Краткое описание
морфология | морфометрия
колючие лучи спинного плавника (общее число): 14 - 18; членистые (мягкие) лучи спинного плавника (общее число): 14-17; членистые (мягкие) лучи анального плавника: 11 - 13. Percina apina can be distinguished by having the following characters: dorsum with about 11 dark saddles that are interspersed with vermiculated patches of pigment that extend to the side of the body; 7 to 9 dark, large round or oval shaped lateral blotches along the side of the body that are typically wider than high; anterior-most blotches are just posterior of the operculum and are smaller in size, as is the most posterior blotch, which is often confluent with a distinct caudal spot; a moderate to diffuse suborbital bar of pigment; males in nuptial condition with a gold-green background color with an overall duskiness and a blue-green iridescence on the cheeks and side of the body; first dorsal fin with an intense orange submarginal band distal to a narrow yellow band of coloration with a wide and basal band comprising uniform streaks of brown-orange pigment; distal margin of the second dorsal fin lightly pigmented with a proximate band of dusky orange coloration and a tessellated basal margin; caudal fin with light bands of pigment and the distal margin slightly pigmented in nuptial males; nuptial males with anal fin yellowgold distally with a basal peppering of dark pigment; males in nuptial condition with membranes of the pelvic fin filled with jet-black pigment, and the pectoral fin membranes slightly peppered with dark pigment (Ref. 116752).
Habitats of this species differ between reproductive and non-reproductive periods. Both sexes in in reproductive condition were most often found in swift runs of depths about one meter or less with predominant gravel and cobble substrates. On many occasions, adult males were collected in shallow, swift riffles with gravel bottoms during late April to early June. In summer months, adult males and females occurred in swift runs and in pool areas with substrates free of silt. Subadults were only encountered in pool habitats and were usually accompanied by adult females (Ref. 116752).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
