Bluegill vs Redear Sunfish – Are They The Same? We Compare


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 between a bluegill and a redear sunfish?

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 redear sunfish doesn’t have.

Another way to tell the difference between a bluegill and redear is to check inside their throats. Redear sunfish have teeth inside their throat. Bluegills don’t have any teeth. 

Redear sunfish 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 redear sunfish has a golden yellow color with brown spots.

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 consumed 12. 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, does redear sunfish or bluegill have more mercury?

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 for the current recommendations 13.

Redear Sunfish and Bluegill Health Benefits

Omega 3 Fatty Acids

The omega-3 fatty acids contained in redear sunfish and bluegill 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 16.

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.

Magnesium

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 17.

Magnesium helps keep blood pressure levels balanced and stable. A recent study researched 22 studies and concluded magnesium supplementation decreased diastolic and systolic blood pressure 18.

The magnesium in redear and bluegill 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

Potassium provided by redear and bluegill 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 19.

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 water 20.

According to Harvard Health, a number of studies have shown a connection between low potassium levels and increased blood pressure 21.

Phosphorus

Redear sunfish and bluegill 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.

Selenium

There are 14.2 mcg of selenium per four ounces of redear sunfish and bluegill. I’m unsure why many don’t write about it more because studies 22 show selenium may help to protect the following:

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