Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 8; Rückenflossenweichstrahlen (insgesamt) : 16; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 14. This species is distinguished by having the following set of characters: fully scaled breast; naked cheek; anteroventral profile of lower jaw is almost straight; a distinct, jet-black blotch distally on the spinous dorsal fin (Ref. 74926).

Found on shallow waters near the bottom. Young enter brackish waters (Ref. 4833). Feeds mainly on small crustaceans, foraminiferans and nematodes. Sold fresh and dried salted in markets, also used for fishmeal.

Estimates based on models

Preferred temperature (Ref. 123201): 27.2 - 29.1, mean 28.5 °C (based on 844 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01202 (0.00693 - 0.02085), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.29 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (K=1.18).

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

Preiskategorie (Ref. 80766): High.
