Teleostei (teleosts) > Perciformes/Percoidei (Perchs) > Percidae (Perches) > Percinae
Etymology: Crystallaria: Latin, cristallum = ice (Ref. 45335); cincotta: Named for Daniel A. Cincotta, for his devotion toward studies of fish diversity of West Virginia, including efforts toward conservation of the Elk River drainage and its diverse ichthyofauna.
Eponymy: Daniel Anthony ‘Dan’ Cincotta (d: 1952) is Adjunct Assistant Professor of Ichthyology at West Virginia University (2005–2018) (where Stuart Welsh is an assistant professor), and the Senior Ichthyologist with the Wildlife Diversity Unit of West [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11 - 13; Dorsal soft rays (total): 11 - 15; Anal soft rays: 11 - 13. Distinguished from populations of Crystallaria asprella of the Gulf Coast, Mississippi River and Wabash River by a combination of the following features: gape width larger approximately equal to or exceeding the inter-pelvic fin base width; a preorbital blotch distinctly separate from the anterior orbital rim; pelvic fins distinctly falcate in both sexes; cheek scale rows reduced (modally 2); opercle scale rows reduced (modally 2); number of midlateral blotches higher (modally 13); number of anal-fin rays lower (modally 13); number of dorsal-fin spines lower (modally 12); and scales below the lateral line higher (modally 11) (Ref. 74948).
Body shape (shape guide): elongated.

Biology     Glossary (e.g. epibenthic)

Found mostly in waters with moderate flows over a sand, gravel and cobble mix of benthic substrate within the lower sections of riffles or upper parts of pools (Ref. 75199). Migratory behaviour is undetermined (Ref. 126106).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
