Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 9; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 2 - 3; Raggi anali molli: 7 - 8.

Adults are coastal inhabitants found on soft bottoms (Ref. 44894), over sandy substrate (Ref. 12693). Juveniles are found in brackish mangrove estuaries, sometimes enter fresh water (Ref. 2847, 44894), lakes (Ref. 4323), tidal creeks (Ref. 44894) and lower freshwater reaches of rivers (Ref. 12915). Feed on small crustaceans, polychaetes and forams on sand or muddy-sand bottoms (Ref. 12915), worms and insect larvae (Ref. 12693). Length at first reproduction was reported to be around 12 cm SL, for a population in a South African estuary (D. Woodland, pers.comm. 07/13). Salted or made into fish sauce.

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Juveniles enter estuaries and mangrove areas at 1 cm SL and stay until they reach maturity, at which stage they move out to sea (Ref. 36558).

Estimates based on models

Preferred temperature (Ref. 115969): 24.8 - 29.1, mean 28.2 (based on 1220 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01230 (0.01004 - 0.01507), b=3.05 (3.01 - 3.09), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.2 se; based on diet studies.

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (K=0.7).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).

Price category (Ref. 80766): Medium.
