Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 6 - 7; Raggi dorsali molli (totale) : 27 - 30; Spine anali: 2; Raggi anali molli: 28 - 31. Bluish grey to grey-brown, capable of displaying a colour pattern of vertically elongate blotches (lighter or darker than ground colour) on side and upper part of body. Opercular and preopercular margins not dark brown. Caudal fin uniform in colour. Gill rakers on lower limb of gill arches entirely pale. Edge of lower lip not white (Ref 9808).

Benthopelagic over coral and rock (Ref. 58302). Occurs singly or in aggregations along clear seaward and outer lagoon reefs and channels (Ref. 37816). Feeds in midwater on zooplankton (Ref. 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 28.8, mean 26.5 °C (based on 82 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.3 ±0.1 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 40.2 [24.4, 76.9] mg/100g; Iron = 0.566 [0.291, 0.972] mg/100g; Protein = 18.6 [17.4, 19.7] %; Omega3 = 0.123 [0.078, 0.227] g/100g; Selenium = 35.6 [18.7, 63.5] μg/100g; VitaminA = 56.6 [17.3, 183.1] μg/100g; Zinc = 1.54 [1.05, 2.21] mg/100g (wet weight);
