Redeye Bass

The Redeye Bass is a small member of the black bass genus Micropterus, native to cool, rocky streams of the Coosa, Tallapoosa, and Savannah river systems in the southeastern United States Appalachian foothills. It is one of the smallest black bass species, rarely exceeding 30 cm, and is closely tied to clear, flowing upland waters rather than lakes or reservoirs. Redeye Bass populations have declined in parts of their range due to habitat alteration and hybridization with introduced Alabama and spotted bass, prompting conservation concern for genetically pure populations in isolated headwater streams.

Redeye Bass are slender and elongated with olive-bronze backs fading to a pale belly, and faint, irregular dark blotches along the midline that may form a broken lateral band.

• Bright red or orange eyes, the source of the common name
• Dark bar extending through the eye
• White or pale margins on the tips of the tail and sometimes the dorsal and anal fins
• Small mouth relative to other black bass, rarely reaching the rear of the eye
• Generally smaller than largemouth or spotted bass, typically 20-30 cm

Redeye Bass inhabit clear, cool, fast-flowing rocky streams and small rivers in the upland Piedmont and Appalachian foothill regions of Georgia, Alabama, and South Carolina, primarily within the Coosa, Tallapoosa, and Savannah river drainages. They favor pool-and-riffle stream habitats with boulder, gravel, or bedrock substrate and moderate to swift current, avoiding warm, sluggish, or heavily silted water found lower in these same watersheds. Their restriction to headwater and mid-order stream reaches makes them especially sensitive to impoundment, siltation, and warming water temperatures.

Redeye Bass are opportunistic stream predators that feed on aquatic insects, crayfish, and small fish, often holding position behind rocks in current to ambush drifting prey. They are solitary and territorial, defending favored lies within pools and runs. Spawning occurs in spring as water warms, with males building simple nests in gravel or sand along stream margins and guarding eggs and fry. Their strong association with flowing, well-oxygenated upland streams ties their population health closely to watershed condition and stream connectivity.
