Teleostei (teleosts) > Perciformes/Percoidei (Perchs) > Percidae (Perches) > Etheostomatinae
Etymology: Etheostoma: Greek, etheo = to strain + Greek, stoma = mouth; Rafinesque said "various mouths", but Jordan and Evermann suggest the name might have been intended as "Heterostoma (Ref. 45335); olivaceum: olivaceum refers to the coloration (Ref. 10294).

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 5723); common length : 5.0 cm TL male/unsexed; (Ref. 12193); max. reported age: 2.00 years (Ref. 12193)

Inhabit rocky pools and nearby riffles of headwaters and creeks (Ref. 5723); also found in streams (Ref. 10294). Often found in very shallow water less than 4 m deep (Ref. 5723). Juveniles feed on midge larvae and microcrustaceans; adults on midge larvae, other immature aquatic insects (mayflies, caddisflies, stoneflies), isopods and amphipods (Ref. 10294). Eggs are found clustered on underside of stone and guarded by males (Ref. 7043).

Eggs are found clustered on underside of stone (Ref. 7043). Males guard the eggs (Ref. 7043).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00301 - 0.01516), b=3.12 (2.94 - 3.30), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (tmax=2).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
