Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 9; Rückenflossenweichstrahlen (insgesamt) : 19 - 22; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 15 - 18. Diagnosis: Scutes on lateral line 23 (Ref. 57392) to 42 (Ref. 13442). No scales on chest (Ref. 13442), except a small mid-ventral patch in front of pelvic fins (Ref. 13442, 57392). Upper profile of head steep (Ref. 13442). Maxilla ending approximately below (Ref. 13442, 57392) or beyond (Ref. 57392) posterior edge of eye (in adult). Front of soft dorsal and anal fins elevated; olivaceous to bluish green dorsally, silvery to brassy on the sides; prominent black spot posteriorly on gill cover at level of eye, another at upper axil of pectoral fins, and often a third on lower pectoral rays; caudal yellowish (Ref. 13442).

Generally in neritic waters over the continental shelf (Ref. 5217), from the coastline, where it is common on shallow flats, to offshore waters (Ref. 57392). Adults ascend rivers (Ref. 26938). Juveniles abundant in brackish estuaries with muddy bottoms, near sandy beaches and on seagrass beds (Ref. 5217), entering lagoons and lower courses of rivers (Ref. 57392). They form fast-moving schools, although larger fish may be solitary. They feed on smaller fish, shrimp, and other invertebrates (Ref. 5521). Often grunts or croaks are heard when caught. Eggs are pelagic (Ref. 4233).

Estimates based on models

Preferred temperature (Ref. 115969): 16.5 - 27.9, mean 24.8 (based on 2020 cells).

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

Bayesian length-weight: a=0.01738 (0.01424 - 0.02121), b=2.94 (2.91 - 2.97), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.4 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Assuming tm 3-4).

Prior r = 0.53, 95% CL = 0.35 - 0.80, Based on 5 data-limited stock assessments.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).

Climate Vulnerability (Ref. 125649): High vulnerability (62 of 100).

Preiskategorie (Ref. 80766): Medium.
