Abstract

Red-tide is a serious global marine disaster. This years, the apparent global increase in the occurrence of red-tide has been accompanied with the enlargement of red-tide area and more harmful to ecological environment and human body. It has been an instant problem that how to manage and abate or even prevent red-tide efficiently. This report summarize the current international methods to prevent red-tide - physical, chemical and biological methods, especially the great role of marine microbes playing in the occurrence and declination of red-tide based on their population diversity, biophysiological and biochemical character diversity, ecological function diversity and heredity diversity. The authors suggest that controlling alga bloom by bacteriological method is an ideal and scientific way to manage and abate red-tide.

Key words: red-tide manage and abate, controlling alga bloom by microbes
