Resumo: | The evaluation of Nannochloris atomliS and StichoccocllS bacillaris as nutrient sources for oyster larvae has been attempted in the present work. After a study of their grawth and size distributions, these two species were used as food for Crassostrea gigas larvae. Despite praper sizes (2.5 to 20 µm3) the larval development of Crassostrea gigas was poor. Evaluation of ingestion and digestion of both algae, by means of epifluorescence microscopy, on 2 day and 6 day old larvae showed that they were normally ingested but weakly digested. Consequently, their nutritional inadequacy for larval molluscs may be also related to their indigestibility.
