Eponymy: Professor Johann Krynicki (1797–1838) was a Polish entomologist who was a Professor at Kharkov University in the Ukraine, where his collection is housed. A bird is also named after him. (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Can be diagnosed from its congeners in Europe by the possession of the following unique characters: caudal emarginate; no processus dentiformis; and dorsal fin with 7½ branched rays. Can be further distinguished by its caudal peduncle depth 2.1-2.4 times in its length, 2.0-2.5 times in body depth (Ref. 59043).

Occurs in the upper montane reaches of rivers. Scarce but possibly overlooked (Ref. 59043).

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=0.00741 (0.00354 - 0.01554), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
