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).

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).

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).
