It also causes blooming of algae in enormous numbers thus make the water bodies, hostile for survival of fishes and other marine lives. It affects human too by release of toxins in air and water often resulting in respiratory problems, infections of gastrointestinal system, headaches and fatigue. In this type of grave circumstances, leading to outburst of population of Pfiesteria, there is an urgent need to control.
