Growth and C:N:P ratios in copepods grazing on N- or Si-limited phytoplankton bloomshey were higher in the Control treatment without nutrient additions (ca. 8.6) and up to 14 in heavily N-limited blooms. When phytoplankton blooms (chlorophyll . > 25 nmol l.) had established, wild copepods were added to the mesocosms. During Si-limitation the copepod density increased by ca. 40% in

A positive effect of low salinity on growth was also established in the experimental study. Hence, the study results suggest that under certain temperature conditions, brackish wa
