† Populations may not be currently present.
Ecology: Inhabits streams with sandy bottoms and moderate to swift currents (Williams 1975). Spawning occurs from April-August, with maturity reached by 38 (females) to 43 (males) mm SL (Williams 1975; Heins 1985). Maximum life span of approximately 3 years (Heins 1985).
Means of Introduction: The introduction of the Florida Sand Darter was most likely via a bait bucket (Gilbert and J. D. Williams, unpublished data). While this highly translucent darter may not be used for bait, it easily may have been taken as by-catch by anglers seining for bait. It is common in streams of the Choctawhatchee River drainage, just west of the Apalachicola River, and anyone seining for bait minnows in streams with sandy bottom pools may have captured Florida Sand Darters.
Status: Established in Florida. Many more collections of Florida Sand Darter have been reported since the original two reports. The species is now thought to be fairly common in the Apalachicola River (Gilbert and J. D. Williams, personal communication).
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
