Short description Morfologia | Morfometria

Spine dorsali (totale): 13; Raggi dorsali molli (totale): 10; Spine anali 7; Raggi anali molli: 9; Vertebre: 23. Fish looks black apart from the bright yellow pectoral fins; `vertical' margin of soft portion of dorsal fin and trailing edge of caudal fin orange. Preopercular angle 110°-111°; strong overlapping scales cover cheeks; 8-12 rows deep below center of orbit. Fully scaled midline of thorax. A very short tube, slightly taller posteriorly supports the anterior nostril opening. Caudal fin slightly incised.

Prefers areas of staghorn or fire corals, or around rubble mounds composed of plate and staghorn corals. Subadults and adults in pairs, juveniles probably form schools. Feeds on seaweeds. Marketed fresh (Ref. 9813).

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=0.01445 (0.00650 - 0.03213), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 54.2 [27.2, 133.8] mg/100g; Iron = 0.831 [0.390, 1.936] mg/100g; Protein = 18.5 [17.0, 20.0] %; Omega3 = 0.1 [0.1, 0.2] g/100g; Selenium = 20 [8, 49] μg/100g; VitaminA = 31.5 [7.3, 130.7] μg/100g; Zinc = 1.65 [0.64, 3.54] mg/100g (wet weight);
