ZOOPLANKTON OF THE MHLATHUZE (RICHARDS BAY) ESTUARY: AN OVERVIEW, WITH COMMENTS ON FRESHWATER REQUIREMENTS

Abstract

The Mhlathuze estuary in its present form was established during construction of the Richards Bay harbour during the early 1970s. This paper summarises available data on the zooplankton community as part of a study on the freshwater requirements of the estuary. The zooplankton community indicates a strong marine influence. The large tidal exchange prevents the establishment of a stable estuarine zooplankton community. The possible influences of changes in freshwater input are discussed.
