Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 8 - 11; Rayons mous dorsaux (Total) : 12; Épines anales: 0; Rayons mous anaux: 12. Head longer than body depth. Maxilla partly concealed, covered by lachrymal bone but extending to about hind margin of eye. Bristles on longest gill raker 105 on one side in specimens of 12.7 cm, 140 in 16 cm, and 160 in 19 cm fork length specimens. A black spot on body near lower margin of pectoral fin. Interpelvic process small and single. Swim bladder present. Anal spine rudimentary.

Adults occur in coastal bays, harbors and deep lagoons, usually in some turbid plankton-rich waters. Form schools. Feed on phytoplankton (diatoms) and small zooplankton (cladocerans, ostracods, larval polychaetes, etc.) (Ref. 9684). Small groups were seen eating eggs of Cheilio inermis straight after spawning (Ref. 48637). Adult individuals feed on macroplankton such as larval shrimps and fish. Eggs and larvae are pelagic (Ref. 6769). Generally marketed fresh, frozen, canned, dried-salted, and smoked; also made into fish sauce (Ref. 9684).

Estimates based on models

Preferred temperature (Ref. 115969): 23.7 - 28.3, mean 27.3 (based on 491 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00767 - 0.00989), b=3.07 (3.04 - 3.10), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.38 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.2-1.9; tm=0.5-1; tmax=4; Fec = 37,690).

Prior r = 0.62, 95% CL = 0.41 - 0.93, Based on 1 full stock assessment.

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (52 of 100).

Catégorie de prix (Ref. 80766): Very high.
