Ecology Summary - Thryssa hamiltonii

Language:

Main Ref.	Jeyaseelan, M.J.P., 1998
Remarks	Inhabits coral reefs (Ref. 58534). Presumably schooling, inshore and entering estuaries. More precise data needed, based on correct identifications (Ref. 43081). Juveniles and/or adults are found in mangrove creeks and inlets (Ref. 121464). If this is the species being referred to in Ref. 6841, then the principal food of the young would be prawns and copepods, supplemented by polychaetes and amphipods. Eggs, larval forms and juveniles occur in lower reaches of mangroves (Ref. 43081).
