Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 7; Rückenflossenweichstrahlen (insgesamt): 8-9; Afterflossenstacheln 1; Afterflossenweichstrahlen: 8 - 9. This species is placed under Hyrcanogobius on the basis of slightly different organization of cephalic sensory pores (Ref. 59043).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

This near-pelagic coastal marine species is found in areas with different salinities, including freshwater. It lives for a year and matures at 18-20 mm SL. Spawns after first winter, May-June, down to 2-7 m, with females probably laying 2-3 portions of eggs (0.4-1.0 mm), separately attached inside a mollusc shell; and adults dying soon after spawning. Feeds on small crustaceans (Ref. 59043).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00349 - 0.02862), b=3.09 (2.85 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (tm=1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
