Blackstripe Topminnow
Fundulus notatus
The blackstripe topminnow is a small, slender fundulid native to interior North American waters, often associated with quiet, vegetated streams, sloughs, and backwaters. It is primarily an insect picker and surface feeder rather than a targeted sport fish.
Identification points
- Dark horizontal stripe running from the snout through the eye to the tail base
- Slim, cylindrical body with a small, terminal mouth
- Plain olive-brown back with lighter silvery sides and a subtle male fin tint in breeding condition
Habitat
Shallow, slow-moving or still freshwater habitats with dense submerged or emergent vegetation, including prairie streams, ditches, sloughs, oxbows, and backwaters; often near cover along margins.
Bait notes
Tiny live baits or natural offerings work best, such as small worms, insect larvae, and bits of maggot or crushed insect. Very small ճան lure or micro-jigs can take fish, but it is rarely pursued as a game species.
Behavior
Feeds at or near the surface on small aquatic and terrestrial insects, zooplankton, and tiny crustaceans. It is wary but school-oriented in calm water and tends to use vegetation and edge cover to avoid predators.
Caution
None notable for handling or consumption, but it is a small nongame fish and local regulations or collection limits may apply if you plan to keep it.
Fishing notes
Use ultra-light tackle and small hooks around shoreline vegetation, slack water, and creek margins. Present bait quietly under a float or with minimal disturbance; light line and short casts are usually more effective than active retrieves.
