Bluegill vs Redear Sunfish – What’s the Difference? Panfish

Bluegill and redear sunfish are very similar. For this reason many people wonder if they’re the same or differences. Therefore, let’s answer, is a redear sunfish the same as a bluegill?

Redear sunfish and bluegill are different species of fish although they are from the same family. Redear sunfish is the L. microlophus and bluegill is the L. macrochirus species. The most identifiable difference is the redear’s operculum has a bright red edge compared to the bluegill which is all black. 

This article will compare their tastes, textures, cooking methods, costs, mercury levels and whether one can substitute for the other in recipes. In addition, I’ll do a side-by-side comparison of their habitats, appearance and compare their nutritional value.

Bluegill vs Redear Sunfish: Habitats, Size, Weight and Appearance

How can you tell the difference?

The best way to tell the difference between a bluegill and a redear sunfish is to check their operculum (gill ears). The bluegill’s operculum is completely black. The redear’s operculum is black with a bright red edge. Bluegill has a black spot on the dorsal fin base which redears doesn’t have.

Another way to tell the difference is to check inside their throats. Redears have teeth inside their throat. Bluegills don’t have any teeth.

Redears have brown spots speckled on the sides of their body with faint black bars. Bluegill doesn’t have any brown spots and their black bars are darker and more prominent.

Bluegill have bright blue coloring on their cheeks and chin while redears have a golden yellow color with brown spots.

Bluegill and Redear Sunfish Scientific Classifications, Families, Species

Bluegill are from:

  • Family: Centrarchidae
  • Genus: Lepomis

Sunfish: Tastes and Textures

One of the most important things people takes into consideration when choosing a fish is its taste. When comparing the two fish, bluegill vs redear sunfish, does one taste like the other?

Redear sunfish taste similar to bluegill and has a mild to sweet taste. Both fish have a firm, flakey texture. 

Redear sunfish tastes good and is pleasing to most people having a mild to sweet taste. The white flesh is slightly firm and flakey.

Depending on the time of year or type of water, both of them may taste slight muddy or fishy to some people. The fish can be soaked in milk to help eliminate any unpleasant taste or odor.

To conduct original research, I polled clients, members of food groups and readers. I asked them which fish taste better?

  • 59% said they preferred bluegill.
  • 32% said they preferred redear.
  • 9% said they had no preference.

To conduct more research, I set up a taste test at home. Both fish were cooked and seasoned the exact way. 75% said they preferred the bluegill.

Bluegill and Redear Sunfish Mercury Levels

The EPA and The FDA have issued suggestions and warnings about mercury levels in fish and how often they should be consumed1. This is especially important for young infants, pregnant women and developing children.

They established three lists. Best fish, good choices and ones to avoid based on their mercury levels. Therefore, which one has more mercury?

Redear sunfish and bluegill have similar levels of mercury. Both are listed on the FDA’s best choice of fish regarding mercury levels. 

If you’re pregnant, breast feeding or has a young child, Always check with a physician prior to eating new foods or changing your dietary habits.

These mercury warnings can change over time or affect only a particular area or state. Please check with your local EPA and FDA, especially when fishing, for the current recommendations2.

Redear Sunfish and Bluegills Health Benefits

Omega 3 Fatty Acids

The omega-3 fatty acids are heart healthy and help keep arteries healthy. The omega-3s may help with the following:

  • Reduce inflammation.
  • Reduce plaque buildup.
  • Keeping bad cholesterol low.
  • Keeping good cholesterol high.
  • Lowering triglycerides
  • Help keep the heart rhythms more normal.

DHA and EPA, two of the fatty acids, are associated with lowering blood pressure and improving the health of blood vessels ((National Center for Biotechnology: Marine Omega-3 Supplementation and Cardiovascular Disease)).

Studies suggest omega-3s can help reduce joint pain and stiffness in people with rheumatoid arthritis. They may also boost the effectiveness of anti-inflammatory drugs.

Both fish provide about 34 mg of magnesium per four ounces. It calms and relaxes the whole body including blood vessels. Magnesium has been shown to help improve sleep related problems like insomnia ((National Institutes of Health: Magnesium)).

Magnesium helps keep blood pressure levels balanced and stable. A recent study researched 22 studies and concluded magnesium supplementation decreased diastolic and systolic blood pressure5.

The magnesium helps control muscle and nerve function, blood sugar and blood pressure.

In the muscles and heart, magnesium competes with calcium to help the muscles relax after contracting. When the body is low in magnesium, calcium can over stimulate the heart muscle’s cells causing a rapid or irregular heartbeat.

B Vitamins

The B vitamins provided include B1 (thiamin), B2 (riboflavin), B3 (niacin), B9 (folate) B6, B12 and B5. B vitamins help support the following:

  • Digestion.
  • Brain function.
  • Energy levels.
  • Red blood cells.
  • Cardiovascular disease.
  • Nerve function.


Potassium provided is approximately 400 mg. Potassium helps the body get rid of excess sodium which helps reduce fluid build-up. These help keep systolic and diastolic blood pressure lower ((American Heart Association: How Potassium Can Help Control High Blood Pressure)).

The more potassium you consume, the more sodium your body will lose. Consuming too much sodium or not enough potassium throws off the delicate balance the kidneys need to remove the excess water6.

According to Harvard Health, a number of studies have shown a connection between low potassium levels and increased blood pressure7.


Both fish provide approximately 203 mg of phosphorus per four ounces. It has been shown in scientific research to help with the following:

  • Promote healthy nerve conduction.
  • Aides the kidneys in waste removal.
  • Promote teeth and bone strength.
  • Muscle recovery after exercise.
  • Muscle contraction.
  • Help the body store and manage energy.


There are 14.2 mcg of selenium per four ounces. I’m unsure why many don’t write about it more because studies8 show selenium may help to protect the following:

  • The immune system
  • Thyroid
  • Cognitive issues
  • Heart disease
