Redear Sunfish

Redear Sunfish

Redear Sunfish are not native to California but have been widely introduced throughout the state since 1948.

They're now established in numerous drainages including the Sacramento-San Joaquin, Death Valley, Tulare-Buena Vista, Southern California regions, the Yolo Bypass, Suisun Marsh, and Colorado River systems.

Scientific Name: Lepomis microlophus

Also known as shellcrackers

Physical Characteristics:
  • These deep-bodied panfish are distinguished by their red or orange opercular flap margin (brighter red in males, orange in females), long pointed pectoral fins, and olive-green coloration with pale mottled brown to silver sides.
  • They can grow substantially larger than bluegill.

What to know

Habitat Distribution

  • They prefer deeper waters (at least 2 meters) of warm, quiet ponds and lakes with substantial aquatic vegetation, avoiding turbid or shallow water.

Key Locations

  • Clear Lake in Lake County is a prime destination, known for excellent redear populations alongside bluegill and bass.

Specific Spots

  • Look for them in deeper waters of warm, quiet lakes and ponds with aquatic vegetation, particularly around structures like laydown trees, cypress trees, dock posts, stumps, and woody debris where snails congregate.
  • Target depths of 3+ feet, focusing on colony spawning areas near vegetation and hard cover.
  • Focus on areas with visible shell debris on bottom, indicating good snail populations.
  • Post-spawn periods can be productive around humps with stumps leading to deeper water.

Redear Sunfish FAQ

Answers from onWater's species guide.

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

Natural baits significantly outperform artificials - use small pieces of worms, crickets, grass shrimp, and cut bait. Small jigs tipped with live bait can be effective.

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

Spring through early summer provides the best fishing, with spawning season April-August depending on water temperature. In summer, target deeper structure (10-20 feet) as they move from shallow spawning areas.

How do you catch Redear Sunfish in California?

Use simple rigs with small hooks and minimal weight, letting baits sink to bottom structure. Small jigs tipped with live bait can be effective. Bobber rigs work well around laydown trees and cypress stands, allowing precise bait placement in openings.

What do Redear Sunfish eat?

Redear sunfish are specialized mollusk feeders, earning their 'shellcracker' nickname from their ability to crush snails and clams with powerful pharyngeal teeth.

Where do Redear Sunfish live in California?

They prefer deeper waters (at least 2 meters) of warm, quiet ponds and lakes with substantial aquatic vegetation, avoiding turbid or shallow water.
