Common names: Chornaya tubenose goby
Occurrence: native
Salinity: freshwater
Abundance: | Ref:
Importance: | Ref:
Aquaculture: | Ref:
Regulations: | Ref:
Uses: no uses
Comments: Found only in the catchment of the River Chornaya whose estuary is located on the south-western coast of Crimea (Black Sea basin) (Ref. 75105). During summer, only about 10 km of habitat in the middle portion of Chornaya are left; water in the lower part is extracted in large quantities for irrigation, making this medium-sized stream almost dry in summer. Thus, this fish is likely to become extinct in the near future due to increasing water abstraction (Ref. 75105).

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Afterflossenweichstrahlen: 15 - 18. Distinguished from all congeners by having 45-54+2-3 scales in midlateral series; nuptial males with hump behind eye; head length 26-29% SL; anal fin with 15-17½ rays, mode 17½ ; second dorsal fin with 18-19½ rays, mode 18½ (Ref. 75105).

Occurs in moderately fast flowing and stagnant portions of medium-sized stream (Ref. 75105); flow of about 10 m3/s.. No data on biology known so far. It is still abundant in a very limited stretch of stream (about 25 km long), but s declining, if water abstraction (large quantities extracted for irrigation) intensifies, the whole stream might dry in summer (Ref. 59043).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), 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

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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