Maturity: L_m 29.5, range 22 - ? cm
Max length : 71.0 cm FL mannelijk / geslacht onbekend; (Ref. 6390); common length : 35.0 cm TL mannelijk / geslacht onbekend; (Ref. 2158); max. gepubliceerd gewicht: 4.0 kg (Ref. 6390); max. gerapporteerde leeftijd: 24 Jaren (Ref. 95598)

Adults favor estuarine (including mangroves), rocky reef and inshore, coastal water habitats (Ref. 5962, 27248). They flourish in seagrass areas (Ref. 6390). Ludericks are moderately sedentary, schooling fish. They are herbivorous and feed primarily on seagrasses (Ref. 6390). Filamentous algae (Ref. 26966) and cabbage weed also form part of their diet (Ref. 28607). Marketed as fresh fish (Ref. 10384).

Maturing luderick form large aggregations. Mature fish undertake 'runs' from inside the rivers and coastal lakes to the sea. The fish spawn in the surf zone and estuary mouths (Ref. 6390).

Estimates based on models

Preferred temperature (Ref. 123201): 14.6 - 23.6, mean 16.6 °C (based on 229 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00626 - 0.01752), b=3.03 (2.88 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
