Zooplankton Taxa and Observations
Minimum dimensions measured.
Challenge (pre-filter)
1. Ten (10) taxa or general categories were present in the challenge samples:
copepod nauplii,
Calanoida, Polychaeta, Rotifera, diatoms, Harpacticoida, barnacle nauplii, eggs, bivalves, and
Turbellaria
2. One quarter of the adult copepods (Calanoida and Harpacticoida) were damaged, possibly due
to heavy grazing.
3. Augmentation material was present in the samples.
Treated (post filter)
1. Six (6) taxa or general categories were present in the challenge samples:
copepod nauplii,
Polychaeta, Rotifera, eggs, bivalves, and Calanoida .
