Redear Sunfish

Redear Sunfish are an introduced species in Arizona that have established thriving populations, particularly in the lower Colorado River system.

Scientific Name: Lepomis microlophus

Also known as shellcrackers, cherry gills, sun perch


Physical Characteristics:
  • These fish closely resemble bluegill but are distinguished by their larger size, red or orange margin on the opercular flap (gill cover), and more elongated pectoral fins.
  • In Arizona waters, redear can reach impressive sizes - Lake Havasu holds the world record at 6 pounds 4 ounces, caught in 2021, with the lake consistently producing fish over 4-5 pounds annually.

Redear Sunfish FAQ

Answers from onWater's species guide.

What are the best lures and bait for Redear Sunfish in Arizona?

Natural baits significantly outperform artificials - nightcrawlers are considered the top choice, along with mealworms, crickets, and small pieces of earthworms.

When is the best time to fish for Redear Sunfish in Arizona?

The optimal fishing season for redear sunfish in Arizona runs from March through May during their spawning period, with ideal water temperatures between 72-75°F at Lake Havasu. However, they can be caught year-round, including during winter months when the previous world record was taken in February.

How do you catch Redear Sunfish in Arizona?

Fish these baits on dropshot rigs similar to bass fishing setups. Soak baits stationary for extended periods (up to 10 minutes) rather than using moving presentations, as redear prefer motionless offerings. Make long casts of 100+ feet in Havasu's clear water.

What do Redear Sunfish eat?

Their diet consists primarily of mollusks including snails and mussels - earning their 'shellcracker' nickname - along with ostracods, hydrobiid snails, zooplankton, amphipods, chironomid larvae, cladocerans, aquatic insects, crayfish, and small fish.
