I studied the seasonality of common mysid species in the Patos Lagoon (South Brazil) and adjacent coastal areas in one annual cycle between July 1994 and August 1995. The species composition, populational structure, temporal and spatial variation of abundance and biomass were investigated. The most abundant species were Neomysis americana, Metamysidopsis elongata atlantica and Mysidopsis tortonesei, and the less frequent species were Promysis atlantica and Metamysidopsis neritica. A strong variation in the abundance and distribution of all mysid species was linked to the seasonal fluctuation of salinity and temperature in the region. Mysids were an important contribution to the organic matter in the plankton, especially in the winter. These observations have important implications for the understanding of the dynamics and productivity of this group in coastal environments of south Brazil.
