On this basis, determination of whether a givenmicroalga is ingested and digested by larvae of the target
species is an important first step in assessing its suitability as a larval
food source and important in developing effective diets for hatchery
production. The aim of this study was therefore to assess ingestion
and digestion of selected live and concentrated microalgae by sandfish
auriculariae of different ages, to provide a basis for optimising hatchery
feeding protocols for this species.
