Biologia     Glossário (p.ex. epibenthic)

Occurs in cold, clear and fast-flowing water of small stream to medium-sized rivers as well as on gravel or rocky shores of cold lakes and in slightly brackish waters along eastern coast of Baltic coast (Ref. 59043). Feeds on small bottom invertebrates, mainly insects, crustaceans. Pink to yellow eggs are found in clumps attached to undersides of large stones (Ref. 41678). Contrary to statements in older literature, eggs and larvae of fishes are not a common food item (Ref. 45167).

Ciclo de vida ou comportamento de acasalamento Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

Spawns once a year for several years in low productivity streams, but exhibits multiple spawning within a season in high productivity environments (Ref. 40290, 40754). Male protects several batches of eggs--deposited below a stone--for about 3 weeks. Larvae are not guarded and may occasionally been eaten (Ref. 45166). Also Ref. 26506.

Estimates based on models

Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00543 - 0.01532), b=3.18 (3.03 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Nível Trófico (Ref. 69278):  3.2   ±0.2 se; based on diet studies.
Resiliência (Ref. 120179):  médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (tm=1-3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
