Bluegill vs Redbreast Sunfish – What’s The Difference?

Bluegill and redbreast sunfish have many similarities. For this reason many people wonder about their differences. Therefore, let’s answer, are redbreast sunfish and bluegills the same?

Redbreast sunfish and bluegill are different species of fish although they are from the same family. Bluegill is the L. macrochirus species and redbreast sunfish is the L. auritus species. The most identifiable difference is the longer gill ear flap of the redbreast sunfish compared to the shorter bluegill flap.

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.

Nutrient Resources 14 15

Both sunfish provide almost an equal number of the same nutrients. Keep reading the next section below to find out how the nutrients are beneficial, especially omega-3s.  

Redbreast Sunfish and Bluegill Health Benefits

Omega 3 Fatty Acids

The omega-3 fatty acids contained in redbreast 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.

B Vitamins

The B vitamins provided by redbreast sunfish and bluegill 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.


Both sunfish 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.

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.


Redbreast sunfish and bluegill provide approximately 90 mg of calcium per four ounces. Calcium is important for blood pressure and the heart. Harvard Health reports calcium helps maintain blood pressure because it helps to control the relaxing and tightening of blood vessels 19.

Calcium also helps the following:

  • Muscles need calcium to function properly.
  • Improve nerve function.
  • Build and maintain strong bones.


Potassium provided by redbreast and bluegill helps the body get rid of excess sodium which helps reduce fluid build-up. These help keep systolic and diastolic blood pressure lower 20.

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 21.

According to Harvard Health, a number of studies have shown a connection between low potassium levels and increased blood pressure 22.


There are 14.2 mcg of selenium per four ounces of redbreast sunfish and bluegill. I’m unsure why many don’t write about it more because studies 23 show selenium may help to protect the following:

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


Redbreast 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.
