Zooplankton of Lake Taupo

Seasonal changes in species composition and abundance of zooplankton in Lake Taupo were measured at three sites each month from August 1974 to January 1976. The normalised data showed no differences in abundance between sites. Crustaceans comprised 50.3% and rotifers 49.7% of the zooplankton. Boeckella propinqua was the most prominent crustacean especially in spring and early summer, whereas the rotifers, dominated by Polyarthra vulgaris and Conochilus coenobasis, appeared in late summer, autumn, and winter.
