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

Occurs in shallow coastal waters, over sandy and muddy bottoms, sometimes in brackish habitats (Ref. 57343, 81658). Enters estuaries (Ref. 57402), occasionally caught in fresh water (Ref. 57402, 81658). Very large specimens are only found in marine waters (Ref. 81658). Feeds on crustaceans and fishes (Ref. 10799, 81658). Flesh fairly tasteful (Ref. 57402).

Estimates based on models

Preferred temperature (Ref. 123201): 22.3 - 28, mean 26 °C (based on 48 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00529 - 0.00865), b=3.10 (3.04 - 3.16), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.66 se; based on food items.
Generation time: 2.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Widerstandsfähigkeit (Ref. 120179):  mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.34-0.41; assuming tm=3-4).
Prior r = 0.57, 95% CL = 0.37 - 0.85, Based on 3 data-limited stock assessments.
