Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи анального плавника: 11 - 14. Can be distinguished from other species of Cottus in Europe by possessing a shallow transverse groove in the snout between the anterior and posterior nares and the combination of the following characters: genital papilla lobular in males; depth of caudal peduncle 20-24% HL; length of caudal peduncle 41-64% HL; prickling on body extending backwards to caudal peduncle (reduced or sometimes absent in some populations); absence of distinct transverse bands on pelvic fin; predorsal length 32-37% SL; distance from tip of snout to origin of second dorsal fin 50-52% SL; dorsal head length 21-25% SL; unique molecular markers (Ref. 55856).
Inhabits small streams to medium-sized rivers. Feeds on a wide variety of benthic invertebrates. Females spawn once a year (Ref. 59043).

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=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 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).
