Ecology of Girella tricuspidata
Main Ref. Kailola, P.J., M.J. Williams, P.C. Stewart, R.E. Reichelt, A. McNee and C. Grieve, 1993
Remarks Larvae inhabit seagrass beds, moving out of them into mangrove-lined creeks and estuaries during their first year (Ref. 6390). Luderick are moderately sedentary, schooling fish. They do however, move between and within estuaries and coastal lakes, with a more pronounced movement or migration occurring prior to spawning (Ref. 5962, 28604, 28605). They are daytime foragers which rove about in large groups browsing over algal beds in shallow water (Ref. 26966).
