Ecological Floating Bed Applied to Control Nutrients and Cyanobacteria Bloom in the Pond Water under Intensive Aquaculture

Abstract:

An innovative ecological floating bed was designed and used for intensive aquaculture pond to improve water quality, which integrated porous ceramsite, soil substrate and plants. Put the floating bed into intensive aquaculture ponds, and investigate the nutrients and phytoplankton community structure in the ponds for a whole culture cycle. The results showed that TP and COD_Mn were significantly lowered in those ponds with innovative ecological floating bed, and their reduction rate is separately 39.52% and 22.86%; Cyanophyta and Microcystis densities were significantly reduced by 39.52% and 22.86% in July. The study also indicated that the innovative ecological floating bed is high efficiency for intensive aquaculture pond in control of the nutrient and cyanobacteria bloom.
