Abstract: | This study on the distribution of phosphate and its relation to phytoplankton biomass in Western Xiamen Harbor using marine
ecosystem enclosures to isolate the culture water from the tidal currents and salinity changes outside indicated that the
phytoplankton biomass variation closely related to dissolved inorganic phosphorus (DIP) in the seawater as described by the
equation: Chl-a]=A×e−BPO4]. The biomass changes lagged by about two days the corresponding DIP. The research also dealt with the minimal DIP concentration
for stopping diatom bloom and the possible maximal diatom biomass was estimated from the DIP external concentration in the
seawater. The threshold of DIP initiatingSkeletonema costatum red tide was calculated for use as an index to forecast its red tides. In addition, the relationships between a dinoflagellate
red tide and nutrients are discussed. The results showed that the multiplication of dinoflagellate was not entirely dependent
on the nutrients in the seawater.
