Issue
There has been confusion between G. dembeensis, G. johnstonii and G. hindii. G. johnstonii is a junior synonym of G. dembeensis, but G. hindii differs in having a fully scaled predorsum, belly and chest; it does, however, share two important meristic and morphometric features with G. dembeensis: high number of scales in lateral line and vent located away from anal fin (Ref. 81639).

Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 10 - 11; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 9. Diagnosis: Garra dembeensis is distinguished from African congeners by the following combination of features: well-developed disc; between 0 and 4 predorsal scales anterior to dorsal fin; asquamate chest, belly and postpelvic region; intestine of medium length; ad moderately sized gas bladder (Ref. 58532).

Commonly found in rapid parts of rivers and also on wave-washed rocky shores of Lake Victoria (Ref. 4903). Adheres to stones in swift water (Ref. 28714). Feeds on epilithic algae and lithophilic insects (Ref. 12526), scraped from the surface of rocks (Ref. 4903).

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=0.00759 (0.00331 - 0.01740), b=3.05 (2.88 - 3.22), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 2.0 ±0.00 se; based on food items.

Ελαστικότητα (Ref. 120179): Υψηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού < 15 μήνες (Preliminary K or Fecundity.).

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