Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 6 - 8; Rückenflossenweichstrahlen (insgesamt) : 8 - 9; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 7 - 8; Wirbelzahl: 26. Rhinogobius sangenloensis is distinguished from all other congeners by the unique combination of following characters: modally I/8 second dorsal-fin rays; I/7-8 anal-fin rays; modally 17 pectoral-fin rays; 25-27 longitudinal scales; 9-11 predorsal scales; 10 + 16 = 26 vertebrae; 3-4 longitudinal, discontinuous orange to brown or brownish black bars and stripes on the body; 2 basal grayish black spots on cheek; 2 oblong black bars on pectoral-fin base in male; an orange mark on lower 1/3 region of caudal fin in male (Ref. 94987).

Occurs preferably in a hill-stream habitat with moderate to slow current over small to medium-sized pebbles and water depth ranging from 15-70 cm (Ref. 94987).

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=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±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).
