Biomass of thraustochytrid protoctists in coastal water

Abstract

Abundance, cellular contents of carbon and nitrogen, and C/N ratio of planktonic thraustochytrids in the Seto Inland Sea and the coastal Hyuga-nada, Japan, were determined. Thraustochytrid cells were stained with acrflavine and counted dlrectly by epifluorescence rnicroscopy.
