Zooplankton in meromictic Big Soda Lake, Nevada, were sampled in October 1982 to determine species composition and vertical distribution relative to the oxycline. Moina hutchinsoni was most abundant in the epilimnion, but prior to migrating into the anoxic hypolimnion, it aggregated at the oxycline. Brachionus plicatilis was most abundant below the oxycline. Concentrations of Brachionus and Moina near the oxycline corresponded with peaks in bacterial productivity found by previous investigators. However, further investigation should be conducted to verify feeding by zooplankton primarily in the anoxic hypolimnion.
