ABSTRACT: Two trials (1st Trial-46 and 2nd Trial-64 hrs duration) experiment in 8 out-door tanks (5 m3) were carried out
with similar design: 4 fish densities (0, 1, 5, and 10), 2 densities of
zooplankton (high and low) and 4 increasing levels of P and N concentrations of
nutrient enrichments. The consecutive changes of N and P concentrations were
measured at 3 (Trial 1) and 4 (Trial 2) time intervals. It was found that
nutrient uptake of the entire community, which is the differences between
initial and final concentrations, was mostly affected by the initial
enrichment. The ecological implications are discussed.
