Research on the spatial and temporal distribution of phytoplankton at Cirata Reservoir in relation to aquatic primary productivity had been conducted from March 2003 to March 2004. The aim of the research were to identify and learn spatial and temporal distribution of phytoplankton and interaction between phytoplankton and aquatic properties which affect it. Monthly sampling have been done at 5 (five) chosen stations. Two ways multivariate analysis of variance applied to identify spatial and temporal distribution of net primary productivity (NPP), biomass, orthophosphate, nitrate, ammonia, organic matter, dissolved oxygen, carbondioxide, and temperature. Multiple regression equations are applied to identify functional interrelation between net productivity and biomass with abiotic environment and interrelation between dissolved oxygen and organic matter and NPP. Result of the research showed that temporal distribution of organic matter significantly differ, but not in spatial distribution. NPP showed significant different in spatial distribution but not in temporal distribution. Biomass and NPP are higher in rainy season than dry season. Negative elimination that indicates phytoplankton development appears at the end of dry season and several months of rainy season.
