Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; freshwater; brackish; demersal. Subtropical; 35°N - 33°S, 99°W - 34°W
Western Atlantic: South Carolina to western Florida, USA (Ref. 26938) and the entire Gulf of Mexico to Brazil; absent from Bahamas and smaller islands in West Indies.
Length at first maturity / Size / Weight / Age
Maturity: Lm 22.0, range 18 - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 3722); common length : 30.0 cm TL male/unsexed; (Ref. 3722); max. published weight: 1.0 kg (Ref. 4699)
Inhabits shallow coastal waters and common in brackish waters (Ref. 36880), mostly over mud bottoms in mangrove-lined creeks and lagoons (Ref. 3722); often entering a considerable distance into freshwaters (Ref. 36880). Feeds on aquatic insects, crustaceans, micro-bivalves and detritus (Ref. 36880). Marketed fresh; processed into fishmeal (Ref. 3722).

Estimates based on models
Preferred temperature (Ref.
123201): 24.4 - 28, mean 26.9 °C (based on 270 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.01080 - 0.02026), b=3.03 (2.98 - 3.08), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 2.2 ±0.0 se; based on diet studies.
Generation time: 3.4 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.17-0.32).
