Short description Morphology | Morphometrics

Dorsal spines (total): 4; Dorsal soft rays (total): 27-28; Anal spines: 2; Anal soft rays: 17 - 18. Lunate caudal fin with elongated lobes in adults; yellowish green on head and dorsally on body, shading to light yellow ventrally; greenish yellow dorsal and anal fins, broad black stripe near dorsal fin base; caudal fin base and lobes greenish yellow with centroposterior part transparent with pale greenish yellow rays. Segmented caudal rays 11-12 (usually 11); lateral line terminating below 3rd to 7th dorsal soft rays (Ref. 54980).

Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 123201): 25.6 - 29.1, mean 28.1 °C (based on 91 cells).

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

Bayesian length-weight: a=0.00562 (0.00256 - 0.01233), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

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).

Nutrients (Ref. 124155): Calcium = 280 [141, 554] mg/100g ; Iron = 1.81 [1.08, 3.11] mg/100g ; Protein = 17.6 [16.6, 18.6] % ; Omega3 = 0.23 [0.12, 0.45] g/100g ; Selenium = 35.3 [15.4, 75.5] μg/100g ; VitaminA = 43.5 [13.7, 125.5] μg/100g ; Zinc = 2 [1, 3] mg/100g (wet weight);
