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); blennioides: blennioides meaning blenny-like (Ref. 10294).

Maturity: L_m ? range ? - ? cm
Max length : 17.0 cm TL male/unsexed; (Ref. 5723); common length : 5.5 cm TL male/unsexed; (Ref. 12193); max. reported age: 5 years (Ref. 12193)

Inhabit rocky riffles of creeks and small to medium rivers, and shores of large lakes (Ref. 5723, 10294). Juveniles feed on midge larvae and microcrustaceans; adults consume midge larvae, blackfly larvae, and other immature aquatic insects, primarily mayflies and caddisflies (Ref. 10294). Distinct pairing during breeding (Ref. 36980). Eggs are found attached to the substrate unguarded (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=0.00741 (0.00426 - 0.01291), b=3.14 (2.99 - 3.29), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=5; Fec=404-1,832).

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