Abstract:This paper summarizes the relationships between the occurrences of harmful algal blooms and the eutrophication in coastal waters. In recent years, eutrophication in coastal waters has increased rapidly because of human activities. The main sources of nutrients potentially stimulating algal blooms (HABs) include terrestrial runoff, aquaculture self-pollution and atmospheric deposition. Numerous evidences from all over the world reveal the linkage between the increases in nutrient loading and the occurrences ...
