Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 9; Radios blandos dorsales (total) : 12 - 13; Espinas anales: 3; Radios blandos anales: 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).

Nivel trófico (Ref. 69278): 4.0 ±0.66 se; based on food items.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (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).

Price category (Ref. 80766): High.
