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 both sunfish 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 Redbreast Sunfish: Habitats, Size, Weight and Appearance
How can you tell the difference between the two fish?
To tell the difference between a bluegill and a redbreast sunfish compare their gill ear flap, dorsal fin, head coloring and body shape. Redbreast’s ear flap is elongated compared to the shorter, rounder ear flap of the bluegill. Bluegill have a dark spot at the dorsal fin base the redbreast doesn’t have. Bluegill have blue coloring on the cheeks and gills compared to reddish orange on the bluegill. The bluegill’s body is rounder than redbreasts.
Redbreast sunfish reddish orange belly color extends further down towards the anal fin. The bluegill’s reddish orange belly coloring is more towards the front than rear.
Redbreast sunfish have teeth on the roof of the mouth. Bluegill’s mouth roof doesn’t have teeth.

Redbreast sunfish taste similar to bluegill and has a mild to sweet taste. Both sunfish have a firm, flakey texture.
Redbreast sunfish tastes good to most people and has a mild to sweet taste. The white flesh is flakey and slightly firm.
Depending on the time of year or type of water, both sunfish can taste slight muddy or fishy to some people. The fish can be soaked in milk to help eliminate any unpleasant taste or odor.
- 61% said they preferred bluegill.
- 30% said they preferred redbreast.
- 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 blue sunfish
When preparing recipes for dinner it’s not always possible to locate the type of fish in a store or find it while fishing. If you have one sunfish, you may ask, can I substitute one for the other?
Redbreast sunfish and bluegill can substitute for each other due to their similar tastes and textures. Both sunfish can be used in many of the same recipes and cooking methods. They both can be cooked by baking, broiling, steaming, grilling and pan frying.

Bluegill and Redbreast 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 1. 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 sunfishhas more mercury?
Redbreast sunfish and bluegills have similar levels of mercury. Both sunfish 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, sunfish 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 prior to fishing for sunfish 2.
The costs for sunfish will vary depending on how they were caught fishing and where they’re sold. When purchasing any fish, be sure to check the label. Therefore, which sunfish is more expensive?

Both sunfish are an excellent source of healthy fats, protein, B vitamins and minerals. Both sunfish contain the following:
- Omega-3 fatty acids
The following number of nutrients per four raw ounces of bluegill fish:
|Bluegill, raw (4 Ounces)
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.
Since the sunfish are difficult to locate in stores, I’ll consume either fish available to me for their nutrient content, taste and health benefits.
Redbreast Sunfish and Bluegill 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 5.
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.
The B vitamins provided by sunfish include B1 (thiamin), B2 (riboflavin), B3 (niacin), B9 (folate) B6, B12 and B5. B vitamins help support the following:
- 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 6.
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 7.
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.
Both sunfish 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 8.
Calcium also helps the following:
- Muscles need calcium to function properly.
- Improve nerve function.
- Build and maintain strong bones.
The potassium provided helps the body get rid of excess sodium which helps reduce fluid build-up. These help keep systolic and diastolic blood pressure lower 9.
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 10.
According to Harvard Health, a number of studies have shown a connection between low potassium levels and increased blood pressure 11.
There are 14.2 mcg of selenium per four ounces of either sunfish. I’m unsure why many don’t write about it more because studies 12 show selenium may help to protect the following:
- The immune system
- Cognitive issues
- Heart disease
Both sunfish 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.
As a Certified Health Coach many of my clients ask me about seafood. In addition to educating my Health Coaching clients about redbreast and bluegill, I have researched, purchased and consumed both fish for 20 years prior to, during and after writing this article.
