THE APPLICATION AND RESEARCH PROGRESS OF BIOREMEDIATION IN POND AQUACULTURE

The traditional pond aquaculture models have been used mostly so far, which generally have resulted in many problems: high density culture, excessive feed, water quality deterioration and disease occurrence frequently, etc. However, water exchanged or supplemented has been the traditional main method used to solve those problems, which has caused pond contaminated effluence discharge into adjacent water directly, which has resulted in series problems such as pollution diffusion, water environment deterioration, water eutrophication. To reduce pond aquaculture non-point source pollution, and ensure pond aquaculture sustainable development, this presentation introduced main bioremediation methods to restore water ecological environment in pond aquaculture, including: microbial remediation method, such as the application of microbial agents and immobilized microorganism, phytoremediation, animal-remediation, biofilm-remediation and several bioremediation techniques integration. On the base of the application prospect of bioremediation methods in pond aquaculture, biofilm-remediation method would have prosperous extension prospect, for its good and stable effect of water quality improvement, energy saving, effluence reduction, yield and profit increase.
