Southern Redbelly Dace
Chrosomus erythrogaster
Southern Redbelly Dace is a small North American minnow found in cool, clear headwaters and spring-fed creeks. Males develop a vivid red belly and often spawning tubercles; it is mostly of interest to bait collectors and naturalists rather than as a target game fish.
Speckled Dace
Rhinichthys osculus
Speckled Dace is a small western North American minnow with many local forms. It lives in clear, shallow streams and spring-fed waters, where it forages on tiny aquatic insects and algae.
Spotfin Shiner
Cyprinella spiloptera
The spotfin shiner is a small North American minnow found in clear to moderately turbid streams and rivers, often over sand, gravel, or riffles. Males develop a dark spot on the dorsal fin and can show blue-green sheen during spawning.
Spotted Bass
Micropterus punctulatus
Spotted Bass is a black bass native to the southeastern United States, now widely introduced elsewhere. It favors clear to moderately turbid water and often overlaps with largemouth and smallmouth bass, but usually stays more offshore or current-oriented than largemouths.
Spotted Gar
Lepisosteus oculatus
Spotted Gar is a long, narrow North American gar with a spotted body and sharp tooth-filled snout. It lives in slow, shallow freshwater and is an ambush predator that often lurks among weeds and submerged cover.
Spotted Sunfish

Spotted Tilapia
Pelmatolapia mariae
Spotted Tilapia (Pelmatolapia mariae) is a hardy African cichlid widely introduced outside its native range and often established in warm freshwater canals, ponds, and slow rivers. It is a nest-building omnivore that can be caught on small natural baits and light tackle where populations are legal to target.
Stone Loach
Barbatula barbatula
Stone loach (Barbatula barbatula) is a small, bottom-dwelling Eurasian loach of clear, cool streams and rivers. It hides under stones by day and feeds mostly at night on aquatic invertebrates and small benthic prey.
Stonecat
Noturus flavus
Stonecat (Noturus flavus) is a small native North American madtom, a nocturnal catfish that hides by day under rocks and logs in flowing streams and rivers. It’s known for a stout body, broad head, and venomous pectoral and dorsal fin spines.
Streaked Prochilod
Prochilodus lineatus
Streaked Prochilod (Prochilodus lineatus) is a South American characin-like migratory fish that forms large schools and is important in river fisheries. It is a detritivore-grazer, often abundant in big lowland river systems and floodplains.
Striped Shiner
Luxilus chrysocephalus
Striped Shiner is a common North American minnow of clear upland streams and small rivers. It often schools over gravel and sand, feeding on insects, algae, and small invertebrates; it is sometimes used as bait but is not a major game fish.
Striped Snakehead
Channa striata
Striped snakehead (Channa striata) is a hardy air-breathing predatory fish native to South and Southeast Asia and widely introduced elsewhere. It inhabits warm, still or slow waters and can survive poor oxygen conditions. In many regions it is an invasive species and a valued food fish.
