Ecology Summary - Sillago schomburgkii

Language:

Main Ref.	Hyndes, G.A., M.E. Platell and I.C. Potter, 1997
Remarks	Yellowfin whiting congregate in sandy hollows and move in schools over sand flats with the tide. They are timid fish, and bury themselves in the muddy or sandy substrate when alarmed (Ref. 6390). In Western Australia, adults prefer more open, firm sandy banks and beach areas all year, whereas in South Australia adults share the juvenile habitat during winter, moving onto the sandbanks and into deeper water during summer (Ref. 6390). Yellowfin whiting typically spend their entire life in waters less than 5 m in depth (Ref. 27657). These shallow, nearshore areas also provide nursery habitats for this species (Ref. 27657). Feed mainly on polychaetes and bivalves, which is extracted from the sediment using their downward-protruding mouth (Ref. 53687).
