Abstract
Babylonia formosae habei is a commercially important marine gastropod species. Food particles
ingested by the planktotrophic larvae of B. formosae habei can be critical in maximizing the
larval growth and survival of this species. In this study, feeding rate responses of B. formosae


habei larvae on cultured algae were observed using a Coulter multisizer. Variations were
recorded based on the changes of different factors of influence, including varied larval stoking
density, varied types of algae, varied algae concentrations and selective feeding on mixed algae
cells of different types. Results of this study reveal some facts on the feeding of B. formosae
habei larvae: larval stoking density has negative effect on their feeding rates; larva has a higher
feeding rate on big‐sized algae than small‐sized algae; larva has a higher feeding rate on diatom

than green algae and flagellate; feeding rate of larvae increased when fed mixed algae
cells. Optimal algal concentration of the cultured algae Chlorella sp., Chaetoceros muelleri,
Isochrysis zhanjiangensis and Dunaliella tertiolecta was suggested at 20 × 104, 5 × 104, 20 × 104
and 10 × 104 cells mL−1 respectively. Results of the preset study can be important in
understanding feeding ecology of B. formosae habei larvae, and applicable for the aquaculture of
this species.
