Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 9; Rayons mous dorsaux (Total) : 12 - 13; Épines anales: 3; Rayons mous anaux: 11 - 12. Diagnosis: pectoral fin with 4 threadlike filaments (Ref. 57402, 81658). Pectoral fin inserted very low on body, generally somewhat longer than upper part of fin (Ref. 57402).

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. 115969): 22.3 - 28, mean 26 (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=0.00661 (0.00510 - 0.00855), b=3.09 (3.03 - 3.15), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Niveau trophique (Ref. 69278): 4.0 ±0.66 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (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.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (87 of 100).

Catégorie de prix (Ref. 80766): High.
