A flow around plankton was investigated by a micro PIV measurement to quantify its swimming thrust in this study. The plankton is a larva of an Artemia Salina moving by flapping motion of a pair of arms. The maximum force for a forward movement arose in the power stroke phase, being obtained to be 1.1 × 10-7 N by motion analysis taking account of the added virtual mass. The friction force obtained by integration of shear stress on the body surface was 3.4 × 10-7 N. Thus, the thrust force was found to be 4.5 × 10-7 N. The converting efficiency of the thrust to the force for a forward movement was found to be 24 %.
