Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 16 - 17; Dorsal soft rays (total): 10 - 12; Anal soft rays: 9. Diagnosis: yellow ocelli on anal fin of females and non-breeding males; juveniles and females with hyaline fins; breeding male without black markings in caudal fin (Ref. 57549). 10-16 gill rakers on first ceratobranchial (Ref. 57549), 4-5 on epibranchial (Ref. 27597). Teeth in outer rows on dentary and premaxilla of mature males small and bicuspid (Ref. 57549).

Forages in the water column, feeding mainly on zooplankton (Ref. 27597).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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