Initial food of freshwater clam Corbicula sandai and suitable diet size

Abstract

We investigated the growth and survival rate as well as the size composition of stomach contents of newly hatched plantigrade of Corbicula sandai by feeding 3 species of micro alga (Chlorella homosphaera, C. vulgaris, Skeletonema potamos ). The highest survival rate was for C. homosphaera, while C. homosphaera and C. vulgaris supported high growth rates. It was found that newly hatched plantigrade could ingest only C. homosphaera, but based on the size composition of stomach content, with growth larger dietary species (C. vulgaris and S. potamos) could be eaten.
