Effect of Water Purification on Succession of Plankton Community in Experimental Mesocosm System

Abstract

Experimental investigation on the succession on phytoplankton community was conducted by on-site mesocosm system. Results were as follows; 1) large size zooplankton such as Philodina erythrophthalma and Brachionua angularis, were observed in case of water glass purification system, 2) the diversity index (Shannon Index; H') was higher under complicated community structure, 3) hybrid treatment system did not show the hybrid effect on water purification effect. Therefore, it considered important that environmental improvement level should be optimized.
