dc.description.abstract	Primary production was, for the first time, determined in freshwater bodies of Sub-Antarctic islands. Production was determined of the phytoplankton, benthic algal felts, and Potamogeton plants covered with masses of epiphytic filamentous algae. 14C tracer techniques and O2 changes were used to measure the production in situ in isolated samples. Primary production of the phytoplankton in non-biotically influenced water was minimal and IS among the lowest recorded in the world. The benthic algal felt and Potamogeton with epiphytic algae contributed most to the trophic status of the water bodies. Biological fertilization stimulated production in contaminated water.	en_ZA
