A note on the nutrition of Stylaria lacustris (Oligochaeta: Naididae)

  • B. Streit

Abstract

Stylaria lacustris (L.) was offered 14C-labelled algae. The ingestion rate of diatoms was 0.79 μg carbon/hour at 19°C. Diatoms (Nitzschia actinastroides) were well assimilated, green algae (Scenedesmus acuminatus) were practically not assimilated. The less assimilable algae are ingested at higher rates, indicating a regulation mechanism. Biomass doubling time was estimated to be about 3.6 days at 19°C.
