Description synthétique
Clés d'identification | Morphologie | Morphométrie
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).
