We examined the behavioural response of larvae of Echinometra lucunter reared under high and
low rations of single- and mixed-species microalgal diets to two haloclines (27/33 and 24/33) in the absence
and presence of a food patch. In the absence of a food patch, more larvae crossed the halocline in the 27/33
than in the 24/33 treatments. Also, more larvae crossed the haloclines when reared in low than high rations,
and in single- than mixed-species diets. Larval response to a food patch was stronger than the response to the
halocline. Fewer larvae crossed the halocline and more larvae were on the bottom of the cylinders in the
presence than in the absence of a food patch. More larvae were on the bottom of the cylinders with a patch when reared in low than high rations and in mixed- than single-species diets.
