Study on nutrient limitation of phytoplankton growth in Xiangxi Bay of the Three Gorges Reservoir, China
After the impoundment of the Three Gorges Reservoir (TGR), algal blooms in the sidearm tributaries have resulted from increasing nutrient loads along the major tributaries. Field sampling and in situ nutrient addition bioassay were implemented to examine the nutrient limitation of phytoplankton grow...

The N, P, Si combined treatment increased growth by 10–50% relative to the N and P treatments from day 1 to day 4, respectively. Trace metal additions involving Fe, Zn, Mn, and Cu and/or in combination with N, P, and Si initially resulted in an extremely low growth rate which later increased significantly (p < .05) towards the end of the study.

Multiple nutrients reductions with P as primary concern are required for a lasting management solution to the risk of bloom in the TGR.
