Short description Morphology | Morphometrics

Dorsal spines (total): 6 - 8; Dorsal soft rays (total): 15-18; Anal spines: 0; Anal soft rays: 10 - 13; Vertebrae: 31 - 34. Caudal fin with 13 to 14 rays (Ref. 40476).

Biology     Glossary (e.g. 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).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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

Phylogenetic diversity index (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).
Trophic level (Ref. 69278):  3.2   ±0.2 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=1-3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
