Ecology
Marine; brackish; demersal; depth range 10 - 110 m (Ref. 12260). Tropical; 26°C - 29°C; 35°N - 36°S, 19°E - 137°W

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 21.0 cm FL male/unsexed; (Ref. 5525); common length : 15.0 cm TL male/unsexed; (Ref. 5450)
Found in shallow inshore coastal waters over silty bottoms (Ref. 30573, 90102). Young enters mangrove estuaries or silty reef areas (Ref. 4833, 90102). Searches for prey using a protruding pipette-like mouth or by sieving potential food through their gill rakers (Ref. 26569). Feeds on small fishes, shrimps, other crustaceans, and polychaetes. Sold fresh and dried salted; also made into fishmeal.

Estimates based on models
Preferred temperature (Ref.
123201): 24.5 - 29, mean 27.9 °C (based on 1548 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.01227 - 0.02048), b=3.04 (2.97 - 3.11), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.0 se; based on diet studies.
Generation time: 1.0 (0.9 - 1.3) years. Estimated as median ln(3)/K based on 10
growth studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (K=0.70-1.30).
Fishing Vulnerability (Ref.
59153): Low vulnerability (14 of 100).
Nutrients (Ref.
124155): Calcium = 253 [100, 601] mg/100g; Iron = 1.83 [1.01, 3.26] mg/100g; Protein = 19.5 [18.0, 21.2] %; Omega3 = 0.339 [0.185, 0.630] g/100g; Selenium = 56.4 [26.8, 116.5] μg/100g; VitaminA = 27.3 [8.9, 85.3] μg/100g; Zinc = 1.4 [0.9, 2.1] mg/100g (wet weight);
