Rock bass
  • Green Sunfish

Most sunfish have a familiar look. They have a deep body with a laterally compressed appearance, making them look like round pancakes. But, keep in mind that the colors may differ due to the habit and specie type.

All species in the sunfish family, including bluegill, reside in freshwater only.

What are the substitutes for Sunfish?

Differences Between Bluegill and Sunfish

Now, let’s cover the differences between bluegill and sunfish in detail.

1. Terminology

The most significant difference between bluegill and sunfish lies in the terminology. Bluegill stands for one particular freshwater fish. On the other hand, sunfish stands for a group of freshwater fish belonging to the same family, Centrarchidae.

Additionally, the bluegill is a part of the sunfish family. Therefore, all bluegill are a type of sunfish. However, the sunfish family contains several other freshwater fish species. So, all sunfish are not necessarily bluegill.

2. Taste and Texture

Bluegill has a similar taste and texture to that of other sunfish. The meat is firm, mild, clean, and definitely more non-fishy than other table fish. Yet, there are slight differences when compared to other popular sunfish, like bass or crappie.

  • Largemouth bass has a fishier taste compared to bluegill and smallmouth bass.
  • Black crappie containing red flesh has a very intense fishy flavor sometimes. The meat is also not as firm as that of bluegill.
  • Green sunfish has a fishier taste and less firm texture when compared to bluegill.

Therefore, bluegill and sunfish taste pretty similar, but the “fishy” taste might be more pronounced in other sunfish species.

3. Appearance

Fresh Caught Bluegill

All sunfish, including bluegill, have a standard deep body and pancake-like appearance. But, some features are specific to bluegill only.

For instance, bluegill contains a dark blotch or spot near the end of its dorsal fin. Additionally, it also has a dark ear covering. These features aren’t seen in other sunfish varieties, like bass or pumpkinseed.

4. Nutrient and Mercury Content

If you check the nutrient content of bluegill and sunfish, it’s almost similar. It’s because bluegill is a type of sunfish itself. However, slight variations are typically observed between different species of sunfish.

For instance, largemouth bass contains 0.6 gm of Omega 3 Acid compared to 0.16 gm of it in bluegill. So, it is more nutrient-rich than bluegill. Similarly, black crappie also has more Omega 3 Acid (0.29 g) than bluegill.

However, the fat content of bluegill (0.8 grams) is lesser than that of both largemouth bass (4 grams) and black crappie (1.3 grams).
