Revision of the author's thesis (doctoral--Freie Universitèat Berlin, 1983).

Water temperature seems to play a key role for the timing of the breeding season, abundance, and reproductive effort, whereas salinity, total suspended solids and phytoplankton biomass (measured as chlorophyll a) were associated with the distribution of the mysid species. Thus, the spatial distribution of these four mysid species within the Taieri Estuary reflects the complex linkages and interactions between favourable temperature and salinity conditions, food availability and reproduction.
