Ecology Summary - Acanthurus triostegus

Language:

Main Ref.	Randall, J.E., 1956
Remarks	Occur in lagoon and seaward reefs with hard substrate; young abundant in tide pools (Ref. 3145, 48637). Often feeding near freshwater run-offs where certain algae grow on rocks that are grazed (Ref. 48637). Feed on filamentous algae in large aggregations. Roving herbivore (Ref. 57615). Diurnal species (Ref. 113699:31), spawning takes place between midday and dusk (Ref. 717, 38697). Also Ref. 58534, 58652.
