Barcheek Darter: Facts & Habitat

About Barcheek Darter

The barcheek darter (Etheostoma obeyense) is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is endemic to the eastern United States where it is only known to occur in the states of Kentucky and Tennessee in the Cumberland River drainage from the Big South Fork down to the Obey River. It is an inhabitant of smaller rivers, streams and creeks where it lives in small, rocky pools. This species can reach a length of 8.4 centimetres (3.3 in) TL though most only reach a length of 5 centimetres (2.0 in).

Diet and feeding

The FishTraits compilation records these diet categories for this species: invertebrates or larval fish. These are broad categories, not a claim that every individual consumes every example in a category.

Habitat preferences

Reported habitat associations include streams and small rivers, creeks.

The source records associations with sand, gravel, cobble, bedrock, organic debris. An association indicates reported use, rather than an exclusive requirement.

Reproduction and parental care

The compilation reports a representative maturity age of 2 years. Its maturity field summarizes mean, median, or modal estimates, usually for females; male estimates can be used when female data are unavailable. It is not a fixed age at which every fish first breeds.

Recorded spawning months are Apr, May, Jun for the source’s reporting region (TN). This is a regional calendar, not a range-wide schedule.

Size and recorded longevity

FishTraits reports a maximum total length of 8.5 centimetres. Some entries use an estimated asymptotic length; this value should not be treated as a certified record catch.

Range

Where it lives

81.9%of mapped records

Share of 524 GBIF observation records with a state location, across 2 states. The orange dots are USGS stream-survey sites where this species was caught.

A blank area on the dot layer usually means nobody sampled there, not that the fish is absent. Turn on “every survey site” to see where the survey looked.

Share of records by state

The USGS stream survey caught it at 25 of its sites, in 2 states. That survey and the GBIF records are two different counts of two different things, so the site keeps them apart.
