Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 1 - 3; членистые (мягкие) лучи спинного плавника (общее число) : 35 - 38; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 17 - 20; позвонки: 46 - 49. Adults are brown to blackish along the sides, with variable mottled or blotched patterns bordered by yellow, and whitish ventrally (Ref. 33616).

биология     глоссарий (например epibenthic)

Occur in cool, clear streams with rocky bottoms in mountain terrain (Ref. 33616); with fast to moderate flow (Ref. 44894). Often abundant at altitudes of 200-700 m (Ref. 33616). Benthic, nocturnally active species which usually occur solitary. Juveniles often found in large groups among leaf litter and wood debris. Movements are restricted to a relatively small stretch of river over the duration of the life span. Occur with G. marmoratus at lower elevations, but they have different habitat preferences. Feed on insect larvae, fishes, fish eggs, earthworms and crustaceans. Breed between October and December. Sexual maturity is attained after 2 years (Ref. 44894). Often caught by recreational fishers targeting trout, although not a desirable target due to its small size (Ref. 33616).

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=0.01072 (0.00408 - 0.02815), b=3.01 (2.79 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.50 se; based on food items.
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Fec=120-320).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100).
