Body shape (shape guide): fusiform / normal.

Biology     Glossary (e.g. epibenthic)

Inhabits rivers and creeks of low to high current velocity (Ref. 36880). Found along sandy shores and over mud bottoms in shallow water, quite common in brackish mangrove-lined lagoons. Often ascends rivers more than 100 miles from the sea. Feeds on crustaceans and small fishes. Marketed fresh (Ref. 3798).

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01318 (0.00635 - 0.02739), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		4.0   ±0.67 se; based on food items.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (36 of 100). 🛈
Price category
