Short description Chiavi di identificazione | Morfologia | Morfometria

This species is distinguished from G. oelemariensis subgenus Oelemaria) by possessing 2 supraneural bones and a midlateral bar and a midlateral spot (vs. absence of a midlateral bar in G. oelemariensis). G. stergiosi is distinguished from all other species in the subgenus Guianacara by possessing of a round midlateral spot placed almost entirely below the upper lateral line, and representing the darkest area in the midlateral bar (the upper lateral line is in contact with the upper fifth of the round midlateral spot; midlateral bar progressively fades, and the midlateral spot becomes darker in all but small juvenile specimens) (Ref. 57436).

Inhabits moderately shallow, clear-black, acid waters with slow to moderate currents on rocky bottoms (Ref. 57436).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01862 (0.00849 - 0.04084), b=3.01 (2.83 - 3.19), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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