This study clarified that the larvae of dusky grouper actively select
copepod nauplii in the size range between 2 and 12 mm in TL, and A.
salina nauplii for TL larger than 9 mm. The presence of these food
items in the rearing tanks probably enhance the quality of diet offered
to the larvae and then can determine satisfactory survival rate in the
larval rearing of dusky grouper.
