Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found in estuaries (Ref. 75154). Usual habitat seems to be mangrove areas (Ref. 5222). Benthic (Ref. 75154). Forms large aggregations in shallow waters of river mouths and brackish mangrove regions throughout the year, prior to new moon (Ref. 89707).

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=0.01175 (0.00568 - 0.02430), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100).
Preiskategorie (Ref. 80766):   Very high.
